Additionally, the increased reso- lution and sensitivity give nanostructure-based diagnostics an advantage over classical methods [7, 8].

If the pathogen cannot be effectively cleared by innate immunity, the adaptive immunity, as the second line of defense in human body, will be activated. During these processes, some phagocytic cells act as antigen-presenting cells (APCs) and present specific antigens to specialized cells which are responsible for adaptive immunity, such as T cells and B cells. By this antigen-presenting process, pathogen (antigen) could be recognized by T cells and B cells and stimulate the adaptive immune response, which is specific to pathogen [10, 11]. e strong ability to eliminate pathogens makes the immune system important in most disease treatment. However, abnormal intensity of immune response, including immunosuppression and immunostimulation, will lead to disease [10]. Immunosuppression can be caused by impair- ment of any component of the immune system, which Hindawi Publishing Corporation BioMed Research International Volume 2014, Article ID 426028, 19 pages http://dx.doi.org/10.1155/2014/426028

1 Introduction

Large surface area high aspect ratio small size and uniquephysical and chemical properties in NPs enable their poten-tial applications in many biomedicine fields such as drugand gene delivery imaging photodynamic therapy andtissue engineering [1ndash3] The small size of nanoparticls offersthem the ability to overcome various biological barriers totransport and deliver therapeutic agents to the target tissueNPsmay overcome drug resistance when functionalized withtargeting moiety [4ndash6] The ldquonanophotosensitizersrdquo used inphotodynamic therapy (PDT) show higher solubility thannormal photosensitizer playing an important role in thetreatment of cancer [2] Additionally the increased reso-lution and sensitivity give nanostructure-based diagnosticsan advantage over classical methods [7 8] Compared totraditional molecular medicine NPs show advantages suchas intermixing diffusion sensoric response and ultrafastkinetics make nanomedicine a local process at the nanoscale[9] At the same time NPs will enter and interact with humanbody during these processes

results in a decreased immune function and thereby leads topathogen which cannot be effectively cleared and infection ortumorwill occur [12] Immunostimulation could enhance theability to resist pathogen but it may result in a strong adverseresponse such as autoimmune disease if it was hypersensitive

When nanomedicines are applied in vivo they act asforeignmaterials and induce the immune response immuno-suppression or immunostimulation [13] However thesemodulations of immune system caused by NPs are unde-sirable in most cases when nanomedicine is applied suchas imaging Furthermore these immune modulations byNPs could be adverse in other conditions Some nanobasedanticancer therapeutic agents show antitumor properties invitro but tumor-promoting effect in vivo [14] This oppositeeffect may be due to the disturbed anticancer immunesystem [14] However some immunomodulation propertiesare good for disease prevention and treatment such asvaccine adjuvant and antiallergy therapeutic agents [15 16]Therefore NPs play as a Janusrsquo double-face in nanomedicineapplications (Figure 1) Immunomodulating potential of NPsshould be considered seriously because it could bring unex-pected side effects in the clinical treatment Understandingof nano-immuno-interactions is critical for the safe appli-cation of engineered NPs in medicine and safe design ofnanomedicine

In this review we focus on the immunomodulatingeffects of NPs used in nanomedicine on immune system(Table 1) Effects of physicochemical properties of NPs onimmune interactions and the underlying mechanisms arealso reviewed

2 NPs Candidates Used in Nanomedicine

Nanotechnology has a great potential in medicine applica-tions such as medical diagnostics [60] and therapy [61] Asan inorganic fluorophore quantum dots (QDs) have pho-tostability which makes them ideal candidates for imagingtools in vivo [62] Recent study showed a technique to tracklymph flow in real time using quantum dots optical imagingin mice [22] In addition superparamagnetic iron oxideNPs (SPION) were also applied to trace neurodegenerativediseases by magnetic resonance imaging (MRI) [63] Somecarbon-based NPs are also applied in clinical use Carbonnanotubes (CNTs) have unique physical properties such aselectrical thermal and spectroscopic properties whichmakethem an advantage in detection and therapy of diseases [64]It was reported that CNTs could prolong survival of tumor-bearing animals [65] Graphene has good biocompatibilitybiofunctionalization and its unique mechanical electronicand optical properties for imaging and cancer phototherapy[66] And it was demonstrated that graphene oxide (GO)have antibacterial properties [67] making them candidatesas antibacterial agent Besides graphene derivatives are alsogood candidates for drug delivery as they can bind witharomatic drugs through120587-120587 stack andor van derWaals inter-actions [66] Gold NPs (GNPs) are also potential materials incancer therapies and imaging due to their biocompatibilityplasmon resonances and diverse functionalizations [68] It

is promising to apply GNPs to targeted therapy of cancer[69] and overcome drug resistance [6] Silver NPs (AgNPs)are important metal nanomaterial They have antibacterialantifungal and antiviral effects [70] Lipid NPs and liposomehave been widely applied for drug delivery because of theirimproved drug potency and low off-target effects [71] OtherNPs such as polymer CeO

2 silica NPs dendrimer and

protein NPs are also used in nanomedicine [72ndash78]As foreign materials NPs could be recognized by the

immune system and induce immunosuppression or immun-ostimulation when used as nanomedicine How to utilizeor control these immunomodulation effects is largely basedon NPsrsquo different applications NPs with immunosuppressioneffects might be used as anti-inflammatory or antiautoim-mune disease therapeutic agents On the contrast NPs whichactivate immune systemmight be used as vaccines or vaccineadjuvants An advanced nanomedicine in drug delivery orimaging should not induce undesired immune-activation orimmunosuppression effectThe detailed immunomodulationeffects of these NPs in nanomedicine applications are dis-cussed below

(reduced T-cell-dependent antibody against sheep erythro-cytes and T-cell proliferative ability and decreased naturalkiller cell activity) This suppression was accompanied byincreased spleen gene expression of interleukin-10 (IL-10)which is an anti-inflammatory cytokine and NAD(P)H oxi-doreductase [17] Other studies showed that pharyngeal aspi-ration of SWCNTs (40 120583gmouse) in BALBc mice inducedpulmonary inflammation and suppressed the responsivenessof T cell 7 days postexposure This immunosuppression wasassociated with the direct effects of SWCNTs on DCs [19]

312 Fullerene As a strong free-radical scavenger [79]fullerene has anti-inflammatory effects The antioxidativeanti-inflammatory activities of novel fullerenes have beenreported [80] Fullerene could suppress Ag-driven type Ihypersensitivity when human MCs and peripheral bloodbasophils were preincubated with C

60fullerenes This sup-

pression involved decreasing the level of reactive oxygenspecies (ROS) [16] In aMC-dependentmodel of anaphylaxisfullerenes prevented the release of histamine [16] In addi-tion polyhydroxylated fullerene derivatives might protectagainst oxidative stress in ischemia-reperfused lungs [81]C60

also suppressed the tumor necrosis factor alpha (TNF-120572) induced production of proinflammatory cytokines in vitroand inhibited the arthritis in vivo [27] Other studies indifferent animalmodels also showed the immunosuppressioneffects of fullerenes For example hydroxylated fullerenescould interfere with the innate immune system in fatheadminnow [31] Nanocrystalline fullerene showed cytotoxicityand promotive effects on tumor cell growth in vitro and invivo respectively which might be due to the suppression ofanticancer immune response of mice by fullerene [14]

313 Gold NPs The anti-inflammatory properties citrate-coatedGNPswere also reported Citrate coatedGNPs (21 nm)did not cause detectable organ or cell toxicity in mice [37]Studies also indicated that citrate-stabilized 5 nm and 15 nmGNPs inhibited cellular responses induced by interleukin 1beta (IL-1120573) and showed anti-inflammatory activity [38]

314 Silver NPs The studies on the immunotoxicity ofAgNPs are very limited AgNPs induced ROS and inflamma-tion [82 83] indicating its potential interference of immunesystem AgNPs (22 nm) exposure caused the downregulationof expression of Malt1 and Sema7a genes which were associ-ated with immune cell function followed by aberrant T celldifferentiation [39]

315 Magnetic NPs Some in vitro studies showed that ironoxide NPs did not induce inflammatory response on humanmonocyte-macrophages [84] and aortic endothelia cells [85]However high doses of iron oxide NPs may induce oxidativestress [86] When treated with PVA-coated SPION humanmonocyte-derived DCs showed a decreased antigen process-ing and CD4 (+) T cell stimulation capacity [87] Thesestudies suggested the potential immune impact of magneticNPs The immunomodulation of the iron oxide NPs wasmuch more complex in vivo Intratracheally administration

of high dose (4 times 500 120583gmouse) and intermediate dose (4 times250 120583gmouse) of iron oxide NPs with a diameter of 35 plusmn14 nm or 147 plusmn 48 nm inhibited the allergic Th2-dominatedresponse induced by ovalbumin (OVA) The low dose (4 times100 120583gmouse) of iron oxide particles (147 plusmn 48 nm) hadno significant effect while the low dose (4 times 100 120583gmouse)of particles (35 plusmn 14 nm) had an adjuvant effect on theTh2 response to OVA [45] A single intratracheal instillation(250 375 or 500120583gmouse) or four-time repeated instillation(500120583gmouse times 4) showed that both NPs induced lunginflammation and decreased pulmonary immune responsesagainst sheep erythrocytes In another study intravenouslyadministration of iron oxide NPs (587 nm) in doses le 10mgironkg shifted the Th1Th2 immunobalance towards theTh2-dominant direction and suppressed the delayed-typehypersensitivity in OVA-sensitized mice [44] Furthermorerepeated instillations resulted in a reduction of inflammationthan single instillation [88]

316 CeO2NPs Due to their reducibility cerium oxide NPs

(nanoceria) were found to have the ability to reduce ROSandmay be used as a novel therapeutic tool for inflammationtreatment [73] Some in vitro studies indicated that nanoceriawith a small diameter caused a significant anti-inflammatoryeffect [73 89 90] For example nanoceria with a diameterof 3ndash5 nm scavenged free radicals inhibited inflammatorymediator production in J774A1 the murine macrophages[73] A recent study reported that the same size of nanoceriainducedAPCs to secrete IL-10 and induced aTh2-dominatedT cell proliferation The nanoceria (5ndash8 nm) showed aneffective antioxidant property in cardiac progenitor cells andprotected the cardiac progenitor cells from H

2O2-induced

cytotoxicity In addition in vivo investigation on immunecells of the sea urchin indicated that nanoceria suppressed theinnate immunity when force-fed 1mL 10minus2 gL 50ndash60 nm ofnanoceria [91]

317 Quantum Dots As efficient energy donors [92] QDscan induce the generation of ROS by transferring energyto nearby oxygen molecules In vitro studies have shownthat QDs induced production of ROS and led to multipleorganelle damage and cell death [93 94] Preexposure toa dose at 10minus7 to 10minus3 120583gmL CdTe QDs suppressed theimmune responses of J774A1 macrophage to bacteria byreducing NO TNF-120572 KCCXCL-1 and IL-8 production[95] These in vitro studies suggested that QDs might havehigh immunotoxicity In vivo studies also showed similarresults CdTe QDs (16 4 and 8mgL for 24 h at 15∘C)significantly decreased the viability of hemocytes as wellas number of hemocytes capable of ingesting fluorescentbeads in Elliption complanata mussels [50] The immuno-suppression was also observed in Juvenile rainbow troutWhen 5 10 and 20 nM CdSCdTe QDs were exposed toJuvenile rainbow trout for 96 h at 15∘C the leukocyte countsviability and both resting and active phagocytic activity weresignificantly reduced [51] QDs affected the proliferation ofimmune cells but did not induce immune response includingcytokine production [96] Size of QDs aggregates may affect

the immune response of QDs Large CdSCdTe QDs aggre-gates (25ndash100 nm) reduced phagocytosis more than smallerNPs (lt25 nm) on bivalves (Mytilus edulis and Elliptio com-planata) and fish (Oncorhynchus mykiss) [97] Thereforecaution is needed to overcome this barrier when QDs areapplied in clinical treatment

318 Polymeric NPs In vivo studies indicated that somepolymeric NPs inhibited inflammation but had no effect onhost immunity [54 98] NPs produced by particle replicationin nonwetting template technology remained in the lungs forup to 7 days without triggering host immunity after intra-tracheal administration of 50 120583gmouse [98] PolystyreneNPs (50 nm) inhibited lung inflammation by intratrachealadministration of 200120583gmouse after allergen challengeThisinhibition was due to the modulation of DCs functions NPsinhibited expansion of CD11c+MHCIIhi DCs in the lungs anddraining lymph node and allergen-laden CD11bhiMHCIIhiDCs in the lungs [54] In addition polystyrene particles havethe potential to halt the disease process in autoimmunityFor example antigen-decorated polystyrene particles with adiameter of 500 nm induced T-cell tolerance and amelioratedexperimental autoimmune encephalomyelitis by inactivatingpathogenic T cells [55]

32 Immunostimulation

321 CarbonNanotubes CNTs induced immunostimulationin vitro and in vivo The oropharyngeal aspiration of MWC-NTs (1 2 and 4mgkg) in C57BL6 mice induced inflam-mation (30 days postinstillation) in lungs [20 21] MWCNTswere translocated progressively into the spleen reached amaximumof 48 h after intraperitoneally (ip) administrationwhich caused the lymphocytic hyperplasia and increasedoxidative stress in the spleen [99] Subcutaneous adminis-tration of MWCNTs with total dose of 10mg for two scinjections in BALBc mice induced acute immunologicalreactions for 1 week (activation of complement and increasedproinflammatory cytokines) However the accumulation ofMWCNTs and injury was not observed in spleen [24]MWC-NTs injected intravenously activated Th2 immune responseby elevating Th2 cytokines and increasing number of CD4+and CD8+ T cell in the spleen [23] In other studies CNTsshowed allergy adjuvant effect in inflammatory mass Forexample SWCNTs andMWCNTs exhibited adjuvant activityto the OVA-sensitized mice [25 100] MWCNTs aggravatedasthma and induced fibrosis in OVA-sensitized lungs butshowed no response with healthy pulmonary The resultsindicated that these NPs could bring harm to asthma patientsbut not health ones [25] In recent in vitro studies MWCNTsincreased the release of a series of cytokines in peripheralblood mononuclear cells (PBMCs) from healthy donorsafter stimulation with toll-like receptor (TLR) agonists orT cell mitogen However MWCNTs suppressed immuneresponses in PBMCs frommite-allergic subjects These stud-ies suggest that MWCNTs may either stimulate or suppressimmune system depending on their immune cell target[101]

322 Graphene GO could induce healthy DCs to differen-tion and maturation at varying degrees [102] but suppressthe antigen-delivering ability of OVA-loaded DCs to Tlymphocytes [103]This inhibitionwas associatedwith down-regulation of subunit LMP7 of immunoproteasome in cellswhich is responsible for antigens processing in DCs [103]Whenmacrophage cells RAW2647 were incubated with GOtoll-like receptor (TLR4TLR9-) 6 modulated autophagy andinflammatory responses occurred [104] In addition PVP-coated GO exhibited lower immunogenicity than GO on theaspect of inducing maturation and differentiation of DCs[102] PVP-coated GO enhanced the physiological activityof macrophages which showed anti-phagocytosis abilityagainst macrophages and delayed the apoptotic process ofT lymphocytes [102] This advantage makes PVP-coated GOa promising candidate of immunoadjuvant The effect oftwo sizes (2120583m and 350 nm) of the GO in response tomicrophages was investigated [105] These two NPs hadequal uptake amount in macrophages but microsized GOinduced stronger inflammation responses and showed diver-gent intracellular locations compared to nanosized GO [105]This result demonstrated that lateral dimension of GO playsan important role in the regulation of cellular responsesRecent studies demonstrated that intravenously deliveredgraphene nanosheets induced site-specificTh2 inflammatoryresponses in the lungs via the IL-33ST2 axis [23] Thiseffect may cause host defense and exacerbation of allergicdiseases However more studies in vivo are needed to assessand eliminate the potential immunomodulation of graphene-based materials to ensure their safety for applications inbiomedicine

323 Fullerene Some studies showed that C60have immun-

ostimulatory properties [28ndash30 103 106] After instillationC60upregulated gene expression of various proinflammatory

cytokines (IL-1 TNF-120572 IL-6) andTh1 cytokines (IL-12 IFN-120574) in mice Besides inflammation C

60could activate the

immune system The carboxyfullerene could prolong theinfiltrating neutrophils to enhance the bactericidal activity ofneutrophils [30] Other studies indicated that fullerene mayenhance the ability of DCs to stimulate T cells and further-more activated cells of innate immune system by enhancingproduction of IL-6 and an activation of natural killer (NK)cells [103 106] In addition immunization of mice with aC60

fullerene derivative conjugated to bovine thyroglobulincould produce a population of fullerene-specific antibodieswhich included a subpopulation that cross-reacted with a C

324 Gold NPs GNPs with different surface modifica-tion showed different immunogenicity in organisms Theimmunogenicity of GNPs coated with C-terminal 19 kDafragment of merozoite surface protein 1 (MSP-1

19) was an

important vaccine candidate In this study GNPs showedpoor immunogenicity in mice but enhanced antibodyresponse when formulated with alum [15] However GNPscoated with monosaccharide or disaccharides could initiatethe immune response by activating the macrophages [107]

BioMed Research International 9

Some studies indicated that high concentrations of PEGcoated on GNPs could induce antibody production andtrigger immune responses High doses of injected PEG-coated GNPs were cleared through these mechanisms [3233]

GNPs can also induce inflammatory responses in vivoWell-dispersed PEG-coated GNPs (13 nm) can be recognizedby host defense mechanism and induce acute inflammationand apoptosis in the liver [34] If inflamed tissues are exposedstronger immune responses may be induced [108] Whenexposed to sensitized mice 40 nm GNPs could lead to athreefold increase in airway hyperreactivity and increase thenumber of neutrophils and macrophages [36]

325 Silver NPs Intratracheal instillation of AgNPs with adiameter of 5225 plusmn 2364 nm could enhance the respiratoryimmune function through oxidative stress and inducedinflammation in the respiratoryWhen alveolar macrophageswere activated by AgNPs to cause phagocytosis the alve-olar macrophages generated ROS and free radicals whichresulted in oxidative stress The normal function of alveolarmacrophages and epithelial cells was subsequently affectedThis led to oversecretion of cytokines and oxides which thencaused the stimulation of the respiratory immune function[40] These opposite results may be due to the differentdiameters of NPs Covalent conjugation of Ag to solid corenanobeads with different diameters ranging from 002 to2 120583m was found localized into DCs (DEC205+ CD40+CD86+) in draining lymph nodes and induced high levels ofIFN-120574 production and high antibody titers in tumor-bearingmice [41]

326 CeO2NPs Instillation of 100 120583g nanoceria with a

diameter of 8 nm in C57BL6 mice revealed that the NPsinduced inflammation in pulmonary system by activatingMCs [46] Other studies using bigger sizes showed the sameeffect Single intratracheal instillation of 20 nm nanoceriaat 015ndash7mgkg caused a dose-dependent inflammation andlung injury [47] The intratracheal instillation of 20ndash30 nmnanoceria (241m2g) with doses of 50 and 150 cm2mouseinduced both acute and chronic neutrophilicmildly cyto-toxic inflammation [48] Inhalation of 55 nm nanoceriawith an average aerosol concentration of 641mgm3 for 4 hinduced cytotoxicity via oxidative stress and led to a chronicinflammatory response including up regulation of IL-1120573TNF-120572 and IL-6 [49]

327 Silica NPs 30 nm amorphous silica NPs were inves-tigated in PBMCs and purified monocytes These NPscould induce inflammatory response as production of IL-1120573 IL-8 and ROS This result indicated the potential ofsilica NPs to evoke innate immune reactions [109] Otherreports showed that 30 and 70 nm silica NPs inducedhigher production of TNF-120572 in RAW2647 cells and strongerinflammatory responses (IL-5uarr IL-6uarr MCP-1uarr keratinocytechemoattractantuarr) than 300 and 1000 nm particles in vivo

through intraperitoneally injection The 70 nm particle-induced TNF-120572 production was dependent on the produc-tion of ROS and activation of mitogen activated proteinkinases (MAPKs) However modification of carboxyl groupson 70 nmparticles dramatically suppressed the inflammatoryresponses [52] As well Kupffer cells stimulated by 15 nmsilica NPs released large amounts of ROS TNF-120572 and NOThe viability of Buffalo rat liver (BRL) cells was reduced aftercultured with silica NP-stimulated Kupffer cells The authorsalso studied the intravenous injections of silica NPs with asingle dose of 50mgkg It caused hepatic inflammation andoxidative stress [53]

328 Polymeric NPs Polymer-based NPs were shown to beeffective adjuvants in vaccination [72 110 111] These poly-mers have the ability to activate cellular immune responsesin the host [112] For example N-trimethyl chitosan-mono-N-carboxymethyl chitosan (TMCMCC) NPs appeared tobe very promising as an adjuvant and delivery system forantigens Intranasal vaccination with tetanus toxoid loadedTMCMCC NPs (2835 plusmn 25 nm) was shown to induceboth the mucosal and systemic immune response (enhancedantibody response) The enhanced immunoglobulin G (IgG)immune response could be explained by the sustained releaseof the toxoid [113]

Some polymer NPs were reported to activate immunesystem through modulating the activation and capabilityof immune cells such as dendritic cells and T cells [114ndash116] Amphiphilic NPs possessed pathogen-mimicking prop-erties by activating DCs similar to lipopolysaccharide (LPS)thus it has the ability to activate innate immune response[114] Poly(methyl vinyl ether-co-maleic anhydride) NPs(149 plusmn 2 nm) activated DCs through TLR stimulation ininnate immune system [115] As well the sulfonate (245 nm)and phosphonate-functionalized (227 nm) polystyrene NPsinduced the maturation of immature DCs and significantlyenhancedT cells stimulatory capacity indicating a shift toTh1response [116]

329 Other NPs Dendrimers have the ability to stimu-late immune system and can be used as potential candi-dates for vaccines [76] Maltose-functionalized dendrimer-peptide complex is a potential DC-based vaccine candi-date by stimulating DC and activating the immune system[117] Research also showed that Pan-DR-binding epitope-derivatized-dendrimer could reduce the effective dose ofliposomal amphotericin B inmurine cutaneous leishmaniasisand enhance adaptive immunity by activating strong parasitespecific T-cell responses [56]

Protein NPs have shown immunostimulating propertiesin recent studies [118ndash120] Self-assembled protein NPs thatdisplayed epitopes of the repeat sequence in circumsporo-zoite protein of plasmodium falciparum (PfCSP) elicited astrong immune response against PfCSP [119 121] In additionprotein NPs mimic viruses have the ability to facilitate DCsactivation and cross-presentationThese proteinNPs codeliv-ered with peptide epitopes to DCs showed an increased andprolonged CD8+ T cell activation [120]

A lipidNPwas investigated in aDNAvaccine applicationThis NP which decorated with stearyl-conjugated KALAan 120572-helical peptide (sequence WEAKLAKALAKALAK-HLAKALAKALKACEA) showed enhancement of transgeneexpression this enhancement was closely related to immune-activation [122] A cationic solid-lipid NP was used as a vac-cine to deliver a DNA vaccine against visceral leishmaniasisHigh levels of IFN-120574 and low levels of IL-10 production weredetected in BALBc mice after administration of the DNAvaccine delivered by this cationic solid-lipid NP This NPinduced a strongTh1 immune response indicating its poten-tial as therapeutic agent against visceral leishmaniasis [57]Nanolipoprotein conjugated with TLR agonists monophos-phoryl lipid A or CpG oligodeoxynucleotides significantlyenhanced the immunostimulatory profiles compared to theagonists alone Moreover the BALBc mice pretreated withCpGnanolipoprotein coloaded nanoconstructs but not CpGalone survived a lethal influenza challenge [58] Researchalso indicated that intravenous injection of liposome-DNAcomplexes elicited production of IFN-120572 and IFN-120573 in vivowhich suggested that the liposome-DNA complexes caninduce inflammation and cause systemic toxicity [123] Inanother study it was reported that Doxil an PEGylatedliposomal formulation of doxorubicin may cause hyper-sensitivity reactions while the standard doxorubicin didnot indicating that liposomes might be responsible for thishypersensitivity [59] It was speculated that the complementsystem activation by Doxil may play a key role in this effect[59]

4 The Factors Affecting Immunomodulationof NPs

Many factors contribute to immunomodulation of NPs Thenature of NPs such as composition surface chemistry sizeshape and protein-binding ability dominates these interac-tions Besides individual difference and exposure route alsocontribute to immunomodulation of NPs

41 Composition Composition of NPs lays a vital role inthe interactions between NPs and immune system Forexample QDs showed high immunotoxicity [50 51] becausethey release heavy metal ions Some other NPs exhibit lessimmunotoxicity [17 23 39 44 54] immunogenic [15 32]or no effect [45] The different core of NPs gave differentreaction in allergy mass For example CNTs and GNPsshowed adjuvant effect and led to hypersensitivity in theseallergy masses [25 26 36] while fullerene often showedimmunosuppression [14 31]

42 Surface Chemistry For NPs with the same compositionsurface properties may also affect the immune system Engi-neered NPs such as CNTs fullerenes GNPs and silica NPscan be modified with diverse surface chemistry This mayalter their immune response both in vitro and in vivo

Eighty diversely functionalized multiwall nanotube(MWNT) induced different levels of protein bindingcytotoxicity and immune responses (Figure 2) [124] The

modification of MWCNTs significantly alleviated nuclearfactor kappa B (NF-120581B) activation and reduced immuno-toxicity ofMWCNTs in BALBcmice [125] Carboxyfullereneactivated immune system of C57BL6 mice by prolongingthe infiltrating neutrophils to enhance the bactericidalactivity of neutrophils [30] while hydroxylated fullerenesinterferedwith the innate immune system in fatheadminnow[31] MWCNTs-PEG induced less generation of ROS andcytotoxicity in macrophages than MWCNTs-COOH whichwas in correspondence with the lower cellular uptake ofMWCNTs-PEG [126] The monolayer-protected GNPs invivo were studied Simple place-exchange reactions withinthe monolayer by short chain mercaptotetraethylene glycolhave been used The short chain at lower concentrations didnot trigger the immune system to produce anti-PEG antibody[33] However high concentration mixed monolayer coatedNPs initiated an immune response [32] Silica NPs (70 nm)induced strong inflammation by intraperitoneal injectionbut these inflammatory responses could be dramaticallysuppressed by surface modification by carboxyl groups [52]The toxicity of porous silica NPs to immune cells was surfacechemistry and surface charge-dependent Compare tosurface hydrophobicity surface charge had stronger impacton NPsrsquo immunotoxicity in vitro and in vivo Positivelycharged hydrophobic NPs showed more DNA damage thannegatively charged hydrophilic NPs [127]

43 Size Size is another important parameter that deter-mines the interaction with organisms When examinedimmunity is induced by a series of differentially sized (2040 49 67 93 101 and 123 nm) polystyrene nanobeads IFN-120574 induction from CD8+ T cells was limited to 40 and 49 nmbeads while 93ndash123 nmbeads inducedCD4+ T cell activationand increased IL-4 levelThese results showed that the size ofnanobead for vaccination could influence the type 1type 2cytokine balance This would be useful in the developmentof vaccines against common human pathogens [128] 200 nmNPs increased more antigen-specific polyfunctional CD4+ Tcells as compared to 30 nm NPs The immunoactivity of dis-accharides coated GNPs is strongly dependent on size Theyused 2 and 5 nm GNPs coated with disaccharides These NPsactivated the macrophages and induced the proliferation of Tcells and the increase of IL-2 levels The 5 nmNPs performedfar better than 2 nmones (increasedAPC proliferationMHCII expression T cell proliferation and IL-2 expression) [107]Other researches indicated that single instillation (250 375or 500 120583gmouse) of 35 plusmn 14 nm iron oxide NPs inducedhigher levels of inflammation and immunodepression than147plusmn48 nm ones [88] Repeated intratracheal administrationof high dose (4 times 500120583gmouse) and intermediate dose (4 times250 120583gmouse) of the same NPs inhibited the allergic Th2-dominated response induced by OVA The low dose (4 times100 120583gmouse) of 147 plusmn 48 nm iron oxide particles had nosignificant effect but the low dose (4 times 100 120583gmouse) of 35plusmn14 nm particles had an adjuvant effect on theTh2 response toOVA [45] Aggregate size may also affect the immunotoxicityof QDs The toxicity of CdSCdTe QDs was size dependentLarge CdSCdTe QD aggregates (25 nmndash100 nm) reduced

44 Protein Binding When NPs enter the body throughinjection they firstly interact with blood [129] The plasmaprotein binding on the NPs surface such as apolipoprotein Eand transferrinmay contribute to the activationdeactivationof receptor-dependent signaling [130]

The amount and types of proteins adsorbed on the NPsaffect the interactions of cells and NPs and the biologicalresponses [131 132]The composition surface characteristicsand shape of NPs affect the manners that the proteinsbind to them [129 133ndash136] The blood proteins adsorbedonto the NPs include immunoglobulins apolipoproteins andproteins of the complement system among many othersThese proteins may act as signals for immune responses [137138] Furthermore NPs may induce conformational changesin the structure of adsorbed proteins Negatively chargedpoly(acrylic acid-) conjugated GNPs bound with fibrinogenand induced the unfolding of this protein which promotedinteraction with Mac-1 an integrin receptor This activationincreased the NF-120581B signalling pathway and released inflam-matory cytokines [139]

45 Exposure Route Exposure route is another factor affect-ing the immunomodulation ofNPsTheoutcomes of immuneresponse are dependent on entrance of NPs In the lungsDCs pulmonary epithelium and macrophages play animportant role in handling foreign materials In the bloodleukocyte such as neutrophil eosinophil basophil lympho-cyte and monocyte play a vital role Single intratrachealinstillation of 500120583gmouse iron oxide NPs (35 plusmn 14 nmand 147 plusmn 48 nm) induced lung inflammation and decreasedpulmonary immune responses against sheep erythrocytes[88] Pharyngeal aspiration of SWCNTs modified systemicimmunity by modulating DCs function [19] Intravenouslyadministration of iron oxide NPs (587 nm) could sup-press the infiltration and functional activity of Th1 cellsand macrophages [44] Intravenous injection of graphenenanosheets activated a Th2 immune response which con-sisted of neutrophilic influx and a significant increase inIL-5 IL-13 IL-33 in the bronchoalvelar lavage fluid [23]The dosage of administration is also important Intratrachealinjection of iron oxide NPs (35 plusmn 14 nm) inhibited theallergic response in OVA-sensitized mice at a dosage of 4 times250120583gmouse or 4 times 500 120583gmouse but showed adjuvanteffect at a dosage of 4 times 100 120583gmouse [45]

5 The Mechanisms of ImmunomodulationInduced by NPs

NPs interact with both innate and adaptive immune cellsaffect their functions and disturb immune system (Figure 3)

oxidative abilities than normal particles [140] Oxidativedamage induced by NPs is an important factor of immuneimbalance [11] Many types of NPs have been shown toproduce ROS in vitro and in vivo and enhance immunefunction or inflammatory response [40 49 53 86 141] Freeradical-induced tissue damage plays an important role ininflammatory diseases [142 143]

The signal pathway to induce ROS and mediate inflam-mation was reported Among them TLR4 signaling pathwaywas documented GO could induce intracellular ROS whichdecreased the viability of macrophages and induced necrosisby a TLR4 signaling pathway (Figure 4) [144] TLR is areceptor of the innate immune system and innate immunitycould be triggered by stimulating TLRs and lead to strongadaptive immunity [115] Activation of the TLR pathwayscould induce chronic inflammation and ROS [145] Resentresearch indicated that quantum dots could activate myeloiddifferentiation primary response gene 88 (MyD88 which isan adapter protein to activate NF-120581B) dependent-TLRs inmcrophages and activated NF-120581B [146]

NF-120581B pathway is another key regulator of immuneresponse [125 147ndash149] As an important regulator of proin-flammatory gene expression synthesis of cytokines suchas IL-1120573 IL-6 IL-8 and TNF-120572 is mediated by NF-120581B

Activation of NF-120581B may induce human inflammatory dis-eases [150 151] It was reported that negatively chargedpoly(acrylic acid-) conjugated GNP activated the NF-120581Bsignalling pathway in THP-1 cells The cells released inflam-matory cytokines including TNF-120572 and IL-8 [139] Andcitrate-stabilized 10 nm GNPs could induce activation of anNF-120581B regulated luciferase reporter in murine B-lymphocytecell line (CH12LX) and altered the cell function [152]

NPs may also disturb the immune balance by inappro-priate maturationactivation of APCs such as DCs [26 153]Intratracheal instillation of 43 nmMIONs the alveolar regionof BALBc mice could generate a significant number ofexosomes These exosomes were quickly eliminated from thealveolar region into systemic circulation and transferred theirsignals to the immune system which resulted in maturationof DCs and activation of splenic T cells and the exosome-induced T-cell activation is more efficient in OVA-sensitizedmice [42 43] Cytotoxicity to immune cells may contribute toimmunosuppression of NPs QDs may decrease the viabilityof hemocytes in Elliption complanata mussels [50] andreduced phagocytosis on bivalves and fish [97]

Recent reports indicated that NPs could modulate thehomeostasis of immune cells including the shift of Th1Th2balance [43 44 89] and monocyte homeostasis [154] Forexample magnetic iron oxide NPs activated the T cellsinduced a Th1 polarization and aggravated inflammation[43]Other studies showed that SWCNTs accentuatedThcellsimmunity includingTh2 (IL-4uarr IL-5uarr and IL-13uarr) andTh17

(IL-17Auarr IL-23uarr) The inappropriate maturationactivationof APCs such as DCs might be responsible for these accen-tuated Th cells immunity [26 153] The normal immunesystem keeps a Th1Th2 balance in order to achieve anappropriate immune response Selectively activating Th1 orTh2 cells results in immune deviation and breaks the balanceof immune system In addition MWCNTs could selectivelydecrease phagocytosis-competent monocytes and promoteadhesion of the phagocytosis-incompetent monocytes inblood flow [154]

6 Conclusion

The immune response of NPs is like a double-edged swordin nanomedicine applications by bringing both benefits andharms We should take advantage of the benefits from theimmunomodulating properties of NPs and on the otherhand avoid the undesirable immune responses in order tominimize the systemic side effects The factors affecting theimmune response are complex including particle compo-sition size surface chemistry plasma protein binding andexposure route Investigation of the relationship betweenproperties of NPs and systemic immune response is crucialfor their application in medicine and other areas Althoughtreatments of acute and long-term immune toxicities havebeen developed current approaches of prediction preven-tion and treatment of nanoimmunomodulation are stilllacking encouraging further in-depth studies

results in a decreased immune function and thereby leads topathogen which cannot be effectively cleared and infection ortumorwill occur [12] Immunostimulation could enhance theability to resist pathogen but it may result in a strong adverseresponse such as autoimmune disease if it was hypersensitive

