严重急性呼吸综合征冠状病毒 2 (SARS-CoV-2) 是 2019 年冠状病毒病 (COVID-19) 的病原体,它利用宿主细胞血管紧张素转换酶 2 (ACE2) 进入细胞。 ACE2 的遗传分析发现了不同人群特有的几种单核苷酸多态性 (SNP)。分子动力学模拟表明,其中一些 SNP 可能影响 SARS-CoV-2 和 ACE2 之间的相互作用,从而为 SARS-CoV-2 感染性和严重程度观察到的区域差异提供部分解释。然而,人群特异性 ACE2 SNP 在 SARS-CoV-2 感染性中的重要性尚不清楚,因为尚未进行体外验证研究。在这里,我们分析了特定人群中发现的八个 SNP 对受体结合和体外细胞进入的影响。除了导致无义突变降低 ACE2 表达的 SNP 外,所选的 SNP 均未显着改变 ACE2 与 SARS-CoV-2 刺突蛋白 (SARS-2-S) 之间的相互作用,该蛋白负责受体识别和细胞进入,或 SARS-2-S 介导的病毒细胞进入效率。我们的研究结果表明,ACE2 多态性对 SARS-CoV-2 依赖 ACE2 的细胞进入细胞的影响有限,并强调了未来研究其他宿主基因的人群特异性 SNP 参与 SARS-CoV-2 感染易感性的重要性。
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of coronavirus disease 2019 (COVID-19), employs host-cell angiotensin-converting enzyme 2 (ACE2) for cell entry. Genetic analyses of ACE2 have identified several single-nucleotide polymorphisms (SNPs) specific to different human populations. Molecular dynamics simulations have indicated that several of these SNPs could affect interactions between SARS-CoV-2 and ACE2, thereby providing a partial explanation for the regional differences observed in SARS-CoV-2 infectivity and severity. However, the significance of population-specific ACE2 SNPs in SARS-CoV-2 infectivity is unknown, as no in vitro validation studies have been performed. Here, we analyzed the impact of eight SNPs found in specific populations on receptor binding and cell entry in vitro. Except for a SNP causing a nonsense mutation that reduced ACE2 expression, none of the selected SNPs markedly altered the interaction between ACE2 and the SARS-CoV-2 spike protein (SARS-2-S), which is responsible for receptor recognition and cell entry, or the efficiency of viral cell entry mediated by SARS-2-S. Our findings indicate that ACE2 polymorphisms have limited impact on the ACE2-dependent cell entry of SARS-CoV-2 and underscore the importance of future studies on the involvement of population-specific SNPs of other host genes in susceptibility toward SARS-CoV-2 infection.
