汉坦病毒可在欧亚大陆引起肾综合征出血热(HFRS),在美洲引起汉坦病毒肺综合征(HPS),死亡率高且机制不明。先天免疫是宿主连接后天免疫以抵抗病毒感染的第一道防线。然而,汉坦病毒在分子和细胞方面进化出了各种策略来逃避宿主的天然免疫监视。干扰素-I (IFN-I) 信号通路是宿主防御的中心环节,可诱导各种抗病毒蛋白来控制感染。本文总结了汉坦病毒的IFN信号通路逃避机制以及调节性细胞死亡和细胞应激等细胞过程的分子机制。此外,汉坦病毒还可以通过细胞机制逃避免疫监视,例如上调免疫检查点分子干扰病毒感染。了解汉坦病毒的抗病毒免疫逃避机制将加深我们对其发病机制的认识,有助于我们开发出更有效的方法来控制和消除汉坦病毒。
Hantavirus can cause hemorrhagic fever with renal syndrome (HFRS) in Eurasia and hantavirus pulmonary syndrome (HPS) in America, with high mortality and unknown mechanisms. Innate immunity is the host’s first-line defense to bridge the acquired immunity against viral infections. However, hantavirus has evolved various strategies in both molecular and cellular aspects to evade the host’s natural immune surveillance. The Interferon-I (IFN-I) signaling pathway, a central link of host defense, induces various antiviral proteins to control the infection. This paper summarizes the molecular mechanisms of hantavirus evasion mechanisms of the IFN signaling pathway and cellular processes such as regulated cell death and cell stress. Besides, hantavirus could also evade immune surveillance evasion through cellular mechanisms, such as upregulating immune checkpoint molecules interfering with viral infections. Understanding hantavirus’s antiviral immune evasion mechanisms will deepen our understanding of its pathogenesis and help us develop more effective methods to control and eliminate hantavirus.