When nanomedicines are applied in vivo they act asforeignmaterials and induce the immune response immuno-suppression or immunostimulation [13] However thesemodulations of immune system caused by NPs are unde-sirable in most cases when nanomedicine is applied suchas imaging Furthermore these immune modulations byNPs could be adverse in other conditions Some nanobasedanticancer therapeutic agents show antitumor properties invitro but tumor-promoting effect in vivo [14] This oppositeeffect may be due to the disturbed anticancer immunesystem [14] However some immunomodulation propertiesare good for disease prevention and treatment such asvaccine adjuvant and antiallergy therapeutic agents [15 16]Therefore NPs play as a Janusrsquo double-face in nanomedicineapplications (Figure 1) Immunomodulating potential of NPsshould be considered seriously because it could bring unex-pected side effects in the clinical treatment Understandingof nano-immuno-interactions is critical for the safe appli-cation of engineered NPs in medicine and safe design ofnanomedicine

In this review we focus on the immunomodulatingeffects of NPs used in nanomedicine on immune system(Table 1) Effects of physicochemical properties of NPs onimmune interactions and the underlying mechanisms arealso reviewed

2 NPs Candidates Used in Nanomedicine

Nanotechnology has a great potential in medicine applica-tions such as medical diagnostics [60] and therapy [61] Asan inorganic fluorophore quantum dots (QDs) have pho-tostability which makes them ideal candidates for imagingtools in vivo [62] Recent study showed a technique to tracklymph flow in real time using quantum dots optical imagingin mice [22] In addition superparamagnetic iron oxideNPs (SPION) were also applied to trace neurodegenerativediseases by magnetic resonance imaging (MRI) [63] Somecarbon-based NPs are also applied in clinical use Carbonnanotubes (CNTs) have unique physical properties such aselectrical thermal and spectroscopic properties whichmakethem an advantage in detection and therapy of diseases [64]It was reported that CNTs could prolong survival of tumor-bearing animals [65] Graphene has good biocompatibilitybiofunctionalization and its unique mechanical electronicand optical properties for imaging and cancer phototherapy[66] And it was demonstrated that graphene oxide (GO)have antibacterial properties [67] making them candidatesas antibacterial agent Besides graphene derivatives are alsogood candidates for drug delivery as they can bind witharomatic drugs through120587-120587 stack andor van derWaals inter-actions [66] Gold NPs (GNPs) are also potential materials incancer therapies and imaging due to their biocompatibilityplasmon resonances and diverse functionalizations [68] It

Figure 1 The immunomodulation of NPs presents a Janusrsquo double-face in nanomedicine applications On one hand the effects to theimmune systemmay benefit treatment of disease through enhancingimmune response On the other hand the immunomodulation ofNPs may bring harm

is promising to apply GNPs to targeted therapy of cancer[69] and overcome drug resistance [6] Silver NPs (AgNPs)are important metal nanomaterial They have antibacterialantifungal and antiviral effects [70] Lipid NPs and liposomehave been widely applied for drug delivery because of theirimproved drug potency and low off-target effects [71] OtherNPs such as polymer CeO

2 silica NPs dendrimer and

protein NPs are also used in nanomedicine [72ndash78]As foreign materials NPs could be recognized by the

immune system and induce immunosuppression or immun-ostimulation when used as nanomedicine How to utilizeor control these immunomodulation effects is largely basedon NPsrsquo different applications NPs with immunosuppressioneffects might be used as anti-inflammatory or antiautoim-mune disease therapeutic agents On the contrast NPs whichactivate immune systemmight be used as vaccines or vaccineadjuvants An advanced nanomedicine in drug delivery orimaging should not induce undesired immune-activation orimmunosuppression effectThe detailed immunomodulationeffects of these NPs in nanomedicine applications are dis-cussed below

(reduced T-cell-dependent antibody against sheep erythro-cytes and T-cell proliferative ability and decreased naturalkiller cell activity) This suppression was accompanied byincreased spleen gene expression of interleukin-10 (IL-10)which is an anti-inflammatory cytokine and NAD(P)H oxi-doreductase [17] Other studies showed that pharyngeal aspi-ration of SWCNTs (40 120583gmouse) in BALBc mice inducedpulmonary inflammation and suppressed the responsivenessof T cell 7 days postexposure This immunosuppression wasassociated with the direct effects of SWCNTs on DCs [19]

312 Fullerene As a strong free-radical scavenger [79]fullerene has anti-inflammatory effects The antioxidativeanti-inflammatory activities of novel fullerenes have beenreported [80] Fullerene could suppress Ag-driven type Ihypersensitivity when human MCs and peripheral bloodbasophils were preincubated with C

60fullerenes This sup-

pression involved decreasing the level of reactive oxygenspecies (ROS) [16] In aMC-dependentmodel of anaphylaxisfullerenes prevented the release of histamine [16] In addi-tion polyhydroxylated fullerene derivatives might protectagainst oxidative stress in ischemia-reperfused lungs [81]C60

also suppressed the tumor necrosis factor alpha (TNF-120572) induced production of proinflammatory cytokines in vitroand inhibited the arthritis in vivo [27] Other studies indifferent animalmodels also showed the immunosuppressioneffects of fullerenes For example hydroxylated fullerenescould interfere with the innate immune system in fatheadminnow [31] Nanocrystalline fullerene showed cytotoxicityand promotive effects on tumor cell growth in vitro and invivo respectively which might be due to the suppression ofanticancer immune response of mice by fullerene [14]

313 Gold NPs The anti-inflammatory properties citrate-coatedGNPswere also reported Citrate coatedGNPs (21 nm)did not cause detectable organ or cell toxicity in mice [37]Studies also indicated that citrate-stabilized 5 nm and 15 nmGNPs inhibited cellular responses induced by interleukin 1beta (IL-1120573) and showed anti-inflammatory activity [38]

314 Silver NPs The studies on the immunotoxicity ofAgNPs are very limited AgNPs induced ROS and inflamma-tion [82 83] indicating its potential interference of immunesystem AgNPs (22 nm) exposure caused the downregulationof expression of Malt1 and Sema7a genes which were associ-ated with immune cell function followed by aberrant T celldifferentiation [39]

315 Magnetic NPs Some in vitro studies showed that ironoxide NPs did not induce inflammatory response on humanmonocyte-macrophages [84] and aortic endothelia cells [85]However high doses of iron oxide NPs may induce oxidativestress [86] When treated with PVA-coated SPION humanmonocyte-derived DCs showed a decreased antigen process-ing and CD4 (+) T cell stimulation capacity [87] Thesestudies suggested the potential immune impact of magneticNPs The immunomodulation of the iron oxide NPs wasmuch more complex in vivo Intratracheally administration

of high dose (4 times 500 120583gmouse) and intermediate dose (4 times250 120583gmouse) of iron oxide NPs with a diameter of 35 plusmn14 nm or 147 plusmn 48 nm inhibited the allergic Th2-dominatedresponse induced by ovalbumin (OVA) The low dose (4 times100 120583gmouse) of iron oxide particles (147 plusmn 48 nm) hadno significant effect while the low dose (4 times 100 120583gmouse)of particles (35 plusmn 14 nm) had an adjuvant effect on theTh2 response to OVA [45] A single intratracheal instillation(250 375 or 500120583gmouse) or four-time repeated instillation(500120583gmouse times 4) showed that both NPs induced lunginflammation and decreased pulmonary immune responsesagainst sheep erythrocytes In another study intravenouslyadministration of iron oxide NPs (587 nm) in doses le 10mgironkg shifted the Th1Th2 immunobalance towards theTh2-dominant direction and suppressed the delayed-typehypersensitivity in OVA-sensitized mice [44] Furthermorerepeated instillations resulted in a reduction of inflammationthan single instillation [88]

316 CeO2NPs Due to their reducibility cerium oxide NPs

(nanoceria) were found to have the ability to reduce ROSandmay be used as a novel therapeutic tool for inflammationtreatment [73] Some in vitro studies indicated that nanoceriawith a small diameter caused a significant anti-inflammatoryeffect [73 89 90] For example nanoceria with a diameterof 3ndash5 nm scavenged free radicals inhibited inflammatorymediator production in J774A1 the murine macrophages[73] A recent study reported that the same size of nanoceriainducedAPCs to secrete IL-10 and induced aTh2-dominatedT cell proliferation The nanoceria (5ndash8 nm) showed aneffective antioxidant property in cardiac progenitor cells andprotected the cardiac progenitor cells from H

2O2-induced

cytotoxicity In addition in vivo investigation on immunecells of the sea urchin indicated that nanoceria suppressed theinnate immunity when force-fed 1mL 10minus2 gL 50ndash60 nm ofnanoceria [91]

317 Quantum Dots As efficient energy donors [92] QDscan induce the generation of ROS by transferring energyto nearby oxygen molecules In vitro studies have shownthat QDs induced production of ROS and led to multipleorganelle damage and cell death [93 94] Preexposure toa dose at 10minus7 to 10minus3 120583gmL CdTe QDs suppressed theimmune responses of J774A1 macrophage to bacteria byreducing NO TNF-120572 KCCXCL-1 and IL-8 production[95] These in vitro studies suggested that QDs might havehigh immunotoxicity In vivo studies also showed similarresults CdTe QDs (16 4 and 8mgL for 24 h at 15∘C)significantly decreased the viability of hemocytes as wellas number of hemocytes capable of ingesting fluorescentbeads in Elliption complanata mussels [50] The immuno-suppression was also observed in Juvenile rainbow troutWhen 5 10 and 20 nM CdSCdTe QDs were exposed toJuvenile rainbow trout for 96 h at 15∘C the leukocyte countsviability and both resting and active phagocytic activity weresignificantly reduced [51] QDs affected the proliferation ofimmune cells but did not induce immune response includingcytokine production [96] Size of QDs aggregates may affect

the immune response of QDs Large CdSCdTe QDs aggre-gates (25ndash100 nm) reduced phagocytosis more than smallerNPs (lt25 nm) on bivalves (Mytilus edulis and Elliptio com-planata) and fish (Oncorhynchus mykiss) [97] Thereforecaution is needed to overcome this barrier when QDs areapplied in clinical treatment

318 Polymeric NPs In vivo studies indicated that somepolymeric NPs inhibited inflammation but had no effect onhost immunity [54 98] NPs produced by particle replicationin nonwetting template technology remained in the lungs forup to 7 days without triggering host immunity after intra-tracheal administration of 50 120583gmouse [98] PolystyreneNPs (50 nm) inhibited lung inflammation by intratrachealadministration of 200120583gmouse after allergen challengeThisinhibition was due to the modulation of DCs functions NPsinhibited expansion of CD11c+MHCIIhi DCs in the lungs anddraining lymph node and allergen-laden CD11bhiMHCIIhiDCs in the lungs [54] In addition polystyrene particles havethe potential to halt the disease process in autoimmunityFor example antigen-decorated polystyrene particles with adiameter of 500 nm induced T-cell tolerance and amelioratedexperimental autoimmune encephalomyelitis by inactivatingpathogenic T cells [55]

32 Immunostimulation

321 CarbonNanotubes CNTs induced immunostimulationin vitro and in vivo The oropharyngeal aspiration of MWC-NTs (1 2 and 4mgkg) in C57BL6 mice induced inflam-mation (30 days postinstillation) in lungs [20 21] MWCNTswere translocated progressively into the spleen reached amaximumof 48 h after intraperitoneally (ip) administrationwhich caused the lymphocytic hyperplasia and increasedoxidative stress in the spleen [99] Subcutaneous adminis-tration of MWCNTs with total dose of 10mg for two scinjections in BALBc mice induced acute immunologicalreactions for 1 week (activation of complement and increasedproinflammatory cytokines) However the accumulation ofMWCNTs and injury was not observed in spleen [24]MWC-NTs injected intravenously activated Th2 immune responseby elevating Th2 cytokines and increasing number of CD4+and CD8+ T cell in the spleen [23] In other studies CNTsshowed allergy adjuvant effect in inflammatory mass Forexample SWCNTs andMWCNTs exhibited adjuvant activityto the OVA-sensitized mice [25 100] MWCNTs aggravatedasthma and induced fibrosis in OVA-sensitized lungs butshowed no response with healthy pulmonary The resultsindicated that these NPs could bring harm to asthma patientsbut not health ones [25] In recent in vitro studies MWCNTsincreased the release of a series of cytokines in peripheralblood mononuclear cells (PBMCs) from healthy donorsafter stimulation with toll-like receptor (TLR) agonists orT cell mitogen However MWCNTs suppressed immuneresponses in PBMCs frommite-allergic subjects These stud-ies suggest that MWCNTs may either stimulate or suppressimmune system depending on their immune cell target[101]

322 Graphene GO could induce healthy DCs to differen-tion and maturation at varying degrees [102] but suppressthe antigen-delivering ability of OVA-loaded DCs to Tlymphocytes [103]This inhibitionwas associatedwith down-regulation of subunit LMP7 of immunoproteasome in cellswhich is responsible for antigens processing in DCs [103]Whenmacrophage cells RAW2647 were incubated with GOtoll-like receptor (TLR4TLR9-) 6 modulated autophagy andinflammatory responses occurred [104] In addition PVP-coated GO exhibited lower immunogenicity than GO on theaspect of inducing maturation and differentiation of DCs[102] PVP-coated GO enhanced the physiological activityof macrophages which showed anti-phagocytosis abilityagainst macrophages and delayed the apoptotic process ofT lymphocytes [102] This advantage makes PVP-coated GOa promising candidate of immunoadjuvant The effect oftwo sizes (2120583m and 350 nm) of the GO in response tomicrophages was investigated [105] These two NPs hadequal uptake amount in macrophages but microsized GOinduced stronger inflammation responses and showed diver-gent intracellular locations compared to nanosized GO [105]This result demonstrated that lateral dimension of GO playsan important role in the regulation of cellular responsesRecent studies demonstrated that intravenously deliveredgraphene nanosheets induced site-specificTh2 inflammatoryresponses in the lungs via the IL-33ST2 axis [23] Thiseffect may cause host defense and exacerbation of allergicdiseases However more studies in vivo are needed to assessand eliminate the potential immunomodulation of graphene-based materials to ensure their safety for applications inbiomedicine

323 Fullerene Some studies showed that C60have immun-

ostimulatory properties [28ndash30 103 106] After instillationC60upregulated gene expression of various proinflammatory

cytokines (IL-1 TNF-120572 IL-6) andTh1 cytokines (IL-12 IFN-120574) in mice Besides inflammation C

60could activate the

immune system The carboxyfullerene could prolong theinfiltrating neutrophils to enhance the bactericidal activity ofneutrophils [30] Other studies indicated that fullerene mayenhance the ability of DCs to stimulate T cells and further-more activated cells of innate immune system by enhancingproduction of IL-6 and an activation of natural killer (NK)cells [103 106] In addition immunization of mice with aC60

fullerene derivative conjugated to bovine thyroglobulincould produce a population of fullerene-specific antibodieswhich included a subpopulation that cross-reacted with a C

324 Gold NPs GNPs with different surface modifica-tion showed different immunogenicity in organisms Theimmunogenicity of GNPs coated with C-terminal 19 kDafragment of merozoite surface protein 1 (MSP-1

19) was an

important vaccine candidate In this study GNPs showedpoor immunogenicity in mice but enhanced antibodyresponse when formulated with alum [15] However GNPscoated with monosaccharide or disaccharides could initiatethe immune response by activating the macrophages [107]

BioMed Research International 9

Some studies indicated that high concentrations of PEGcoated on GNPs could induce antibody production andtrigger immune responses High doses of injected PEG-coated GNPs were cleared through these mechanisms [3233]

GNPs can also induce inflammatory responses in vivoWell-dispersed PEG-coated GNPs (13 nm) can be recognizedby host defense mechanism and induce acute inflammationand apoptosis in the liver [34] If inflamed tissues are exposedstronger immune responses may be induced [108] Whenexposed to sensitized mice 40 nm GNPs could lead to athreefold increase in airway hyperreactivity and increase thenumber of neutrophils and macrophages [36]

325 Silver NPs Intratracheal instillation of AgNPs with adiameter of 5225 plusmn 2364 nm could enhance the respiratoryimmune function through oxidative stress and inducedinflammation in the respiratoryWhen alveolar macrophageswere activated by AgNPs to cause phagocytosis the alve-olar macrophages generated ROS and free radicals whichresulted in oxidative stress The normal function of alveolarmacrophages and epithelial cells was subsequently affectedThis led to oversecretion of cytokines and oxides which thencaused the stimulation of the respiratory immune function[40] These opposite results may be due to the differentdiameters of NPs Covalent conjugation of Ag to solid corenanobeads with different diameters ranging from 002 to2 120583m was found localized into DCs (DEC205+ CD40+CD86+) in draining lymph nodes and induced high levels ofIFN-120574 production and high antibody titers in tumor-bearingmice [41]

326 CeO2NPs Instillation of 100 120583g nanoceria with a

diameter of 8 nm in C57BL6 mice revealed that the NPsinduced inflammation in pulmonary system by activatingMCs [46] Other studies using bigger sizes showed the sameeffect Single intratracheal instillation of 20 nm nanoceriaat 015ndash7mgkg caused a dose-dependent inflammation andlung injury [47] The intratracheal instillation of 20ndash30 nmnanoceria (241m2g) with doses of 50 and 150 cm2mouseinduced both acute and chronic neutrophilicmildly cyto-toxic inflammation [48] Inhalation of 55 nm nanoceriawith an average aerosol concentration of 641mgm3 for 4 hinduced cytotoxicity via oxidative stress and led to a chronicinflammatory response including up regulation of IL-1120573TNF-120572 and IL-6 [49]

327 Silica NPs 30 nm amorphous silica NPs were inves-tigated in PBMCs and purified monocytes These NPscould induce inflammatory response as production of IL-1120573 IL-8 and ROS This result indicated the potential ofsilica NPs to evoke innate immune reactions [109] Otherreports showed that 30 and 70 nm silica NPs inducedhigher production of TNF-120572 in RAW2647 cells and strongerinflammatory responses (IL-5uarr IL-6uarr MCP-1uarr keratinocytechemoattractantuarr) than 300 and 1000 nm particles in vivo

through intraperitoneally injection The 70 nm particle-induced TNF-120572 production was dependent on the produc-tion of ROS and activation of mitogen activated proteinkinases (MAPKs) However modification of carboxyl groupson 70 nmparticles dramatically suppressed the inflammatoryresponses [52] As well Kupffer cells stimulated by 15 nmsilica NPs released large amounts of ROS TNF-120572 and NOThe viability of Buffalo rat liver (BRL) cells was reduced aftercultured with silica NP-stimulated Kupffer cells The authorsalso studied the intravenous injections of silica NPs with asingle dose of 50mgkg It caused hepatic inflammation andoxidative stress [53]

328 Polymeric NPs Polymer-based NPs were shown to beeffective adjuvants in vaccination [72 110 111] These poly-mers have the ability to activate cellular immune responsesin the host [112] For example N-trimethyl chitosan-mono-N-carboxymethyl chitosan (TMCMCC) NPs appeared tobe very promising as an adjuvant and delivery system forantigens Intranasal vaccination with tetanus toxoid loadedTMCMCC NPs (2835 plusmn 25 nm) was shown to induceboth the mucosal and systemic immune response (enhancedantibody response) The enhanced immunoglobulin G (IgG)immune response could be explained by the sustained releaseof the toxoid [113]

Some polymer NPs were reported to activate immunesystem through modulating the activation and capabilityof immune cells such as dendritic cells and T cells [114ndash116] Amphiphilic NPs possessed pathogen-mimicking prop-erties by activating DCs similar to lipopolysaccharide (LPS)thus it has the ability to activate innate immune response[114] Poly(methyl vinyl ether-co-maleic anhydride) NPs(149 plusmn 2 nm) activated DCs through TLR stimulation ininnate immune system [115] As well the sulfonate (245 nm)and phosphonate-functionalized (227 nm) polystyrene NPsinduced the maturation of immature DCs and significantlyenhancedT cells stimulatory capacity indicating a shift toTh1response [116]

329 Other NPs Dendrimers have the ability to stimu-late immune system and can be used as potential candi-dates for vaccines [76] Maltose-functionalized dendrimer-peptide complex is a potential DC-based vaccine candi-date by stimulating DC and activating the immune system[117] Research also showed that Pan-DR-binding epitope-derivatized-dendrimer could reduce the effective dose ofliposomal amphotericin B inmurine cutaneous leishmaniasisand enhance adaptive immunity by activating strong parasitespecific T-cell responses [56]

Protein NPs have shown immunostimulating propertiesin recent studies [118ndash120] Self-assembled protein NPs thatdisplayed epitopes of the repeat sequence in circumsporo-zoite protein of plasmodium falciparum (PfCSP) elicited astrong immune response against PfCSP [119 121] In additionprotein NPs mimic viruses have the ability to facilitate DCsactivation and cross-presentationThese proteinNPs codeliv-ered with peptide epitopes to DCs showed an increased andprolonged CD8+ T cell activation [120]

A lipidNPwas investigated in aDNAvaccine applicationThis NP which decorated with stearyl-conjugated KALAan 120572-helical peptide (sequence WEAKLAKALAKALAK-HLAKALAKALKACEA) showed enhancement of transgeneexpression this enhancement was closely related to immune-activation [122] A cationic solid-lipid NP was used as a vac-cine to deliver a DNA vaccine against visceral leishmaniasisHigh levels of IFN-120574 and low levels of IL-10 production weredetected in BALBc mice after administration of the DNAvaccine delivered by this cationic solid-lipid NP This NPinduced a strongTh1 immune response indicating its poten-tial as therapeutic agent against visceral leishmaniasis [57]Nanolipoprotein conjugated with TLR agonists monophos-phoryl lipid A or CpG oligodeoxynucleotides significantlyenhanced the immunostimulatory profiles compared to theagonists alone Moreover the BALBc mice pretreated withCpGnanolipoprotein coloaded nanoconstructs but not CpGalone survived a lethal influenza challenge [58] Researchalso indicated that intravenous injection of liposome-DNAcomplexes elicited production of IFN-120572 and IFN-120573 in vivowhich suggested that the liposome-DNA complexes caninduce inflammation and cause systemic toxicity [123] Inanother study it was reported that Doxil an PEGylatedliposomal formulation of doxorubicin may cause hyper-sensitivity reactions while the standard doxorubicin didnot indicating that liposomes might be responsible for thishypersensitivity [59] It was speculated that the complementsystem activation by Doxil may play a key role in this effect[59]

4 The Factors Affecting Immunomodulationof NPs

Many factors contribute to immunomodulation of NPs Thenature of NPs such as composition surface chemistry sizeshape and protein-binding ability dominates these interac-tions Besides individual difference and exposure route alsocontribute to immunomodulation of NPs

41 Composition Composition of NPs lays a vital role inthe interactions between NPs and immune system Forexample QDs showed high immunotoxicity [50 51] becausethey release heavy metal ions Some other NPs exhibit lessimmunotoxicity [17 23 39 44 54] immunogenic [15 32]or no effect [45] The different core of NPs gave differentreaction in allergy mass For example CNTs and GNPsshowed adjuvant effect and led to hypersensitivity in theseallergy masses [25 26 36] while fullerene often showedimmunosuppression [14 31]

42 Surface Chemistry For NPs with the same compositionsurface properties may also affect the immune system Engi-neered NPs such as CNTs fullerenes GNPs and silica NPscan be modified with diverse surface chemistry This mayalter their immune response both in vitro and in vivo

44 Protein Binding When NPs enter the body throughinjection they firstly interact with blood [129] The plasmaprotein binding on the NPs surface such as apolipoprotein Eand transferrinmay contribute to the activationdeactivationof receptor-dependent signaling [130]

The amount and types of proteins adsorbed on the NPsaffect the interactions of cells and NPs and the biologicalresponses [131 132]The composition surface characteristicsand shape of NPs affect the manners that the proteinsbind to them [129 133ndash136] The blood proteins adsorbedonto the NPs include immunoglobulins apolipoproteins andproteins of the complement system among many othersThese proteins may act as signals for immune responses [137138] Furthermore NPs may induce conformational changesin the structure of adsorbed proteins Negatively chargedpoly(acrylic acid-) conjugated GNPs bound with fibrinogenand induced the unfolding of this protein which promotedinteraction with Mac-1 an integrin receptor This activationincreased the NF-120581B signalling pathway and released inflam-matory cytokines [139]

45 Exposure Route Exposure route is another factor affect-ing the immunomodulation ofNPsTheoutcomes of immuneresponse are dependent on entrance of NPs In the lungsDCs pulmonary epithelium and macrophages play animportant role in handling foreign materials In the bloodleukocyte such as neutrophil eosinophil basophil lympho-cyte and monocyte play a vital role Single intratrachealinstillation of 500120583gmouse iron oxide NPs (35 plusmn 14 nmand 147 plusmn 48 nm) induced lung inflammation and decreasedpulmonary immune responses against sheep erythrocytes[88] Pharyngeal aspiration of SWCNTs modified systemicimmunity by modulating DCs function [19] Intravenouslyadministration of iron oxide NPs (587 nm) could sup-press the infiltration and functional activity of Th1 cellsand macrophages [44] Intravenous injection of graphenenanosheets activated a Th2 immune response which con-sisted of neutrophilic influx and a significant increase inIL-5 IL-13 IL-33 in the bronchoalvelar lavage fluid [23]The dosage of administration is also important Intratrachealinjection of iron oxide NPs (35 plusmn 14 nm) inhibited theallergic response in OVA-sensitized mice at a dosage of 4 times250120583gmouse or 4 times 500 120583gmouse but showed adjuvanteffect at a dosage of 4 times 100 120583gmouse [45]

5 The Mechanisms of ImmunomodulationInduced by NPs

NPs interact with both innate and adaptive immune cellsaffect their functions and disturb immune system (Figure 3)

Inflammation is an important response of immune sys-tem which can be induced by NPs evidenced by the pro-duction of cytokines or chemokines Oxidative stress causedby NPs is reported to be the main downstream events ofthe inflammation NPs have large surface areas and strong

oxidative abilities than normal particles [140] Oxidativedamage induced by NPs is an important factor of immuneimbalance [11] Many types of NPs have been shown toproduce ROS in vitro and in vivo and enhance immunefunction or inflammatory response [40 49 53 86 141] Freeradical-induced tissue damage plays an important role ininflammatory diseases [142 143]

The signal pathway to induce ROS and mediate inflam-mation was reported Among them TLR4 signaling pathwaywas documented GO could induce intracellular ROS whichdecreased the viability of macrophages and induced necrosisby a TLR4 signaling pathway (Figure 4) [144] TLR is areceptor of the innate immune system and innate immunitycould be triggered by stimulating TLRs and lead to strongadaptive immunity [115] Activation of the TLR pathwayscould induce chronic inflammation and ROS [145] Resentresearch indicated that quantum dots could activate myeloiddifferentiation primary response gene 88 (MyD88 which isan adapter protein to activate NF-120581B) dependent-TLRs inmcrophages and activated NF-120581B [146]

NF-120581B pathway is another key regulator of immuneresponse [125 147ndash149] As an important regulator of proin-flammatory gene expression synthesis of cytokines suchas IL-1120573 IL-6 IL-8 and TNF-120572 is mediated by NF-120581B

Activation of NF-120581B may induce human inflammatory dis-eases [150 151] It was reported that negatively chargedpoly(acrylic acid-) conjugated GNP activated the NF-120581Bsignalling pathway in THP-1 cells The cells released inflam-matory cytokines including TNF-120572 and IL-8 [139] Andcitrate-stabilized 10 nm GNPs could induce activation of anNF-120581B regulated luciferase reporter in murine B-lymphocytecell line (CH12LX) and altered the cell function [152]

NPs may also disturb the immune balance by inappro-priate maturationactivation of APCs such as DCs [26 153]Intratracheal instillation of 43 nmMIONs the alveolar regionof BALBc mice could generate a significant number ofexosomes These exosomes were quickly eliminated from thealveolar region into systemic circulation and transferred theirsignals to the immune system which resulted in maturationof DCs and activation of splenic T cells and the exosome-induced T-cell activation is more efficient in OVA-sensitizedmice [42 43] Cytotoxicity to immune cells may contribute toimmunosuppression of NPs QDs may decrease the viabilityof hemocytes in Elliption complanata mussels [50] andreduced phagocytosis on bivalves and fish [97]

Recent reports indicated that NPs could modulate thehomeostasis of immune cells including the shift of Th1Th2balance [43 44 89] and monocyte homeostasis [154] Forexample magnetic iron oxide NPs activated the T cellsinduced a Th1 polarization and aggravated inflammation[43]Other studies showed that SWCNTs accentuatedThcellsimmunity includingTh2 (IL-4uarr IL-5uarr and IL-13uarr) andTh17

(IL-17Auarr IL-23uarr) The inappropriate maturationactivationof APCs such as DCs might be responsible for these accen-tuated Th cells immunity [26 153] The normal immunesystem keeps a Th1Th2 balance in order to achieve anappropriate immune response Selectively activating Th1 orTh2 cells results in immune deviation and breaks the balanceof immune system In addition MWCNTs could selectivelydecrease phagocytosis-competent monocytes and promoteadhesion of the phagocytosis-incompetent monocytes inblood flow [154]

6 Conclusion

The immune response of NPs is like a double-edged swordin nanomedicine applications by bringing both benefits andharms We should take advantage of the benefits from theimmunomodulating properties of NPs and on the otherhand avoid the undesirable immune responses in order tominimize the systemic side effects The factors affecting theimmune response are complex including particle compo-sition size surface chemistry plasma protein binding andexposure route Investigation of the relationship betweenproperties of NPs and systemic immune response is crucialfor their application in medicine and other areas Althoughtreatments of acute and long-term immune toxicities havebeen developed current approaches of prediction preven-tion and treatment of nanoimmunomodulation are stilllacking encouraging further in-depth studies

(reduced T-cell-dependent antibody against sheep erythro-cytes and T-cell proliferative ability and decreased naturalkiller cell activity) This suppression was accompanied byincreased spleen gene expression of interleukin-10 (IL-10)which is an anti-inflammatory cytokine and NAD(P)H oxi-doreductase [17] Other studies showed that pharyngeal aspi-ration of SWCNTs (40 120583gmouse) in BALBc mice inducedpulmonary inflammation and suppressed the responsivenessof T cell 7 days postexposure This immunosuppression wasassociated with the direct effects of SWCNTs on DCs [19]

312 Fullerene As a strong free-radical scavenger [79]fullerene has anti-inflammatory effects The antioxidativeanti-inflammatory activities of novel fullerenes have beenreported [80] Fullerene could suppress Ag-driven type Ihypersensitivity when human MCs and peripheral bloodbasophils were preincubated with C

60fullerenes This sup-

pression involved decreasing the level of reactive oxygenspecies (ROS) [16] In aMC-dependentmodel of anaphylaxisfullerenes prevented the release of histamine [16] In addi-tion polyhydroxylated fullerene derivatives might protectagainst oxidative stress in ischemia-reperfused lungs [81]C60

also suppressed the tumor necrosis factor alpha (TNF-120572) induced production of proinflammatory cytokines in vitroand inhibited the arthritis in vivo [27] Other studies indifferent animalmodels also showed the immunosuppressioneffects of fullerenes For example hydroxylated fullerenescould interfere with the innate immune system in fatheadminnow [31] Nanocrystalline fullerene showed cytotoxicityand promotive effects on tumor cell growth in vitro and invivo respectively which might be due to the suppression ofanticancer immune response of mice by fullerene [14]

313 Gold NPs The anti-inflammatory properties citrate-coatedGNPswere also reported Citrate coatedGNPs (21 nm)did not cause detectable organ or cell toxicity in mice [37]Studies also indicated that citrate-stabilized 5 nm and 15 nmGNPs inhibited cellular responses induced by interleukin 1beta (IL-1120573) and showed anti-inflammatory activity [38]

314 Silver NPs The studies on the immunotoxicity ofAgNPs are very limited AgNPs induced ROS and inflamma-tion [82 83] indicating its potential interference of immunesystem AgNPs (22 nm) exposure caused the downregulationof expression of Malt1 and Sema7a genes which were associ-ated with immune cell function followed by aberrant T celldifferentiation [39]

315 Magnetic NPs Some in vitro studies showed that ironoxide NPs did not induce inflammatory response on humanmonocyte-macrophages [84] and aortic endothelia cells [85]However high doses of iron oxide NPs may induce oxidativestress [86] When treated with PVA-coated SPION humanmonocyte-derived DCs showed a decreased antigen process-ing and CD4 (+) T cell stimulation capacity [87] Thesestudies suggested the potential immune impact of magneticNPs The immunomodulation of the iron oxide NPs wasmuch more complex in vivo Intratracheally administration

of high dose (4 times 500 120583gmouse) and intermediate dose (4 times250 120583gmouse) of iron oxide NPs with a diameter of 35 plusmn14 nm or 147 plusmn 48 nm inhibited the allergic Th2-dominatedresponse induced by ovalbumin (OVA) The low dose (4 times100 120583gmouse) of iron oxide particles (147 plusmn 48 nm) hadno significant effect while the low dose (4 times 100 120583gmouse)of particles (35 plusmn 14 nm) had an adjuvant effect on theTh2 response to OVA [45] A single intratracheal instillation(250 375 or 500120583gmouse) or four-time repeated instillation(500120583gmouse times 4) showed that both NPs induced lunginflammation and decreased pulmonary immune responsesagainst sheep erythrocytes In another study intravenouslyadministration of iron oxide NPs (587 nm) in doses le 10mgironkg shifted the Th1Th2 immunobalance towards theTh2-dominant direction and suppressed the delayed-typehypersensitivity in OVA-sensitized mice [44] Furthermorerepeated instillations resulted in a reduction of inflammationthan single instillation [88]

316 CeO2NPs Due to their reducibility cerium oxide NPs

(nanoceria) were found to have the ability to reduce ROSandmay be used as a novel therapeutic tool for inflammationtreatment [73] Some in vitro studies indicated that nanoceriawith a small diameter caused a significant anti-inflammatoryeffect [73 89 90] For example nanoceria with a diameterof 3ndash5 nm scavenged free radicals inhibited inflammatorymediator production in J774A1 the murine macrophages[73] A recent study reported that the same size of nanoceriainducedAPCs to secrete IL-10 and induced aTh2-dominatedT cell proliferation The nanoceria (5ndash8 nm) showed aneffective antioxidant property in cardiac progenitor cells andprotected the cardiac progenitor cells from H

2O2-induced

cytotoxicity In addition in vivo investigation on immunecells of the sea urchin indicated that nanoceria suppressed theinnate immunity when force-fed 1mL 10minus2 gL 50ndash60 nm ofnanoceria [91]

