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.

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. Sixteen healthy 30-day-old weaned DPL pigs were selected from the Jiaxiang Dapulian farm, Jining City, China, and 15 healthy 30-day-old weaned DLY pigs were obtained from a commercial farm with high standards of animal health. These pigs were free from PRRSV, porcine circovirus type 2 (PCV2), pseudorabies virus (PRV), and classical swine fever virus (CSFV) as determined by ELISA tests for serum antibodies; the absence of PRRSV was also confirmed by real-time quantitative reverse transcription PCR (qRT-PCR). Pigs were randomly assigned into two groups and reared in separate places: the PRRSV-infected group consisted of 11 DPL and 10 DLY pigs, and the control group consisted of five DPL and five DLY pigs. Infections in the pigs proceeded via inoculation with 2 ml of a viral suspension of PRRSV (at a tissue culture infectious dose of 105) by dripping the solution into the nasal cavity of each pig. The control group was treated with an identical volume of PBS by the same method. Rectal temperatures and clinical examinations on the pigs were recorded daily during the experiment. Anticoagulant-treated blood and untreated blood samples were collected separately at 0, 7, 14, and 21 days post-infection (dpi) from the infected and control groups for assaying CD4+, CD8+, cytokine (interleukin (IL) 1 beta (IL-1β), IL-2, IL-10, interferon (IFN)-gamma (IFN-γ), tumor necrosis factor-alpha (TNF-α), and immunoglobulin G (IgG) protein levels. Lung samples for microarray analysis and real-time qRT-PCR analysis were collected from six infected DLY and DPL pigs (three pigs for each breed) immediately post-slaughter at 28 dpi. Total RNA was isolated from lung tissue samples and purified using an RNeasy Mini kit according to the manufacturer’s protocol. RNA was prepared using the GeneChip (AFF-900623) one cycle target for the labeling and control reagents, and the labeled RNA was hybridized in an Affymetrix Hybridization Oven 640 for sequencing.

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 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 .

Project description:One of the largest impediments for commercial swine production is the presence of Porcine Reproductive and Respiratory Syndrome virus (PRRSV), a devastating RNA viral infection that is responsible for over $1 billion in loss in the U.S. annually. The challenge with combating PRRSV is a combination of the effect of an extraordinary rate of mutation, the ability to infect macrophages, and subversion of host immune response through a series of actions leading to both immunomodulation and immune evasion. Currently there are a handful of commercial vaccines on the market that have been shown to be effective against homologous infections, but struggle against heterologous or mixed strain infections. However, vaccination is the current best strategy for combating PRRSV, making research into new vaccine technology key. To address these issues with PRRSV and host antiviral functions a novel modified-live vaccine (MLV) able to stimulate known anti-viral interferons was created and examined for its ability to potentiate effective immunity and better protection. Here, we examine gene expression in the liver of pigs vaccinated with our novel vaccine, given the liver’s large role in anti-viral responses and vaccine metabolism. Our study indicated that pigs administered the novel vaccine experience homeostatic gene expression consistent with less inflammation and T-cell depletion risk than pigs administered the commercial vaccine.
