摘要: Recently, a novel type I interferon alphaomega (IFN-alpha omega), also known as IFN-mu, was identified. However, the biological activity of IFN-alpha omega remain poorly understood. In this study, the porcine IFN-alpha omega (PoIFN-alpha omega) was expressed, purified, and its antiviral activities assessed by its ability to inhibit the cytopathic effect caused by FMDV on IBRS-2 cells. In addition, q-PCR was used to evaluate the expression of IFN-stimulated genes induced by PoIFN-alpha omega. It was found that PoIFN-alpha omega exerted effective antiviral activity against FMDV pre- and post-infection. Additionally, PoIFN-alpha omega induced the transcription of IFN-stimulated genes, including Mx1, ISG15, OAS1, and PKR genes. Our study reported a new indication of PoIFN-alpha omega as an effective anti-FMDV agent for the first time.
