More in detail, a GOF-related phenomenon leading to increased SARS-CoV-2 virulence and/or transmissibility—as clearly exemplified by the “delta” and the “omicron” as well as by other “variants of concern”—would not necessarily imply that viral genetic manipulations made in the laboratory are its exclusive drivers, provided that GOF may also occur as a consequence of a natural selection process. In order to gain a better understanding of SARS-CoV-2 GOF and GOF-associated phenomena, an in-depth knowledge of the complex viral-host interaction dynamics is absolutely needed, while also paying special attention to the human-animal-viral ecological interfaces within an “ad hoc” multidisciplinary, “holistic”, scientific evidence-based and “One Health”-based approach.展开更多
甲型流感病毒(Influenza A virus,IAV)给动物和人类健康带来了极大的威胁。IAV感染会引起宿主细胞一系列免疫反应的激活,这一过程由病毒刺激诱导,宿主因子调控完成。由于宿主因子众多,因此会以不同机制影响流感病毒的感染、复制和致病...甲型流感病毒(Influenza A virus,IAV)给动物和人类健康带来了极大的威胁。IAV感染会引起宿主细胞一系列免疫反应的激活,这一过程由病毒刺激诱导,宿主因子调控完成。由于宿主因子众多,因此会以不同机制影响流感病毒的感染、复制和致病。文章总结了能够调控IAV感染及复制的典型酶类蛋白、宿主调节蛋白和干扰素刺激因子,并归纳了其作用机制,为更好地理解宿主因子抗IAV机制及抗病毒药物靶点的筛选提供一定的理论依据。展开更多
