黄病毒科(Flaviviridae)包括黄病毒属(Flavivirus)、瘟病毒属(Pestivirus)、Pegivirus属和肝炎病毒属(Hepacivirus)四个属,它们的基因组结构相似,但瘟病毒属(Pestivirus)和黄病毒属(Flavivirus)的基因组分别编码分泌糖蛋白Erns和NS1。Erns在病毒颗粒的形成和进入细胞中起重要作用,而NS1参与病毒复制复合物和病毒颗粒的形成。相反,已知载脂蛋白参与丙型肝炎病毒(HCV)感染性颗粒的形成,各种分泌性糖蛋白在HCV颗粒形成中发挥类似作用,表明分泌性糖蛋白在感染性颗粒形成中的功能没有强特异性。此外,最近的研究表明,宿主来源的载脂蛋白和病毒来源的Ernsand NS1在HCV和瘟病毒的感染性颗粒形成中发挥着相当的作用。本文综述了分泌糖蛋白在黄病毒科病毒颗粒形成中的作用。
The family Flaviviridae comprises four genera, namely,Flavivirus, Pestivirus, Pegivirus,andHepacivirus.These viruses have similar genome structures, but the genomes ofPestivirusandFlavivirusencode the secretory glycoproteins Ernsand NS1, respectively. Ernsplays an important role in virus particle formation and cell entry, whereas NS1 participates in the formation of replication complexes and virus particles. Conversely, apolipoproteins are known to participate in the formation of infectious particles of hepatitis C virus (HCV) and various secretory glycoproteins play a similar role in HCV particles formation, suggesting that there is no strong specificity for the function of secretory glycoproteins in infectious‐particle formation. In addition, recent studies have shown that host‐derived apolipoproteins and virus‐derived Ernsand NS1 play comparable roles in infectious‐particle formation of both HCV and pestiviruses. In this review, we summarize the roles of secretory glycoproteins in the formation of Flaviviridae virus particles.
