质膜中富含胆固醇的脂筏微域被认为在包膜病毒生命周期中发挥着重要作用。然而,胆固醇在呼吸道RNA病毒的组装、感染性和稳定性中的功能作用尚不完全清楚。我们之前报道过,胆固醇降低剂消耗细胞胆固醇,通过抑制病毒组装来减少人类副流感病毒 1 型 (hPIV1) 颗粒的产生。在这项研究中,我们分析了胆固醇对甲型流感病毒(IAV)和呼吸道合胞病毒(RSV)产生的作用。与 hPIV1 不同,用这些药物处理人呼吸道细胞并不会减少病毒颗粒的产生。然而,释放的病毒体密度不太均匀且不稳定。在释放的病毒粒子中添加外源胆固醇可以恢复病毒的稳定性和感染性。总的来说,这些数据表明胆固醇在维持 IAV 和 RSV 膜结构中发挥着关键作用,这对于维持病毒稳定性和感染性至关重要。
Cholesterol-rich lipid raft microdomains in the plasma membrane are considered to play a major role in the enveloped virus lifecycle. However, the functional role of cholesterol in assembly, infectivity and stability of respiratory RNA viruses is not fully understood. We previously reported that depletion of cellular cholesterol by cholesterol-reducing agents decreased production of human parainfluenza virus type 1 (hPIV1) particles by inhibiting virus assembly. In this study, we analyzed the role of cholesterol on influenza A virus (IAV) and respiratory syncytial virus (RSV) production. Unlike hPIV1, treatment of human airway cells with the agents did not decrease virus particle production. However, the released virions were less homogeneous in density and unstable. Addition of exogenous cholesterol to the released virions restored virus stability and infectivity. Collectively, these data indicate a critical role of cholesterol in maintaining IAV and RSV membrane structure that is essential for sustaining viral stability and infectivity.