317 Quantum Dots As efficient energy donors [92] QDscan induce the generation of ROS by transferring energyto nearby oxygen molecules In vitro studies have shownthat QDs induced production of ROS and led to multipleorganelle damage and cell death [93 94] Preexposure toa dose at 10minus7 to 10minus3 120583gmL CdTe QDs suppressed theimmune responses of J774A1 macrophage to bacteria byreducing NO TNF-120572 KCCXCL-1 and IL-8 production[95] These in vitro studies suggested that QDs might havehigh immunotoxicity In vivo studies also showed similarresults CdTe QDs (16 4 and 8mgL for 24 h at 15∘C)significantly decreased the viability of hemocytes as wellas number of hemocytes capable of ingesting fluorescentbeads in Elliption complanata mussels [50] The immuno-suppression was also observed in Juvenile rainbow troutWhen 5 10 and 20 nM CdSCdTe QDs were exposed toJuvenile rainbow trout for 96 h at 15∘C the leukocyte countsviability and both resting and active phagocytic activity weresignificantly reduced [51] QDs affected the proliferation ofimmune cells but did not induce immune response includingcytokine production [96] Size of QDs aggregates may affect

the immune response of QDs Large CdSCdTe QDs aggre-gates (25ndash100 nm) reduced phagocytosis more than smallerNPs (lt25 nm) on bivalves (Mytilus edulis and Elliptio com-planata) and fish (Oncorhynchus mykiss) [97] Thereforecaution is needed to overcome this barrier when QDs areapplied in clinical treatment

318 Polymeric NPs In vivo studies indicated that somepolymeric NPs inhibited inflammation but had no effect onhost immunity [54 98] NPs produced by particle replicationin nonwetting template technology remained in the lungs forup to 7 days without triggering host immunity after intra-tracheal administration of 50 120583gmouse [98] PolystyreneNPs (50 nm) inhibited lung inflammation by intratrachealadministration of 200120583gmouse after allergen challengeThisinhibition was due to the modulation of DCs functions NPsinhibited expansion of CD11c+MHCIIhi DCs in the lungs anddraining lymph node and allergen-laden CD11bhiMHCIIhiDCs in the lungs [54] In addition polystyrene particles havethe potential to halt the disease process in autoimmunityFor example antigen-decorated polystyrene particles with adiameter of 500 nm induced T-cell tolerance and amelioratedexperimental autoimmune encephalomyelitis by inactivatingpathogenic T cells [55]

32 Immunostimulation

321 CarbonNanotubes CNTs induced immunostimulationin vitro and in vivo The oropharyngeal aspiration of MWC-NTs (1 2 and 4mgkg) in C57BL6 mice induced inflam-mation (30 days postinstillation) in lungs [20 21] MWCNTswere translocated progressively into the spleen reached amaximumof 48 h after intraperitoneally (ip) administrationwhich caused the lymphocytic hyperplasia and increasedoxidative stress in the spleen [99] Subcutaneous adminis-tration of MWCNTs with total dose of 10mg for two scinjections in BALBc mice induced acute immunologicalreactions for 1 week (activation of complement and increasedproinflammatory cytokines) However the accumulation ofMWCNTs and injury was not observed in spleen [24]MWC-NTs injected intravenously activated Th2 immune responseby elevating Th2 cytokines and increasing number of CD4+and CD8+ T cell in the spleen [23] In other studies CNTsshowed allergy adjuvant effect in inflammatory mass Forexample SWCNTs andMWCNTs exhibited adjuvant activityto the OVA-sensitized mice [25 100] MWCNTs aggravatedasthma and induced fibrosis in OVA-sensitized lungs butshowed no response with healthy pulmonary The resultsindicated that these NPs could bring harm to asthma patientsbut not health ones [25] In recent in vitro studies MWCNTsincreased the release of a series of cytokines in peripheralblood mononuclear cells (PBMCs) from healthy donorsafter stimulation with toll-like receptor (TLR) agonists orT cell mitogen However MWCNTs suppressed immuneresponses in PBMCs frommite-allergic subjects These stud-ies suggest that MWCNTs may either stimulate or suppressimmune system depending on their immune cell target[101]

322 Graphene GO could induce healthy DCs to differen-tion and maturation at varying degrees [102] but suppressthe antigen-delivering ability of OVA-loaded DCs to Tlymphocytes [103]This inhibitionwas associatedwith down-regulation of subunit LMP7 of immunoproteasome in cellswhich is responsible for antigens processing in DCs [103]Whenmacrophage cells RAW2647 were incubated with GOtoll-like receptor (TLR4TLR9-) 6 modulated autophagy andinflammatory responses occurred [104] In addition PVP-coated GO exhibited lower immunogenicity than GO on theaspect of inducing maturation and differentiation of DCs[102] PVP-coated GO enhanced the physiological activityof macrophages which showed anti-phagocytosis abilityagainst macrophages and delayed the apoptotic process ofT lymphocytes [102] This advantage makes PVP-coated GOa promising candidate of immunoadjuvant The effect oftwo sizes (2120583m and 350 nm) of the GO in response tomicrophages was investigated [105] These two NPs hadequal uptake amount in macrophages but microsized GOinduced stronger inflammation responses and showed diver-gent intracellular locations compared to nanosized GO [105]This result demonstrated that lateral dimension of GO playsan important role in the regulation of cellular responsesRecent studies demonstrated that intravenously deliveredgraphene nanosheets induced site-specificTh2 inflammatoryresponses in the lungs via the IL-33ST2 axis [23] Thiseffect may cause host defense and exacerbation of allergicdiseases However more studies in vivo are needed to assessand eliminate the potential immunomodulation of graphene-based materials to ensure their safety for applications inbiomedicine

323 Fullerene Some studies showed that C60have immun-

ostimulatory properties [28ndash30 103 106] After instillationC60upregulated gene expression of various proinflammatory

cytokines (IL-1 TNF-120572 IL-6) andTh1 cytokines (IL-12 IFN-120574) in mice Besides inflammation C

60could activate the

immune system The carboxyfullerene could prolong theinfiltrating neutrophils to enhance the bactericidal activity ofneutrophils [30] Other studies indicated that fullerene mayenhance the ability of DCs to stimulate T cells and further-more activated cells of innate immune system by enhancingproduction of IL-6 and an activation of natural killer (NK)cells [103 106] In addition immunization of mice with aC60

fullerene derivative conjugated to bovine thyroglobulincould produce a population of fullerene-specific antibodieswhich included a subpopulation that cross-reacted with a C

fullerene [29]

324 Gold NPs GNPs with different surface modifica-tion showed different immunogenicity in organisms Theimmunogenicity of GNPs coated with C-terminal 19 kDafragment of merozoite surface protein 1 (MSP-1

19) was an

important vaccine candidate In this study GNPs showedpoor immunogenicity in mice but enhanced antibodyresponse when formulated with alum [15] However GNPscoated with monosaccharide or disaccharides could initiatethe immune response by activating the macrophages [107]

BioMed Research International 9

Some studies indicated that high concentrations of PEGcoated on GNPs could induce antibody production andtrigger immune responses High doses of injected PEG-coated GNPs were cleared through these mechanisms [3233]

GNPs can also induce inflammatory responses in vivoWell-dispersed PEG-coated GNPs (13 nm) can be recognizedby host defense mechanism and induce acute inflammationand apoptosis in the liver [34] If inflamed tissues are exposedstronger immune responses may be induced [108] Whenexposed to sensitized mice 40 nm GNPs could lead to athreefold increase in airway hyperreactivity and increase thenumber of neutrophils and macrophages [36]

325 Silver NPs Intratracheal instillation of AgNPs with adiameter of 5225 plusmn 2364 nm could enhance the respiratoryimmune function through oxidative stress and inducedinflammation in the respiratoryWhen alveolar macrophageswere activated by AgNPs to cause phagocytosis the alve-olar macrophages generated ROS and free radicals whichresulted in oxidative stress The normal function of alveolarmacrophages and epithelial cells was subsequently affectedThis led to oversecretion of cytokines and oxides which thencaused the stimulation of the respiratory immune function[40] These opposite results may be due to the differentdiameters of NPs Covalent conjugation of Ag to solid corenanobeads with different diameters ranging from 002 to2 120583m was found localized into DCs (DEC205+ CD40+CD86+) in draining lymph nodes and induced high levels ofIFN-120574 production and high antibody titers in tumor-bearingmice [41]

326 CeO2NPs Instillation of 100 120583g nanoceria with a

diameter of 8 nm in C57BL6 mice revealed that the NPsinduced inflammation in pulmonary system by activatingMCs [46] Other studies using bigger sizes showed the sameeffect Single intratracheal instillation of 20 nm nanoceriaat 015ndash7mgkg caused a dose-dependent inflammation andlung injury [47] The intratracheal instillation of 20ndash30 nmnanoceria (241m2g) with doses of 50 and 150 cm2mouseinduced both acute and chronic neutrophilicmildly cyto-toxic inflammation [48] Inhalation of 55 nm nanoceriawith an average aerosol concentration of 641mgm3 for 4 hinduced cytotoxicity via oxidative stress and led to a chronicinflammatory response including up regulation of IL-1120573TNF-120572 and IL-6 [49]

327 Silica NPs 30 nm amorphous silica NPs were inves-tigated in PBMCs and purified monocytes These NPscould induce inflammatory response as production of IL-1120573 IL-8 and ROS This result indicated the potential ofsilica NPs to evoke innate immune reactions [109] Otherreports showed that 30 and 70 nm silica NPs inducedhigher production of TNF-120572 in RAW2647 cells and strongerinflammatory responses (IL-5uarr IL-6uarr MCP-1uarr keratinocytechemoattractantuarr) than 300 and 1000 nm particles in vivo

through intraperitoneally injection The 70 nm particle-induced TNF-120572 production was dependent on the produc-tion of ROS and activation of mitogen activated proteinkinases (MAPKs) However modification of carboxyl groupson 70 nmparticles dramatically suppressed the inflammatoryresponses [52] As well Kupffer cells stimulated by 15 nmsilica NPs released large amounts of ROS TNF-120572 and NOThe viability of Buffalo rat liver (BRL) cells was reduced aftercultured with silica NP-stimulated Kupffer cells The authorsalso studied the intravenous injections of silica NPs with asingle dose of 50mgkg It caused hepatic inflammation andoxidative stress [53]

328 Polymeric NPs Polymer-based NPs were shown to beeffective adjuvants in vaccination [72 110 111] These poly-mers have the ability to activate cellular immune responsesin the host [112] For example N-trimethyl chitosan-mono-N-carboxymethyl chitosan (TMCMCC) NPs appeared tobe very promising as an adjuvant and delivery system forantigens Intranasal vaccination with tetanus toxoid loadedTMCMCC NPs (2835 plusmn 25 nm) was shown to induceboth the mucosal and systemic immune response (enhancedantibody response) The enhanced immunoglobulin G (IgG)immune response could be explained by the sustained releaseof the toxoid [113]

Some polymer NPs were reported to activate immunesystem through modulating the activation and capabilityof immune cells such as dendritic cells and T cells [114ndash116] Amphiphilic NPs possessed pathogen-mimicking prop-erties by activating DCs similar to lipopolysaccharide (LPS)thus it has the ability to activate innate immune response[114] Poly(methyl vinyl ether-co-maleic anhydride) NPs(149 plusmn 2 nm) activated DCs through TLR stimulation ininnate immune system [115] As well the sulfonate (245 nm)and phosphonate-functionalized (227 nm) polystyrene NPsinduced the maturation of immature DCs and significantlyenhancedT cells stimulatory capacity indicating a shift toTh1response [116]

329 Other NPs Dendrimers have the ability to stimu-late immune system and can be used as potential candi-dates for vaccines [76] Maltose-functionalized dendrimer-peptide complex is a potential DC-based vaccine candi-date by stimulating DC and activating the immune system[117] Research also showed that Pan-DR-binding epitope-derivatized-dendrimer could reduce the effective dose ofliposomal amphotericin B inmurine cutaneous leishmaniasisand enhance adaptive immunity by activating strong parasitespecific T-cell responses [56]

Protein NPs have shown immunostimulating propertiesin recent studies [118ndash120] Self-assembled protein NPs thatdisplayed epitopes of the repeat sequence in circumsporo-zoite protein of plasmodium falciparum (PfCSP) elicited astrong immune response against PfCSP [119 121] In additionprotein NPs mimic viruses have the ability to facilitate DCsactivation and cross-presentationThese proteinNPs codeliv-ered with peptide epitopes to DCs showed an increased andprolonged CD8+ T cell activation [120]

A lipidNPwas investigated in aDNAvaccine applicationThis NP which decorated with stearyl-conjugated KALAan 120572-helical peptide (sequence WEAKLAKALAKALAK-HLAKALAKALKACEA) showed enhancement of transgeneexpression this enhancement was closely related to immune-activation [122] A cationic solid-lipid NP was used as a vac-cine to deliver a DNA vaccine against visceral leishmaniasisHigh levels of IFN-120574 and low levels of IL-10 production weredetected in BALBc mice after administration of the DNAvaccine delivered by this cationic solid-lipid NP This NPinduced a strongTh1 immune response indicating its poten-tial as therapeutic agent against visceral leishmaniasis [57]Nanolipoprotein conjugated with TLR agonists monophos-phoryl lipid A or CpG oligodeoxynucleotides significantlyenhanced the immunostimulatory profiles compared to theagonists alone Moreover the BALBc mice pretreated withCpGnanolipoprotein coloaded nanoconstructs but not CpGalone survived a lethal influenza challenge [58] Researchalso indicated that intravenous injection of liposome-DNAcomplexes elicited production of IFN-120572 and IFN-120573 in vivowhich suggested that the liposome-DNA complexes caninduce inflammation and cause systemic toxicity [123] Inanother study it was reported that Doxil an PEGylatedliposomal formulation of doxorubicin may cause hyper-sensitivity reactions while the standard doxorubicin didnot indicating that liposomes might be responsible for thishypersensitivity [59] It was speculated that the complementsystem activation by Doxil may play a key role in this effect[59]

4 The Factors Affecting Immunomodulationof NPs

Many factors contribute to immunomodulation of NPs Thenature of NPs such as composition surface chemistry sizeshape and protein-binding ability dominates these interac-tions Besides individual difference and exposure route alsocontribute to immunomodulation of NPs

41 Composition Composition of NPs lays a vital role inthe interactions between NPs and immune system Forexample QDs showed high immunotoxicity [50 51] becausethey release heavy metal ions Some other NPs exhibit lessimmunotoxicity [17 23 39 44 54] immunogenic [15 32]or no effect [45] The different core of NPs gave differentreaction in allergy mass For example CNTs and GNPsshowed adjuvant effect and led to hypersensitivity in theseallergy masses [25 26 36] while fullerene often showedimmunosuppression [14 31]

42 Surface Chemistry For NPs with the same compositionsurface properties may also affect the immune system Engi-neered NPs such as CNTs fullerenes GNPs and silica NPscan be modified with diverse surface chemistry This mayalter their immune response both in vitro and in vivo

Eighty diversely functionalized multiwall nanotube(MWNT) induced different levels of protein bindingcytotoxicity and immune responses (Figure 2) [124] The

modification of MWCNTs significantly alleviated nuclearfactor kappa B (NF-120581B) activation and reduced immuno-toxicity ofMWCNTs in BALBcmice [125] Carboxyfullereneactivated immune system of C57BL6 mice by prolongingthe infiltrating neutrophils to enhance the bactericidalactivity of neutrophils [30] while hydroxylated fullerenesinterferedwith the innate immune system in fatheadminnow[31] MWCNTs-PEG induced less generation of ROS andcytotoxicity in macrophages than MWCNTs-COOH whichwas in correspondence with the lower cellular uptake ofMWCNTs-PEG [126] The monolayer-protected GNPs invivo were studied Simple place-exchange reactions withinthe monolayer by short chain mercaptotetraethylene glycolhave been used The short chain at lower concentrations didnot trigger the immune system to produce anti-PEG antibody[33] However high concentration mixed monolayer coatedNPs initiated an immune response [32] Silica NPs (70 nm)induced strong inflammation by intraperitoneal injectionbut these inflammatory responses could be dramaticallysuppressed by surface modification by carboxyl groups [52]The toxicity of porous silica NPs to immune cells was surfacechemistry and surface charge-dependent Compare tosurface hydrophobicity surface charge had stronger impacton NPsrsquo immunotoxicity in vitro and in vivo Positivelycharged hydrophobic NPs showed more DNA damage thannegatively charged hydrophilic NPs [127]

43 Size Size is another important parameter that deter-mines the interaction with organisms When examinedimmunity is induced by a series of differentially sized (2040 49 67 93 101 and 123 nm) polystyrene nanobeads IFN-120574 induction from CD8+ T cells was limited to 40 and 49 nmbeads while 93ndash123 nmbeads inducedCD4+ T cell activationand increased IL-4 levelThese results showed that the size ofnanobead for vaccination could influence the type 1type 2cytokine balance This would be useful in the developmentof vaccines against common human pathogens [128] 200 nmNPs increased more antigen-specific polyfunctional CD4+ Tcells as compared to 30 nm NPs The immunoactivity of dis-accharides coated GNPs is strongly dependent on size Theyused 2 and 5 nm GNPs coated with disaccharides These NPsactivated the macrophages and induced the proliferation of Tcells and the increase of IL-2 levels The 5 nmNPs performedfar better than 2 nmones (increasedAPC proliferationMHCII expression T cell proliferation and IL-2 expression) [107]Other researches indicated that single instillation (250 375or 500 120583gmouse) of 35 plusmn 14 nm iron oxide NPs inducedhigher levels of inflammation and immunodepression than147plusmn48 nm ones [88] Repeated intratracheal administrationof high dose (4 times 500120583gmouse) and intermediate dose (4 times250 120583gmouse) of the same NPs inhibited the allergic Th2-dominated response induced by OVA The low dose (4 times100 120583gmouse) of 147 plusmn 48 nm iron oxide particles had nosignificant effect but the low dose (4 times 100 120583gmouse) of 35plusmn14 nm particles had an adjuvant effect on theTh2 response toOVA [45] Aggregate size may also affect the immunotoxicityof QDs The toxicity of CdSCdTe QDs was size dependentLarge CdSCdTe QD aggregates (25 nmndash100 nm) reduced

44 Protein Binding When NPs enter the body throughinjection they firstly interact with blood [129] The plasmaprotein binding on the NPs surface such as apolipoprotein Eand transferrinmay contribute to the activationdeactivationof receptor-dependent signaling [130]

The amount and types of proteins adsorbed on the NPsaffect the interactions of cells and NPs and the biologicalresponses [131 132]The composition surface characteristicsand shape of NPs affect the manners that the proteinsbind to them [129 133ndash136] The blood proteins adsorbedonto the NPs include immunoglobulins apolipoproteins andproteins of the complement system among many othersThese proteins may act as signals for immune responses [137138] Furthermore NPs may induce conformational changesin the structure of adsorbed proteins Negatively chargedpoly(acrylic acid-) conjugated GNPs bound with fibrinogenand induced the unfolding of this protein which promotedinteraction with Mac-1 an integrin receptor This activationincreased the NF-120581B signalling pathway and released inflam-matory cytokines [139]

45 Exposure Route Exposure route is another factor affect-ing the immunomodulation ofNPsTheoutcomes of immuneresponse are dependent on entrance of NPs In the lungsDCs pulmonary epithelium and macrophages play animportant role in handling foreign materials In the bloodleukocyte such as neutrophil eosinophil basophil lympho-cyte and monocyte play a vital role Single intratrachealinstillation of 500120583gmouse iron oxide NPs (35 plusmn 14 nmand 147 plusmn 48 nm) induced lung inflammation and decreasedpulmonary immune responses against sheep erythrocytes[88] Pharyngeal aspiration of SWCNTs modified systemicimmunity by modulating DCs function [19] Intravenouslyadministration of iron oxide NPs (587 nm) could sup-press the infiltration and functional activity of Th1 cellsand macrophages [44] Intravenous injection of graphenenanosheets activated a Th2 immune response which con-sisted of neutrophilic influx and a significant increase inIL-5 IL-13 IL-33 in the bronchoalvelar lavage fluid [23]The dosage of administration is also important Intratrachealinjection of iron oxide NPs (35 plusmn 14 nm) inhibited theallergic response in OVA-sensitized mice at a dosage of 4 times250120583gmouse or 4 times 500 120583gmouse but showed adjuvanteffect at a dosage of 4 times 100 120583gmouse [45]

5 The Mechanisms of ImmunomodulationInduced by NPs

NPs interact with both innate and adaptive immune cellsaffect their functions and disturb immune system (Figure 3)

Inflammation is an important response of immune sys-tem which can be induced by NPs evidenced by the pro-duction of cytokines or chemokines Oxidative stress causedby NPs is reported to be the main downstream events ofthe inflammation NPs have large surface areas and strong

oxidative abilities than normal particles [140] Oxidativedamage induced by NPs is an important factor of immuneimbalance [11] Many types of NPs have been shown toproduce ROS in vitro and in vivo and enhance immunefunction or inflammatory response [40 49 53 86 141] Freeradical-induced tissue damage plays an important role ininflammatory diseases [142 143]

The signal pathway to induce ROS and mediate inflam-mation was reported Among them TLR4 signaling pathwaywas documented GO could induce intracellular ROS whichdecreased the viability of macrophages and induced necrosisby a TLR4 signaling pathway (Figure 4) [144] TLR is areceptor of the innate immune system and innate immunitycould be triggered by stimulating TLRs and lead to strongadaptive immunity [115] Activation of the TLR pathwayscould induce chronic inflammation and ROS [145] Resentresearch indicated that quantum dots could activate myeloiddifferentiation primary response gene 88 (MyD88 which isan adapter protein to activate NF-120581B) dependent-TLRs inmcrophages and activated NF-120581B [146]

NF-120581B pathway is another key regulator of immuneresponse [125 147ndash149] As an important regulator of proin-flammatory gene expression synthesis of cytokines suchas IL-1120573 IL-6 IL-8 and TNF-120572 is mediated by NF-120581B

Activation of NF-120581B may induce human inflammatory dis-eases [150 151] It was reported that negatively chargedpoly(acrylic acid-) conjugated GNP activated the NF-120581Bsignalling pathway in THP-1 cells The cells released inflam-matory cytokines including TNF-120572 and IL-8 [139] Andcitrate-stabilized 10 nm GNPs could induce activation of anNF-120581B regulated luciferase reporter in murine B-lymphocytecell line (CH12LX) and altered the cell function [152]

NPs may also disturb the immune balance by inappro-priate maturationactivation of APCs such as DCs [26 153]Intratracheal instillation of 43 nmMIONs the alveolar regionof BALBc mice could generate a significant number ofexosomes These exosomes were quickly eliminated from thealveolar region into systemic circulation and transferred theirsignals to the immune system which resulted in maturationof DCs and activation of splenic T cells and the exosome-induced T-cell activation is more efficient in OVA-sensitizedmice [42 43] Cytotoxicity to immune cells may contribute toimmunosuppression of NPs QDs may decrease the viabilityof hemocytes in Elliption complanata mussels [50] andreduced phagocytosis on bivalves and fish [97]

Recent reports indicated that NPs could modulate thehomeostasis of immune cells including the shift of Th1Th2balance [43 44 89] and monocyte homeostasis [154] Forexample magnetic iron oxide NPs activated the T cellsinduced a Th1 polarization and aggravated inflammation[43]Other studies showed that SWCNTs accentuatedThcellsimmunity includingTh2 (IL-4uarr IL-5uarr and IL-13uarr) andTh17

(IL-17Auarr IL-23uarr) The inappropriate maturationactivationof APCs such as DCs might be responsible for these accen-tuated Th cells immunity [26 153] The normal immunesystem keeps a Th1Th2 balance in order to achieve anappropriate immune response Selectively activating Th1 orTh2 cells results in immune deviation and breaks the balanceof immune system In addition MWCNTs could selectivelydecrease phagocytosis-competent monocytes and promoteadhesion of the phagocytosis-incompetent monocytes inblood flow [154]

6 Conclusion

The immune response of NPs is like a double-edged swordin nanomedicine applications by bringing both benefits andharms We should take advantage of the benefits from theimmunomodulating properties of NPs and on the otherhand avoid the undesirable immune responses in order tominimize the systemic side effects The factors affecting theimmune response are complex including particle compo-sition size surface chemistry plasma protein binding andexposure route Investigation of the relationship betweenproperties of NPs and systemic immune response is crucialfor their application in medicine and other areas Althoughtreatments of acute and long-term immune toxicities havebeen developed current approaches of prediction preven-tion and treatment of nanoimmunomodulation are stilllacking encouraging further in-depth studies

(reduced T-cell-dependent antibody against sheep erythro-cytes and T-cell proliferative ability and decreased naturalkiller cell activity) This suppression was accompanied byincreased spleen gene expression of interleukin-10 (IL-10)which is an anti-inflammatory cytokine and NAD(P)H oxi-doreductase [17] Other studies showed that pharyngeal aspi-ration of SWCNTs (40 120583gmouse) in BALBc mice inducedpulmonary inflammation and suppressed the responsivenessof T cell 7 days postexposure This immunosuppression wasassociated with the direct effects of SWCNTs on DCs [19]

312 Fullerene As a strong free-radical scavenger [79]fullerene has anti-inflammatory effects The antioxidativeanti-inflammatory activities of novel fullerenes have beenreported [80] Fullerene could suppress Ag-driven type Ihypersensitivity when human MCs and peripheral bloodbasophils were preincubated with C

60fullerenes This sup-

pression involved decreasing the level of reactive oxygenspecies (ROS) [16] In aMC-dependentmodel of anaphylaxisfullerenes prevented the release of histamine [16] In addi-tion polyhydroxylated fullerene derivatives might protectagainst oxidative stress in ischemia-reperfused lungs [81]C60

also suppressed the tumor necrosis factor alpha (TNF-120572) induced production of proinflammatory cytokines in vitroand inhibited the arthritis in vivo [27] Other studies indifferent animalmodels also showed the immunosuppressioneffects of fullerenes For example hydroxylated fullerenescould interfere with the innate immune system in fatheadminnow [31] Nanocrystalline fullerene showed cytotoxicityand promotive effects on tumor cell growth in vitro and invivo respectively which might be due to the suppression ofanticancer immune response of mice by fullerene [14]

313 Gold NPs The anti-inflammatory properties citrate-coatedGNPswere also reported Citrate coatedGNPs (21 nm)did not cause detectable organ or cell toxicity in mice [37]Studies also indicated that citrate-stabilized 5 nm and 15 nmGNPs inhibited cellular responses induced by interleukin 1beta (IL-1120573) and showed anti-inflammatory activity [38]

314 Silver NPs The studies on the immunotoxicity ofAgNPs are very limited AgNPs induced ROS and inflamma-tion [82 83] indicating its potential interference of immunesystem AgNPs (22 nm) exposure caused the downregulationof expression of Malt1 and Sema7a genes which were associ-ated with immune cell function followed by aberrant T celldifferentiation [39]

315 Magnetic NPs Some in vitro studies showed that ironoxide NPs did not induce inflammatory response on humanmonocyte-macrophages [84] and aortic endothelia cells [85]However high doses of iron oxide NPs may induce oxidativestress [86] When treated with PVA-coated SPION humanmonocyte-derived DCs showed a decreased antigen process-ing and CD4 (+) T cell stimulation capacity [87] Thesestudies suggested the potential immune impact of magneticNPs The immunomodulation of the iron oxide NPs wasmuch more complex in vivo Intratracheally administration

of high dose (4 times 500 120583gmouse) and intermediate dose (4 times250 120583gmouse) of iron oxide NPs with a diameter of 35 plusmn14 nm or 147 plusmn 48 nm inhibited the allergic Th2-dominatedresponse induced by ovalbumin (OVA) The low dose (4 times100 120583gmouse) of iron oxide particles (147 plusmn 48 nm) hadno significant effect while the low dose (4 times 100 120583gmouse)of particles (35 plusmn 14 nm) had an adjuvant effect on theTh2 response to OVA [45] A single intratracheal instillation(250 375 or 500120583gmouse) or four-time repeated instillation(500120583gmouse times 4) showed that both NPs induced lunginflammation and decreased pulmonary immune responsesagainst sheep erythrocytes In another study intravenouslyadministration of iron oxide NPs (587 nm) in doses le 10mgironkg shifted the Th1Th2 immunobalance towards theTh2-dominant direction and suppressed the delayed-typehypersensitivity in OVA-sensitized mice [44] Furthermorerepeated instillations resulted in a reduction of inflammationthan single instillation [88]

316 CeO2NPs Due to their reducibility cerium oxide NPs

(nanoceria) were found to have the ability to reduce ROSandmay be used as a novel therapeutic tool for inflammationtreatment [73] Some in vitro studies indicated that nanoceriawith a small diameter caused a significant anti-inflammatoryeffect [73 89 90] For example nanoceria with a diameterof 3ndash5 nm scavenged free radicals inhibited inflammatorymediator production in J774A1 the murine macrophages[73] A recent study reported that the same size of nanoceriainducedAPCs to secrete IL-10 and induced aTh2-dominatedT cell proliferation The nanoceria (5ndash8 nm) showed aneffective antioxidant property in cardiac progenitor cells andprotected the cardiac progenitor cells from H

2O2-induced

cytotoxicity In addition in vivo investigation on immunecells of the sea urchin indicated that nanoceria suppressed theinnate immunity when force-fed 1mL 10minus2 gL 50ndash60 nm ofnanoceria [91]

317 Quantum Dots As efficient energy donors [92] QDscan induce the generation of ROS by transferring energyto nearby oxygen molecules In vitro studies have shownthat QDs induced production of ROS and led to multipleorganelle damage and cell death [93 94] Preexposure toa dose at 10minus7 to 10minus3 120583gmL CdTe QDs suppressed theimmune responses of J774A1 macrophage to bacteria byreducing NO TNF-120572 KCCXCL-1 and IL-8 production[95] These in vitro studies suggested that QDs might havehigh immunotoxicity In vivo studies also showed similarresults CdTe QDs (16 4 and 8mgL for 24 h at 15∘C)significantly decreased the viability of hemocytes as wellas number of hemocytes capable of ingesting fluorescentbeads in Elliption complanata mussels [50] The immuno-suppression was also observed in Juvenile rainbow troutWhen 5 10 and 20 nM CdSCdTe QDs were exposed toJuvenile rainbow trout for 96 h at 15∘C the leukocyte countsviability and both resting and active phagocytic activity weresignificantly reduced [51] QDs affected the proliferation ofimmune cells but did not induce immune response includingcytokine production [96] Size of QDs aggregates may affect

the immune response of QDs Large CdSCdTe QDs aggre-gates (25ndash100 nm) reduced phagocytosis more than smallerNPs (lt25 nm) on bivalves (Mytilus edulis and Elliptio com-planata) and fish (Oncorhynchus mykiss) [97] Thereforecaution is needed to overcome this barrier when QDs areapplied in clinical treatment

318 Polymeric NPs In vivo studies indicated that somepolymeric NPs inhibited inflammation but had no effect onhost immunity [54 98] NPs produced by particle replicationin nonwetting template technology remained in the lungs forup to 7 days without triggering host immunity after intra-tracheal administration of 50 120583gmouse [98] PolystyreneNPs (50 nm) inhibited lung inflammation by intratrachealadministration of 200120583gmouse after allergen challengeThisinhibition was due to the modulation of DCs functions NPsinhibited expansion of CD11c+MHCIIhi DCs in the lungs anddraining lymph node and allergen-laden CD11bhiMHCIIhiDCs in the lungs [54] In addition polystyrene particles havethe potential to halt the disease process in autoimmunityFor example antigen-decorated polystyrene particles with adiameter of 500 nm induced T-cell tolerance and amelioratedexperimental autoimmune encephalomyelitis by inactivatingpathogenic T cells [55]

32 Immunostimulation

321 CarbonNanotubes CNTs induced immunostimulationin vitro and in vivo The oropharyngeal aspiration of MWC-NTs (1 2 and 4mgkg) in C57BL6 mice induced inflam-mation (30 days postinstillation) in lungs [20 21] MWCNTswere translocated progressively into the spleen reached amaximumof 48 h after intraperitoneally (ip) administrationwhich caused the lymphocytic hyperplasia and increasedoxidative stress in the spleen [99] Subcutaneous adminis-tration of MWCNTs with total dose of 10mg for two scinjections in BALBc mice induced acute immunologicalreactions for 1 week (activation of complement and increasedproinflammatory cytokines) However the accumulation ofMWCNTs and injury was not observed in spleen [24]MWC-NTs injected intravenously activated Th2 immune responseby elevating Th2 cytokines and increasing number of CD4+and CD8+ T cell in the spleen [23] In other studies CNTsshowed allergy adjuvant effect in inflammatory mass Forexample SWCNTs andMWCNTs exhibited adjuvant activityto the OVA-sensitized mice [25 100] MWCNTs aggravatedasthma and induced fibrosis in OVA-sensitized lungs butshowed no response with healthy pulmonary The resultsindicated that these NPs could bring harm to asthma patientsbut not health ones [25] In recent in vitro studies MWCNTsincreased the release of a series of cytokines in peripheralblood mononuclear cells (PBMCs) from healthy donorsafter stimulation with toll-like receptor (TLR) agonists orT cell mitogen However MWCNTs suppressed immuneresponses in PBMCs frommite-allergic subjects These stud-ies suggest that MWCNTs may either stimulate or suppressimmune system depending on their immune cell target[101]

322 Graphene GO could induce healthy DCs to differen-tion and maturation at varying degrees [102] but suppressthe antigen-delivering ability of OVA-loaded DCs to Tlymphocytes [103]This inhibitionwas associatedwith down-regulation of subunit LMP7 of immunoproteasome in cellswhich is responsible for antigens processing in DCs [103]Whenmacrophage cells RAW2647 were incubated with GOtoll-like receptor (TLR4TLR9-) 6 modulated autophagy andinflammatory responses occurred [104] In addition PVP-coated GO exhibited lower immunogenicity than GO on theaspect of inducing maturation and differentiation of DCs[102] PVP-coated GO enhanced the physiological activityof macrophages which showed anti-phagocytosis abilityagainst macrophages and delayed the apoptotic process ofT lymphocytes [102] This advantage makes PVP-coated GOa promising candidate of immunoadjuvant The effect oftwo sizes (2120583m and 350 nm) of the GO in response tomicrophages was investigated [105] These two NPs hadequal uptake amount in macrophages but microsized GOinduced stronger inflammation responses and showed diver-gent intracellular locations compared to nanosized GO [105]This result demonstrated that lateral dimension of GO playsan important role in the regulation of cellular responsesRecent studies demonstrated that intravenously deliveredgraphene nanosheets induced site-specificTh2 inflammatoryresponses in the lungs via the IL-33ST2 axis [23] Thiseffect may cause host defense and exacerbation of allergicdiseases However more studies in vivo are needed to assessand eliminate the potential immunomodulation of graphene-based materials to ensure their safety for applications inbiomedicine

