与其他免疫应答相比,由RNAi途径指导的抗病毒防御采用不同的特异性和效应器机制。抗病毒RNA干扰的特异性是通过Dicer内切酶从病毒衍生的双链RNA加工的siRNA来编程的。含有Argonaute的RNA诱导沉默复合物负载病毒siRNA作为效应物介导RNAi特异性清除病毒。最近的研究提供了证据,病毒衍生的siRNA的生产和抗病毒功能的未分化和分化的哺乳动物细胞感染的一系列RNA病毒时,同源病毒编码的抑制RNA干扰(VSR)是无功能的。在这篇综述中,我们讨论了功能,机制和进化起源的验证哺乳动物VSRs和细胞培养法,他们的鉴定。
The antiviral defense directed by the RNAi pathway employs distinct specificity and effector mechanisms compared with other immune responses. The specificity of antiviral RNAi is programmed by siRNAs processed from virus-derived double-stranded RNA by Dicer endonuclease. Argonaute-containing RNA-induced silencing complex loaded with the viral siRNAs acts as the effector to mediate specific virus clearance by RNAi. Recent studies have provided evidence for the production and antiviral function of virus-derived siRNAs in both undifferentiated and differentiated mammalian cells infected with a range of RNA viruses when the cognate virus-encoded suppressor of RNAi (VSR) is rendered nonfunctional. In this review, we discuss the function, mechanism, and evolutionary origin of the validated mammalian VSRs and cell culture assays for their identification.
