固有抗病毒免疫是指直接限制病毒复制和组装的先天免疫形式,从而使细胞对特定类别或物种的病毒不允许。固有免疫是由限制性因子赋予的,这些限制性因子在很大程度上预先存在于某些细胞类型中,尽管这些因子可以通过病毒感染进一步诱导。内在病毒限制因子识别特定的病毒成分,但与通过诱导干扰素和其他抗病毒分子间接抑制病毒感染的其他模式识别受体不同,内在抗病毒因子立即直接阻断病毒复制。本文综述了限制人类免疫缺陷病毒(HIV)和流感病毒感染的内在抗病毒因子的作用。
Intrinsic antiviral immunity refers to a form of innate immunity that directly restricts viral replication and assembly, thereby rendering a cell non-permissive to a specific class or species of viruses. Intrinsic immunity is conferred by restriction factors that are largely preexisting in certain cell types, although these factors can be further induced by virus infection. Intrinsic viral restriction factors recognize specific viral components, but unlike other pattern recognition receptors that inhibit viral infection indirectly by inducing interferons and other antiviral molecules, intrinsic antiviral factors block viral replication immediately and directly. This review focuses on recent advances in understanding the roles of intrinsic antiviral factors that restrict infection by human immunodeficiency virus (HIV) and influenza virus.