323 Fullerene Some studies showed that C60have immun-

ostimulatory properties [28ndash30 103 106] After instillationC60upregulated gene expression of various proinflammatory

cytokines (IL-1 TNF-120572 IL-6) andTh1 cytokines (IL-12 IFN-120574) in mice Besides inflammation C

60could activate the

immune system The carboxyfullerene could prolong theinfiltrating neutrophils to enhance the bactericidal activity ofneutrophils [30] Other studies indicated that fullerene mayenhance the ability of DCs to stimulate T cells and further-more activated cells of innate immune system by enhancingproduction of IL-6 and an activation of natural killer (NK)cells [103 106] In addition immunization of mice with aC60

fullerene derivative conjugated to bovine thyroglobulincould produce a population of fullerene-specific antibodieswhich included a subpopulation that cross-reacted with a C

fullerene [29]

324 Gold NPs GNPs with different surface modifica-tion showed different immunogenicity in organisms Theimmunogenicity of GNPs coated with C-terminal 19 kDafragment of merozoite surface protein 1 (MSP-1

19) was an

important vaccine candidate In this study GNPs showedpoor immunogenicity in mice but enhanced antibodyresponse when formulated with alum [15] However GNPscoated with monosaccharide or disaccharides could initiatethe immune response by activating the macrophages [107]

BioMed Research International 9

Some studies indicated that high concentrations of PEGcoated on GNPs could induce antibody production andtrigger immune responses High doses of injected PEG-coated GNPs were cleared through these mechanisms [3233]

GNPs can also induce inflammatory responses in vivoWell-dispersed PEG-coated GNPs (13 nm) can be recognizedby host defense mechanism and induce acute inflammationand apoptosis in the liver [34] If inflamed tissues are exposedstronger immune responses may be induced [108] Whenexposed to sensitized mice 40 nm GNPs could lead to athreefold increase in airway hyperreactivity and increase thenumber of neutrophils and macrophages [36]

325 Silver NPs Intratracheal instillation of AgNPs with adiameter of 5225 plusmn 2364 nm could enhance the respiratoryimmune function through oxidative stress and inducedinflammation in the respiratoryWhen alveolar macrophageswere activated by AgNPs to cause phagocytosis the alve-olar macrophages generated ROS and free radicals whichresulted in oxidative stress The normal function of alveolarmacrophages and epithelial cells was subsequently affectedThis led to oversecretion of cytokines and oxides which thencaused the stimulation of the respiratory immune function[40] These opposite results may be due to the differentdiameters of NPs Covalent conjugation of Ag to solid corenanobeads with different diameters ranging from 002 to2 120583m was found localized into DCs (DEC205+ CD40+CD86+) in draining lymph nodes and induced high levels ofIFN-120574 production and high antibody titers in tumor-bearingmice [41]

326 CeO2NPs Instillation of 100 120583g nanoceria with a

diameter of 8 nm in C57BL6 mice revealed that the NPsinduced inflammation in pulmonary system by activatingMCs [46] Other studies using bigger sizes showed the sameeffect Single intratracheal instillation of 20 nm nanoceriaat 015ndash7mgkg caused a dose-dependent inflammation andlung injury [47] The intratracheal instillation of 20ndash30 nmnanoceria (241m2g) with doses of 50 and 150 cm2mouseinduced both acute and chronic neutrophilicmildly cyto-toxic inflammation [48] Inhalation of 55 nm nanoceriawith an average aerosol concentration of 641mgm3 for 4 hinduced cytotoxicity via oxidative stress and led to a chronicinflammatory response including up regulation of IL-1120573TNF-120572 and IL-6 [49]

327 Silica NPs 30 nm amorphous silica NPs were inves-tigated in PBMCs and purified monocytes These NPscould induce inflammatory response as production of IL-1120573 IL-8 and ROS This result indicated the potential ofsilica NPs to evoke innate immune reactions [109] Otherreports showed that 30 and 70 nm silica NPs inducedhigher production of TNF-120572 in RAW2647 cells and strongerinflammatory responses (IL-5uarr IL-6uarr MCP-1uarr keratinocytechemoattractantuarr) than 300 and 1000 nm particles in vivo

through intraperitoneally injection The 70 nm particle-induced TNF-120572 production was dependent on the produc-tion of ROS and activation of mitogen activated proteinkinases (MAPKs) However modification of carboxyl groupson 70 nmparticles dramatically suppressed the inflammatoryresponses [52] As well Kupffer cells stimulated by 15 nmsilica NPs released large amounts of ROS TNF-120572 and NOThe viability of Buffalo rat liver (BRL) cells was reduced aftercultured with silica NP-stimulated Kupffer cells The authorsalso studied the intravenous injections of silica NPs with asingle dose of 50mgkg It caused hepatic inflammation andoxidative stress [53]

328 Polymeric NPs Polymer-based NPs were shown to beeffective adjuvants in vaccination [72 110 111] These poly-mers have the ability to activate cellular immune responsesin the host [112] For example N-trimethyl chitosan-mono-N-carboxymethyl chitosan (TMCMCC) NPs appeared tobe very promising as an adjuvant and delivery system forantigens Intranasal vaccination with tetanus toxoid loadedTMCMCC NPs (2835 plusmn 25 nm) was shown to induceboth the mucosal and systemic immune response (enhancedantibody response) The enhanced immunoglobulin G (IgG)immune response could be explained by the sustained releaseof the toxoid [113]

Some polymer NPs were reported to activate immunesystem through modulating the activation and capabilityof immune cells such as dendritic cells and T cells [114ndash116] Amphiphilic NPs possessed pathogen-mimicking prop-erties by activating DCs similar to lipopolysaccharide (LPS)thus it has the ability to activate innate immune response[114] Poly(methyl vinyl ether-co-maleic anhydride) NPs(149 plusmn 2 nm) activated DCs through TLR stimulation ininnate immune system [115] As well the sulfonate (245 nm)and phosphonate-functionalized (227 nm) polystyrene NPsinduced the maturation of immature DCs and significantlyenhancedT cells stimulatory capacity indicating a shift toTh1response [116]

329 Other NPs Dendrimers have the ability to stimu-late immune system and can be used as potential candi-dates for vaccines [76] Maltose-functionalized dendrimer-peptide complex is a potential DC-based vaccine candi-date by stimulating DC and activating the immune system[117] Research also showed that Pan-DR-binding epitope-derivatized-dendrimer could reduce the effective dose ofliposomal amphotericin B inmurine cutaneous leishmaniasisand enhance adaptive immunity by activating strong parasitespecific T-cell responses [56]

Protein NPs have shown immunostimulating propertiesin recent studies [118ndash120] Self-assembled protein NPs thatdisplayed epitopes of the repeat sequence in circumsporo-zoite protein of plasmodium falciparum (PfCSP) elicited astrong immune response against PfCSP [119 121] In additionprotein NPs mimic viruses have the ability to facilitate DCsactivation and cross-presentationThese proteinNPs codeliv-ered with peptide epitopes to DCs showed an increased andprolonged CD8+ T cell activation [120]

4 The Factors Affecting Immunomodulationof NPs

Many factors contribute to immunomodulation of NPs Thenature of NPs such as composition surface chemistry sizeshape and protein-binding ability dominates these interac-tions Besides individual difference and exposure route alsocontribute to immunomodulation of NPs

41 Composition Composition of NPs lays a vital role inthe interactions between NPs and immune system Forexample QDs showed high immunotoxicity [50 51] becausethey release heavy metal ions Some other NPs exhibit lessimmunotoxicity [17 23 39 44 54] immunogenic [15 32]or no effect [45] The different core of NPs gave differentreaction in allergy mass For example CNTs and GNPsshowed adjuvant effect and led to hypersensitivity in theseallergy masses [25 26 36] while fullerene often showedimmunosuppression [14 31]

42 Surface Chemistry For NPs with the same compositionsurface properties may also affect the immune system Engi-neered NPs such as CNTs fullerenes GNPs and silica NPscan be modified with diverse surface chemistry This mayalter their immune response both in vitro and in vivo

Eighty diversely functionalized multiwall nanotube(MWNT) induced different levels of protein bindingcytotoxicity and immune responses (Figure 2) [124] The

modification of MWCNTs significantly alleviated nuclearfactor kappa B (NF-120581B) activation and reduced immuno-toxicity ofMWCNTs in BALBcmice [125] Carboxyfullereneactivated immune system of C57BL6 mice by prolongingthe infiltrating neutrophils to enhance the bactericidalactivity of neutrophils [30] while hydroxylated fullerenesinterferedwith the innate immune system in fatheadminnow[31] MWCNTs-PEG induced less generation of ROS andcytotoxicity in macrophages than MWCNTs-COOH whichwas in correspondence with the lower cellular uptake ofMWCNTs-PEG [126] The monolayer-protected GNPs invivo were studied Simple place-exchange reactions withinthe monolayer by short chain mercaptotetraethylene glycolhave been used The short chain at lower concentrations didnot trigger the immune system to produce anti-PEG antibody[33] However high concentration mixed monolayer coatedNPs initiated an immune response [32] Silica NPs (70 nm)induced strong inflammation by intraperitoneal injectionbut these inflammatory responses could be dramaticallysuppressed by surface modification by carboxyl groups [52]The toxicity of porous silica NPs to immune cells was surfacechemistry and surface charge-dependent Compare tosurface hydrophobicity surface charge had stronger impacton NPsrsquo immunotoxicity in vitro and in vivo Positivelycharged hydrophobic NPs showed more DNA damage thannegatively charged hydrophilic NPs [127]

43 Size Size is another important parameter that deter-mines the interaction with organisms When examinedimmunity is induced by a series of differentially sized (2040 49 67 93 101 and 123 nm) polystyrene nanobeads IFN-120574 induction from CD8+ T cells was limited to 40 and 49 nmbeads while 93ndash123 nmbeads inducedCD4+ T cell activationand increased IL-4 levelThese results showed that the size ofnanobead for vaccination could influence the type 1type 2cytokine balance This would be useful in the developmentof vaccines against common human pathogens [128] 200 nmNPs increased more antigen-specific polyfunctional CD4+ Tcells as compared to 30 nm NPs The immunoactivity of dis-accharides coated GNPs is strongly dependent on size Theyused 2 and 5 nm GNPs coated with disaccharides These NPsactivated the macrophages and induced the proliferation of Tcells and the increase of IL-2 levels The 5 nmNPs performedfar better than 2 nmones (increasedAPC proliferationMHCII expression T cell proliferation and IL-2 expression) [107]Other researches indicated that single instillation (250 375or 500 120583gmouse) of 35 plusmn 14 nm iron oxide NPs inducedhigher levels of inflammation and immunodepression than147plusmn48 nm ones [88] Repeated intratracheal administrationof high dose (4 times 500120583gmouse) and intermediate dose (4 times250 120583gmouse) of the same NPs inhibited the allergic Th2-dominated response induced by OVA The low dose (4 times100 120583gmouse) of 147 plusmn 48 nm iron oxide particles had nosignificant effect but the low dose (4 times 100 120583gmouse) of 35plusmn14 nm particles had an adjuvant effect on theTh2 response toOVA [45] Aggregate size may also affect the immunotoxicityof QDs The toxicity of CdSCdTe QDs was size dependentLarge CdSCdTe QD aggregates (25 nmndash100 nm) reduced

44 Protein Binding When NPs enter the body throughinjection they firstly interact with blood [129] The plasmaprotein binding on the NPs surface such as apolipoprotein Eand transferrinmay contribute to the activationdeactivationof receptor-dependent signaling [130]

The amount and types of proteins adsorbed on the NPsaffect the interactions of cells and NPs and the biologicalresponses [131 132]The composition surface characteristicsand shape of NPs affect the manners that the proteinsbind to them [129 133ndash136] The blood proteins adsorbedonto the NPs include immunoglobulins apolipoproteins andproteins of the complement system among many othersThese proteins may act as signals for immune responses [137138] Furthermore NPs may induce conformational changesin the structure of adsorbed proteins Negatively chargedpoly(acrylic acid-) conjugated GNPs bound with fibrinogenand induced the unfolding of this protein which promotedinteraction with Mac-1 an integrin receptor This activationincreased the NF-120581B signalling pathway and released inflam-matory cytokines [139]

45 Exposure Route Exposure route is another factor affect-ing the immunomodulation ofNPsTheoutcomes of immuneresponse are dependent on entrance of NPs In the lungsDCs pulmonary epithelium and macrophages play animportant role in handling foreign materials In the bloodleukocyte such as neutrophil eosinophil basophil lympho-cyte and monocyte play a vital role Single intratrachealinstillation of 500120583gmouse iron oxide NPs (35 plusmn 14 nmand 147 plusmn 48 nm) induced lung inflammation and decreasedpulmonary immune responses against sheep erythrocytes[88] Pharyngeal aspiration of SWCNTs modified systemicimmunity by modulating DCs function [19] Intravenouslyadministration of iron oxide NPs (587 nm) could sup-press the infiltration and functional activity of Th1 cellsand macrophages [44] Intravenous injection of graphenenanosheets activated a Th2 immune response which con-sisted of neutrophilic influx and a significant increase inIL-5 IL-13 IL-33 in the bronchoalvelar lavage fluid [23]The dosage of administration is also important Intratrachealinjection of iron oxide NPs (35 plusmn 14 nm) inhibited theallergic response in OVA-sensitized mice at a dosage of 4 times250120583gmouse or 4 times 500 120583gmouse but showed adjuvanteffect at a dosage of 4 times 100 120583gmouse [45]

5 The Mechanisms of ImmunomodulationInduced by NPs

NPs interact with both innate and adaptive immune cellsaffect their functions and disturb immune system (Figure 3)

Inflammation is an important response of immune sys-tem which can be induced by NPs evidenced by the pro-duction of cytokines or chemokines Oxidative stress causedby NPs is reported to be the main downstream events ofthe inflammation NPs have large surface areas and strong

oxidative abilities than normal particles [140] Oxidativedamage induced by NPs is an important factor of immuneimbalance [11] Many types of NPs have been shown toproduce ROS in vitro and in vivo and enhance immunefunction or inflammatory response [40 49 53 86 141] Freeradical-induced tissue damage plays an important role ininflammatory diseases [142 143]

The signal pathway to induce ROS and mediate inflam-mation was reported Among them TLR4 signaling pathwaywas documented GO could induce intracellular ROS whichdecreased the viability of macrophages and induced necrosisby a TLR4 signaling pathway (Figure 4) [144] TLR is areceptor of the innate immune system and innate immunitycould be triggered by stimulating TLRs and lead to strongadaptive immunity [115] Activation of the TLR pathwayscould induce chronic inflammation and ROS [145] Resentresearch indicated that quantum dots could activate myeloiddifferentiation primary response gene 88 (MyD88 which isan adapter protein to activate NF-120581B) dependent-TLRs inmcrophages and activated NF-120581B [146]

NF-120581B pathway is another key regulator of immuneresponse [125 147ndash149] As an important regulator of proin-flammatory gene expression synthesis of cytokines suchas IL-1120573 IL-6 IL-8 and TNF-120572 is mediated by NF-120581B

Activation of NF-120581B may induce human inflammatory dis-eases [150 151] It was reported that negatively chargedpoly(acrylic acid-) conjugated GNP activated the NF-120581Bsignalling pathway in THP-1 cells The cells released inflam-matory cytokines including TNF-120572 and IL-8 [139] Andcitrate-stabilized 10 nm GNPs could induce activation of anNF-120581B regulated luciferase reporter in murine B-lymphocytecell line (CH12LX) and altered the cell function [152]

NPs may also disturb the immune balance by inappro-priate maturationactivation of APCs such as DCs [26 153]Intratracheal instillation of 43 nmMIONs the alveolar regionof BALBc mice could generate a significant number ofexosomes These exosomes were quickly eliminated from thealveolar region into systemic circulation and transferred theirsignals to the immune system which resulted in maturationof DCs and activation of splenic T cells and the exosome-induced T-cell activation is more efficient in OVA-sensitizedmice [42 43] Cytotoxicity to immune cells may contribute toimmunosuppression of NPs QDs may decrease the viabilityof hemocytes in Elliption complanata mussels [50] andreduced phagocytosis on bivalves and fish [97]

Recent reports indicated that NPs could modulate thehomeostasis of immune cells including the shift of Th1Th2balance [43 44 89] and monocyte homeostasis [154] Forexample magnetic iron oxide NPs activated the T cellsinduced a Th1 polarization and aggravated inflammation[43]Other studies showed that SWCNTs accentuatedThcellsimmunity includingTh2 (IL-4uarr IL-5uarr and IL-13uarr) andTh17

(IL-17Auarr IL-23uarr) The inappropriate maturationactivationof APCs such as DCs might be responsible for these accen-tuated Th cells immunity [26 153] The normal immunesystem keeps a Th1Th2 balance in order to achieve anappropriate immune response Selectively activating Th1 orTh2 cells results in immune deviation and breaks the balanceof immune system In addition MWCNTs could selectivelydecrease phagocytosis-competent monocytes and promoteadhesion of the phagocytosis-incompetent monocytes inblood flow [154]

6 Conclusion

The immune response of NPs is like a double-edged swordin nanomedicine applications by bringing both benefits andharms We should take advantage of the benefits from theimmunomodulating properties of NPs and on the otherhand avoid the undesirable immune responses in order tominimize the systemic side effects The factors affecting theimmune response are complex including particle compo-sition size surface chemistry plasma protein binding andexposure route Investigation of the relationship betweenproperties of NPs and systemic immune response is crucialfor their application in medicine and other areas Althoughtreatments of acute and long-term immune toxicities havebeen developed current approaches of prediction preven-tion and treatment of nanoimmunomodulation are stilllacking encouraging further in-depth studies

(reduced T-cell-dependent antibody against sheep erythro-cytes and T-cell proliferative ability and decreased naturalkiller cell activity) This suppression was accompanied byincreased spleen gene expression of interleukin-10 (IL-10)which is an anti-inflammatory cytokine and NAD(P)H oxi-doreductase [17] Other studies showed that pharyngeal aspi-ration of SWCNTs (40 120583gmouse) in BALBc mice inducedpulmonary inflammation and suppressed the responsivenessof T cell 7 days postexposure This immunosuppression wasassociated with the direct effects of SWCNTs on DCs [19]

312 Fullerene As a strong free-radical scavenger [79]fullerene has anti-inflammatory effects The antioxidativeanti-inflammatory activities of novel fullerenes have beenreported [80] Fullerene could suppress Ag-driven type Ihypersensitivity when human MCs and peripheral bloodbasophils were preincubated with C

60fullerenes This sup-

pression involved decreasing the level of reactive oxygenspecies (ROS) [16] In aMC-dependentmodel of anaphylaxisfullerenes prevented the release of histamine [16] In addi-tion polyhydroxylated fullerene derivatives might protectagainst oxidative stress in ischemia-reperfused lungs [81]C60

also suppressed the tumor necrosis factor alpha (TNF-120572) induced production of proinflammatory cytokines in vitroand inhibited the arthritis in vivo [27] Other studies indifferent animalmodels also showed the immunosuppressioneffects of fullerenes For example hydroxylated fullerenescould interfere with the innate immune system in fatheadminnow [31] Nanocrystalline fullerene showed cytotoxicityand promotive effects on tumor cell growth in vitro and invivo respectively which might be due to the suppression ofanticancer immune response of mice by fullerene [14]

313 Gold NPs The anti-inflammatory properties citrate-coatedGNPswere also reported Citrate coatedGNPs (21 nm)did not cause detectable organ or cell toxicity in mice [37]Studies also indicated that citrate-stabilized 5 nm and 15 nmGNPs inhibited cellular responses induced by interleukin 1beta (IL-1120573) and showed anti-inflammatory activity [38]

314 Silver NPs The studies on the immunotoxicity ofAgNPs are very limited AgNPs induced ROS and inflamma-tion [82 83] indicating its potential interference of immunesystem AgNPs (22 nm) exposure caused the downregulationof expression of Malt1 and Sema7a genes which were associ-ated with immune cell function followed by aberrant T celldifferentiation [39]

315 Magnetic NPs Some in vitro studies showed that ironoxide NPs did not induce inflammatory response on humanmonocyte-macrophages [84] and aortic endothelia cells [85]However high doses of iron oxide NPs may induce oxidativestress [86] When treated with PVA-coated SPION humanmonocyte-derived DCs showed a decreased antigen process-ing and CD4 (+) T cell stimulation capacity [87] Thesestudies suggested the potential immune impact of magneticNPs The immunomodulation of the iron oxide NPs wasmuch more complex in vivo Intratracheally administration

of high dose (4 times 500 120583gmouse) and intermediate dose (4 times250 120583gmouse) of iron oxide NPs with a diameter of 35 plusmn14 nm or 147 plusmn 48 nm inhibited the allergic Th2-dominatedresponse induced by ovalbumin (OVA) The low dose (4 times100 120583gmouse) of iron oxide particles (147 plusmn 48 nm) hadno significant effect while the low dose (4 times 100 120583gmouse)of particles (35 plusmn 14 nm) had an adjuvant effect on theTh2 response to OVA [45] A single intratracheal instillation(250 375 or 500120583gmouse) or four-time repeated instillation(500120583gmouse times 4) showed that both NPs induced lunginflammation and decreased pulmonary immune responsesagainst sheep erythrocytes In another study intravenouslyadministration of iron oxide NPs (587 nm) in doses le 10mgironkg shifted the Th1Th2 immunobalance towards theTh2-dominant direction and suppressed the delayed-typehypersensitivity in OVA-sensitized mice [44] Furthermorerepeated instillations resulted in a reduction of inflammationthan single instillation [88]

316 CeO2NPs Due to their reducibility cerium oxide NPs

(nanoceria) were found to have the ability to reduce ROSandmay be used as a novel therapeutic tool for inflammationtreatment [73] Some in vitro studies indicated that nanoceriawith a small diameter caused a significant anti-inflammatoryeffect [73 89 90] For example nanoceria with a diameterof 3ndash5 nm scavenged free radicals inhibited inflammatorymediator production in J774A1 the murine macrophages[73] A recent study reported that the same size of nanoceriainducedAPCs to secrete IL-10 and induced aTh2-dominatedT cell proliferation The nanoceria (5ndash8 nm) showed aneffective antioxidant property in cardiac progenitor cells andprotected the cardiac progenitor cells from H

2O2-induced

cytotoxicity In addition in vivo investigation on immunecells of the sea urchin indicated that nanoceria suppressed theinnate immunity when force-fed 1mL 10minus2 gL 50ndash60 nm ofnanoceria [91]

317 Quantum Dots As efficient energy donors [92] QDscan induce the generation of ROS by transferring energyto nearby oxygen molecules In vitro studies have shownthat QDs induced production of ROS and led to multipleorganelle damage and cell death [93 94] Preexposure toa dose at 10minus7 to 10minus3 120583gmL CdTe QDs suppressed theimmune responses of J774A1 macrophage to bacteria byreducing NO TNF-120572 KCCXCL-1 and IL-8 production[95] These in vitro studies suggested that QDs might havehigh immunotoxicity In vivo studies also showed similarresults CdTe QDs (16 4 and 8mgL for 24 h at 15∘C)significantly decreased the viability of hemocytes as wellas number of hemocytes capable of ingesting fluorescentbeads in Elliption complanata mussels [50] The immuno-suppression was also observed in Juvenile rainbow troutWhen 5 10 and 20 nM CdSCdTe QDs were exposed toJuvenile rainbow trout for 96 h at 15∘C the leukocyte countsviability and both resting and active phagocytic activity weresignificantly reduced [51] QDs affected the proliferation ofimmune cells but did not induce immune response includingcytokine production [96] Size of QDs aggregates may affect

the immune response of QDs Large CdSCdTe QDs aggre-gates (25ndash100 nm) reduced phagocytosis more than smallerNPs (lt25 nm) on bivalves (Mytilus edulis and Elliptio com-planata) and fish (Oncorhynchus mykiss) [97] Thereforecaution is needed to overcome this barrier when QDs areapplied in clinical treatment

318 Polymeric NPs In vivo studies indicated that somepolymeric NPs inhibited inflammation but had no effect onhost immunity [54 98] NPs produced by particle replicationin nonwetting template technology remained in the lungs forup to 7 days without triggering host immunity after intra-tracheal administration of 50 120583gmouse [98] PolystyreneNPs (50 nm) inhibited lung inflammation by intratrachealadministration of 200120583gmouse after allergen challengeThisinhibition was due to the modulation of DCs functions NPsinhibited expansion of CD11c+MHCIIhi DCs in the lungs anddraining lymph node and allergen-laden CD11bhiMHCIIhiDCs in the lungs [54] In addition polystyrene particles havethe potential to halt the disease process in autoimmunityFor example antigen-decorated polystyrene particles with adiameter of 500 nm induced T-cell tolerance and amelioratedexperimental autoimmune encephalomyelitis by inactivatingpathogenic T cells [55]

32 Immunostimulation

321 CarbonNanotubes CNTs induced immunostimulationin vitro and in vivo The oropharyngeal aspiration of MWC-NTs (1 2 and 4mgkg) in C57BL6 mice induced inflam-mation (30 days postinstillation) in lungs [20 21] MWCNTswere translocated progressively into the spleen reached amaximumof 48 h after intraperitoneally (ip) administrationwhich caused the lymphocytic hyperplasia and increasedoxidative stress in the spleen [99] Subcutaneous adminis-tration of MWCNTs with total dose of 10mg for two scinjections in BALBc mice induced acute immunologicalreactions for 1 week (activation of complement and increasedproinflammatory cytokines) However the accumulation ofMWCNTs and injury was not observed in spleen [24]MWC-NTs injected intravenously activated Th2 immune responseby elevating Th2 cytokines and increasing number of CD4+and CD8+ T cell in the spleen [23] In other studies CNTsshowed allergy adjuvant effect in inflammatory mass Forexample SWCNTs andMWCNTs exhibited adjuvant activityto the OVA-sensitized mice [25 100] MWCNTs aggravatedasthma and induced fibrosis in OVA-sensitized lungs butshowed no response with healthy pulmonary The resultsindicated that these NPs could bring harm to asthma patientsbut not health ones [25] In recent in vitro studies MWCNTsincreased the release of a series of cytokines in peripheralblood mononuclear cells (PBMCs) from healthy donorsafter stimulation with toll-like receptor (TLR) agonists orT cell mitogen However MWCNTs suppressed immuneresponses in PBMCs frommite-allergic subjects These stud-ies suggest that MWCNTs may either stimulate or suppressimmune system depending on their immune cell target[101]

322 Graphene GO could induce healthy DCs to differen-tion and maturation at varying degrees [102] but suppressthe antigen-delivering ability of OVA-loaded DCs to Tlymphocytes [103]This inhibitionwas associatedwith down-regulation of subunit LMP7 of immunoproteasome in cellswhich is responsible for antigens processing in DCs [103]Whenmacrophage cells RAW2647 were incubated with GOtoll-like receptor (TLR4TLR9-) 6 modulated autophagy andinflammatory responses occurred [104] In addition PVP-coated GO exhibited lower immunogenicity than GO on theaspect of inducing maturation and differentiation of DCs[102] PVP-coated GO enhanced the physiological activityof macrophages which showed anti-phagocytosis abilityagainst macrophages and delayed the apoptotic process ofT lymphocytes [102] This advantage makes PVP-coated GOa promising candidate of immunoadjuvant The effect oftwo sizes (2120583m and 350 nm) of the GO in response tomicrophages was investigated [105] These two NPs hadequal uptake amount in macrophages but microsized GOinduced stronger inflammation responses and showed diver-gent intracellular locations compared to nanosized GO [105]This result demonstrated that lateral dimension of GO playsan important role in the regulation of cellular responsesRecent studies demonstrated that intravenously deliveredgraphene nanosheets induced site-specificTh2 inflammatoryresponses in the lungs via the IL-33ST2 axis [23] Thiseffect may cause host defense and exacerbation of allergicdiseases However more studies in vivo are needed to assessand eliminate the potential immunomodulation of graphene-based materials to ensure their safety for applications inbiomedicine

323 Fullerene Some studies showed that C60have immun-

ostimulatory properties [28ndash30 103 106] After instillationC60upregulated gene expression of various proinflammatory

cytokines (IL-1 TNF-120572 IL-6) andTh1 cytokines (IL-12 IFN-120574) in mice Besides inflammation C

60could activate the

immune system The carboxyfullerene could prolong theinfiltrating neutrophils to enhance the bactericidal activity ofneutrophils [30] Other studies indicated that fullerene mayenhance the ability of DCs to stimulate T cells and further-more activated cells of innate immune system by enhancingproduction of IL-6 and an activation of natural killer (NK)cells [103 106] In addition immunization of mice with aC60

fullerene derivative conjugated to bovine thyroglobulincould produce a population of fullerene-specific antibodieswhich included a subpopulation that cross-reacted with a C

324 Gold NPs GNPs with different surface modifica-tion showed different immunogenicity in organisms Theimmunogenicity of GNPs coated with C-terminal 19 kDafragment of merozoite surface protein 1 (MSP-1

19) was an

important vaccine candidate In this study GNPs showedpoor immunogenicity in mice but enhanced antibodyresponse when formulated with alum [15] However GNPscoated with monosaccharide or disaccharides could initiatethe immune response by activating the macrophages [107]

BioMed Research International 9

Some studies indicated that high concentrations of PEGcoated on GNPs could induce antibody production andtrigger immune responses High doses of injected PEG-coated GNPs were cleared through these mechanisms [3233]

GNPs can also induce inflammatory responses in vivoWell-dispersed PEG-coated GNPs (13 nm) can be recognizedby host defense mechanism and induce acute inflammationand apoptosis in the liver [34] If inflamed tissues are exposedstronger immune responses may be induced [108] Whenexposed to sensitized mice 40 nm GNPs could lead to athreefold increase in airway hyperreactivity and increase thenumber of neutrophils and macrophages [36]

325 Silver NPs Intratracheal instillation of AgNPs with adiameter of 5225 plusmn 2364 nm could enhance the respiratoryimmune function through oxidative stress and inducedinflammation in the respiratoryWhen alveolar macrophageswere activated by AgNPs to cause phagocytosis the alve-olar macrophages generated ROS and free radicals whichresulted in oxidative stress The normal function of alveolarmacrophages and epithelial cells was subsequently affectedThis led to oversecretion of cytokines and oxides which thencaused the stimulation of the respiratory immune function[40] These opposite results may be due to the differentdiameters of NPs Covalent conjugation of Ag to solid corenanobeads with different diameters ranging from 002 to2 120583m was found localized into DCs (DEC205+ CD40+CD86+) in draining lymph nodes and induced high levels ofIFN-120574 production and high antibody titers in tumor-bearingmice [41]

326 CeO2NPs Instillation of 100 120583g nanoceria with a

diameter of 8 nm in C57BL6 mice revealed that the NPsinduced inflammation in pulmonary system by activatingMCs [46] Other studies using bigger sizes showed the sameeffect Single intratracheal instillation of 20 nm nanoceriaat 015ndash7mgkg caused a dose-dependent inflammation andlung injury [47] The intratracheal instillation of 20ndash30 nmnanoceria (241m2g) with doses of 50 and 150 cm2mouseinduced both acute and chronic neutrophilicmildly cyto-toxic inflammation [48] Inhalation of 55 nm nanoceriawith an average aerosol concentration of 641mgm3 for 4 hinduced cytotoxicity via oxidative stress and led to a chronicinflammatory response including up regulation of IL-1120573TNF-120572 and IL-6 [49]

327 Silica NPs 30 nm amorphous silica NPs were inves-tigated in PBMCs and purified monocytes These NPscould induce inflammatory response as production of IL-1120573 IL-8 and ROS This result indicated the potential ofsilica NPs to evoke innate immune reactions [109] Otherreports showed that 30 and 70 nm silica NPs inducedhigher production of TNF-120572 in RAW2647 cells and strongerinflammatory responses (IL-5uarr IL-6uarr MCP-1uarr keratinocytechemoattractantuarr) than 300 and 1000 nm particles in vivo

through intraperitoneally injection The 70 nm particle-induced TNF-120572 production was dependent on the produc-tion of ROS and activation of mitogen activated proteinkinases (MAPKs) However modification of carboxyl groupson 70 nmparticles dramatically suppressed the inflammatoryresponses [52] As well Kupffer cells stimulated by 15 nmsilica NPs released large amounts of ROS TNF-120572 and NOThe viability of Buffalo rat liver (BRL) cells was reduced aftercultured with silica NP-stimulated Kupffer cells The authorsalso studied the intravenous injections of silica NPs with asingle dose of 50mgkg It caused hepatic inflammation andoxidative stress [53]

328 Polymeric NPs Polymer-based NPs were shown to beeffective adjuvants in vaccination [72 110 111] These poly-mers have the ability to activate cellular immune responsesin the host [112] For example N-trimethyl chitosan-mono-N-carboxymethyl chitosan (TMCMCC) NPs appeared tobe very promising as an adjuvant and delivery system forantigens Intranasal vaccination with tetanus toxoid loadedTMCMCC NPs (2835 plusmn 25 nm) was shown to induceboth the mucosal and systemic immune response (enhancedantibody response) The enhanced immunoglobulin G (IgG)immune response could be explained by the sustained releaseof the toxoid [113]

Some polymer NPs were reported to activate immunesystem through modulating the activation and capabilityof immune cells such as dendritic cells and T cells [114ndash116] Amphiphilic NPs possessed pathogen-mimicking prop-erties by activating DCs similar to lipopolysaccharide (LPS)thus it has the ability to activate innate immune response[114] Poly(methyl vinyl ether-co-maleic anhydride) NPs(149 plusmn 2 nm) activated DCs through TLR stimulation ininnate immune system [115] As well the sulfonate (245 nm)and phosphonate-functionalized (227 nm) polystyrene NPsinduced the maturation of immature DCs and significantlyenhancedT cells stimulatory capacity indicating a shift toTh1response [116]

329 Other NPs Dendrimers have the ability to stimu-late immune system and can be used as potential candi-dates for vaccines [76] Maltose-functionalized dendrimer-peptide complex is a potential DC-based vaccine candi-date by stimulating DC and activating the immune system[117] Research also showed that Pan-DR-binding epitope-derivatized-dendrimer could reduce the effective dose ofliposomal amphotericin B inmurine cutaneous leishmaniasisand enhance adaptive immunity by activating strong parasitespecific T-cell responses [56]

Protein NPs have shown immunostimulating propertiesin recent studies [118ndash120] Self-assembled protein NPs thatdisplayed epitopes of the repeat sequence in circumsporo-zoite protein of plasmodium falciparum (PfCSP) elicited astrong immune response against PfCSP [119 121] In additionprotein NPs mimic viruses have the ability to facilitate DCsactivation and cross-presentationThese proteinNPs codeliv-ered with peptide epitopes to DCs showed an increased andprolonged CD8+ T cell activation [120]

