IFN诱导多种抗病毒效应物。每种病毒都有独特但部分重叠的抗病毒“ISG谱”。干扰素效应物作用于病毒生命周期的多个阶段。IFN信号通路是高度自我强化的。病毒可能劫持干扰素效应物来促进复制。许多病毒触发I型干扰素(IFN)系统,导致数百种干扰素刺激基因(isg)的转录。这些isg的产物发挥了许多抗病毒效应功能,其中许多尚未得到充分描述。最近的努力旨在确定哪些isg是抗病毒的,并进一步确定其作用机制。干扰素效应物在其抑制活性的大小和显示组合抗病毒特性方面变化很大。总的来说,isg可以针对病毒生命周期中的几乎任何步骤。一些最有效的抗病毒效应物通过进一步诱导IFN或isg来增强系统。其他基因增强或促进病毒复制,这表明一些病毒可能已经进化到利用干扰素效应物来获得生存优势。
► IFN induces a diverse range of antiviral effectors. ► Each virus has a unique, but partially overlapping, antiviral ‘ISG profile’. ► IFN effectors target multiple stages in the virus life cycle. ► The IFN signaling pathway is highly self-reinforcing. ► Viruses may hijack IFN effectors to promote replication. Many viruses trigger the type I interferon (IFN) system, leading to the transcription of hundreds of interferon-stimulated genes (ISGs). The products of these ISGs exert numerous antiviral effector functions, many of which are still not fully described. Recent efforts have been aimed at identifying which ISGs are antiviral and further characterizing their mechanisms of action. IFN effectors vary widely in their magnitude of inhibitory activity and display combinatorial antiviral properties. Collectively, ISGs can target almost any step in a virus life cycle. Some of the most potent antiviral effectors reinforce the system by further inducing IFN or ISGs. Other genes enhance or facilitate viral replication, suggesting that some viruses may have evolved to co-opt IFN effectors for a survival advantage.
