Upon infection with Bluetongue virus (BTV), an arthropod-borne virus, type I interferon (IFN-I) is produced in vivo and in vitro. IFN-I is essential for the establishment of an antiviral cellular response, and most if not all viruses have elaborated strategies to counteract its action. In this study, we assessed the ability of BTV to interfere with IFN-I synthesis and identified the nonstructural viral protein NS3 as an antagonist of the IFN-I system.
在感染蓝舌病病毒(BTV)这种虫媒病毒后,I 型干扰素(IFN-I)会在体内和体外被产生。IFN-I 对于建立抗病毒的细胞反应至关重要,而且如果不是所有病毒,那么大部分病毒都已经进化出了对抗 IFN-I 作用的策略。在这项研究中,我们评估了 BTV 干扰 IFN-I 合成的能力,并确定非结构病毒蛋白 NS3 是 IFN-I 系统的拮抗剂。
