甲型流感病毒核糖核蛋白(vRNP)复合物包含8种基因组负义RNA,每种RNA与病毒核蛋白的多个拷贝和三聚体病毒聚合酶复合物结合。流感病毒的生命周期以vRNP为中心,而vRNP又依赖于宿主细胞过程来执行成功完成病毒生命周期所必需的功能。在这里,我们回顾了我们目前的知识vRNP贩运宿主细胞和这些复合物的功能,在病毒的生命周期的背景下,强调结构如何有助于功能和关键的相互作用与宿主细胞的途径,以及仍然存在的信息差距。更好地了解vRNP如何使用宿主细胞途径对于确定病毒致病性,宿主适应性机制以及最终抗病毒干预的新靶点至关重要。
Influenza A viral ribonucleoprotein (vRNP) complexes comprise the eight genomic negative-sense RNAs, each bound to multiple copies of viral nucleoprotein and a trimeric viral polymerase complex. The influenza virus life cycle centres on the vRNPs, which in turn, rely on host cellular processes to perform functions necessary for the successful completion of the virus life cycle. Here, we review our current knowledge about vRNP trafficking within host cells and the function of these complexes in the context of the virus life cycle, highlighting how structure contributes to function and the critical interactions with host cell pathways, as well as the information gaps that remain. An improved understanding of how vRNPs use host cell pathways is essential to identify mechanisms of virus pathogenicity, host adaptation, and ultimately, new targets for antiviral intervention.