A lipidNPwas investigated in aDNAvaccine applicationThis NP which decorated with stearyl-conjugated KALAan 120572-helical peptide (sequence WEAKLAKALAKALAK-HLAKALAKALKACEA) showed enhancement of transgeneexpression this enhancement was closely related to immune-activation [122] A cationic solid-lipid NP was used as a vac-cine to deliver a DNA vaccine against visceral leishmaniasisHigh levels of IFN-120574 and low levels of IL-10 production weredetected in BALBc mice after administration of the DNAvaccine delivered by this cationic solid-lipid NP This NPinduced a strongTh1 immune response indicating its poten-tial as therapeutic agent against visceral leishmaniasis [57]Nanolipoprotein conjugated with TLR agonists monophos-phoryl lipid A or CpG oligodeoxynucleotides significantlyenhanced the immunostimulatory profiles compared to theagonists alone Moreover the BALBc mice pretreated withCpGnanolipoprotein coloaded nanoconstructs but not CpGalone survived a lethal influenza challenge [58] Researchalso indicated that intravenous injection of liposome-DNAcomplexes elicited production of IFN-120572 and IFN-120573 in vivowhich suggested that the liposome-DNA complexes caninduce inflammation and cause systemic toxicity [123] Inanother study it was reported that Doxil an PEGylatedliposomal formulation of doxorubicin may cause hyper-sensitivity reactions while the standard doxorubicin didnot indicating that liposomes might be responsible for thishypersensitivity [59] It was speculated that the complementsystem activation by Doxil may play a key role in this effect[59]

4 The Factors Affecting Immunomodulationof NPs

Many factors contribute to immunomodulation of NPs Thenature of NPs such as composition surface chemistry sizeshape and protein-binding ability dominates these interac-tions Besides individual difference and exposure route alsocontribute to immunomodulation of NPs

41 Composition Composition of NPs lays a vital role inthe interactions between NPs and immune system Forexample QDs showed high immunotoxicity [50 51] becausethey release heavy metal ions Some other NPs exhibit lessimmunotoxicity [17 23 39 44 54] immunogenic [15 32]or no effect [45] The different core of NPs gave differentreaction in allergy mass For example CNTs and GNPsshowed adjuvant effect and led to hypersensitivity in theseallergy masses [25 26 36] while fullerene often showedimmunosuppression [14 31]

42 Surface Chemistry For NPs with the same compositionsurface properties may also affect the immune system Engi-neered NPs such as CNTs fullerenes GNPs and silica NPscan be modified with diverse surface chemistry This mayalter their immune response both in vitro and in vivo

Eighty diversely functionalized multiwall nanotube(MWNT) induced different levels of protein bindingcytotoxicity and immune responses (Figure 2) [124] The

modification of MWCNTs significantly alleviated nuclearfactor kappa B (NF-120581B) activation and reduced immuno-toxicity ofMWCNTs in BALBcmice [125] Carboxyfullereneactivated immune system of C57BL6 mice by prolongingthe infiltrating neutrophils to enhance the bactericidalactivity of neutrophils [30] while hydroxylated fullerenesinterferedwith the innate immune system in fatheadminnow[31] MWCNTs-PEG induced less generation of ROS andcytotoxicity in macrophages than MWCNTs-COOH whichwas in correspondence with the lower cellular uptake ofMWCNTs-PEG [126] The monolayer-protected GNPs invivo were studied Simple place-exchange reactions withinthe monolayer by short chain mercaptotetraethylene glycolhave been used The short chain at lower concentrations didnot trigger the immune system to produce anti-PEG antibody[33] However high concentration mixed monolayer coatedNPs initiated an immune response [32] Silica NPs (70 nm)induced strong inflammation by intraperitoneal injectionbut these inflammatory responses could be dramaticallysuppressed by surface modification by carboxyl groups [52]The toxicity of porous silica NPs to immune cells was surfacechemistry and surface charge-dependent Compare tosurface hydrophobicity surface charge had stronger impacton NPsrsquo immunotoxicity in vitro and in vivo Positivelycharged hydrophobic NPs showed more DNA damage thannegatively charged hydrophilic NPs [127]

43 Size Size is another important parameter that deter-mines the interaction with organisms When examinedimmunity is induced by a series of differentially sized (2040 49 67 93 101 and 123 nm) polystyrene nanobeads IFN-120574 induction from CD8+ T cells was limited to 40 and 49 nmbeads while 93ndash123 nmbeads inducedCD4+ T cell activationand increased IL-4 levelThese results showed that the size ofnanobead for vaccination could influence the type 1type 2cytokine balance This would be useful in the developmentof vaccines against common human pathogens [128] 200 nmNPs increased more antigen-specific polyfunctional CD4+ Tcells as compared to 30 nm NPs The immunoactivity of dis-accharides coated GNPs is strongly dependent on size Theyused 2 and 5 nm GNPs coated with disaccharides These NPsactivated the macrophages and induced the proliferation of Tcells and the increase of IL-2 levels The 5 nmNPs performedfar better than 2 nmones (increasedAPC proliferationMHCII expression T cell proliferation and IL-2 expression) [107]Other researches indicated that single instillation (250 375or 500 120583gmouse) of 35 plusmn 14 nm iron oxide NPs inducedhigher levels of inflammation and immunodepression than147plusmn48 nm ones [88] Repeated intratracheal administrationof high dose (4 times 500120583gmouse) and intermediate dose (4 times250 120583gmouse) of the same NPs inhibited the allergic Th2-dominated response induced by OVA The low dose (4 times100 120583gmouse) of 147 plusmn 48 nm iron oxide particles had nosignificant effect but the low dose (4 times 100 120583gmouse) of 35plusmn14 nm particles had an adjuvant effect on theTh2 response toOVA [45] Aggregate size may also affect the immunotoxicityof QDs The toxicity of CdSCdTe QDs was size dependentLarge CdSCdTe QD aggregates (25 nmndash100 nm) reduced

44 Protein Binding When NPs enter the body throughinjection they firstly interact with blood [129] The plasmaprotein binding on the NPs surface such as apolipoprotein Eand transferrinmay contribute to the activationdeactivationof receptor-dependent signaling [130]

The amount and types of proteins adsorbed on the NPsaffect the interactions of cells and NPs and the biologicalresponses [131 132]The composition surface characteristicsand shape of NPs affect the manners that the proteinsbind to them [129 133ndash136] The blood proteins adsorbedonto the NPs include immunoglobulins apolipoproteins andproteins of the complement system among many othersThese proteins may act as signals for immune responses [137138] Furthermore NPs may induce conformational changesin the structure of adsorbed proteins Negatively chargedpoly(acrylic acid-) conjugated GNPs bound with fibrinogenand induced the unfolding of this protein which promotedinteraction with Mac-1 an integrin receptor This activationincreased the NF-120581B signalling pathway and released inflam-matory cytokines [139]

45 Exposure Route Exposure route is another factor affect-ing the immunomodulation ofNPsTheoutcomes of immuneresponse are dependent on entrance of NPs In the lungsDCs pulmonary epithelium and macrophages play animportant role in handling foreign materials In the bloodleukocyte such as neutrophil eosinophil basophil lympho-cyte and monocyte play a vital role Single intratrachealinstillation of 500120583gmouse iron oxide NPs (35 plusmn 14 nmand 147 plusmn 48 nm) induced lung inflammation and decreasedpulmonary immune responses against sheep erythrocytes[88] Pharyngeal aspiration of SWCNTs modified systemicimmunity by modulating DCs function [19] Intravenouslyadministration of iron oxide NPs (587 nm) could sup-press the infiltration and functional activity of Th1 cellsand macrophages [44] Intravenous injection of graphenenanosheets activated a Th2 immune response which con-sisted of neutrophilic influx and a significant increase inIL-5 IL-13 IL-33 in the bronchoalvelar lavage fluid [23]The dosage of administration is also important Intratrachealinjection of iron oxide NPs (35 plusmn 14 nm) inhibited theallergic response in OVA-sensitized mice at a dosage of 4 times250120583gmouse or 4 times 500 120583gmouse but showed adjuvanteffect at a dosage of 4 times 100 120583gmouse [45]

5 The Mechanisms of ImmunomodulationInduced by NPs

NPs interact with both innate and adaptive immune cellsaffect their functions and disturb immune system (Figure 3)

Inflammation is an important response of immune sys-tem which can be induced by NPs evidenced by the pro-duction of cytokines or chemokines Oxidative stress causedby NPs is reported to be the main downstream events ofthe inflammation NPs have large surface areas and strong

oxidative abilities than normal particles [140] Oxidativedamage induced by NPs is an important factor of immuneimbalance [11] Many types of NPs have been shown toproduce ROS in vitro and in vivo and enhance immunefunction or inflammatory response [40 49 53 86 141] Freeradical-induced tissue damage plays an important role ininflammatory diseases [142 143]

The signal pathway to induce ROS and mediate inflam-mation was reported Among them TLR4 signaling pathwaywas documented GO could induce intracellular ROS whichdecreased the viability of macrophages and induced necrosisby a TLR4 signaling pathway (Figure 4) [144] TLR is areceptor of the innate immune system and innate immunitycould be triggered by stimulating TLRs and lead to strongadaptive immunity [115] Activation of the TLR pathwayscould induce chronic inflammation and ROS [145] Resentresearch indicated that quantum dots could activate myeloiddifferentiation primary response gene 88 (MyD88 which isan adapter protein to activate NF-120581B) dependent-TLRs inmcrophages and activated NF-120581B [146]

NF-120581B pathway is another key regulator of immuneresponse [125 147ndash149] As an important regulator of proin-flammatory gene expression synthesis of cytokines suchas IL-1120573 IL-6 IL-8 and TNF-120572 is mediated by NF-120581B

Activation of NF-120581B may induce human inflammatory dis-eases [150 151] It was reported that negatively chargedpoly(acrylic acid-) conjugated GNP activated the NF-120581Bsignalling pathway in THP-1 cells The cells released inflam-matory cytokines including TNF-120572 and IL-8 [139] Andcitrate-stabilized 10 nm GNPs could induce activation of anNF-120581B regulated luciferase reporter in murine B-lymphocytecell line (CH12LX) and altered the cell function [152]

NPs may also disturb the immune balance by inappro-priate maturationactivation of APCs such as DCs [26 153]Intratracheal instillation of 43 nmMIONs the alveolar regionof BALBc mice could generate a significant number ofexosomes These exosomes were quickly eliminated from thealveolar region into systemic circulation and transferred theirsignals to the immune system which resulted in maturationof DCs and activation of splenic T cells and the exosome-induced T-cell activation is more efficient in OVA-sensitizedmice [42 43] Cytotoxicity to immune cells may contribute toimmunosuppression of NPs QDs may decrease the viabilityof hemocytes in Elliption complanata mussels [50] andreduced phagocytosis on bivalves and fish [97]

Recent reports indicated that NPs could modulate thehomeostasis of immune cells including the shift of Th1Th2balance [43 44 89] and monocyte homeostasis [154] Forexample magnetic iron oxide NPs activated the T cellsinduced a Th1 polarization and aggravated inflammation[43]Other studies showed that SWCNTs accentuatedThcellsimmunity includingTh2 (IL-4uarr IL-5uarr and IL-13uarr) andTh17

(IL-17Auarr IL-23uarr) The inappropriate maturationactivationof APCs such as DCs might be responsible for these accen-tuated Th cells immunity [26 153] The normal immunesystem keeps a Th1Th2 balance in order to achieve anappropriate immune response Selectively activating Th1 orTh2 cells results in immune deviation and breaks the balanceof immune system In addition MWCNTs could selectivelydecrease phagocytosis-competent monocytes and promoteadhesion of the phagocytosis-incompetent monocytes inblood flow [154]

6 Conclusion

The immune response of NPs is like a double-edged swordin nanomedicine applications by bringing both benefits andharms We should take advantage of the benefits from theimmunomodulating properties of NPs and on the otherhand avoid the undesirable immune responses in order tominimize the systemic side effects The factors affecting theimmune response are complex including particle compo-sition size surface chemistry plasma protein binding andexposure route Investigation of the relationship betweenproperties of NPs and systemic immune response is crucialfor their application in medicine and other areas Althoughtreatments of acute and long-term immune toxicities havebeen developed current approaches of prediction preven-tion and treatment of nanoimmunomodulation are stilllacking encouraging further in-depth studies

(reduced T-cell-dependent antibody against sheep erythro-cytes and T-cell proliferative ability and decreased naturalkiller cell activity) This suppression was accompanied byincreased spleen gene expression of interleukin-10 (IL-10)which is an anti-inflammatory cytokine and NAD(P)H oxi-doreductase [17] Other studies showed that pharyngeal aspi-ration of SWCNTs (40 120583gmouse) in BALBc mice inducedpulmonary inflammation and suppressed the responsivenessof T cell 7 days postexposure This immunosuppression wasassociated with the direct effects of SWCNTs on DCs [19]

312 Fullerene As a strong free-radical scavenger [79]fullerene has anti-inflammatory effects The antioxidativeanti-inflammatory activities of novel fullerenes have beenreported [80] Fullerene could suppress Ag-driven type Ihypersensitivity when human MCs and peripheral bloodbasophils were preincubated with C

60fullerenes This sup-

pression involved decreasing the level of reactive oxygenspecies (ROS) [16] In aMC-dependentmodel of anaphylaxisfullerenes prevented the release of histamine [16] In addi-tion polyhydroxylated fullerene derivatives might protectagainst oxidative stress in ischemia-reperfused lungs [81]C60

also suppressed the tumor necrosis factor alpha (TNF-120572) induced production of proinflammatory cytokines in vitroand inhibited the arthritis in vivo [27] Other studies indifferent animalmodels also showed the immunosuppressioneffects of fullerenes For example hydroxylated fullerenescould interfere with the innate immune system in fatheadminnow [31] Nanocrystalline fullerene showed cytotoxicityand promotive effects on tumor cell growth in vitro and invivo respectively which might be due to the suppression ofanticancer immune response of mice by fullerene [14]

313 Gold NPs The anti-inflammatory properties citrate-coatedGNPswere also reported Citrate coatedGNPs (21 nm)did not cause detectable organ or cell toxicity in mice [37]Studies also indicated that citrate-stabilized 5 nm and 15 nmGNPs inhibited cellular responses induced by interleukin 1beta (IL-1120573) and showed anti-inflammatory activity [38]

314 Silver NPs The studies on the immunotoxicity ofAgNPs are very limited AgNPs induced ROS and inflamma-tion [82 83] indicating its potential interference of immunesystem AgNPs (22 nm) exposure caused the downregulationof expression of Malt1 and Sema7a genes which were associ-ated with immune cell function followed by aberrant T celldifferentiation [39]

315 Magnetic NPs Some in vitro studies showed that ironoxide NPs did not induce inflammatory response on humanmonocyte-macrophages [84] and aortic endothelia cells [85]However high doses of iron oxide NPs may induce oxidativestress [86] When treated with PVA-coated SPION humanmonocyte-derived DCs showed a decreased antigen process-ing and CD4 (+) T cell stimulation capacity [87] Thesestudies suggested the potential immune impact of magneticNPs The immunomodulation of the iron oxide NPs wasmuch more complex in vivo Intratracheally administration

of high dose (4 times 500 120583gmouse) and intermediate dose (4 times250 120583gmouse) of iron oxide NPs with a diameter of 35 plusmn14 nm or 147 plusmn 48 nm inhibited the allergic Th2-dominatedresponse induced by ovalbumin (OVA) The low dose (4 times100 120583gmouse) of iron oxide particles (147 plusmn 48 nm) hadno significant effect while the low dose (4 times 100 120583gmouse)of particles (35 plusmn 14 nm) had an adjuvant effect on theTh2 response to OVA [45] A single intratracheal instillation(250 375 or 500120583gmouse) or four-time repeated instillation(500120583gmouse times 4) showed that both NPs induced lunginflammation and decreased pulmonary immune responsesagainst sheep erythrocytes In another study intravenouslyadministration of iron oxide NPs (587 nm) in doses le 10mgironkg shifted the Th1Th2 immunobalance towards theTh2-dominant direction and suppressed the delayed-typehypersensitivity in OVA-sensitized mice [44] Furthermorerepeated instillations resulted in a reduction of inflammationthan single instillation [88]

316 CeO2NPs Due to their reducibility cerium oxide NPs

(nanoceria) were found to have the ability to reduce ROSandmay be used as a novel therapeutic tool for inflammationtreatment [73] Some in vitro studies indicated that nanoceriawith a small diameter caused a significant anti-inflammatoryeffect [73 89 90] For example nanoceria with a diameterof 3ndash5 nm scavenged free radicals inhibited inflammatorymediator production in J774A1 the murine macrophages[73] A recent study reported that the same size of nanoceriainducedAPCs to secrete IL-10 and induced aTh2-dominatedT cell proliferation The nanoceria (5ndash8 nm) showed aneffective antioxidant property in cardiac progenitor cells andprotected the cardiac progenitor cells from H

2O2-induced

cytotoxicity In addition in vivo investigation on immunecells of the sea urchin indicated that nanoceria suppressed theinnate immunity when force-fed 1mL 10minus2 gL 50ndash60 nm ofnanoceria [91]

317 Quantum Dots As efficient energy donors [92] QDscan induce the generation of ROS by transferring energyto nearby oxygen molecules In vitro studies have shownthat QDs induced production of ROS and led to multipleorganelle damage and cell death [93 94] Preexposure toa dose at 10minus7 to 10minus3 120583gmL CdTe QDs suppressed theimmune responses of J774A1 macrophage to bacteria byreducing NO TNF-120572 KCCXCL-1 and IL-8 production[95] These in vitro studies suggested that QDs might havehigh immunotoxicity In vivo studies also showed similarresults CdTe QDs (16 4 and 8mgL for 24 h at 15∘C)significantly decreased the viability of hemocytes as wellas number of hemocytes capable of ingesting fluorescentbeads in Elliption complanata mussels [50] The immuno-suppression was also observed in Juvenile rainbow troutWhen 5 10 and 20 nM CdSCdTe QDs were exposed toJuvenile rainbow trout for 96 h at 15∘C the leukocyte countsviability and both resting and active phagocytic activity weresignificantly reduced [51] QDs affected the proliferation ofimmune cells but did not induce immune response includingcytokine production [96] Size of QDs aggregates may affect

the immune response of QDs Large CdSCdTe QDs aggre-gates (25ndash100 nm) reduced phagocytosis more than smallerNPs (lt25 nm) on bivalves (Mytilus edulis and Elliptio com-planata) and fish (Oncorhynchus mykiss) [97] Thereforecaution is needed to overcome this barrier when QDs areapplied in clinical treatment

318 Polymeric NPs In vivo studies indicated that somepolymeric NPs inhibited inflammation but had no effect onhost immunity [54 98] NPs produced by particle replicationin nonwetting template technology remained in the lungs forup to 7 days without triggering host immunity after intra-tracheal administration of 50 120583gmouse [98] PolystyreneNPs (50 nm) inhibited lung inflammation by intratrachealadministration of 200120583gmouse after allergen challengeThisinhibition was due to the modulation of DCs functions NPsinhibited expansion of CD11c+MHCIIhi DCs in the lungs anddraining lymph node and allergen-laden CD11bhiMHCIIhiDCs in the lungs [54] In addition polystyrene particles havethe potential to halt the disease process in autoimmunityFor example antigen-decorated polystyrene particles with adiameter of 500 nm induced T-cell tolerance and amelioratedexperimental autoimmune encephalomyelitis by inactivatingpathogenic T cells [55]

321 CarbonNanotubes CNTs induced immunostimulationin vitro and in vivo The oropharyngeal aspiration of MWC-NTs (1 2 and 4mgkg) in C57BL6 mice induced inflam-mation (30 days postinstillation) in lungs [20 21] MWCNTswere translocated progressively into the spleen reached amaximumof 48 h after intraperitoneally (ip) administrationwhich caused the lymphocytic hyperplasia and increasedoxidative stress in the spleen [99] Subcutaneous adminis-tration of MWCNTs with total dose of 10mg for two scinjections in BALBc mice induced acute immunologicalreactions for 1 week (activation of complement and increasedproinflammatory cytokines) However the accumulation ofMWCNTs and injury was not observed in spleen [24]MWC-NTs injected intravenously activated Th2 immune responseby elevating Th2 cytokines and increasing number of CD4+and CD8+ T cell in the spleen [23] In other studies CNTsshowed allergy adjuvant effect in inflammatory mass Forexample SWCNTs andMWCNTs exhibited adjuvant activityto the OVA-sensitized mice [25 100] MWCNTs aggravatedasthma and induced fibrosis in OVA-sensitized lungs butshowed no response with healthy pulmonary The resultsindicated that these NPs could bring harm to asthma patientsbut not health ones [25] In recent in vitro studies MWCNTsincreased the release of a series of cytokines in peripheralblood mononuclear cells (PBMCs) from healthy donorsafter stimulation with toll-like receptor (TLR) agonists orT cell mitogen However MWCNTs suppressed immuneresponses in PBMCs frommite-allergic subjects These stud-ies suggest that MWCNTs may either stimulate or suppressimmune system depending on their immune cell target[101]

322 Graphene GO could induce healthy DCs to differen-tion and maturation at varying degrees [102] but suppressthe antigen-delivering ability of OVA-loaded DCs to Tlymphocytes [103]This inhibitionwas associatedwith down-regulation of subunit LMP7 of immunoproteasome in cellswhich is responsible for antigens processing in DCs [103]Whenmacrophage cells RAW2647 were incubated with GOtoll-like receptor (TLR4TLR9-) 6 modulated autophagy andinflammatory responses occurred [104] In addition PVP-coated GO exhibited lower immunogenicity than GO on theaspect of inducing maturation and differentiation of DCs[102] PVP-coated GO enhanced the physiological activityof macrophages which showed anti-phagocytosis abilityagainst macrophages and delayed the apoptotic process ofT lymphocytes [102] This advantage makes PVP-coated GOa promising candidate of immunoadjuvant The effect oftwo sizes (2120583m and 350 nm) of the GO in response tomicrophages was investigated [105] These two NPs hadequal uptake amount in macrophages but microsized GOinduced stronger inflammation responses and showed diver-gent intracellular locations compared to nanosized GO [105]This result demonstrated that lateral dimension of GO playsan important role in the regulation of cellular responsesRecent studies demonstrated that intravenously deliveredgraphene nanosheets induced site-specificTh2 inflammatoryresponses in the lungs via the IL-33ST2 axis [23] Thiseffect may cause host defense and exacerbation of allergicdiseases However more studies in vivo are needed to assessand eliminate the potential immunomodulation of graphene-based materials to ensure their safety for applications inbiomedicine

323 Fullerene Some studies showed that C60have immun-

ostimulatory properties [28ndash30 103 106] After instillationC60upregulated gene expression of various proinflammatory

cytokines (IL-1 TNF-120572 IL-6) andTh1 cytokines (IL-12 IFN-120574) in mice Besides inflammation C

60could activate the

immune system The carboxyfullerene could prolong theinfiltrating neutrophils to enhance the bactericidal activity ofneutrophils [30] Other studies indicated that fullerene mayenhance the ability of DCs to stimulate T cells and further-more activated cells of innate immune system by enhancingproduction of IL-6 and an activation of natural killer (NK)cells [103 106] In addition immunization of mice with aC60

fullerene derivative conjugated to bovine thyroglobulincould produce a population of fullerene-specific antibodieswhich included a subpopulation that cross-reacted with a C

324 Gold NPs GNPs with different surface modifica-tion showed different immunogenicity in organisms Theimmunogenicity of GNPs coated with C-terminal 19 kDafragment of merozoite surface protein 1 (MSP-1

19) was an

important vaccine candidate In this study GNPs showedpoor immunogenicity in mice but enhanced antibodyresponse when formulated with alum [15] However GNPscoated with monosaccharide or disaccharides could initiatethe immune response by activating the macrophages [107]

Some studies indicated that high concentrations of PEGcoated on GNPs could induce antibody production andtrigger immune responses High doses of injected PEG-coated GNPs were cleared through these mechanisms [3233]

GNPs can also induce inflammatory responses in vivoWell-dispersed PEG-coated GNPs (13 nm) can be recognizedby host defense mechanism and induce acute inflammationand apoptosis in the liver [34] If inflamed tissues are exposedstronger immune responses may be induced [108] Whenexposed to sensitized mice 40 nm GNPs could lead to athreefold increase in airway hyperreactivity and increase thenumber of neutrophils and macrophages [36]

325 Silver NPs Intratracheal instillation of AgNPs with adiameter of 5225 plusmn 2364 nm could enhance the respiratoryimmune function through oxidative stress and inducedinflammation in the respiratoryWhen alveolar macrophageswere activated by AgNPs to cause phagocytosis the alve-olar macrophages generated ROS and free radicals whichresulted in oxidative stress The normal function of alveolarmacrophages and epithelial cells was subsequently affectedThis led to oversecretion of cytokines and oxides which thencaused the stimulation of the respiratory immune function[40] These opposite results may be due to the differentdiameters of NPs Covalent conjugation of Ag to solid corenanobeads with different diameters ranging from 002 to2 120583m was found localized into DCs (DEC205+ CD40+CD86+) in draining lymph nodes and induced high levels ofIFN-120574 production and high antibody titers in tumor-bearingmice [41]

326 CeO2NPs Instillation of 100 120583g nanoceria with a

diameter of 8 nm in C57BL6 mice revealed that the NPsinduced inflammation in pulmonary system by activatingMCs [46] Other studies using bigger sizes showed the sameeffect Single intratracheal instillation of 20 nm nanoceriaat 015ndash7mgkg caused a dose-dependent inflammation andlung injury [47] The intratracheal instillation of 20ndash30 nmnanoceria (241m2g) with doses of 50 and 150 cm2mouseinduced both acute and chronic neutrophilicmildly cyto-toxic inflammation [48] Inhalation of 55 nm nanoceriawith an average aerosol concentration of 641mgm3 for 4 hinduced cytotoxicity via oxidative stress and led to a chronicinflammatory response including up regulation of IL-1120573TNF-120572 and IL-6 [49]

327 Silica NPs 30 nm amorphous silica NPs were inves-tigated in PBMCs and purified monocytes These NPscould induce inflammatory response as production of IL-1120573 IL-8 and ROS This result indicated the potential ofsilica NPs to evoke innate immune reactions [109] Otherreports showed that 30 and 70 nm silica NPs inducedhigher production of TNF-120572 in RAW2647 cells and strongerinflammatory responses (IL-5uarr IL-6uarr MCP-1uarr keratinocytechemoattractantuarr) than 300 and 1000 nm particles in vivo

through intraperitoneally injection The 70 nm particle-induced TNF-120572 production was dependent on the produc-tion of ROS and activation of mitogen activated proteinkinases (MAPKs) However modification of carboxyl groupson 70 nmparticles dramatically suppressed the inflammatoryresponses [52] As well Kupffer cells stimulated by 15 nmsilica NPs released large amounts of ROS TNF-120572 and NOThe viability of Buffalo rat liver (BRL) cells was reduced aftercultured with silica NP-stimulated Kupffer cells The authorsalso studied the intravenous injections of silica NPs with asingle dose of 50mgkg It caused hepatic inflammation andoxidative stress [53]

328 Polymeric NPs Polymer-based NPs were shown to beeffective adjuvants in vaccination [72 110 111] These poly-mers have the ability to activate cellular immune responsesin the host [112] For example N-trimethyl chitosan-mono-N-carboxymethyl chitosan (TMCMCC) NPs appeared tobe very promising as an adjuvant and delivery system forantigens Intranasal vaccination with tetanus toxoid loadedTMCMCC NPs (2835 plusmn 25 nm) was shown to induceboth the mucosal and systemic immune response (enhancedantibody response) The enhanced immunoglobulin G (IgG)immune response could be explained by the sustained releaseof the toxoid [113]

Some polymer NPs were reported to activate immunesystem through modulating the activation and capabilityof immune cells such as dendritic cells and T cells [114ndash116] Amphiphilic NPs possessed pathogen-mimicking prop-erties by activating DCs similar to lipopolysaccharide (LPS)thus it has the ability to activate innate immune response[114] Poly(methyl vinyl ether-co-maleic anhydride) NPs(149 plusmn 2 nm) activated DCs through TLR stimulation ininnate immune system [115] As well the sulfonate (245 nm)and phosphonate-functionalized (227 nm) polystyrene NPsinduced the maturation of immature DCs and significantlyenhancedT cells stimulatory capacity indicating a shift toTh1response [116]

329 Other NPs Dendrimers have the ability to stimu-late immune system and can be used as potential candi-dates for vaccines [76] Maltose-functionalized dendrimer-peptide complex is a potential DC-based vaccine candi-date by stimulating DC and activating the immune system[117] Research also showed that Pan-DR-binding epitope-derivatized-dendrimer could reduce the effective dose ofliposomal amphotericin B inmurine cutaneous leishmaniasisand enhance adaptive immunity by activating strong parasitespecific T-cell responses [56]

Protein NPs have shown immunostimulating propertiesin recent studies [118ndash120] Self-assembled protein NPs thatdisplayed epitopes of the repeat sequence in circumsporo-zoite protein of plasmodium falciparum (PfCSP) elicited astrong immune response against PfCSP [119 121] In additionprotein NPs mimic viruses have the ability to facilitate DCsactivation and cross-presentationThese proteinNPs codeliv-ered with peptide epitopes to DCs showed an increased andprolonged CD8+ T cell activation [120]

A lipidNPwas investigated in aDNAvaccine applicationThis NP which decorated with stearyl-conjugated KALAan 120572-helical peptide (sequence WEAKLAKALAKALAK-HLAKALAKALKACEA) showed enhancement of transgeneexpression this enhancement was closely related to immune-activation [122] A cationic solid-lipid NP was used as a vac-cine to deliver a DNA vaccine against visceral leishmaniasisHigh levels of IFN-120574 and low levels of IL-10 production weredetected in BALBc mice after administration of the DNAvaccine delivered by this cationic solid-lipid NP This NPinduced a strongTh1 immune response indicating its poten-tial as therapeutic agent against visceral leishmaniasis [57]Nanolipoprotein conjugated with TLR agonists monophos-phoryl lipid A or CpG oligodeoxynucleotides significantlyenhanced the immunostimulatory profiles compared to theagonists alone Moreover the BALBc mice pretreated withCpGnanolipoprotein coloaded nanoconstructs but not CpGalone survived a lethal influenza challenge [58] Researchalso indicated that intravenous injection of liposome-DNAcomplexes elicited production of IFN-120572 and IFN-120573 in vivowhich suggested that the liposome-DNA complexes caninduce inflammation and cause systemic toxicity [123] Inanother study it was reported that Doxil an PEGylatedliposomal formulation of doxorubicin may cause hyper-sensitivity reactions while the standard doxorubicin didnot indicating that liposomes might be responsible for thishypersensitivity [59] It was speculated that the complementsystem activation by Doxil may play a key role in this effect[59]

4 The Factors Affecting Immunomodulationof NPs

Many factors contribute to immunomodulation of NPs Thenature of NPs such as composition surface chemistry sizeshape and protein-binding ability dominates these interac-tions Besides individual difference and exposure route alsocontribute to immunomodulation of NPs

41 Composition Composition of NPs lays a vital role inthe interactions between NPs and immune system Forexample QDs showed high immunotoxicity [50 51] becausethey release heavy metal ions Some other NPs exhibit lessimmunotoxicity [17 23 39 44 54] immunogenic [15 32]or no effect [45] The different core of NPs gave differentreaction in allergy mass For example CNTs and GNPsshowed adjuvant effect and led to hypersensitivity in theseallergy masses [25 26 36] while fullerene often showedimmunosuppression [14 31]

42 Surface Chemistry For NPs with the same compositionsurface properties may also affect the immune system Engi-neered NPs such as CNTs fullerenes GNPs and silica NPscan be modified with diverse surface chemistry This mayalter their immune response both in vitro and in vivo

Eighty diversely functionalized multiwall nanotube(MWNT) induced different levels of protein bindingcytotoxicity and immune responses (Figure 2) [124] The

modification of MWCNTs significantly alleviated nuclearfactor kappa B (NF-120581B) activation and reduced immuno-toxicity ofMWCNTs in BALBcmice [125] Carboxyfullereneactivated immune system of C57BL6 mice by prolongingthe infiltrating neutrophils to enhance the bactericidalactivity of neutrophils [30] while hydroxylated fullerenesinterferedwith the innate immune system in fatheadminnow[31] MWCNTs-PEG induced less generation of ROS andcytotoxicity in macrophages than MWCNTs-COOH whichwas in correspondence with the lower cellular uptake ofMWCNTs-PEG [126] The monolayer-protected GNPs invivo were studied Simple place-exchange reactions withinthe monolayer by short chain mercaptotetraethylene glycolhave been used The short chain at lower concentrations didnot trigger the immune system to produce anti-PEG antibody[33] However high concentration mixed monolayer coatedNPs initiated an immune response [32] Silica NPs (70 nm)induced strong inflammation by intraperitoneal injectionbut these inflammatory responses could be dramaticallysuppressed by surface modification by carboxyl groups [52]The toxicity of porous silica NPs to immune cells was surfacechemistry and surface charge-dependent Compare tosurface hydrophobicity surface charge had stronger impacton NPsrsquo immunotoxicity in vitro and in vivo Positivelycharged hydrophobic NPs showed more DNA damage thannegatively charged hydrophilic NPs [127]

43 Size Size is another important parameter that deter-mines the interaction with organisms When examinedimmunity is induced by a series of differentially sized (2040 49 67 93 101 and 123 nm) polystyrene nanobeads IFN-120574 induction from CD8+ T cells was limited to 40 and 49 nmbeads while 93ndash123 nmbeads inducedCD4+ T cell activationand increased IL-4 levelThese results showed that the size ofnanobead for vaccination could influence the type 1type 2cytokine balance This would be useful in the developmentof vaccines against common human pathogens [128] 200 nmNPs increased more antigen-specific polyfunctional CD4+ Tcells as compared to 30 nm NPs The immunoactivity of dis-accharides coated GNPs is strongly dependent on size Theyused 2 and 5 nm GNPs coated with disaccharides These NPsactivated the macrophages and induced the proliferation of Tcells and the increase of IL-2 levels The 5 nmNPs performedfar better than 2 nmones (increasedAPC proliferationMHCII expression T cell proliferation and IL-2 expression) [107]Other researches indicated that single instillation (250 375or 500 120583gmouse) of 35 plusmn 14 nm iron oxide NPs inducedhigher levels of inflammation and immunodepression than147plusmn48 nm ones [88] Repeated intratracheal administrationof high dose (4 times 500120583gmouse) and intermediate dose (4 times250 120583gmouse) of the same NPs inhibited the allergic Th2-dominated response induced by OVA The low dose (4 times100 120583gmouse) of 147 plusmn 48 nm iron oxide particles had nosignificant effect but the low dose (4 times 100 120583gmouse) of 35plusmn14 nm particles had an adjuvant effect on theTh2 response toOVA [45] Aggregate size may also affect the immunotoxicityof QDs The toxicity of CdSCdTe QDs was size dependentLarge CdSCdTe QD aggregates (25 nmndash100 nm) reduced

