About OMICS Group OMICS Group is an amalgamation of Open Access publications and

worldwide international science conferences and events. Established in the year 2007 with the sole aim of making the information on Sciences and technology ‘Open Access’, OMICS Group publishes 500 online open access scholarly journals in all aspects of Science, Engineering, Management and Technology journals. OMICS Group has been instrumental in taking the knowledge on Science & technology to the doorsteps of ordinary men and women. Research Scholars, Students, Libraries, Educational Institutions, Research centers and the industry are main stakeholders that benefitted greatly from this knowledge dissemination. OMICS Group also organizes 500 International conferences annually across the globe, where knowledge transfer takes place through debates, round table discussions, poster presentations, workshops, symposia and exhibitions.

Deviation of activation statuses

Routes for preventing

Summary

1. Porcine monocytic cells at different activation statuses, interact differentially with PRRSV

2. Key genes in the pathways such as lipid metabolism, epigenetics and interferon signaling are revealed among significant DEGs.

3. Signature genes revealed in PRRSV—infected macrophages at each activation status infer the mechanism of PRRSV-cell interaction.

4. Understanding and modulating cell activation status of monocytic innate immune cells provides a framework for optimizing antiviral immunity

Objective and Approach

Aims:

1. Develop rat obesity model integratively induced by a high-fat diet and Had-36 infection

2. Validate obesity phenotypes including body weight, fat index, plasma leptin level, and

parameters associated with gut/adipose inflammation

3. Extract ileal RNA from LF lean, Had-36+LF, HF and Had-36+HF obese groups

4. Perform transcriptomic analyses using 8-wk ileal and hypothalamus samples

5. Analyze gene ontology and pathway integration, and determine obesity-linked innate

immune genes

Tissue samples taken

at 8, 15, 30 wks

blood samples taken weekly

HF + Had-36 infected group compared with control group

All 30, including 10 disease/immunity related (highlighted), pathways show little direct relation with lipid metabolic pathways but are highly relevant to intracellular and inter-organism communication (p<0.05)

1. Infection of Had-36 synergizes with the induction of obesity by high-fat diet in rats; however, Had-36 infection has little effect in obesity induction in rats fed the control diet.

2. Either high-fat diet or Had-36 infection increases gut permeability and inflammation but has no synergistic effect (actually having antagonistic effect)

3. At 8-wk post treatment, rat ileal transcriptome shows significant down-regulation of multiple families of immune and metabolic genes in the HF and HF+Had-36 groups, as well as reprograming of circadian rhythm pathway.

Hypothesis: Viral infection and high-fat diet can induce obesity independently, and in particular may contribute to prevalence of obesity synergistically.

Results and Discussion

Either high-fat diet or Had-36 infection increases gut permeability but has no synergistic effect (actually having antagonistic effect) . Thus, the development of obesity is associated but may not proportionally correlated with an increase in gut permeability.
