Project description:Porcine reproductive and respiratory syndrome (PRRS), caused by PRRS virus (PRRSV), is the most economically important disease in pig populations. Lung damage is one major pathological condition following PRRSV infection, often leading to animal death. In vivo, PRRSV productive infection occurs predominately in alveolar macrophages of the lung. Here, transcriptome profiling of pulmonary alveolar macrophages (PAMs) from Tongcheng piglets pre- and post- infection of highly pathogenic PRRSV has been performed using porcine Affymetrix GeneChip.

Project description:Porcine reproductive and respiratory syndrome (PRRS) is an economically important disease with a significant impact on the pig industry. It is caused by PRRS virus (PRRSV), which predominantly infects and replicates in porcine pulmonary alveolar macrophages (PAMs), providing a useful in vitro model for understanding the host immune response to PRRSV infection. We pretreated PAMs with porcine IFN-α to induce an antiviral state within the cells and subsequently infected them with highly pathogenic (HP)-PRRSV. Changes in global gene expression in IFN-α-pretreated PAMs in response to HP-PRRSV infection were determined by RNA-sequence analysis. A total of 346 differentially expressed genes (DEGs) were transcriptionally upregulated by porcine IFN-α. Among these up-regulated DEGs, 93 showed significantly attenuated expression levels in response to HP-PRRSV infection. These attenuated DEGs were remarkably enriched in immune-response-related terms, such as 'RIG-Ilike receptor signaling pathway', 'Response to virus', and 'Response to stimulus'. Notably, expression levels of 93.8% (15/16) of antiviral genes (such as PKR, OAS1, IFIT1(ISG56) and ISG15), and genes encoding retinoic-acid-inducible gene-I protein (LOC100737466(DDX58), a cytoplasmic viral RNA sensor), interferon regulatory factor 7 (IRF7, a key transcriptional regulator of type I IFN-dependent immune response), signal transducer and activator of transcription 1 (LOC100738308(STAT1), a transcription factor for IFN-stimulated genes), and tumor necrosis factor-related apoptosis-inducing ligand (TNFSF10, a cytokine initiating proapoptotic signaling cascades) were significantly attenuated by HP-PRRSV infection. These results suggest that HP-PRRSV can counteract the type I IFN-induced antiviral state by interfering with the expression of genes involved in the host-defense response.

Project description:Porcine reproductive and respiratory syndrome (PRRS), caused by PRRS virus (PRRSV), is the most economically important disease in pig populations. Lung damage is one major pathological condition following PRRSV infection, often leading to animal death. In vivo, PRRSV productive infection occurs predominately in alveolar macrophages of the lung. Here, transcriptome profiling of pulmonary alveolar macrophages (PAMs) from Tongcheng piglets pre- and post- infection of highly pathogenic PRRSV has been performed using porcine Affymetrix GeneChip. All animal procedures were performed according to protocols approved by the Biological Studies Animal Care and Use Committee of Hubei Province, China. Piglets used in this study were free from PRRSV, pseudorabies virus (PRV) and porcine circovirus type 2 (PCV2) determined by ELISA test for serum antibodies. Twelve of 5-week-old boars were obtained from three litters (four piglets per litter), and raised in pathogen-free facilities. In order to perform a paired experiment, every four full-sib individuals were divided equally into two groups: one infected group and one control group with 6 piglets in each group. The infected groups were challenged with PRRSV-Wuh2 (3 ml/15 kg, 10-5 TCID50/ml) by intramuscular inoculation. Slaughters were carried out at 0 days post-infection (dpi) for uninfected (control) groups, and at 5 or 7 dpi for infected groups. The PAMs for microarray analysis were collected by bronchoalveolar lavage from three uninfected pigs and three infected pigs at 5 dpi. Total of 6 microarrays have been hybridized in this experiment.

Project description:Porcine reproductive and respiratory syndrome (PRRS) has been one of the most economically important diseases affecting swine industry worldwide and causes great economic losses each year. PRRS virus (PRRSV) replicates mainly in porcine alveolar macrophages (PAMs) and dendritic cells (DCs) and develops persistent infections, antibody-dependent enhancement (ADE), interstitial pneumonia and immunosuppression. But the molecular mechanisms of PRRSV infection still are poorly understood. Here we reported on the first genome-wide host transcriptional responses to normal PRRSV (N-PRRSV) infection using Solexa/Illumina’s digital gene expression (DGE) system, a tag-based high-throughput transcriptome sequencing method, and analyzed systematically the relationship between pulmonary gene expression profiles after N-PRRSV infection and infection pathology. Our results indicated that N-PRRSV appeared to utilize multiple strategies for its long surviral in infected pigs, including subverting host innate immune response, hijacking host lipid metabolism, inducing an anti-apoptotic and anti-inflammatory state as well as developing ADE. Virus-induced pro-inflammatory cytokines, chemokines, adhesion molecules and inflammatory enzymes production and inflammatory cells, antibodies, complement activation were likely to result in the development of inflammatory responses during N-PRRSV infection processing. N-PRRSV-induced immunosuppression might be mediated by apoptosis of infected cells, which caused depletion of immune cells and induced an anti-inflammatory cytokine response in which they were unable to eradicate the primary infection or developed secondary infection. Our systems analysis will benefit for better understanding the molecular pathogenesis of N-PRRSV infection, developing novel antiviral therapies and identifying genetic components for swine resistance/susceptibility to PRRS.

Project description:Porcine reproductive and respiratory syndrome (PRRS), which caused by the porcine reproductive and respiratory syndrome virus (PRRSV), is a serious viral disease affecting global swine industry. At present, PRRSV vaccines fail to prevent this disease. Consequently, new antiviral strategies to compensate for the inefficacy of available vaccines are urgently required. Lysine acetylation is an important post-translational modification (PTM) regulating an array of pathological and physiological conditions. In this study, we profiled the global acetylome using acetylation specific antibody based enrichment and Tandem mass tag (TMT) label LC-MS in PRRSV-infected pulmonary alveolar macrophages (PAMs). As a result, 3731 lysine acetylation sites on 1421 cellular proteins were identified and quantified 6 hours post infection (hpi). Bioinformatics analysis of the differentially acetylated proteins revealed their involvement in various biological processes, including the host immune response and energy metabolism.

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: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 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.
