严重急性呼吸综合征冠状病毒2(SARS-CoV-2)多种变种的出现突显了可能的动物到人(人畜共患病)和人到动物(人畜共患病)传播的重要性,以及在动物物种中的潜在传播。无论是在体外还是在体内,已经证实了一系列动物物种对SARS-CoV-2的敏感性。然而,SARS-CoV-2如此广泛的宿主谱的分子基础仍然难以捉摸。在这里,我们从结构和遗传学上分析了SARS-CoV-2的Spike蛋白与其受体血管紧张素转换酶2(ACE2)之间的相互作用,特别是对SARS-CoV-2的受体结合域(RBDS)的相互作用,以确定SARS-CoV-2宿主谱的结构基础。我们在现有基于动物感染的模型的背景下描述我们的发现,以提供关于动物中可能的病毒持久性及其对未来根除新冠肺炎的影响的基础。
The emergence of multiple variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) highlights the importance of possible animal-to-human (zoonotic) and human-to-animal (zooanthroponotic) transmission and potential spread within animal species. A range of animal species have been verified for SARS-CoV-2 susceptibility, either in vitro or in vivo. However, the molecular bases of such a broad host spectrum for the SARS-CoV-2 remains elusive. Here, we structurally and genetically analysed the interaction between the spike protein, with a particular focus on receptor binding domains (RBDs), of SARS-CoV-2 and its receptor angiotensin-converting enzyme 2 (ACE2) for all conceivably susceptible groups of animals to gauge the structural bases of the SARS-CoV-2 host spectrum. We describe our findings in the context of existing animal infection-based models to provide a foundation on the possible virus persistence in animals and their implications in the future eradication of COVID-19.
