چکیده

Porcine reproductive and respiratory syndrome (PRRS) caused by the PRRS virus (PRRSV) is an important swine disease worldwide. PRRSV has a limited tropism for certain cells, which may at least in part be attributed to the expression of the necessary cellular molecules serving as the virus receptors or factors on host cells for virus binding or entry. However, these molecules conferring PRRSV infection have not been fully characterized. Here we show the identification of non-muscle myosin heavy chain 9 (MYH9) as an essential factor for PRRSV infection using the anti-idiotypic antibody specific to the PRRSV glycoprotein GP5. MYH9 physically interacts with the PRRSV GP5 protein via its C-terminal domain and confers susceptibility of cells to PRRSV infection. These findings indicate that MYH9 is an essential factor for PRRSV infection and provide new insights into PRRSV-host interactions and viral entry, potentially facilitating development of control strategies for this important swine disease.

MicroRNA let-7f-5p Inhibits Porcine Reproductive and Respiratory Syndrome Virus by Targeting MYH9

Porcine reproductive and respiratory syndrome virus (PRRSV) is one of the most important viral pathogens in the swine industry. Current antiviral strategies do not effectively prevent and control PRRSV. Recent reports show that microRNAs (miRNAs) play vital roles in viral infections by post transcriptionally regulating the expression of viral or host genes. Our previous research showed that non...

A retrospective study of risk factors for porcine reproductive and respiratory syndrome virus infection and clinical disease in swine herds in Illinois during the early years of the pandemic

Results: Larger herd size was associated with an increased risk, and isolation of purchased gilts with a decreased risk, of both PRRS virus infection and clinical PRRS. Purchase of semen for AI was associated with an increased risk of PRRS virus infection. Implications: Swine producers should certify that purchased semen is free of PRRS virus, gilts should be isolated prior to introduction to t...

Evaluation of an industry-based sanitation protocol for full-size transport vehicles contaminated with porcine reproductive and respiratory syndrome virus

Objective: To test a protocol for sanitation of full-size commercial transport vehicles contaminated with porcine reproductive and respiratory syndrome virus (PRRSV), utilizing conditions found on commercial swine production units. Conditions included use of cold water for washing (21 ̊C), application of a commercial disinfectant via a low-pressure foamer, and rapid completion of ≤ 2 hours.

Porcine reproductive and respiratory syndrome virus nonstructural protein 1beta modulates host innate immune response by antagonizing IRF3 activation.

Porcine reproductive and respiratory syndrome virus (PRRSV) infection of swine leads to a serious disease characterized by a delayed and defective adaptive immune response. It is hypothesized that a suboptimal innate immune response is responsible for the disease pathogenesis. In the study presented here we tested this hypothesis and identified several nonstructural proteins (NSPs) with innate ...

Induction of type I interferons by a novel porcine reproductive and respiratory syndrome virus isolate.

Porcine reproductive and respiratory syndrome virus (PRRSV) is known to interfere with the signaling of type I interferons (IFNs). Here we found PRRSV A2MC2 induced type I IFNs in cultured cells. A2MC2 replication in MARC-145 cells resulted in the synthesis of IFN-α2 protein, transcript elevation of the IFN-stimulated genes ISG15 and ISG56, and the proteins of the signal transducer and activato...