44 Protein Binding When NPs enter the body throughinjection they firstly interact with blood [129] The plasmaprotein binding on the NPs surface such as apolipoprotein Eand transferrinmay contribute to the activationdeactivationof receptor-dependent signaling [130]

The amount and types of proteins adsorbed on the NPsaffect the interactions of cells and NPs and the biologicalresponses [131 132]The composition surface characteristicsand shape of NPs affect the manners that the proteinsbind to them [129 133ndash136] The blood proteins adsorbedonto the NPs include immunoglobulins apolipoproteins andproteins of the complement system among many othersThese proteins may act as signals for immune responses [137138] Furthermore NPs may induce conformational changesin the structure of adsorbed proteins Negatively chargedpoly(acrylic acid-) conjugated GNPs bound with fibrinogenand induced the unfolding of this protein which promotedinteraction with Mac-1 an integrin receptor This activationincreased the NF-120581B signalling pathway and released inflam-matory cytokines [139]

45 Exposure Route Exposure route is another factor affect-ing the immunomodulation ofNPsTheoutcomes of immuneresponse are dependent on entrance of NPs In the lungsDCs pulmonary epithelium and macrophages play animportant role in handling foreign materials In the bloodleukocyte such as neutrophil eosinophil basophil lympho-cyte and monocyte play a vital role Single intratrachealinstillation of 500120583gmouse iron oxide NPs (35 plusmn 14 nmand 147 plusmn 48 nm) induced lung inflammation and decreasedpulmonary immune responses against sheep erythrocytes[88] Pharyngeal aspiration of SWCNTs modified systemicimmunity by modulating DCs function [19] Intravenouslyadministration of iron oxide NPs (587 nm) could sup-press the infiltration and functional activity of Th1 cellsand macrophages [44] Intravenous injection of graphenenanosheets activated a Th2 immune response which con-sisted of neutrophilic influx and a significant increase inIL-5 IL-13 IL-33 in the bronchoalvelar lavage fluid [23]The dosage of administration is also important Intratrachealinjection of iron oxide NPs (35 plusmn 14 nm) inhibited theallergic response in OVA-sensitized mice at a dosage of 4 times250120583gmouse or 4 times 500 120583gmouse but showed adjuvanteffect at a dosage of 4 times 100 120583gmouse [45]

5 The Mechanisms of ImmunomodulationInduced by NPs

NPs interact with both innate and adaptive immune cellsaffect their functions and disturb immune system (Figure 3)

oxidative abilities than normal particles [140] Oxidativedamage induced by NPs is an important factor of immuneimbalance [11] Many types of NPs have been shown toproduce ROS in vitro and in vivo and enhance immunefunction or inflammatory response [40 49 53 86 141] Freeradical-induced tissue damage plays an important role ininflammatory diseases [142 143]

The signal pathway to induce ROS and mediate inflam-mation was reported Among them TLR4 signaling pathwaywas documented GO could induce intracellular ROS whichdecreased the viability of macrophages and induced necrosisby a TLR4 signaling pathway (Figure 4) [144] TLR is areceptor of the innate immune system and innate immunitycould be triggered by stimulating TLRs and lead to strongadaptive immunity [115] Activation of the TLR pathwayscould induce chronic inflammation and ROS [145] Resentresearch indicated that quantum dots could activate myeloiddifferentiation primary response gene 88 (MyD88 which isan adapter protein to activate NF-120581B) dependent-TLRs inmcrophages and activated NF-120581B [146]

NF-120581B pathway is another key regulator of immuneresponse [125 147ndash149] As an important regulator of proin-flammatory gene expression synthesis of cytokines suchas IL-1120573 IL-6 IL-8 and TNF-120572 is mediated by NF-120581B

Activation of NF-120581B may induce human inflammatory dis-eases [150 151] It was reported that negatively chargedpoly(acrylic acid-) conjugated GNP activated the NF-120581Bsignalling pathway in THP-1 cells The cells released inflam-matory cytokines including TNF-120572 and IL-8 [139] Andcitrate-stabilized 10 nm GNPs could induce activation of anNF-120581B regulated luciferase reporter in murine B-lymphocytecell line (CH12LX) and altered the cell function [152]

NPs may also disturb the immune balance by inappro-priate maturationactivation of APCs such as DCs [26 153]Intratracheal instillation of 43 nmMIONs the alveolar regionof BALBc mice could generate a significant number ofexosomes These exosomes were quickly eliminated from thealveolar region into systemic circulation and transferred theirsignals to the immune system which resulted in maturationof DCs and activation of splenic T cells and the exosome-induced T-cell activation is more efficient in OVA-sensitizedmice [42 43] Cytotoxicity to immune cells may contribute toimmunosuppression of NPs QDs may decrease the viabilityof hemocytes in Elliption complanata mussels [50] andreduced phagocytosis on bivalves and fish [97]

Recent reports indicated that NPs could modulate thehomeostasis of immune cells including the shift of Th1Th2balance [43 44 89] and monocyte homeostasis [154] Forexample magnetic iron oxide NPs activated the T cellsinduced a Th1 polarization and aggravated inflammation[43]Other studies showed that SWCNTs accentuatedThcellsimmunity includingTh2 (IL-4uarr IL-5uarr and IL-13uarr) andTh17

(IL-17Auarr IL-23uarr) The inappropriate maturationactivationof APCs such as DCs might be responsible for these accen-tuated Th cells immunity [26 153] The normal immunesystem keeps a Th1Th2 balance in order to achieve anappropriate immune response Selectively activating Th1 orTh2 cells results in immune deviation and breaks the balanceof immune system In addition MWCNTs could selectivelydecrease phagocytosis-competent monocytes and promoteadhesion of the phagocytosis-incompetent monocytes inblood flow [154]

6 Conclusion

The immune response of NPs is like a double-edged swordin nanomedicine applications by bringing both benefits andharms We should take advantage of the benefits from theimmunomodulating properties of NPs and on the otherhand avoid the undesirable immune responses in order tominimize the systemic side effects The factors affecting theimmune response are complex including particle compo-sition size surface chemistry plasma protein binding andexposure route Investigation of the relationship betweenproperties of NPs and systemic immune response is crucialfor their application in medicine and other areas Althoughtreatments of acute and long-term immune toxicities havebeen developed current approaches of prediction preven-tion and treatment of nanoimmunomodulation are stilllacking encouraging further in-depth studies

(reduced T-cell-dependent antibody against sheep erythro-cytes and T-cell proliferative ability and decreased naturalkiller cell activity) This suppression was accompanied byincreased spleen gene expression of interleukin-10 (IL-10)which is an anti-inflammatory cytokine and NAD(P)H oxi-doreductase [17] Other studies showed that pharyngeal aspi-ration of SWCNTs (40 120583gmouse) in BALBc mice inducedpulmonary inflammation and suppressed the responsivenessof T cell 7 days postexposure This immunosuppression wasassociated with the direct effects of SWCNTs on DCs [19]

312 Fullerene As a strong free-radical scavenger [79]fullerene has anti-inflammatory effects The antioxidativeanti-inflammatory activities of novel fullerenes have beenreported [80] Fullerene could suppress Ag-driven type Ihypersensitivity when human MCs and peripheral bloodbasophils were preincubated with C

60fullerenes This sup-

pression involved decreasing the level of reactive oxygenspecies (ROS) [16] In aMC-dependentmodel of anaphylaxisfullerenes prevented the release of histamine [16] In addi-tion polyhydroxylated fullerene derivatives might protectagainst oxidative stress in ischemia-reperfused lungs [81]C60

also suppressed the tumor necrosis factor alpha (TNF-120572) induced production of proinflammatory cytokines in vitroand inhibited the arthritis in vivo [27] Other studies indifferent animalmodels also showed the immunosuppressioneffects of fullerenes For example hydroxylated fullerenescould interfere with the innate immune system in fatheadminnow [31] Nanocrystalline fullerene showed cytotoxicityand promotive effects on tumor cell growth in vitro and invivo respectively which might be due to the suppression ofanticancer immune response of mice by fullerene [14]

313 Gold NPs The anti-inflammatory properties citrate-coatedGNPswere also reported Citrate coatedGNPs (21 nm)did not cause detectable organ or cell toxicity in mice [37]Studies also indicated that citrate-stabilized 5 nm and 15 nmGNPs inhibited cellular responses induced by interleukin 1beta (IL-1120573) and showed anti-inflammatory activity [38]

314 Silver NPs The studies on the immunotoxicity ofAgNPs are very limited AgNPs induced ROS and inflamma-tion [82 83] indicating its potential interference of immunesystem AgNPs (22 nm) exposure caused the downregulationof expression of Malt1 and Sema7a genes which were associ-ated with immune cell function followed by aberrant T celldifferentiation [39]

315 Magnetic NPs Some in vitro studies showed that ironoxide NPs did not induce inflammatory response on humanmonocyte-macrophages [84] and aortic endothelia cells [85]However high doses of iron oxide NPs may induce oxidativestress [86] When treated with PVA-coated SPION humanmonocyte-derived DCs showed a decreased antigen process-ing and CD4 (+) T cell stimulation capacity [87] Thesestudies suggested the potential immune impact of magneticNPs The immunomodulation of the iron oxide NPs wasmuch more complex in vivo Intratracheally administration

of high dose (4 times 500 120583gmouse) and intermediate dose (4 times250 120583gmouse) of iron oxide NPs with a diameter of 35 plusmn14 nm or 147 plusmn 48 nm inhibited the allergic Th2-dominatedresponse induced by ovalbumin (OVA) The low dose (4 times100 120583gmouse) of iron oxide particles (147 plusmn 48 nm) hadno significant effect while the low dose (4 times 100 120583gmouse)of particles (35 plusmn 14 nm) had an adjuvant effect on theTh2 response to OVA [45] A single intratracheal instillation(250 375 or 500120583gmouse) or four-time repeated instillation(500120583gmouse times 4) showed that both NPs induced lunginflammation and decreased pulmonary immune responsesagainst sheep erythrocytes In another study intravenouslyadministration of iron oxide NPs (587 nm) in doses le 10mgironkg shifted the Th1Th2 immunobalance towards theTh2-dominant direction and suppressed the delayed-typehypersensitivity in OVA-sensitized mice [44] Furthermorerepeated instillations resulted in a reduction of inflammationthan single instillation [88]

316 CeO2NPs Due to their reducibility cerium oxide NPs

(nanoceria) were found to have the ability to reduce ROSandmay be used as a novel therapeutic tool for inflammationtreatment [73] Some in vitro studies indicated that nanoceriawith a small diameter caused a significant anti-inflammatoryeffect [73 89 90] For example nanoceria with a diameterof 3ndash5 nm scavenged free radicals inhibited inflammatorymediator production in J774A1 the murine macrophages[73] A recent study reported that the same size of nanoceriainducedAPCs to secrete IL-10 and induced aTh2-dominatedT cell proliferation The nanoceria (5ndash8 nm) showed aneffective antioxidant property in cardiac progenitor cells andprotected the cardiac progenitor cells from H

2O2-induced

cytotoxicity In addition in vivo investigation on immunecells of the sea urchin indicated that nanoceria suppressed theinnate immunity when force-fed 1mL 10minus2 gL 50ndash60 nm ofnanoceria [91]

317 Quantum Dots As efficient energy donors [92] QDscan induce the generation of ROS by transferring energyto nearby oxygen molecules In vitro studies have shownthat QDs induced production of ROS and led to multipleorganelle damage and cell death [93 94] Preexposure toa dose at 10minus7 to 10minus3 120583gmL CdTe QDs suppressed theimmune responses of J774A1 macrophage to bacteria byreducing NO TNF-120572 KCCXCL-1 and IL-8 production[95] These in vitro studies suggested that QDs might havehigh immunotoxicity In vivo studies also showed similarresults CdTe QDs (16 4 and 8mgL for 24 h at 15∘C)significantly decreased the viability of hemocytes as wellas number of hemocytes capable of ingesting fluorescentbeads in Elliption complanata mussels [50] The immuno-suppression was also observed in Juvenile rainbow troutWhen 5 10 and 20 nM CdSCdTe QDs were exposed toJuvenile rainbow trout for 96 h at 15∘C the leukocyte countsviability and both resting and active phagocytic activity weresignificantly reduced [51] QDs affected the proliferation ofimmune cells but did not induce immune response includingcytokine production [96] Size of QDs aggregates may affect

the immune response of QDs Large CdSCdTe QDs aggre-gates (25ndash100 nm) reduced phagocytosis more than smallerNPs (lt25 nm) on bivalves (Mytilus edulis and Elliptio com-planata) and fish (Oncorhynchus mykiss) [97] Thereforecaution is needed to overcome this barrier when QDs areapplied in clinical treatment

318 Polymeric NPs In vivo studies indicated that somepolymeric NPs inhibited inflammation but had no effect onhost immunity [54 98] NPs produced by particle replicationin nonwetting template technology remained in the lungs forup to 7 days without triggering host immunity after intra-tracheal administration of 50 120583gmouse [98] PolystyreneNPs (50 nm) inhibited lung inflammation by intratrachealadministration of 200120583gmouse after allergen challengeThisinhibition was due to the modulation of DCs functions NPsinhibited expansion of CD11c+MHCIIhi DCs in the lungs anddraining lymph node and allergen-laden CD11bhiMHCIIhiDCs in the lungs [54] In addition polystyrene particles havethe potential to halt the disease process in autoimmunityFor example antigen-decorated polystyrene particles with adiameter of 500 nm induced T-cell tolerance and amelioratedexperimental autoimmune encephalomyelitis by inactivatingpathogenic T cells [55]

32 Immunostimulation

321 CarbonNanotubes CNTs induced immunostimulationin vitro and in vivo The oropharyngeal aspiration of MWC-NTs (1 2 and 4mgkg) in C57BL6 mice induced inflam-mation (30 days postinstillation) in lungs [20 21] MWCNTswere translocated progressively into the spleen reached amaximumof 48 h after intraperitoneally (ip) administrationwhich caused the lymphocytic hyperplasia and increasedoxidative stress in the spleen [99] Subcutaneous adminis-tration of MWCNTs with total dose of 10mg for two scinjections in BALBc mice induced acute immunologicalreactions for 1 week (activation of complement and increasedproinflammatory cytokines) However the accumulation ofMWCNTs and injury was not observed in spleen [24]MWC-NTs injected intravenously activated Th2 immune responseby elevating Th2 cytokines and increasing number of CD4+and CD8+ T cell in the spleen [23] In other studies CNTsshowed allergy adjuvant effect in inflammatory mass Forexample SWCNTs andMWCNTs exhibited adjuvant activityto the OVA-sensitized mice [25 100] MWCNTs aggravatedasthma and induced fibrosis in OVA-sensitized lungs butshowed no response with healthy pulmonary The resultsindicated that these NPs could bring harm to asthma patientsbut not health ones [25] In recent in vitro studies MWCNTsincreased the release of a series of cytokines in peripheralblood mononuclear cells (PBMCs) from healthy donorsafter stimulation with toll-like receptor (TLR) agonists orT cell mitogen However MWCNTs suppressed immuneresponses in PBMCs frommite-allergic subjects These stud-ies suggest that MWCNTs may either stimulate or suppressimmune system depending on their immune cell target[101]

322 Graphene GO could induce healthy DCs to differen-tion and maturation at varying degrees [102] but suppressthe antigen-delivering ability of OVA-loaded DCs to Tlymphocytes [103]This inhibitionwas associatedwith down-regulation of subunit LMP7 of immunoproteasome in cellswhich is responsible for antigens processing in DCs [103]Whenmacrophage cells RAW2647 were incubated with GOtoll-like receptor (TLR4TLR9-) 6 modulated autophagy andinflammatory responses occurred [104] In addition PVP-coated GO exhibited lower immunogenicity than GO on theaspect of inducing maturation and differentiation of DCs[102] PVP-coated GO enhanced the physiological activityof macrophages which showed anti-phagocytosis abilityagainst macrophages and delayed the apoptotic process ofT lymphocytes [102] This advantage makes PVP-coated GOa promising candidate of immunoadjuvant The effect oftwo sizes (2120583m and 350 nm) of the GO in response tomicrophages was investigated [105] These two NPs hadequal uptake amount in macrophages but microsized GOinduced stronger inflammation responses and showed diver-gent intracellular locations compared to nanosized GO [105]This result demonstrated that lateral dimension of GO playsan important role in the regulation of cellular responsesRecent studies demonstrated that intravenously deliveredgraphene nanosheets induced site-specificTh2 inflammatoryresponses in the lungs via the IL-33ST2 axis [23] Thiseffect may cause host defense and exacerbation of allergicdiseases However more studies in vivo are needed to assessand eliminate the potential immunomodulation of graphene-based materials to ensure their safety for applications inbiomedicine

323 Fullerene Some studies showed that C60have immun-

ostimulatory properties [28ndash30 103 106] After instillationC60upregulated gene expression of various proinflammatory

cytokines (IL-1 TNF-120572 IL-6) andTh1 cytokines (IL-12 IFN-120574) in mice Besides inflammation C

60could activate the

immune system The carboxyfullerene could prolong theinfiltrating neutrophils to enhance the bactericidal activity ofneutrophils [30] Other studies indicated that fullerene mayenhance the ability of DCs to stimulate T cells and further-more activated cells of innate immune system by enhancingproduction of IL-6 and an activation of natural killer (NK)cells [103 106] In addition immunization of mice with aC60

fullerene derivative conjugated to bovine thyroglobulincould produce a population of fullerene-specific antibodieswhich included a subpopulation that cross-reacted with a C

324 Gold NPs GNPs with different surface modifica-tion showed different immunogenicity in organisms Theimmunogenicity of GNPs coated with C-terminal 19 kDafragment of merozoite surface protein 1 (MSP-1

19) was an

important vaccine candidate In this study GNPs showedpoor immunogenicity in mice but enhanced antibodyresponse when formulated with alum [15] However GNPscoated with monosaccharide or disaccharides could initiatethe immune response by activating the macrophages [107]

Some studies indicated that high concentrations of PEGcoated on GNPs could induce antibody production andtrigger immune responses High doses of injected PEG-coated GNPs were cleared through these mechanisms [3233]

GNPs can also induce inflammatory responses in vivoWell-dispersed PEG-coated GNPs (13 nm) can be recognizedby host defense mechanism and induce acute inflammationand apoptosis in the liver [34] If inflamed tissues are exposedstronger immune responses may be induced [108] Whenexposed to sensitized mice 40 nm GNPs could lead to athreefold increase in airway hyperreactivity and increase thenumber of neutrophils and macrophages [36]

325 Silver NPs Intratracheal instillation of AgNPs with adiameter of 5225 plusmn 2364 nm could enhance the respiratoryimmune function through oxidative stress and inducedinflammation in the respiratoryWhen alveolar macrophageswere activated by AgNPs to cause phagocytosis the alve-olar macrophages generated ROS and free radicals whichresulted in oxidative stress The normal function of alveolarmacrophages and epithelial cells was subsequently affectedThis led to oversecretion of cytokines and oxides which thencaused the stimulation of the respiratory immune function[40] These opposite results may be due to the differentdiameters of NPs Covalent conjugation of Ag to solid corenanobeads with different diameters ranging from 002 to2 120583m was found localized into DCs (DEC205+ CD40+CD86+) in draining lymph nodes and induced high levels ofIFN-120574 production and high antibody titers in tumor-bearingmice [41]

326 CeO2NPs Instillation of 100 120583g nanoceria with a

diameter of 8 nm in C57BL6 mice revealed that the NPsinduced inflammation in pulmonary system by activatingMCs [46] Other studies using bigger sizes showed the sameeffect Single intratracheal instillation of 20 nm nanoceriaat 015ndash7mgkg caused a dose-dependent inflammation andlung injury [47] The intratracheal instillation of 20ndash30 nmnanoceria (241m2g) with doses of 50 and 150 cm2mouseinduced both acute and chronic neutrophilicmildly cyto-toxic inflammation [48] Inhalation of 55 nm nanoceriawith an average aerosol concentration of 641mgm3 for 4 hinduced cytotoxicity via oxidative stress and led to a chronicinflammatory response including up regulation of IL-1120573TNF-120572 and IL-6 [49]

327 Silica NPs 30 nm amorphous silica NPs were inves-tigated in PBMCs and purified monocytes These NPscould induce inflammatory response as production of IL-1120573 IL-8 and ROS This result indicated the potential ofsilica NPs to evoke innate immune reactions [109] Otherreports showed that 30 and 70 nm silica NPs inducedhigher production of TNF-120572 in RAW2647 cells and strongerinflammatory responses (IL-5uarr IL-6uarr MCP-1uarr keratinocytechemoattractantuarr) than 300 and 1000 nm particles in vivo

through intraperitoneally injection The 70 nm particle-induced TNF-120572 production was dependent on the produc-tion of ROS and activation of mitogen activated proteinkinases (MAPKs) However modification of carboxyl groupson 70 nmparticles dramatically suppressed the inflammatoryresponses [52] As well Kupffer cells stimulated by 15 nmsilica NPs released large amounts of ROS TNF-120572 and NOThe viability of Buffalo rat liver (BRL) cells was reduced aftercultured with silica NP-stimulated Kupffer cells The authorsalso studied the intravenous injections of silica NPs with asingle dose of 50mgkg It caused hepatic inflammation andoxidative stress [53]

328 Polymeric NPs Polymer-based NPs were shown to beeffective adjuvants in vaccination [72 110 111] These poly-mers have the ability to activate cellular immune responsesin the host [112] For example N-trimethyl chitosan-mono-N-carboxymethyl chitosan (TMCMCC) NPs appeared tobe very promising as an adjuvant and delivery system forantigens Intranasal vaccination with tetanus toxoid loadedTMCMCC NPs (2835 plusmn 25 nm) was shown to induceboth the mucosal and systemic immune response (enhancedantibody response) The enhanced immunoglobulin G (IgG)immune response could be explained by the sustained releaseof the toxoid [113]

Some polymer NPs were reported to activate immunesystem through modulating the activation and capabilityof immune cells such as dendritic cells and T cells [114ndash116] Amphiphilic NPs possessed pathogen-mimicking prop-erties by activating DCs similar to lipopolysaccharide (LPS)thus it has the ability to activate innate immune response[114] Poly(methyl vinyl ether-co-maleic anhydride) NPs(149 plusmn 2 nm) activated DCs through TLR stimulation ininnate immune system [115] As well the sulfonate (245 nm)and phosphonate-functionalized (227 nm) polystyrene NPsinduced the maturation of immature DCs and significantlyenhancedT cells stimulatory capacity indicating a shift toTh1response [116]

329 Other NPs Dendrimers have the ability to stimu-late immune system and can be used as potential candi-dates for vaccines [76] Maltose-functionalized dendrimer-peptide complex is a potential DC-based vaccine candi-date by stimulating DC and activating the immune system[117] Research also showed that Pan-DR-binding epitope-derivatized-dendrimer could reduce the effective dose ofliposomal amphotericin B inmurine cutaneous leishmaniasisand enhance adaptive immunity by activating strong parasitespecific T-cell responses [56]

Protein NPs have shown immunostimulating propertiesin recent studies [118ndash120] Self-assembled protein NPs thatdisplayed epitopes of the repeat sequence in circumsporo-zoite protein of plasmodium falciparum (PfCSP) elicited astrong immune response against PfCSP [119 121] In additionprotein NPs mimic viruses have the ability to facilitate DCsactivation and cross-presentationThese proteinNPs codeliv-ered with peptide epitopes to DCs showed an increased andprolonged CD8+ T cell activation [120]

A lipidNPwas investigated in aDNAvaccine applicationThis NP which decorated with stearyl-conjugated KALAan 120572-helical peptide (sequence WEAKLAKALAKALAK-HLAKALAKALKACEA) showed enhancement of transgeneexpression this enhancement was closely related to immune-activation [122] A cationic solid-lipid NP was used as a vac-cine to deliver a DNA vaccine against visceral leishmaniasisHigh levels of IFN-120574 and low levels of IL-10 production weredetected in BALBc mice after administration of the DNAvaccine delivered by this cationic solid-lipid NP This NPinduced a strongTh1 immune response indicating its poten-tial as therapeutic agent against visceral leishmaniasis [57]Nanolipoprotein conjugated with TLR agonists monophos-phoryl lipid A or CpG oligodeoxynucleotides significantlyenhanced the immunostimulatory profiles compared to theagonists alone Moreover the BALBc mice pretreated withCpGnanolipoprotein coloaded nanoconstructs but not CpGalone survived a lethal influenza challenge [58] Researchalso indicated that intravenous injection of liposome-DNAcomplexes elicited production of IFN-120572 and IFN-120573 in vivowhich suggested that the liposome-DNA complexes caninduce inflammation and cause systemic toxicity [123] Inanother study it was reported that Doxil an PEGylatedliposomal formulation of doxorubicin may cause hyper-sensitivity reactions while the standard doxorubicin didnot indicating that liposomes might be responsible for thishypersensitivity [59] It was speculated that the complementsystem activation by Doxil may play a key role in this effect[59]

4 The Factors Affecting Immunomodulationof NPs

Many factors contribute to immunomodulation of NPs Thenature of NPs such as composition surface chemistry sizeshape and protein-binding ability dominates these interac-tions Besides individual difference and exposure route alsocontribute to immunomodulation of NPs

41 Composition Composition of NPs lays a vital role inthe interactions between NPs and immune system Forexample QDs showed high immunotoxicity [50 51] becausethey release heavy metal ions Some other NPs exhibit lessimmunotoxicity [17 23 39 44 54] immunogenic [15 32]or no effect [45] The different core of NPs gave differentreaction in allergy mass For example CNTs and GNPsshowed adjuvant effect and led to hypersensitivity in theseallergy masses [25 26 36] while fullerene often showedimmunosuppression [14 31]

42 Surface Chemistry For NPs with the same compositionsurface properties may also affect the immune system Engi-neered NPs such as CNTs fullerenes GNPs and silica NPscan be modified with diverse surface chemistry This mayalter their immune response both in vitro and in vivo

Eighty diversely functionalized multiwall nanotube(MWNT) induced different levels of protein bindingcytotoxicity and immune responses (Figure 2) [124] The

modification of MWCNTs significantly alleviated nuclearfactor kappa B (NF-120581B) activation and reduced immuno-toxicity ofMWCNTs in BALBcmice [125] Carboxyfullereneactivated immune system of C57BL6 mice by prolongingthe infiltrating neutrophils to enhance the bactericidalactivity of neutrophils [30] while hydroxylated fullerenesinterferedwith the innate immune system in fatheadminnow[31] MWCNTs-PEG induced less generation of ROS andcytotoxicity in macrophages than MWCNTs-COOH whichwas in correspondence with the lower cellular uptake ofMWCNTs-PEG [126] The monolayer-protected GNPs invivo were studied Simple place-exchange reactions withinthe monolayer by short chain mercaptotetraethylene glycolhave been used The short chain at lower concentrations didnot trigger the immune system to produce anti-PEG antibody[33] However high concentration mixed monolayer coatedNPs initiated an immune response [32] Silica NPs (70 nm)induced strong inflammation by intraperitoneal injectionbut these inflammatory responses could be dramaticallysuppressed by surface modification by carboxyl groups [52]The toxicity of porous silica NPs to immune cells was surfacechemistry and surface charge-dependent Compare tosurface hydrophobicity surface charge had stronger impacton NPsrsquo immunotoxicity in vitro and in vivo Positivelycharged hydrophobic NPs showed more DNA damage thannegatively charged hydrophilic NPs [127]

43 Size Size is another important parameter that deter-mines the interaction with organisms When examinedimmunity is induced by a series of differentially sized (2040 49 67 93 101 and 123 nm) polystyrene nanobeads IFN-120574 induction from CD8+ T cells was limited to 40 and 49 nmbeads while 93ndash123 nmbeads inducedCD4+ T cell activationand increased IL-4 levelThese results showed that the size ofnanobead for vaccination could influence the type 1type 2cytokine balance This would be useful in the developmentof vaccines against common human pathogens [128] 200 nmNPs increased more antigen-specific polyfunctional CD4+ Tcells as compared to 30 nm NPs The immunoactivity of dis-accharides coated GNPs is strongly dependent on size Theyused 2 and 5 nm GNPs coated with disaccharides These NPsactivated the macrophages and induced the proliferation of Tcells and the increase of IL-2 levels The 5 nmNPs performedfar better than 2 nmones (increasedAPC proliferationMHCII expression T cell proliferation and IL-2 expression) [107]Other researches indicated that single instillation (250 375or 500 120583gmouse) of 35 plusmn 14 nm iron oxide NPs inducedhigher levels of inflammation and immunodepression than147plusmn48 nm ones [88] Repeated intratracheal administrationof high dose (4 times 500120583gmouse) and intermediate dose (4 times250 120583gmouse) of the same NPs inhibited the allergic Th2-dominated response induced by OVA The low dose (4 times100 120583gmouse) of 147 plusmn 48 nm iron oxide particles had nosignificant effect but the low dose (4 times 100 120583gmouse) of 35plusmn14 nm particles had an adjuvant effect on theTh2 response toOVA [45] Aggregate size may also affect the immunotoxicityof QDs The toxicity of CdSCdTe QDs was size dependentLarge CdSCdTe QD aggregates (25 nmndash100 nm) reduced

44 Protein Binding When NPs enter the body throughinjection they firstly interact with blood [129] The plasmaprotein binding on the NPs surface such as apolipoprotein Eand transferrinmay contribute to the activationdeactivationof receptor-dependent signaling [130]

The amount and types of proteins adsorbed on the NPsaffect the interactions of cells and NPs and the biologicalresponses [131 132]The composition surface characteristicsand shape of NPs affect the manners that the proteinsbind to them [129 133ndash136] The blood proteins adsorbedonto the NPs include immunoglobulins apolipoproteins andproteins of the complement system among many othersThese proteins may act as signals for immune responses [137138] Furthermore NPs may induce conformational changesin the structure of adsorbed proteins Negatively chargedpoly(acrylic acid-) conjugated GNPs bound with fibrinogenand induced the unfolding of this protein which promotedinteraction with Mac-1 an integrin receptor This activationincreased the NF-120581B signalling pathway and released inflam-matory cytokines [139]

45 Exposure Route Exposure route is another factor affect-ing the immunomodulation ofNPsTheoutcomes of immuneresponse are dependent on entrance of NPs In the lungsDCs pulmonary epithelium and macrophages play animportant role in handling foreign materials In the bloodleukocyte such as neutrophil eosinophil basophil lympho-cyte and monocyte play a vital role Single intratrachealinstillation of 500120583gmouse iron oxide NPs (35 plusmn 14 nmand 147 plusmn 48 nm) induced lung inflammation and decreasedpulmonary immune responses against sheep erythrocytes[88] Pharyngeal aspiration of SWCNTs modified systemicimmunity by modulating DCs function [19] Intravenouslyadministration of iron oxide NPs (587 nm) could sup-press the infiltration and functional activity of Th1 cellsand macrophages [44] Intravenous injection of graphenenanosheets activated a Th2 immune response which con-sisted of neutrophilic influx and a significant increase inIL-5 IL-13 IL-33 in the bronchoalvelar lavage fluid [23]The dosage of administration is also important Intratrachealinjection of iron oxide NPs (35 plusmn 14 nm) inhibited theallergic response in OVA-sensitized mice at a dosage of 4 times250120583gmouse or 4 times 500 120583gmouse but showed adjuvanteffect at a dosage of 4 times 100 120583gmouse [45]

5 The Mechanisms of ImmunomodulationInduced by NPs

NPs interact with both innate and adaptive immune cellsaffect their functions and disturb immune system (Figure 3)

Inflammation is an important response of immune sys-tem which can be induced by NPs evidenced by the pro-duction of cytokines or chemokines Oxidative stress causedby NPs is reported to be the main downstream events ofthe inflammation NPs have large surface areas and strong

oxidative abilities than normal particles [140] Oxidativedamage induced by NPs is an important factor of immuneimbalance [11] Many types of NPs have been shown toproduce ROS in vitro and in vivo and enhance immunefunction or inflammatory response [40 49 53 86 141] Freeradical-induced tissue damage plays an important role ininflammatory diseases [142 143]

The signal pathway to induce ROS and mediate inflam-mation was reported Among them TLR4 signaling pathwaywas documented GO could induce intracellular ROS whichdecreased the viability of macrophages and induced necrosisby a TLR4 signaling pathway (Figure 4) [144] TLR is areceptor of the innate immune system and innate immunitycould be triggered by stimulating TLRs and lead to strongadaptive immunity [115] Activation of the TLR pathwayscould induce chronic inflammation and ROS [145] Resentresearch indicated that quantum dots could activate myeloiddifferentiation primary response gene 88 (MyD88 which isan adapter protein to activate NF-120581B) dependent-TLRs inmcrophages and activated NF-120581B [146]

NF-120581B pathway is another key regulator of immuneresponse [125 147ndash149] As an important regulator of proin-flammatory gene expression synthesis of cytokines suchas IL-1120573 IL-6 IL-8 and TNF-120572 is mediated by NF-120581B

Activation of NF-120581B may induce human inflammatory dis-eases [150 151] It was reported that negatively chargedpoly(acrylic acid-) conjugated GNP activated the NF-120581Bsignalling pathway in THP-1 cells The cells released inflam-matory cytokines including TNF-120572 and IL-8 [139] Andcitrate-stabilized 10 nm GNPs could induce activation of anNF-120581B regulated luciferase reporter in murine B-lymphocytecell line (CH12LX) and altered the cell function [152]

NPs may also disturb the immune balance by inappro-priate maturationactivation of APCs such as DCs [26 153]Intratracheal instillation of 43 nmMIONs the alveolar regionof BALBc mice could generate a significant number ofexosomes These exosomes were quickly eliminated from thealveolar region into systemic circulation and transferred theirsignals to the immune system which resulted in maturationof DCs and activation of splenic T cells and the exosome-induced T-cell activation is more efficient in OVA-sensitizedmice [42 43] Cytotoxicity to immune cells may contribute toimmunosuppression of NPs QDs may decrease the viabilityof hemocytes in Elliption complanata mussels [50] andreduced phagocytosis on bivalves and fish [97]

Recent reports indicated that NPs could modulate thehomeostasis of immune cells including the shift of Th1Th2balance [43 44 89] and monocyte homeostasis [154] Forexample magnetic iron oxide NPs activated the T cellsinduced a Th1 polarization and aggravated inflammation[43]Other studies showed that SWCNTs accentuatedThcellsimmunity includingTh2 (IL-4uarr IL-5uarr and IL-13uarr) andTh17

(IL-17Auarr IL-23uarr) The inappropriate maturationactivationof APCs such as DCs might be responsible for these accen-tuated Th cells immunity [26 153] The normal immunesystem keeps a Th1Th2 balance in order to achieve anappropriate immune response Selectively activating Th1 orTh2 cells results in immune deviation and breaks the balanceof immune system In addition MWCNTs could selectivelydecrease phagocytosis-competent monocytes and promoteadhesion of the phagocytosis-incompetent monocytes inblood flow [154]

