After viral infection, host cells respond by mounting an anti-viral stress response in order to create a hostile atmosphere for viral replication, leading to the shut-off of mRNA translation (protein synthesis) and the assembly of RNA granules. Two of these RNA granules have been well characterized in yeast and mammalian cells, stress granules (SGs), which are translationally silent sites of RNA triage and processing bodies (PBs), which are involved in mRNA degradation. This review discusses the role of these RNA granules in the evasion of anti-viral stress responses through virus-induced remodeling of cellular ribonucleoproteins (RNPs).
病毒感染后，宿主细胞通过启动抗病毒应激反应做出响应，以营造不利于病毒复制的环境，导致mRNA翻译（蛋白质合成）停止和RNA颗粒的组装。其中两种RNA颗粒在酵母和哺乳动物细胞中已得到充分表征，即应激颗粒（SGs），它是RNA分类的翻译沉默位点，以及加工小体（PBs），它参与mRNA降解。本文综述了这些RNA颗粒在病毒诱导的细胞核糖核蛋白（RNP）重塑以逃避抗病毒应激反应中的作用。
