严重急性呼吸综合征冠状病毒2(SARS-CoV-2)是COVID-19(2019冠状病毒病)大流行的原因,是一种正链RNA(+RNA)病毒。与其他+RNA病毒一样,SARS-CoV-2依赖宿主细胞代谢机制生存和复制,重塑细胞膜以产生病毒复制位点。病毒RNA双膜囊泡(DMVs)是+RNA病毒复制的显著特征,在SARS-CoV-2感染的细胞中大量存在。它们的产生涉及宿主脂质代谢的重新布线,包括脂质生物合成途径。病毒也可以从宿主细胞器重定向脂质;在膜接触位点的脂质交换,其中相邻细胞器的膜是紧密并置的,已经涉及几种+RNA病毒的复制。在这里,我们审查目前的理解DMV的生物成因。重点开发的接触网站机械+RNA病毒产生复制细胞器,我们讨论的证据表明,类似的机制支持SARS-CoV-2复制,保护其RNA从宿主细胞免疫反应。
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the cause of the COVID-19 (coronavirus disease 2019) pandemic, is a positive strand RNA (+RNA) virus. Like other +RNA viruses, SARS-CoV-2 is dependent on host cell metabolic machinery to survive and replicate, remodeling cellular membranes to generate sites of viral replication. Viral RNA-containing double-membrane vesicles (DMVs) are a striking feature of +RNA viral replication and are abundant in SARS-CoV-2–infected cells. Their generation involves rewiring of host lipid metabolism, including lipid biosynthetic pathways. Viruses can also redirect lipids from host cell organelles; lipid exchange at membrane contact sites, where the membranes of adjacent organelles are in close apposition, has been implicated in the replication of several +RNA viruses. Here we review current understanding of DMV biogenesis. With a focus on the exploitation of contact site machinery by +RNA viruses to generate replication organelles, we discuss evidence that similar mechanisms support SARS-CoV-2 replication, protecting its RNA from the host cell immune response.