6 Conclusion

The immune response of NPs is like a double-edged swordin nanomedicine applications by bringing both benefits andharms We should take advantage of the benefits from theimmunomodulating properties of NPs and on the otherhand avoid the undesirable immune responses in order tominimize the systemic side effects The factors affecting theimmune response are complex including particle compo-sition size surface chemistry plasma protein binding andexposure route Investigation of the relationship betweenproperties of NPs and systemic immune response is crucialfor their application in medicine and other areas Althoughtreatments of acute and long-term immune toxicities havebeen developed current approaches of prediction preven-tion and treatment of nanoimmunomodulation are stilllacking encouraging further in-depth studies

the immune response of QDs Large CdSCdTe QDs aggre-gates (25ndash100 nm) reduced phagocytosis more than smallerNPs (lt25 nm) on bivalves (Mytilus edulis and Elliptio com-planata) and fish (Oncorhynchus mykiss) [97] Thereforecaution is needed to overcome this barrier when QDs areapplied in clinical treatment

318 Polymeric NPs In vivo studies indicated that somepolymeric NPs inhibited inflammation but had no effect onhost immunity [54 98] NPs produced by particle replicationin nonwetting template technology remained in the lungs forup to 7 days without triggering host immunity after intra-tracheal administration of 50 120583gmouse [98] PolystyreneNPs (50 nm) inhibited lung inflammation by intratrachealadministration of 200120583gmouse after allergen challengeThisinhibition was due to the modulation of DCs functions NPsinhibited expansion of CD11c+MHCIIhi DCs in the lungs anddraining lymph node and allergen-laden CD11bhiMHCIIhiDCs in the lungs [54] In addition polystyrene particles havethe potential to halt the disease process in autoimmunityFor example antigen-decorated polystyrene particles with adiameter of 500 nm induced T-cell tolerance and amelioratedexperimental autoimmune encephalomyelitis by inactivatingpathogenic T cells [55]

32 Immunostimulation

321 CarbonNanotubes CNTs induced immunostimulationin vitro and in vivo The oropharyngeal aspiration of MWC-NTs (1 2 and 4mgkg) in C57BL6 mice induced inflam-mation (30 days postinstillation) in lungs [20 21] MWCNTswere translocated progressively into the spleen reached amaximumof 48 h after intraperitoneally (ip) administrationwhich caused the lymphocytic hyperplasia and increasedoxidative stress in the spleen [99] Subcutaneous adminis-tration of MWCNTs with total dose of 10mg for two scinjections in BALBc mice induced acute immunologicalreactions for 1 week (activation of complement and increasedproinflammatory cytokines) However the accumulation ofMWCNTs and injury was not observed in spleen [24]MWC-NTs injected intravenously activated Th2 immune responseby elevating Th2 cytokines and increasing number of CD4+and CD8+ T cell in the spleen [23] In other studies CNTsshowed allergy adjuvant effect in inflammatory mass Forexample SWCNTs andMWCNTs exhibited adjuvant activityto the OVA-sensitized mice [25 100] MWCNTs aggravatedasthma and induced fibrosis in OVA-sensitized lungs butshowed no response with healthy pulmonary The resultsindicated that these NPs could bring harm to asthma patientsbut not health ones [25] In recent in vitro studies MWCNTsincreased the release of a series of cytokines in peripheralblood mononuclear cells (PBMCs) from healthy donorsafter stimulation with toll-like receptor (TLR) agonists orT cell mitogen However MWCNTs suppressed immuneresponses in PBMCs frommite-allergic subjects These stud-ies suggest that MWCNTs may either stimulate or suppressimmune system depending on their immune cell target[101]

322 Graphene GO could induce healthy DCs to differen-tion and maturation at varying degrees [102] but suppressthe antigen-delivering ability of OVA-loaded DCs to Tlymphocytes [103]This inhibitionwas associatedwith down-regulation of subunit LMP7 of immunoproteasome in cellswhich is responsible for antigens processing in DCs [103]Whenmacrophage cells RAW2647 were incubated with GOtoll-like receptor (TLR4TLR9-) 6 modulated autophagy andinflammatory responses occurred [104] In addition PVP-coated GO exhibited lower immunogenicity than GO on theaspect of inducing maturation and differentiation of DCs[102] PVP-coated GO enhanced the physiological activityof macrophages which showed anti-phagocytosis abilityagainst macrophages and delayed the apoptotic process ofT lymphocytes [102] This advantage makes PVP-coated GOa promising candidate of immunoadjuvant The effect oftwo sizes (2120583m and 350 nm) of the GO in response tomicrophages was investigated [105] These two NPs hadequal uptake amount in macrophages but microsized GOinduced stronger inflammation responses and showed diver-gent intracellular locations compared to nanosized GO [105]This result demonstrated that lateral dimension of GO playsan important role in the regulation of cellular responsesRecent studies demonstrated that intravenously deliveredgraphene nanosheets induced site-specificTh2 inflammatoryresponses in the lungs via the IL-33ST2 axis [23] Thiseffect may cause host defense and exacerbation of allergicdiseases However more studies in vivo are needed to assessand eliminate the potential immunomodulation of graphene-based materials to ensure their safety for applications inbiomedicine

323 Fullerene Some studies showed that C60have immun-

ostimulatory properties [28ndash30 103 106] After instillationC60upregulated gene expression of various proinflammatory

cytokines (IL-1 TNF-120572 IL-6) andTh1 cytokines (IL-12 IFN-120574) in mice Besides inflammation C

60could activate the

immune system The carboxyfullerene could prolong theinfiltrating neutrophils to enhance the bactericidal activity ofneutrophils [30] Other studies indicated that fullerene mayenhance the ability of DCs to stimulate T cells and further-more activated cells of innate immune system by enhancingproduction of IL-6 and an activation of natural killer (NK)cells [103 106] In addition immunization of mice with aC60

fullerene derivative conjugated to bovine thyroglobulincould produce a population of fullerene-specific antibodieswhich included a subpopulation that cross-reacted with a C

70

fullerene [29]

324 Gold NPs GNPs with different surface modifica-tion showed different immunogenicity in organisms Theimmunogenicity of GNPs coated with C-terminal 19 kDafragment of merozoite surface protein 1 (MSP-1

19) was an

important vaccine candidate In this study GNPs showedpoor immunogenicity in mice but enhanced antibodyresponse when formulated with alum [15] However GNPscoated with monosaccharide or disaccharides could initiatethe immune response by activating the macrophages [107]

BioMed Research International 9

Some studies indicated that high concentrations of PEGcoated on GNPs could induce antibody production andtrigger immune responses High doses of injected PEG-coated GNPs were cleared through these mechanisms [3233]

GNPs can also induce inflammatory responses in vivoWell-dispersed PEG-coated GNPs (13 nm) can be recognizedby host defense mechanism and induce acute inflammationand apoptosis in the liver [34] If inflamed tissues are exposedstronger immune responses may be induced [108] Whenexposed to sensitized mice 40 nm GNPs could lead to athreefold increase in airway hyperreactivity and increase thenumber of neutrophils and macrophages [36]

325 Silver NPs Intratracheal instillation of AgNPs with adiameter of 5225 plusmn 2364 nm could enhance the respiratoryimmune function through oxidative stress and inducedinflammation in the respiratoryWhen alveolar macrophageswere activated by AgNPs to cause phagocytosis the alve-olar macrophages generated ROS and free radicals whichresulted in oxidative stress The normal function of alveolarmacrophages and epithelial cells was subsequently affectedThis led to oversecretion of cytokines and oxides which thencaused the stimulation of the respiratory immune function[40] These opposite results may be due to the differentdiameters of NPs Covalent conjugation of Ag to solid corenanobeads with different diameters ranging from 002 to2 120583m was found localized into DCs (DEC205+ CD40+CD86+) in draining lymph nodes and induced high levels ofIFN-120574 production and high antibody titers in tumor-bearingmice [41]

326 CeO2NPs Instillation of 100 120583g nanoceria with a

diameter of 8 nm in C57BL6 mice revealed that the NPsinduced inflammation in pulmonary system by activatingMCs [46] Other studies using bigger sizes showed the sameeffect Single intratracheal instillation of 20 nm nanoceriaat 015ndash7mgkg caused a dose-dependent inflammation andlung injury [47] The intratracheal instillation of 20ndash30 nmnanoceria (241m2g) with doses of 50 and 150 cm2mouseinduced both acute and chronic neutrophilicmildly cyto-toxic inflammation [48] Inhalation of 55 nm nanoceriawith an average aerosol concentration of 641mgm3 for 4 hinduced cytotoxicity via oxidative stress and led to a chronicinflammatory response including up regulation of IL-1120573TNF-120572 and IL-6 [49]

327 Silica NPs 30 nm amorphous silica NPs were inves-tigated in PBMCs and purified monocytes These NPscould induce inflammatory response as production of IL-1120573 IL-8 and ROS This result indicated the potential ofsilica NPs to evoke innate immune reactions [109] Otherreports showed that 30 and 70 nm silica NPs inducedhigher production of TNF-120572 in RAW2647 cells and strongerinflammatory responses (IL-5uarr IL-6uarr MCP-1uarr keratinocytechemoattractantuarr) than 300 and 1000 nm particles in vivo

through intraperitoneally injection The 70 nm particle-induced TNF-120572 production was dependent on the produc-tion of ROS and activation of mitogen activated proteinkinases (MAPKs) However modification of carboxyl groupson 70 nmparticles dramatically suppressed the inflammatoryresponses [52] As well Kupffer cells stimulated by 15 nmsilica NPs released large amounts of ROS TNF-120572 and NOThe viability of Buffalo rat liver (BRL) cells was reduced aftercultured with silica NP-stimulated Kupffer cells The authorsalso studied the intravenous injections of silica NPs with asingle dose of 50mgkg It caused hepatic inflammation andoxidative stress [53]

328 Polymeric NPs Polymer-based NPs were shown to beeffective adjuvants in vaccination [72 110 111] These poly-mers have the ability to activate cellular immune responsesin the host [112] For example N-trimethyl chitosan-mono-N-carboxymethyl chitosan (TMCMCC) NPs appeared tobe very promising as an adjuvant and delivery system forantigens Intranasal vaccination with tetanus toxoid loadedTMCMCC NPs (2835 plusmn 25 nm) was shown to induceboth the mucosal and systemic immune response (enhancedantibody response) The enhanced immunoglobulin G (IgG)immune response could be explained by the sustained releaseof the toxoid [113]

Some polymer NPs were reported to activate immunesystem through modulating the activation and capabilityof immune cells such as dendritic cells and T cells [114ndash116] Amphiphilic NPs possessed pathogen-mimicking prop-erties by activating DCs similar to lipopolysaccharide (LPS)thus it has the ability to activate innate immune response[114] Poly(methyl vinyl ether-co-maleic anhydride) NPs(149 plusmn 2 nm) activated DCs through TLR stimulation ininnate immune system [115] As well the sulfonate (245 nm)and phosphonate-functionalized (227 nm) polystyrene NPsinduced the maturation of immature DCs and significantlyenhancedT cells stimulatory capacity indicating a shift toTh1response [116]

329 Other NPs Dendrimers have the ability to stimu-late immune system and can be used as potential candi-dates for vaccines [76] Maltose-functionalized dendrimer-peptide complex is a potential DC-based vaccine candi-date by stimulating DC and activating the immune system[117] Research also showed that Pan-DR-binding epitope-derivatized-dendrimer could reduce the effective dose ofliposomal amphotericin B inmurine cutaneous leishmaniasisand enhance adaptive immunity by activating strong parasitespecific T-cell responses [56]

Protein NPs have shown immunostimulating propertiesin recent studies [118ndash120] Self-assembled protein NPs thatdisplayed epitopes of the repeat sequence in circumsporo-zoite protein of plasmodium falciparum (PfCSP) elicited astrong immune response against PfCSP [119 121] In additionprotein NPs mimic viruses have the ability to facilitate DCsactivation and cross-presentationThese proteinNPs codeliv-ered with peptide epitopes to DCs showed an increased andprolonged CD8+ T cell activation [120]

A lipidNPwas investigated in aDNAvaccine applicationThis NP which decorated with stearyl-conjugated KALAan 120572-helical peptide (sequence WEAKLAKALAKALAK-HLAKALAKALKACEA) showed enhancement of transgeneexpression this enhancement was closely related to immune-activation [122] A cationic solid-lipid NP was used as a vac-cine to deliver a DNA vaccine against visceral leishmaniasisHigh levels of IFN-120574 and low levels of IL-10 production weredetected in BALBc mice after administration of the DNAvaccine delivered by this cationic solid-lipid NP This NPinduced a strongTh1 immune response indicating its poten-tial as therapeutic agent against visceral leishmaniasis [57]Nanolipoprotein conjugated with TLR agonists monophos-phoryl lipid A or CpG oligodeoxynucleotides significantlyenhanced the immunostimulatory profiles compared to theagonists alone Moreover the BALBc mice pretreated withCpGnanolipoprotein coloaded nanoconstructs but not CpGalone survived a lethal influenza challenge [58] Researchalso indicated that intravenous injection of liposome-DNAcomplexes elicited production of IFN-120572 and IFN-120573 in vivowhich suggested that the liposome-DNA complexes caninduce inflammation and cause systemic toxicity [123] Inanother study it was reported that Doxil an PEGylatedliposomal formulation of doxorubicin may cause hyper-sensitivity reactions while the standard doxorubicin didnot indicating that liposomes might be responsible for thishypersensitivity [59] It was speculated that the complementsystem activation by Doxil may play a key role in this effect[59]

4 The Factors Affecting Immunomodulationof NPs

Many factors contribute to immunomodulation of NPs Thenature of NPs such as composition surface chemistry sizeshape and protein-binding ability dominates these interac-tions Besides individual difference and exposure route alsocontribute to immunomodulation of NPs

41 Composition Composition of NPs lays a vital role inthe interactions between NPs and immune system Forexample QDs showed high immunotoxicity [50 51] becausethey release heavy metal ions Some other NPs exhibit lessimmunotoxicity [17 23 39 44 54] immunogenic [15 32]or no effect [45] The different core of NPs gave differentreaction in allergy mass For example CNTs and GNPsshowed adjuvant effect and led to hypersensitivity in theseallergy masses [25 26 36] while fullerene often showedimmunosuppression [14 31]

42 Surface Chemistry For NPs with the same compositionsurface properties may also affect the immune system Engi-neered NPs such as CNTs fullerenes GNPs and silica NPscan be modified with diverse surface chemistry This mayalter their immune response both in vitro and in vivo

Eighty diversely functionalized multiwall nanotube(MWNT) induced different levels of protein bindingcytotoxicity and immune responses (Figure 2) [124] The

modification of MWCNTs significantly alleviated nuclearfactor kappa B (NF-120581B) activation and reduced immuno-toxicity ofMWCNTs in BALBcmice [125] Carboxyfullereneactivated immune system of C57BL6 mice by prolongingthe infiltrating neutrophils to enhance the bactericidalactivity of neutrophils [30] while hydroxylated fullerenesinterferedwith the innate immune system in fatheadminnow[31] MWCNTs-PEG induced less generation of ROS andcytotoxicity in macrophages than MWCNTs-COOH whichwas in correspondence with the lower cellular uptake ofMWCNTs-PEG [126] The monolayer-protected GNPs invivo were studied Simple place-exchange reactions withinthe monolayer by short chain mercaptotetraethylene glycolhave been used The short chain at lower concentrations didnot trigger the immune system to produce anti-PEG antibody[33] However high concentration mixed monolayer coatedNPs initiated an immune response [32] Silica NPs (70 nm)induced strong inflammation by intraperitoneal injectionbut these inflammatory responses could be dramaticallysuppressed by surface modification by carboxyl groups [52]The toxicity of porous silica NPs to immune cells was surfacechemistry and surface charge-dependent Compare tosurface hydrophobicity surface charge had stronger impacton NPsrsquo immunotoxicity in vitro and in vivo Positivelycharged hydrophobic NPs showed more DNA damage thannegatively charged hydrophilic NPs [127]

43 Size Size is another important parameter that deter-mines the interaction with organisms When examinedimmunity is induced by a series of differentially sized (2040 49 67 93 101 and 123 nm) polystyrene nanobeads IFN-120574 induction from CD8+ T cells was limited to 40 and 49 nmbeads while 93ndash123 nmbeads inducedCD4+ T cell activationand increased IL-4 levelThese results showed that the size ofnanobead for vaccination could influence the type 1type 2cytokine balance This would be useful in the developmentof vaccines against common human pathogens [128] 200 nmNPs increased more antigen-specific polyfunctional CD4+ Tcells as compared to 30 nm NPs The immunoactivity of dis-accharides coated GNPs is strongly dependent on size Theyused 2 and 5 nm GNPs coated with disaccharides These NPsactivated the macrophages and induced the proliferation of Tcells and the increase of IL-2 levels The 5 nmNPs performedfar better than 2 nmones (increasedAPC proliferationMHCII expression T cell proliferation and IL-2 expression) [107]Other researches indicated that single instillation (250 375or 500 120583gmouse) of 35 plusmn 14 nm iron oxide NPs inducedhigher levels of inflammation and immunodepression than147plusmn48 nm ones [88] Repeated intratracheal administrationof high dose (4 times 500120583gmouse) and intermediate dose (4 times250 120583gmouse) of the same NPs inhibited the allergic Th2-dominated response induced by OVA The low dose (4 times100 120583gmouse) of 147 plusmn 48 nm iron oxide particles had nosignificant effect but the low dose (4 times 100 120583gmouse) of 35plusmn14 nm particles had an adjuvant effect on theTh2 response toOVA [45] Aggregate size may also affect the immunotoxicityof QDs The toxicity of CdSCdTe QDs was size dependentLarge CdSCdTe QD aggregates (25 nmndash100 nm) reduced

44 Protein Binding When NPs enter the body throughinjection they firstly interact with blood [129] The plasmaprotein binding on the NPs surface such as apolipoprotein Eand transferrinmay contribute to the activationdeactivationof receptor-dependent signaling [130]

The amount and types of proteins adsorbed on the NPsaffect the interactions of cells and NPs and the biologicalresponses [131 132]The composition surface characteristicsand shape of NPs affect the manners that the proteinsbind to them [129 133ndash136] The blood proteins adsorbedonto the NPs include immunoglobulins apolipoproteins andproteins of the complement system among many othersThese proteins may act as signals for immune responses [137138] Furthermore NPs may induce conformational changesin the structure of adsorbed proteins Negatively chargedpoly(acrylic acid-) conjugated GNPs bound with fibrinogenand induced the unfolding of this protein which promotedinteraction with Mac-1 an integrin receptor This activationincreased the NF-120581B signalling pathway and released inflam-matory cytokines [139]

45 Exposure Route Exposure route is another factor affect-ing the immunomodulation ofNPsTheoutcomes of immuneresponse are dependent on entrance of NPs In the lungsDCs pulmonary epithelium and macrophages play animportant role in handling foreign materials In the bloodleukocyte such as neutrophil eosinophil basophil lympho-cyte and monocyte play a vital role Single intratrachealinstillation of 500120583gmouse iron oxide NPs (35 plusmn 14 nmand 147 plusmn 48 nm) induced lung inflammation and decreasedpulmonary immune responses against sheep erythrocytes[88] Pharyngeal aspiration of SWCNTs modified systemicimmunity by modulating DCs function [19] Intravenouslyadministration of iron oxide NPs (587 nm) could sup-press the infiltration and functional activity of Th1 cellsand macrophages [44] Intravenous injection of graphenenanosheets activated a Th2 immune response which con-sisted of neutrophilic influx and a significant increase inIL-5 IL-13 IL-33 in the bronchoalvelar lavage fluid [23]The dosage of administration is also important Intratrachealinjection of iron oxide NPs (35 plusmn 14 nm) inhibited theallergic response in OVA-sensitized mice at a dosage of 4 times250120583gmouse or 4 times 500 120583gmouse but showed adjuvanteffect at a dosage of 4 times 100 120583gmouse [45]

5 The Mechanisms of ImmunomodulationInduced by NPs

NPs interact with both innate and adaptive immune cellsaffect their functions and disturb immune system (Figure 3)

Inflammation is an important response of immune sys-tem which can be induced by NPs evidenced by the pro-duction of cytokines or chemokines Oxidative stress causedby NPs is reported to be the main downstream events ofthe inflammation NPs have large surface areas and strong

oxidative abilities than normal particles [140] Oxidativedamage induced by NPs is an important factor of immuneimbalance [11] Many types of NPs have been shown toproduce ROS in vitro and in vivo and enhance immunefunction or inflammatory response [40 49 53 86 141] Freeradical-induced tissue damage plays an important role ininflammatory diseases [142 143]

The signal pathway to induce ROS and mediate inflam-mation was reported Among them TLR4 signaling pathwaywas documented GO could induce intracellular ROS whichdecreased the viability of macrophages and induced necrosisby a TLR4 signaling pathway (Figure 4) [144] TLR is areceptor of the innate immune system and innate immunitycould be triggered by stimulating TLRs and lead to strongadaptive immunity [115] Activation of the TLR pathwayscould induce chronic inflammation and ROS [145] Resentresearch indicated that quantum dots could activate myeloiddifferentiation primary response gene 88 (MyD88 which isan adapter protein to activate NF-120581B) dependent-TLRs inmcrophages and activated NF-120581B [146]

NF-120581B pathway is another key regulator of immuneresponse [125 147ndash149] As an important regulator of proin-flammatory gene expression synthesis of cytokines suchas IL-1120573 IL-6 IL-8 and TNF-120572 is mediated by NF-120581B

Activation of NF-120581B may induce human inflammatory dis-eases [150 151] It was reported that negatively chargedpoly(acrylic acid-) conjugated GNP activated the NF-120581Bsignalling pathway in THP-1 cells The cells released inflam-matory cytokines including TNF-120572 and IL-8 [139] Andcitrate-stabilized 10 nm GNPs could induce activation of anNF-120581B regulated luciferase reporter in murine B-lymphocytecell line (CH12LX) and altered the cell function [152]

NPs may also disturb the immune balance by inappro-priate maturationactivation of APCs such as DCs [26 153]Intratracheal instillation of 43 nmMIONs the alveolar regionof BALBc mice could generate a significant number ofexosomes These exosomes were quickly eliminated from thealveolar region into systemic circulation and transferred theirsignals to the immune system which resulted in maturationof DCs and activation of splenic T cells and the exosome-induced T-cell activation is more efficient in OVA-sensitizedmice [42 43] Cytotoxicity to immune cells may contribute toimmunosuppression of NPs QDs may decrease the viabilityof hemocytes in Elliption complanata mussels [50] andreduced phagocytosis on bivalves and fish [97]

Recent reports indicated that NPs could modulate thehomeostasis of immune cells including the shift of Th1Th2balance [43 44 89] and monocyte homeostasis [154] Forexample magnetic iron oxide NPs activated the T cellsinduced a Th1 polarization and aggravated inflammation[43]Other studies showed that SWCNTs accentuatedThcellsimmunity includingTh2 (IL-4uarr IL-5uarr and IL-13uarr) andTh17

(IL-17Auarr IL-23uarr) The inappropriate maturationactivationof APCs such as DCs might be responsible for these accen-tuated Th cells immunity [26 153] The normal immunesystem keeps a Th1Th2 balance in order to achieve anappropriate immune response Selectively activating Th1 orTh2 cells results in immune deviation and breaks the balanceof immune system In addition MWCNTs could selectivelydecrease phagocytosis-competent monocytes and promoteadhesion of the phagocytosis-incompetent monocytes inblood flow [154]

6 Conclusion

The immune response of NPs is like a double-edged swordin nanomedicine applications by bringing both benefits andharms We should take advantage of the benefits from theimmunomodulating properties of NPs and on the otherhand avoid the undesirable immune responses in order tominimize the systemic side effects The factors affecting theimmune response are complex including particle compo-sition size surface chemistry plasma protein binding andexposure route Investigation of the relationship betweenproperties of NPs and systemic immune response is crucialfor their application in medicine and other areas Althoughtreatments of acute and long-term immune toxicities havebeen developed current approaches of prediction preven-tion and treatment of nanoimmunomodulation are stilllacking encouraging further in-depth studies

Some studies indicated that high concentrations of PEGcoated on GNPs could induce antibody production andtrigger immune responses High doses of injected PEG-coated GNPs were cleared through these mechanisms [3233]

GNPs can also induce inflammatory responses in vivoWell-dispersed PEG-coated GNPs (13 nm) can be recognizedby host defense mechanism and induce acute inflammationand apoptosis in the liver [34] If inflamed tissues are exposedstronger immune responses may be induced [108] Whenexposed to sensitized mice 40 nm GNPs could lead to athreefold increase in airway hyperreactivity and increase thenumber of neutrophils and macrophages [36]

325 Silver NPs Intratracheal instillation of AgNPs with adiameter of 5225 plusmn 2364 nm could enhance the respiratoryimmune function through oxidative stress and inducedinflammation in the respiratoryWhen alveolar macrophageswere activated by AgNPs to cause phagocytosis the alve-olar macrophages generated ROS and free radicals whichresulted in oxidative stress The normal function of alveolarmacrophages and epithelial cells was subsequently affectedThis led to oversecretion of cytokines and oxides which thencaused the stimulation of the respiratory immune function[40] These opposite results may be due to the differentdiameters of NPs Covalent conjugation of Ag to solid corenanobeads with different diameters ranging from 002 to2 120583m was found localized into DCs (DEC205+ CD40+CD86+) in draining lymph nodes and induced high levels ofIFN-120574 production and high antibody titers in tumor-bearingmice [41]

326 CeO2NPs Instillation of 100 120583g nanoceria with a

diameter of 8 nm in C57BL6 mice revealed that the NPsinduced inflammation in pulmonary system by activatingMCs [46] Other studies using bigger sizes showed the sameeffect Single intratracheal instillation of 20 nm nanoceriaat 015ndash7mgkg caused a dose-dependent inflammation andlung injury [47] The intratracheal instillation of 20ndash30 nmnanoceria (241m2g) with doses of 50 and 150 cm2mouseinduced both acute and chronic neutrophilicmildly cyto-toxic inflammation [48] Inhalation of 55 nm nanoceriawith an average aerosol concentration of 641mgm3 for 4 hinduced cytotoxicity via oxidative stress and led to a chronicinflammatory response including up regulation of IL-1120573TNF-120572 and IL-6 [49]

327 Silica NPs 30 nm amorphous silica NPs were inves-tigated in PBMCs and purified monocytes These NPscould induce inflammatory response as production of IL-1120573 IL-8 and ROS This result indicated the potential ofsilica NPs to evoke innate immune reactions [109] Otherreports showed that 30 and 70 nm silica NPs inducedhigher production of TNF-120572 in RAW2647 cells and strongerinflammatory responses (IL-5uarr IL-6uarr MCP-1uarr keratinocytechemoattractantuarr) than 300 and 1000 nm particles in vivo

through intraperitoneally injection The 70 nm particle-induced TNF-120572 production was dependent on the produc-tion of ROS and activation of mitogen activated proteinkinases (MAPKs) However modification of carboxyl groupson 70 nmparticles dramatically suppressed the inflammatoryresponses [52] As well Kupffer cells stimulated by 15 nmsilica NPs released large amounts of ROS TNF-120572 and NOThe viability of Buffalo rat liver (BRL) cells was reduced aftercultured with silica NP-stimulated Kupffer cells The authorsalso studied the intravenous injections of silica NPs with asingle dose of 50mgkg It caused hepatic inflammation andoxidative stress [53]

328 Polymeric NPs Polymer-based NPs were shown to beeffective adjuvants in vaccination [72 110 111] These poly-mers have the ability to activate cellular immune responsesin the host [112] For example N-trimethyl chitosan-mono-N-carboxymethyl chitosan (TMCMCC) NPs appeared tobe very promising as an adjuvant and delivery system forantigens Intranasal vaccination with tetanus toxoid loadedTMCMCC NPs (2835 plusmn 25 nm) was shown to induceboth the mucosal and systemic immune response (enhancedantibody response) The enhanced immunoglobulin G (IgG)immune response could be explained by the sustained releaseof the toxoid [113]

Some polymer NPs were reported to activate immunesystem through modulating the activation and capabilityof immune cells such as dendritic cells and T cells [114ndash116] Amphiphilic NPs possessed pathogen-mimicking prop-erties by activating DCs similar to lipopolysaccharide (LPS)thus it has the ability to activate innate immune response[114] Poly(methyl vinyl ether-co-maleic anhydride) NPs(149 plusmn 2 nm) activated DCs through TLR stimulation ininnate immune system [115] As well the sulfonate (245 nm)and phosphonate-functionalized (227 nm) polystyrene NPsinduced the maturation of immature DCs and significantlyenhancedT cells stimulatory capacity indicating a shift toTh1response [116]

329 Other NPs Dendrimers have the ability to stimu-late immune system and can be used as potential candi-dates for vaccines [76] Maltose-functionalized dendrimer-peptide complex is a potential DC-based vaccine candi-date by stimulating DC and activating the immune system[117] Research also showed that Pan-DR-binding epitope-derivatized-dendrimer could reduce the effective dose ofliposomal amphotericin B inmurine cutaneous leishmaniasisand enhance adaptive immunity by activating strong parasitespecific T-cell responses [56]

Protein NPs have shown immunostimulating propertiesin recent studies [118ndash120] Self-assembled protein NPs thatdisplayed epitopes of the repeat sequence in circumsporo-zoite protein of plasmodium falciparum (PfCSP) elicited astrong immune response against PfCSP [119 121] In additionprotein NPs mimic viruses have the ability to facilitate DCsactivation and cross-presentationThese proteinNPs codeliv-ered with peptide epitopes to DCs showed an increased andprolonged CD8+ T cell activation [120]

A lipidNPwas investigated in aDNAvaccine applicationThis NP which decorated with stearyl-conjugated KALAan 120572-helical peptide (sequence WEAKLAKALAKALAK-HLAKALAKALKACEA) showed enhancement of transgeneexpression this enhancement was closely related to immune-activation [122] A cationic solid-lipid NP was used as a vac-cine to deliver a DNA vaccine against visceral leishmaniasisHigh levels of IFN-120574 and low levels of IL-10 production weredetected in BALBc mice after administration of the DNAvaccine delivered by this cationic solid-lipid NP This NPinduced a strongTh1 immune response indicating its poten-tial as therapeutic agent against visceral leishmaniasis [57]Nanolipoprotein conjugated with TLR agonists monophos-phoryl lipid A or CpG oligodeoxynucleotides significantlyenhanced the immunostimulatory profiles compared to theagonists alone Moreover the BALBc mice pretreated withCpGnanolipoprotein coloaded nanoconstructs but not CpGalone survived a lethal influenza challenge [58] Researchalso indicated that intravenous injection of liposome-DNAcomplexes elicited production of IFN-120572 and IFN-120573 in vivowhich suggested that the liposome-DNA complexes caninduce inflammation and cause systemic toxicity [123] Inanother study it was reported that Doxil an PEGylatedliposomal formulation of doxorubicin may cause hyper-sensitivity reactions while the standard doxorubicin didnot indicating that liposomes might be responsible for thishypersensitivity [59] It was speculated that the complementsystem activation by Doxil may play a key role in this effect[59]

4 The Factors Affecting Immunomodulationof NPs

Many factors contribute to immunomodulation of NPs Thenature of NPs such as composition surface chemistry sizeshape and protein-binding ability dominates these interac-tions Besides individual difference and exposure route alsocontribute to immunomodulation of NPs

41 Composition Composition of NPs lays a vital role inthe interactions between NPs and immune system Forexample QDs showed high immunotoxicity [50 51] becausethey release heavy metal ions Some other NPs exhibit lessimmunotoxicity [17 23 39 44 54] immunogenic [15 32]or no effect [45] The different core of NPs gave differentreaction in allergy mass For example CNTs and GNPsshowed adjuvant effect and led to hypersensitivity in theseallergy masses [25 26 36] while fullerene often showedimmunosuppression [14 31]

42 Surface Chemistry For NPs with the same compositionsurface properties may also affect the immune system Engi-neered NPs such as CNTs fullerenes GNPs and silica NPscan be modified with diverse surface chemistry This mayalter their immune response both in vitro and in vivo

Eighty diversely functionalized multiwall nanotube(MWNT) induced different levels of protein bindingcytotoxicity and immune responses (Figure 2) [124] The

modification of MWCNTs significantly alleviated nuclearfactor kappa B (NF-120581B) activation and reduced immuno-toxicity ofMWCNTs in BALBcmice [125] Carboxyfullereneactivated immune system of C57BL6 mice by prolongingthe infiltrating neutrophils to enhance the bactericidalactivity of neutrophils [30] while hydroxylated fullerenesinterferedwith the innate immune system in fatheadminnow[31] MWCNTs-PEG induced less generation of ROS andcytotoxicity in macrophages than MWCNTs-COOH whichwas in correspondence with the lower cellular uptake ofMWCNTs-PEG [126] The monolayer-protected GNPs invivo were studied Simple place-exchange reactions withinthe monolayer by short chain mercaptotetraethylene glycolhave been used The short chain at lower concentrations didnot trigger the immune system to produce anti-PEG antibody[33] However high concentration mixed monolayer coatedNPs initiated an immune response [32] Silica NPs (70 nm)induced strong inflammation by intraperitoneal injectionbut these inflammatory responses could be dramaticallysuppressed by surface modification by carboxyl groups [52]The toxicity of porous silica NPs to immune cells was surfacechemistry and surface charge-dependent Compare tosurface hydrophobicity surface charge had stronger impacton NPsrsquo immunotoxicity in vitro and in vivo Positivelycharged hydrophobic NPs showed more DNA damage thannegatively charged hydrophilic NPs [127]

43 Size Size is another important parameter that deter-mines the interaction with organisms When examinedimmunity is induced by a series of differentially sized (2040 49 67 93 101 and 123 nm) polystyrene nanobeads IFN-120574 induction from CD8+ T cells was limited to 40 and 49 nmbeads while 93ndash123 nmbeads inducedCD4+ T cell activationand increased IL-4 levelThese results showed that the size ofnanobead for vaccination could influence the type 1type 2cytokine balance This would be useful in the developmentof vaccines against common human pathogens [128] 200 nmNPs increased more antigen-specific polyfunctional CD4+ Tcells as compared to 30 nm NPs The immunoactivity of dis-accharides coated GNPs is strongly dependent on size Theyused 2 and 5 nm GNPs coated with disaccharides These NPsactivated the macrophages and induced the proliferation of Tcells and the increase of IL-2 levels The 5 nmNPs performedfar better than 2 nmones (increasedAPC proliferationMHCII expression T cell proliferation and IL-2 expression) [107]Other researches indicated that single instillation (250 375or 500 120583gmouse) of 35 plusmn 14 nm iron oxide NPs inducedhigher levels of inflammation and immunodepression than147plusmn48 nm ones [88] Repeated intratracheal administrationof high dose (4 times 500120583gmouse) and intermediate dose (4 times250 120583gmouse) of the same NPs inhibited the allergic Th2-dominated response induced by OVA The low dose (4 times100 120583gmouse) of 147 plusmn 48 nm iron oxide particles had nosignificant effect but the low dose (4 times 100 120583gmouse) of 35plusmn14 nm particles had an adjuvant effect on theTh2 response toOVA [45] Aggregate size may also affect the immunotoxicityof QDs The toxicity of CdSCdTe QDs was size dependentLarge CdSCdTe QD aggregates (25 nmndash100 nm) reduced

