病毒凋亡模拟,定义为暴露于病原体表面的磷脂酰丝氨酸,正在成为包膜病毒促进感染的共同主题。在这篇进展文章中,阿马拉和美世讨论了病毒如何获得磷脂酰丝氨酸,以及这种模仿如何促进细胞进入和逃避免疫反应。本文的在线版本(doi:10.1038/nrmicro 3469)包含补充材料,可供授权用户使用。作为机会致病菌,病毒已经进化出许多巧妙的策略来操纵宿主细胞进行感染性进入和复制。病毒凋亡模拟,定义为暴露的磷脂酰丝氨酸-细胞凋亡的标志物-在病原体表面上,正在成为一个共同的主题所使用的包膜病毒,以促进感染。集中在四个最好的描述的例子(牛痘病毒,登革热病毒,埃博拉病毒和假型慢病毒),我们总结了我们目前的理解,细胞凋亡模拟作为一种机制,病毒进入,结合和免疫逃避。我们还描述了最近的例子,无包膜病毒,使用这种模仿策略,并讨论未来的方向,以及如何病毒凋亡模仿可以有针对性的治疗。本文的在线版本(doi:10.1038/nrmicro 3469)包含补充材料,可供授权用户使用。
Viral apoptotic mimicry, defined by the exposure of phosphatidylserine on the pathogen surface, is emerging as a common theme used by enveloped viruses to promote infection. In this Progress article, Amara and Mercer discuss how viruses acquire phosphatidylserine and how this mimicry might facilitate cell entry and evasion of the immune response. The online version of this article (doi:10.1038/nrmicro3469) contains supplementary material, which is available to authorized users. As opportunistic pathogens, viruses have evolved many elegant strategies to manipulate host cells for infectious entry and replication. Viral apoptotic mimicry, defined by the exposure of phosphatidylserine — a marker for apoptosis — on the pathogen surface, is emerging as a common theme used by enveloped viruses to promote infection. Focusing on the four best described examples (vaccinia virus, dengue virus, Ebola virus and pseudotyped lentivirus), we summarize our current understanding of apoptotic mimicry as a mechanism for virus entry, binding and immune evasion. We also describe recent examples of non-enveloped viruses that use this mimicry strategy, and discuss future directions and how viral apoptotic mimicry could be targeted therapeutically.
