感染脊椎动物宿主的病毒必须克服干扰素(IFN)介导的抗病毒反应才能复制并传播到新的宿主。IFN反应的复杂调控允许病毒在多个水平上拮抗IFN。然而,似乎没有一种策略是万能的,病毒已经采取了多种手段来抑制这种宿主防御。这篇综述并没有详尽地涵盖病毒干扰素拮抗剂的所有机制。相反,它研究了病毒用来破坏IFN反应的十种最常见的策略,并举例说明了最近10年发表在《细胞宿主与微生物》杂志上的出版物。诱导和逃避IFN的病毒-宿主相互作用是一个丰富的研究领域,因为大量的宿主和病毒产物调节这种反应,导致宿主和病原体之间复杂的舞蹈,以实现病毒复制、宿主疾病和生存之间的最佳平衡。病毒是一种可怕的病原体,它利用被感染的细胞机制,同时解除宿主的抗病毒防御。García-Sastre回顾了病毒对抗抗病毒干扰素反应的最常见机制,说明了感知病毒感染和调节抗病毒先天免疫反应的途径的复杂性。
Viruses infecting vertebrate hosts must overcome the interferon (IFN)-mediated antiviral response to replicate and propagate to new hosts. The complex regulation of the IFN response allows viruses to antagonize IFN at multiple levels. However, no single strategy appears to be the golden ticket, and viruses have adopted multiple means to dampen this host defense. This Review does not exhaustively cover all mechanisms of viral IFN antagonism. Rather it examines the ten most common strategies that viruses use to subvert the IFN response with examples from publications appearing in the last 10 years of Cell Host & Microbe. The virus-host interactions involved in induction and evasion of IFN represent a fertile area of research due to the significant large number of host and viral products that regulate this response, resulting in an intricate dance between hosts and their pathogens to achieve an optimal balance between virus replication, host disease, and survival. Viruses are formidable pathogens that take advantage of the infected cell machinery while disarming the antiviral host defenses. García-Sastre reviews the most common mechanisms used by viruses to antagonize the antiviral interferon response, illustrating the complexity of pathways that sense viral infection and regulate antiviral innate immune responses.
