共循环呼吸道病毒之间的相互作用因其对 17 种病毒传播和临床结果的影响而得到认可。然而,这些病毒-病毒 18 相互作用在细胞水平上的后果尚不清楚。我们用甲型 19 型流感病毒 (IAV) 和呼吸道合胞病毒 (RSV) 共同感染人类肺细胞。超分辨率显微镜将 20 与活细胞成像和扫描电子显微镜相结合,识别出细胞外和 21 膜相关丝状结构,可能由 IAV 和 22 RSV 病毒体的元素组成。冷冻电子断层扫描证实存在嵌合病毒颗粒23,其表现出两种亲本病毒的糖蛋白和核糖核蛋白。功能测定 24 揭示嵌合颗粒促进 IAV 感染缺乏 IAV 受体的细胞,25 证明向性扩大。我们的观察定义了一种以前未知的相互作用 26 ,它可能会影响病毒的发病机制,并对感染 27 生物学产生深远的影响。 28
Interactions between co-circulating respiratory viruses are recognized for their impact on 17 viral transmission and clinical outcomes. However, the consequences of these virus-virus 18 interactions at the cellular level are unclear. We coinfected human lung cells with influenza A 19 virus (IAV) and respiratory syncytial virus (RSV). Super-resolution microscopy combined 20 with live-cell imaging and scanning electron microscopy identified extracellular and 21 membrane-associated filamentous structures, likely composed of elements of both IAV and 22 RSV virions. Cryo-electron tomography confirmed the presence of chimeric virus particles 23 exhibiting glycoproteins and ribonucleoproteins of both parental viruses. Functional assays 24 revealed chimeric particles facilitate IAV infection in cells depleted of IAV receptors, 25 demonstrating expanded tropism. Our observations define a previously unknown interaction 26 that is likely to affect virus pathogenesis and have profound implications for infection 27 biology. 28