44 Protein Binding When NPs enter the body throughinjection they firstly interact with blood [129] The plasmaprotein binding on the NPs surface such as apolipoprotein Eand transferrinmay contribute to the activationdeactivationof receptor-dependent signaling [130]

The amount and types of proteins adsorbed on the NPsaffect the interactions of cells and NPs and the biologicalresponses [131 132]The composition surface characteristicsand shape of NPs affect the manners that the proteinsbind to them [129 133ndash136] The blood proteins adsorbedonto the NPs include immunoglobulins apolipoproteins andproteins of the complement system among many othersThese proteins may act as signals for immune responses [137138] Furthermore NPs may induce conformational changesin the structure of adsorbed proteins Negatively chargedpoly(acrylic acid-) conjugated GNPs bound with fibrinogenand induced the unfolding of this protein which promotedinteraction with Mac-1 an integrin receptor This activationincreased the NF-120581B signalling pathway and released inflam-matory cytokines [139]

45 Exposure Route Exposure route is another factor affect-ing the immunomodulation ofNPsTheoutcomes of immuneresponse are dependent on entrance of NPs In the lungsDCs pulmonary epithelium and macrophages play animportant role in handling foreign materials In the bloodleukocyte such as neutrophil eosinophil basophil lympho-cyte and monocyte play a vital role Single intratrachealinstillation of 500120583gmouse iron oxide NPs (35 plusmn 14 nmand 147 plusmn 48 nm) induced lung inflammation and decreasedpulmonary immune responses against sheep erythrocytes[88] Pharyngeal aspiration of SWCNTs modified systemicimmunity by modulating DCs function [19] Intravenouslyadministration of iron oxide NPs (587 nm) could sup-press the infiltration and functional activity of Th1 cellsand macrophages [44] Intravenous injection of graphenenanosheets activated a Th2 immune response which con-sisted of neutrophilic influx and a significant increase inIL-5 IL-13 IL-33 in the bronchoalvelar lavage fluid [23]The dosage of administration is also important Intratrachealinjection of iron oxide NPs (35 plusmn 14 nm) inhibited theallergic response in OVA-sensitized mice at a dosage of 4 times250120583gmouse or 4 times 500 120583gmouse but showed adjuvanteffect at a dosage of 4 times 100 120583gmouse [45]

5 The Mechanisms of ImmunomodulationInduced by NPs

NPs interact with both innate and adaptive immune cellsaffect their functions and disturb immune system (Figure 3)

Inflammation is an important response of immune sys-tem which can be induced by NPs evidenced by the pro-duction of cytokines or chemokines Oxidative stress causedby NPs is reported to be the main downstream events ofthe inflammation NPs have large surface areas and strong

oxidative abilities than normal particles [140] Oxidativedamage induced by NPs is an important factor of immuneimbalance [11] Many types of NPs have been shown toproduce ROS in vitro and in vivo and enhance immunefunction or inflammatory response [40 49 53 86 141] Freeradical-induced tissue damage plays an important role ininflammatory diseases [142 143]

The signal pathway to induce ROS and mediate inflam-mation was reported Among them TLR4 signaling pathwaywas documented GO could induce intracellular ROS whichdecreased the viability of macrophages and induced necrosisby a TLR4 signaling pathway (Figure 4) [144] TLR is areceptor of the innate immune system and innate immunitycould be triggered by stimulating TLRs and lead to strongadaptive immunity [115] Activation of the TLR pathwayscould induce chronic inflammation and ROS [145] Resentresearch indicated that quantum dots could activate myeloiddifferentiation primary response gene 88 (MyD88 which isan adapter protein to activate NF-120581B) dependent-TLRs inmcrophages and activated NF-120581B [146]

NF-120581B pathway is another key regulator of immuneresponse [125 147ndash149] As an important regulator of proin-flammatory gene expression synthesis of cytokines suchas IL-1120573 IL-6 IL-8 and TNF-120572 is mediated by NF-120581B

Activation of NF-120581B may induce human inflammatory dis-eases [150 151] It was reported that negatively chargedpoly(acrylic acid-) conjugated GNP activated the NF-120581Bsignalling pathway in THP-1 cells The cells released inflam-matory cytokines including TNF-120572 and IL-8 [139] Andcitrate-stabilized 10 nm GNPs could induce activation of anNF-120581B regulated luciferase reporter in murine B-lymphocytecell line (CH12LX) and altered the cell function [152]

NPs may also disturb the immune balance by inappro-priate maturationactivation of APCs such as DCs [26 153]Intratracheal instillation of 43 nmMIONs the alveolar regionof BALBc mice could generate a significant number ofexosomes These exosomes were quickly eliminated from thealveolar region into systemic circulation and transferred theirsignals to the immune system which resulted in maturationof DCs and activation of splenic T cells and the exosome-induced T-cell activation is more efficient in OVA-sensitizedmice [42 43] Cytotoxicity to immune cells may contribute toimmunosuppression of NPs QDs may decrease the viabilityof hemocytes in Elliption complanata mussels [50] andreduced phagocytosis on bivalves and fish [97]

Recent reports indicated that NPs could modulate thehomeostasis of immune cells including the shift of Th1Th2balance [43 44 89] and monocyte homeostasis [154] Forexample magnetic iron oxide NPs activated the T cellsinduced a Th1 polarization and aggravated inflammation[43]Other studies showed that SWCNTs accentuatedThcellsimmunity includingTh2 (IL-4uarr IL-5uarr and IL-13uarr) andTh17

(IL-17Auarr IL-23uarr) The inappropriate maturationactivationof APCs such as DCs might be responsible for these accen-tuated Th cells immunity [26 153] The normal immunesystem keeps a Th1Th2 balance in order to achieve anappropriate immune response Selectively activating Th1 orTh2 cells results in immune deviation and breaks the balanceof immune system In addition MWCNTs could selectivelydecrease phagocytosis-competent monocytes and promoteadhesion of the phagocytosis-incompetent monocytes inblood flow [154]

6 Conclusion

The immune response of NPs is like a double-edged swordin nanomedicine applications by bringing both benefits andharms We should take advantage of the benefits from theimmunomodulating properties of NPs and on the otherhand avoid the undesirable immune responses in order tominimize the systemic side effects The factors affecting theimmune response are complex including particle compo-sition size surface chemistry plasma protein binding andexposure route Investigation of the relationship betweenproperties of NPs and systemic immune response is crucialfor their application in medicine and other areas Althoughtreatments of acute and long-term immune toxicities havebeen developed current approaches of prediction preven-tion and treatment of nanoimmunomodulation are stilllacking encouraging further in-depth studies

A lipidNPwas investigated in aDNAvaccine applicationThis NP which decorated with stearyl-conjugated KALAan 120572-helical peptide (sequence WEAKLAKALAKALAK-HLAKALAKALKACEA) showed enhancement of transgeneexpression this enhancement was closely related to immune-activation [122] A cationic solid-lipid NP was used as a vac-cine to deliver a DNA vaccine against visceral leishmaniasisHigh levels of IFN-120574 and low levels of IL-10 production weredetected in BALBc mice after administration of the DNAvaccine delivered by this cationic solid-lipid NP This NPinduced a strongTh1 immune response indicating its poten-tial as therapeutic agent against visceral leishmaniasis [57]Nanolipoprotein conjugated with TLR agonists monophos-phoryl lipid A or CpG oligodeoxynucleotides significantlyenhanced the immunostimulatory profiles compared to theagonists alone Moreover the BALBc mice pretreated withCpGnanolipoprotein coloaded nanoconstructs but not CpGalone survived a lethal influenza challenge [58] Researchalso indicated that intravenous injection of liposome-DNAcomplexes elicited production of IFN-120572 and IFN-120573 in vivowhich suggested that the liposome-DNA complexes caninduce inflammation and cause systemic toxicity [123] Inanother study it was reported that Doxil an PEGylatedliposomal formulation of doxorubicin may cause hyper-sensitivity reactions while the standard doxorubicin didnot indicating that liposomes might be responsible for thishypersensitivity [59] It was speculated that the complementsystem activation by Doxil may play a key role in this effect[59]

4 The Factors Affecting Immunomodulationof NPs

Many factors contribute to immunomodulation of NPs Thenature of NPs such as composition surface chemistry sizeshape and protein-binding ability dominates these interac-tions Besides individual difference and exposure route alsocontribute to immunomodulation of NPs

41 Composition Composition of NPs lays a vital role inthe interactions between NPs and immune system Forexample QDs showed high immunotoxicity [50 51] becausethey release heavy metal ions Some other NPs exhibit lessimmunotoxicity [17 23 39 44 54] immunogenic [15 32]or no effect [45] The different core of NPs gave differentreaction in allergy mass For example CNTs and GNPsshowed adjuvant effect and led to hypersensitivity in theseallergy masses [25 26 36] while fullerene often showedimmunosuppression [14 31]

42 Surface Chemistry For NPs with the same compositionsurface properties may also affect the immune system Engi-neered NPs such as CNTs fullerenes GNPs and silica NPscan be modified with diverse surface chemistry This mayalter their immune response both in vitro and in vivo

Eighty diversely functionalized multiwall nanotube(MWNT) induced different levels of protein bindingcytotoxicity and immune responses (Figure 2) [124] The

modification of MWCNTs significantly alleviated nuclearfactor kappa B (NF-120581B) activation and reduced immuno-toxicity ofMWCNTs in BALBcmice [125] Carboxyfullereneactivated immune system of C57BL6 mice by prolongingthe infiltrating neutrophils to enhance the bactericidalactivity of neutrophils [30] while hydroxylated fullerenesinterferedwith the innate immune system in fatheadminnow[31] MWCNTs-PEG induced less generation of ROS andcytotoxicity in macrophages than MWCNTs-COOH whichwas in correspondence with the lower cellular uptake ofMWCNTs-PEG [126] The monolayer-protected GNPs invivo were studied Simple place-exchange reactions withinthe monolayer by short chain mercaptotetraethylene glycolhave been used The short chain at lower concentrations didnot trigger the immune system to produce anti-PEG antibody[33] However high concentration mixed monolayer coatedNPs initiated an immune response [32] Silica NPs (70 nm)induced strong inflammation by intraperitoneal injectionbut these inflammatory responses could be dramaticallysuppressed by surface modification by carboxyl groups [52]The toxicity of porous silica NPs to immune cells was surfacechemistry and surface charge-dependent Compare tosurface hydrophobicity surface charge had stronger impacton NPsrsquo immunotoxicity in vitro and in vivo Positivelycharged hydrophobic NPs showed more DNA damage thannegatively charged hydrophilic NPs [127]

43 Size Size is another important parameter that deter-mines the interaction with organisms When examinedimmunity is induced by a series of differentially sized (2040 49 67 93 101 and 123 nm) polystyrene nanobeads IFN-120574 induction from CD8+ T cells was limited to 40 and 49 nmbeads while 93ndash123 nmbeads inducedCD4+ T cell activationand increased IL-4 levelThese results showed that the size ofnanobead for vaccination could influence the type 1type 2cytokine balance This would be useful in the developmentof vaccines against common human pathogens [128] 200 nmNPs increased more antigen-specific polyfunctional CD4+ Tcells as compared to 30 nm NPs The immunoactivity of dis-accharides coated GNPs is strongly dependent on size Theyused 2 and 5 nm GNPs coated with disaccharides These NPsactivated the macrophages and induced the proliferation of Tcells and the increase of IL-2 levels The 5 nmNPs performedfar better than 2 nmones (increasedAPC proliferationMHCII expression T cell proliferation and IL-2 expression) [107]Other researches indicated that single instillation (250 375or 500 120583gmouse) of 35 plusmn 14 nm iron oxide NPs inducedhigher levels of inflammation and immunodepression than147plusmn48 nm ones [88] Repeated intratracheal administrationof high dose (4 times 500120583gmouse) and intermediate dose (4 times250 120583gmouse) of the same NPs inhibited the allergic Th2-dominated response induced by OVA The low dose (4 times100 120583gmouse) of 147 plusmn 48 nm iron oxide particles had nosignificant effect but the low dose (4 times 100 120583gmouse) of 35plusmn14 nm particles had an adjuvant effect on theTh2 response toOVA [45] Aggregate size may also affect the immunotoxicityof QDs The toxicity of CdSCdTe QDs was size dependentLarge CdSCdTe QD aggregates (25 nmndash100 nm) reduced

44 Protein Binding When NPs enter the body throughinjection they firstly interact with blood [129] The plasmaprotein binding on the NPs surface such as apolipoprotein Eand transferrinmay contribute to the activationdeactivationof receptor-dependent signaling [130]

The amount and types of proteins adsorbed on the NPsaffect the interactions of cells and NPs and the biologicalresponses [131 132]The composition surface characteristicsand shape of NPs affect the manners that the proteinsbind to them [129 133ndash136] The blood proteins adsorbedonto the NPs include immunoglobulins apolipoproteins andproteins of the complement system among many othersThese proteins may act as signals for immune responses [137138] Furthermore NPs may induce conformational changesin the structure of adsorbed proteins Negatively chargedpoly(acrylic acid-) conjugated GNPs bound with fibrinogenand induced the unfolding of this protein which promotedinteraction with Mac-1 an integrin receptor This activationincreased the NF-120581B signalling pathway and released inflam-matory cytokines [139]

45 Exposure Route Exposure route is another factor affect-ing the immunomodulation ofNPsTheoutcomes of immuneresponse are dependent on entrance of NPs In the lungsDCs pulmonary epithelium and macrophages play animportant role in handling foreign materials In the bloodleukocyte such as neutrophil eosinophil basophil lympho-cyte and monocyte play a vital role Single intratrachealinstillation of 500120583gmouse iron oxide NPs (35 plusmn 14 nmand 147 plusmn 48 nm) induced lung inflammation and decreasedpulmonary immune responses against sheep erythrocytes[88] Pharyngeal aspiration of SWCNTs modified systemicimmunity by modulating DCs function [19] Intravenouslyadministration of iron oxide NPs (587 nm) could sup-press the infiltration and functional activity of Th1 cellsand macrophages [44] Intravenous injection of graphenenanosheets activated a Th2 immune response which con-sisted of neutrophilic influx and a significant increase inIL-5 IL-13 IL-33 in the bronchoalvelar lavage fluid [23]The dosage of administration is also important Intratrachealinjection of iron oxide NPs (35 plusmn 14 nm) inhibited theallergic response in OVA-sensitized mice at a dosage of 4 times250120583gmouse or 4 times 500 120583gmouse but showed adjuvanteffect at a dosage of 4 times 100 120583gmouse [45]

5 The Mechanisms of ImmunomodulationInduced by NPs

NPs interact with both innate and adaptive immune cellsaffect their functions and disturb immune system (Figure 3)

Inflammation is an important response of immune sys-tem which can be induced by NPs evidenced by the pro-duction of cytokines or chemokines Oxidative stress causedby NPs is reported to be the main downstream events ofthe inflammation NPs have large surface areas and strong

oxidative abilities than normal particles [140] Oxidativedamage induced by NPs is an important factor of immuneimbalance [11] Many types of NPs have been shown toproduce ROS in vitro and in vivo and enhance immunefunction or inflammatory response [40 49 53 86 141] Freeradical-induced tissue damage plays an important role ininflammatory diseases [142 143]

The signal pathway to induce ROS and mediate inflam-mation was reported Among them TLR4 signaling pathwaywas documented GO could induce intracellular ROS whichdecreased the viability of macrophages and induced necrosisby a TLR4 signaling pathway (Figure 4) [144] TLR is areceptor of the innate immune system and innate immunitycould be triggered by stimulating TLRs and lead to strongadaptive immunity [115] Activation of the TLR pathwayscould induce chronic inflammation and ROS [145] Resentresearch indicated that quantum dots could activate myeloiddifferentiation primary response gene 88 (MyD88 which isan adapter protein to activate NF-120581B) dependent-TLRs inmcrophages and activated NF-120581B [146]

NF-120581B pathway is another key regulator of immuneresponse [125 147ndash149] As an important regulator of proin-flammatory gene expression synthesis of cytokines suchas IL-1120573 IL-6 IL-8 and TNF-120572 is mediated by NF-120581B

Activation of NF-120581B may induce human inflammatory dis-eases [150 151] It was reported that negatively chargedpoly(acrylic acid-) conjugated GNP activated the NF-120581Bsignalling pathway in THP-1 cells The cells released inflam-matory cytokines including TNF-120572 and IL-8 [139] Andcitrate-stabilized 10 nm GNPs could induce activation of anNF-120581B regulated luciferase reporter in murine B-lymphocytecell line (CH12LX) and altered the cell function [152]

NPs may also disturb the immune balance by inappro-priate maturationactivation of APCs such as DCs [26 153]Intratracheal instillation of 43 nmMIONs the alveolar regionof BALBc mice could generate a significant number ofexosomes These exosomes were quickly eliminated from thealveolar region into systemic circulation and transferred theirsignals to the immune system which resulted in maturationof DCs and activation of splenic T cells and the exosome-induced T-cell activation is more efficient in OVA-sensitizedmice [42 43] Cytotoxicity to immune cells may contribute toimmunosuppression of NPs QDs may decrease the viabilityof hemocytes in Elliption complanata mussels [50] andreduced phagocytosis on bivalves and fish [97]

Recent reports indicated that NPs could modulate thehomeostasis of immune cells including the shift of Th1Th2balance [43 44 89] and monocyte homeostasis [154] Forexample magnetic iron oxide NPs activated the T cellsinduced a Th1 polarization and aggravated inflammation[43]Other studies showed that SWCNTs accentuatedThcellsimmunity includingTh2 (IL-4uarr IL-5uarr and IL-13uarr) andTh17

(IL-17Auarr IL-23uarr) The inappropriate maturationactivationof APCs such as DCs might be responsible for these accen-tuated Th cells immunity [26 153] The normal immunesystem keeps a Th1Th2 balance in order to achieve anappropriate immune response Selectively activating Th1 orTh2 cells results in immune deviation and breaks the balanceof immune system In addition MWCNTs could selectivelydecrease phagocytosis-competent monocytes and promoteadhesion of the phagocytosis-incompetent monocytes inblood flow [154]

6 Conclusion

The immune response of NPs is like a double-edged swordin nanomedicine applications by bringing both benefits andharms We should take advantage of the benefits from theimmunomodulating properties of NPs and on the otherhand avoid the undesirable immune responses in order tominimize the systemic side effects The factors affecting theimmune response are complex including particle compo-sition size surface chemistry plasma protein binding andexposure route Investigation of the relationship betweenproperties of NPs and systemic immune response is crucialfor their application in medicine and other areas Althoughtreatments of acute and long-term immune toxicities havebeen developed current approaches of prediction preven-tion and treatment of nanoimmunomodulation are stilllacking encouraging further in-depth studies

44 Protein Binding When NPs enter the body throughinjection they firstly interact with blood [129] The plasmaprotein binding on the NPs surface such as apolipoprotein Eand transferrinmay contribute to the activationdeactivationof receptor-dependent signaling [130]

The amount and types of proteins adsorbed on the NPsaffect the interactions of cells and NPs and the biologicalresponses [131 132]The composition surface characteristicsand shape of NPs affect the manners that the proteinsbind to them [129 133ndash136] The blood proteins adsorbedonto the NPs include immunoglobulins apolipoproteins andproteins of the complement system among many othersThese proteins may act as signals for immune responses [137138] Furthermore NPs may induce conformational changesin the structure of adsorbed proteins Negatively chargedpoly(acrylic acid-) conjugated GNPs bound with fibrinogenand induced the unfolding of this protein which promotedinteraction with Mac-1 an integrin receptor This activationincreased the NF-120581B signalling pathway and released inflam-matory cytokines [139]

45 Exposure Route Exposure route is another factor affect-ing the immunomodulation ofNPsTheoutcomes of immuneresponse are dependent on entrance of NPs In the lungsDCs pulmonary epithelium and macrophages play animportant role in handling foreign materials In the bloodleukocyte such as neutrophil eosinophil basophil lympho-cyte and monocyte play a vital role Single intratrachealinstillation of 500120583gmouse iron oxide NPs (35 plusmn 14 nmand 147 plusmn 48 nm) induced lung inflammation and decreasedpulmonary immune responses against sheep erythrocytes[88] Pharyngeal aspiration of SWCNTs modified systemicimmunity by modulating DCs function [19] Intravenouslyadministration of iron oxide NPs (587 nm) could sup-press the infiltration and functional activity of Th1 cellsand macrophages [44] Intravenous injection of graphenenanosheets activated a Th2 immune response which con-sisted of neutrophilic influx and a significant increase inIL-5 IL-13 IL-33 in the bronchoalvelar lavage fluid [23]The dosage of administration is also important Intratrachealinjection of iron oxide NPs (35 plusmn 14 nm) inhibited theallergic response in OVA-sensitized mice at a dosage of 4 times250120583gmouse or 4 times 500 120583gmouse but showed adjuvanteffect at a dosage of 4 times 100 120583gmouse [45]

5 The Mechanisms of ImmunomodulationInduced by NPs

NPs interact with both innate and adaptive immune cellsaffect their functions and disturb immune system (Figure 3)

Inflammation is an important response of immune sys-tem which can be induced by NPs evidenced by the pro-duction of cytokines or chemokines Oxidative stress causedby NPs is reported to be the main downstream events ofthe inflammation NPs have large surface areas and strong

oxidative abilities than normal particles [140] Oxidativedamage induced by NPs is an important factor of immuneimbalance [11] Many types of NPs have been shown toproduce ROS in vitro and in vivo and enhance immunefunction or inflammatory response [40 49 53 86 141] Freeradical-induced tissue damage plays an important role ininflammatory diseases [142 143]

The signal pathway to induce ROS and mediate inflam-mation was reported Among them TLR4 signaling pathwaywas documented GO could induce intracellular ROS whichdecreased the viability of macrophages and induced necrosisby a TLR4 signaling pathway (Figure 4) [144] TLR is areceptor of the innate immune system and innate immunitycould be triggered by stimulating TLRs and lead to strongadaptive immunity [115] Activation of the TLR pathwayscould induce chronic inflammation and ROS [145] Resentresearch indicated that quantum dots could activate myeloiddifferentiation primary response gene 88 (MyD88 which isan adapter protein to activate NF-120581B) dependent-TLRs inmcrophages and activated NF-120581B [146]

NF-120581B pathway is another key regulator of immuneresponse [125 147ndash149] As an important regulator of proin-flammatory gene expression synthesis of cytokines suchas IL-1120573 IL-6 IL-8 and TNF-120572 is mediated by NF-120581B

Activation of NF-120581B may induce human inflammatory dis-eases [150 151] It was reported that negatively chargedpoly(acrylic acid-) conjugated GNP activated the NF-120581Bsignalling pathway in THP-1 cells The cells released inflam-matory cytokines including TNF-120572 and IL-8 [139] Andcitrate-stabilized 10 nm GNPs could induce activation of anNF-120581B regulated luciferase reporter in murine B-lymphocytecell line (CH12LX) and altered the cell function [152]

NPs may also disturb the immune balance by inappro-priate maturationactivation of APCs such as DCs [26 153]Intratracheal instillation of 43 nmMIONs the alveolar regionof BALBc mice could generate a significant number ofexosomes These exosomes were quickly eliminated from thealveolar region into systemic circulation and transferred theirsignals to the immune system which resulted in maturationof DCs and activation of splenic T cells and the exosome-induced T-cell activation is more efficient in OVA-sensitizedmice [42 43] Cytotoxicity to immune cells may contribute toimmunosuppression of NPs QDs may decrease the viabilityof hemocytes in Elliption complanata mussels [50] andreduced phagocytosis on bivalves and fish [97]

Recent reports indicated that NPs could modulate thehomeostasis of immune cells including the shift of Th1Th2balance [43 44 89] and monocyte homeostasis [154] Forexample magnetic iron oxide NPs activated the T cellsinduced a Th1 polarization and aggravated inflammation[43]Other studies showed that SWCNTs accentuatedThcellsimmunity includingTh2 (IL-4uarr IL-5uarr and IL-13uarr) andTh17

(IL-17Auarr IL-23uarr) The inappropriate maturationactivationof APCs such as DCs might be responsible for these accen-tuated Th cells immunity [26 153] The normal immunesystem keeps a Th1Th2 balance in order to achieve anappropriate immune response Selectively activating Th1 orTh2 cells results in immune deviation and breaks the balanceof immune system In addition MWCNTs could selectivelydecrease phagocytosis-competent monocytes and promoteadhesion of the phagocytosis-incompetent monocytes inblood flow [154]

6 Conclusion

The immune response of NPs is like a double-edged swordin nanomedicine applications by bringing both benefits andharms We should take advantage of the benefits from theimmunomodulating properties of NPs and on the otherhand avoid the undesirable immune responses in order tominimize the systemic side effects The factors affecting theimmune response are complex including particle compo-sition size surface chemistry plasma protein binding andexposure route Investigation of the relationship betweenproperties of NPs and systemic immune response is crucialfor their application in medicine and other areas Althoughtreatments of acute and long-term immune toxicities havebeen developed current approaches of prediction preven-tion and treatment of nanoimmunomodulation are stilllacking encouraging further in-depth studies

44 Protein Binding When NPs enter the body throughinjection they firstly interact with blood [129] The plasmaprotein binding on the NPs surface such as apolipoprotein Eand transferrinmay contribute to the activationdeactivationof receptor-dependent signaling [130]

The amount and types of proteins adsorbed on the NPsaffect the interactions of cells and NPs and the biologicalresponses [131 132]The composition surface characteristicsand shape of NPs affect the manners that the proteinsbind to them [129 133ndash136] The blood proteins adsorbedonto the NPs include immunoglobulins apolipoproteins andproteins of the complement system among many othersThese proteins may act as signals for immune responses [137138] Furthermore NPs may induce conformational changesin the structure of adsorbed proteins Negatively chargedpoly(acrylic acid-) conjugated GNPs bound with fibrinogenand induced the unfolding of this protein which promotedinteraction with Mac-1 an integrin receptor This activationincreased the NF-120581B signalling pathway and released inflam-matory cytokines [139]

45 Exposure Route Exposure route is another factor affect-ing the immunomodulation ofNPsTheoutcomes of immuneresponse are dependent on entrance of NPs In the lungsDCs pulmonary epithelium and macrophages play animportant role in handling foreign materials In the bloodleukocyte such as neutrophil eosinophil basophil lympho-cyte and monocyte play a vital role Single intratrachealinstillation of 500120583gmouse iron oxide NPs (35 plusmn 14 nmand 147 plusmn 48 nm) induced lung inflammation and decreasedpulmonary immune responses against sheep erythrocytes[88] Pharyngeal aspiration of SWCNTs modified systemicimmunity by modulating DCs function [19] Intravenouslyadministration of iron oxide NPs (587 nm) could sup-press the infiltration and functional activity of Th1 cellsand macrophages [44] Intravenous injection of graphenenanosheets activated a Th2 immune response which con-sisted of neutrophilic influx and a significant increase inIL-5 IL-13 IL-33 in the bronchoalvelar lavage fluid [23]The dosage of administration is also important Intratrachealinjection of iron oxide NPs (35 plusmn 14 nm) inhibited theallergic response in OVA-sensitized mice at a dosage of 4 times250120583gmouse or 4 times 500 120583gmouse but showed adjuvanteffect at a dosage of 4 times 100 120583gmouse [45]

5 The Mechanisms of ImmunomodulationInduced by NPs

NPs interact with both innate and adaptive immune cellsaffect their functions and disturb immune system (Figure 3)

Inflammation is an important response of immune sys-tem which can be induced by NPs evidenced by the pro-duction of cytokines or chemokines Oxidative stress causedby NPs is reported to be the main downstream events ofthe inflammation NPs have large surface areas and strong

oxidative abilities than normal particles [140] Oxidativedamage induced by NPs is an important factor of immuneimbalance [11] Many types of NPs have been shown toproduce ROS in vitro and in vivo and enhance immunefunction or inflammatory response [40 49 53 86 141] Freeradical-induced tissue damage plays an important role ininflammatory diseases [142 143]

The signal pathway to induce ROS and mediate inflam-mation was reported Among them TLR4 signaling pathwaywas documented GO could induce intracellular ROS whichdecreased the viability of macrophages and induced necrosisby a TLR4 signaling pathway (Figure 4) [144] TLR is areceptor of the innate immune system and innate immunitycould be triggered by stimulating TLRs and lead to strongadaptive immunity [115] Activation of the TLR pathwayscould induce chronic inflammation and ROS [145] Resentresearch indicated that quantum dots could activate myeloiddifferentiation primary response gene 88 (MyD88 which isan adapter protein to activate NF-120581B) dependent-TLRs inmcrophages and activated NF-120581B [146]

NF-120581B pathway is another key regulator of immuneresponse [125 147ndash149] As an important regulator of proin-flammatory gene expression synthesis of cytokines suchas IL-1120573 IL-6 IL-8 and TNF-120572 is mediated by NF-120581B

Activation of NF-120581B may induce human inflammatory dis-eases [150 151] It was reported that negatively chargedpoly(acrylic acid-) conjugated GNP activated the NF-120581Bsignalling pathway in THP-1 cells The cells released inflam-matory cytokines including TNF-120572 and IL-8 [139] Andcitrate-stabilized 10 nm GNPs could induce activation of anNF-120581B regulated luciferase reporter in murine B-lymphocytecell line (CH12LX) and altered the cell function [152]

NPs may also disturb the immune balance by inappro-priate maturationactivation of APCs such as DCs [26 153]Intratracheal instillation of 43 nmMIONs the alveolar regionof BALBc mice could generate a significant number ofexosomes These exosomes were quickly eliminated from thealveolar region into systemic circulation and transferred theirsignals to the immune system which resulted in maturationof DCs and activation of splenic T cells and the exosome-induced T-cell activation is more efficient in OVA-sensitizedmice [42 43] Cytotoxicity to immune cells may contribute toimmunosuppression of NPs QDs may decrease the viabilityof hemocytes in Elliption complanata mussels [50] andreduced phagocytosis on bivalves and fish [97]

Recent reports indicated that NPs could modulate thehomeostasis of immune cells including the shift of Th1Th2balance [43 44 89] and monocyte homeostasis [154] Forexample magnetic iron oxide NPs activated the T cellsinduced a Th1 polarization and aggravated inflammation[43]Other studies showed that SWCNTs accentuatedThcellsimmunity includingTh2 (IL-4uarr IL-5uarr and IL-13uarr) andTh17

(IL-17Auarr IL-23uarr) The inappropriate maturationactivationof APCs such as DCs might be responsible for these accen-tuated Th cells immunity [26 153] The normal immunesystem keeps a Th1Th2 balance in order to achieve anappropriate immune response Selectively activating Th1 orTh2 cells results in immune deviation and breaks the balanceof immune system In addition MWCNTs could selectivelydecrease phagocytosis-competent monocytes and promoteadhesion of the phagocytosis-incompetent monocytes inblood flow [154]

6 Conclusion

The immune response of NPs is like a double-edged swordin nanomedicine applications by bringing both benefits andharms We should take advantage of the benefits from theimmunomodulating properties of NPs and on the otherhand avoid the undesirable immune responses in order tominimize the systemic side effects The factors affecting theimmune response are complex including particle compo-sition size surface chemistry plasma protein binding andexposure route Investigation of the relationship betweenproperties of NPs and systemic immune response is crucialfor their application in medicine and other areas Althoughtreatments of acute and long-term immune toxicities havebeen developed current approaches of prediction preven-tion and treatment of nanoimmunomodulation are stilllacking encouraging further in-depth studies

Activation of NF-120581B may induce human inflammatory dis-eases [150 151] It was reported that negatively chargedpoly(acrylic acid-) conjugated GNP activated the NF-120581Bsignalling pathway in THP-1 cells The cells released inflam-matory cytokines including TNF-120572 and IL-8 [139] Andcitrate-stabilized 10 nm GNPs could induce activation of anNF-120581B regulated luciferase reporter in murine B-lymphocytecell line (CH12LX) and altered the cell function [152]

NPs may also disturb the immune balance by inappro-priate maturationactivation of APCs such as DCs [26 153]Intratracheal instillation of 43 nmMIONs the alveolar regionof BALBc mice could generate a significant number ofexosomes These exosomes were quickly eliminated from thealveolar region into systemic circulation and transferred theirsignals to the immune system which resulted in maturationof DCs and activation of splenic T cells and the exosome-induced T-cell activation is more efficient in OVA-sensitizedmice [42 43] Cytotoxicity to immune cells may contribute toimmunosuppression of NPs QDs may decrease the viabilityof hemocytes in Elliption complanata mussels [50] andreduced phagocytosis on bivalves and fish [97]

Recent reports indicated that NPs could modulate thehomeostasis of immune cells including the shift of Th1Th2balance [43 44 89] and monocyte homeostasis [154] Forexample magnetic iron oxide NPs activated the T cellsinduced a Th1 polarization and aggravated inflammation[43]Other studies showed that SWCNTs accentuatedThcellsimmunity includingTh2 (IL-4uarr IL-5uarr and IL-13uarr) andTh17

(IL-17Auarr IL-23uarr) The inappropriate maturationactivationof APCs such as DCs might be responsible for these accen-tuated Th cells immunity [26 153] The normal immunesystem keeps a Th1Th2 balance in order to achieve anappropriate immune response Selectively activating Th1 orTh2 cells results in immune deviation and breaks the balanceof immune system In addition MWCNTs could selectivelydecrease phagocytosis-competent monocytes and promoteadhesion of the phagocytosis-incompetent monocytes inblood flow [154]

6 Conclusion

The immune response of NPs is like a double-edged swordin nanomedicine applications by bringing both benefits andharms We should take advantage of the benefits from theimmunomodulating properties of NPs and on the otherhand avoid the undesirable immune responses in order tominimize the systemic side effects The factors affecting theimmune response are complex including particle compo-sition size surface chemistry plasma protein binding andexposure route Investigation of the relationship betweenproperties of NPs and systemic immune response is crucialfor their application in medicine and other areas Althoughtreatments of acute and long-term immune toxicities havebeen developed current approaches of prediction preven-tion and treatment of nanoimmunomodulation are stilllacking encouraging further in-depth studies
