Project description:Porcine reproductive and respiratory disease (PRRS) is the most important disease in swine industry worldwide. However, strategies such as vaccination and good biosecurity are not consistently successful to eliminate PRRSV. Though some interesting pathways have been tentatively examined recently, host molecular pathways utilized by PRRSV and the protective immune responses in resistant to PRRSV are largely unknown. In order to answer these questions, we herein characterize changes in global gene expressions in multiple tissues [tonsil, tracheobronchial lymph nodes (TBLN), Cranial lung (CR Lung), and distal lung (D Lung)] in response to PRRSV of high and low virulence. Both vaccinated and unvaccinated pigs are used for this study. Based on Ingenuity Pathway Analysis (IPA), molecule bases of some “black boxes” underlying immune responses are further identified. Our results indicate that cross talks among these pathways and immune balances/competition between host and virus are always happened during the pathogenesis of PRRS. connected loop design was used to accommodate samples from 4 treatment groups.

Project description:Porcine reproductive and respiratory syndrome caused by porcine reproductive and respiratory syndrome virus (PRRSV) is an infectious disease characterized by severe reproductive deficiency in pregnant sows, respiratory symptoms in piglets, and high mortality. In this study, we employed Affymetrix microarray chip technology to compare the gene expression profiles of lung tissue samples from Dapulian (DPL) pigs (a Chinese indigenous pig breed) and Duroc×Landrace×Yorkshire (DLY) pigs after infection with PRRSV. During infection with PRRSV, the DLY pigs exhibited the range of clinical features that typify the disease, while the DPL pigs exhibited only mild signs of the disease. The percentage of CD8+ T cells in the DPL pigs was significantly higher than that in the DLY pigs at 21 days post-infection (dpi) (p< 0.05). Interleukin (IL) 1 beta (IL-1β) and IL-2 levels showed significant differences between the DPL and DLY pigs at 0 and 7 dpi (p< 0.01). For IL-10, the DLY pigs had significantly higher values than the DPL pigs at 0 and 7 dpi (p< 0.01). Significant differences were apparent between the DPL and DLY pigs in terms of their tumor necrosis factor-alpha (TNF-α) and interferon (IFN)-gamma (IFN-γ) levels at 0 and 7 dpi (p< 0.01). Microarray data revealed 16 differentially expressed genes in the lung tissue samples from the DLY and DPL pigs (q≤5%), of which LOC100516029 and LOC100523005 were up-regulated in the PRRSV-infected DPL pigs, while the other 14 genes were down-regulated in the PRRSV-infected DPL pigs compared with the PRRSV-infected DLY pigs. The expression levels of 10 of the 16 genes, namely CCDC84, C6ORF52, THYMOSIN, PRVE, HSPCB, CYP2J2, AMPD3, TOR1AIP2, PTGES3, and ACOX3, were validated by real-time quantitative RT-PCR. This study provides a platform for further investigation of the molecular mechanisms underlying the differential immune responses to PRRSV infection in different breeds or lines of pig. We investigated the response of lung tissues from Dapulian (DPL) pigs (a Chinese indigenous pig breed) and Duroc×Landrace×Yorkshire (DLY) pigs infected with porcine reproductive and respiratory syndrome virus (strain JXA1) by using the Affymetrix Porcine Genome Array.

Project description:Porcine reproductive and respiratory disease (PRRS) is the most important disease in swine industry worldwide. However, strategies such as vaccination and good biosecurity are not consistently successful to eliminate PRRSV. Although some gene expression pathways have been explored recently, host molecular pathways blocked by PRRSV and the protective immune response expressed in pigs resistant to PRRSV are largely unknown. In order to answer these questions, we herein characterize changes in blood gene expression in pigs responding differentially to infection with a well characterized type 2 (North American) PRRSV isolate. Samples are those collected through the PRRS Host Genetics Consortium (PHGC). Samples were those from Tempus tube collected blood of PHGC pigs selected from four response groups according to their serum viral load (0-21 days post infection) and weight gain (0-42 dpi) and characterized as low vs. high viral load and low vs high weight gain . block reference design was used to accommodate samples from 4 treatment groups.

Project description:The aim of this study was to acquire a better understanding of porcine reproductive and respiratory syndrome (PRRS) disease through a deeper knowledge of gene expression changes that occur in pulmonary lymph nodes by comparing PRRS virus (PRRSV), porcine circovirus type 2 (PCV-2), and swine influenza virus (IAV-S) infections. The PRRSV, IAV-S and PCV-2 viral infections followed a clinical course in these domestic pigs typical of experimental infection of young pigs with these viruses. PRRSV isolate SDSU-73 was pathogenic in this study inducing fever, anorexia, listlessness, and dyspnea.

Project description:Porcine reproductive and respiratory syndrome virus (PRRSV) is a causative agent of an important infectious disease causing serious economic losses to swine industry called PRRS (porcine reproductive and respiratory syndrome). The clinical signs of this syndrome indcude respiratory disorders, abortions and variable mortality in piglets. To compare the virulence of highly diverse East European strains belonging to subtype 2 (Russian strain ILI and Belarusian strain BOR) and Danish strain from classical subtype 1 (DAN) the experimental study enrolling infection of piglets was performed. Gene expression profiles of peripheral blood mononuclear cells (PBMC) of piglets infected with three PRRSV strains vs control piglets were analysed by microarray analysis to gain insight into transcriptome changes after PRRSV infection.

Project description:Porcine reproductive and respiratory syndrome (PRRS) is a highly contagious disease caused by porcine reproductive and respiratory syndrome virus (PRRSV). It clinically manifests as fever, bleeding, and respiratory symptoms in pigs of different age groups, as well as reproductive disorders, causing huge economic losses to the global swine industry. RNA interference (RNAi), a highly conserved mechanism mediating post-transcriptional gene silencing, exerts antiviral effects by cleaving viral double-stranded RNA to generate virus-derived siRNA (vsiRNA). VsiRNA-mediated antiviral immunity is widespread in plants and invertebrates, while in mammals, studies have focused on reducing PRRSV viral load in pigs via siRNA delivery. Therefore, PRRSV strains (LY and LY-R) were primarily selected as virus models to infect PAM and Marc-145 cells, respectively. Then, miRNA and vsiRNA analysis were performed and bioinformatics analysis revealed multiple differentially expressed miRNAs following PRRSV infection. Further enrichment analysis indicated that these miRNAs were mainly enriched in metabolic, endocytic, and phosphorylation signaling pathways. Additionally, in Marc-145 cells infected with PRRSV-LY, high abundance of vsiRNA was detected within the PRRSV-N genome. The N-vsiRNA was inserted into vector psilencer4.1. to construct a PS-N plasmid, which is capable of exerting anti-PRRSV (LY, LY-R, and NADC30-like) activity in Marc-145 cells. Finally, the PS-N plasmid was formulated with PLGA-PEI to prepare a nanoparticle mixture, which was delivered to pigs via intramuscular injection to alleviate tissue damage caused by PRRSV-LY infection to a certain extent. In summary, the porcine RNAi system and vsiRNA generated via viral cleavage play a critical role in inhibiting virus replication. This further demonstrates the feasibility of vsiRNA-based antiviral strategies and offers a reference for the prevention and control of various RNA viruses.
