宿主细胞受体在确定病毒嗜性和致病性中起关键作用。然而,除了ACE 2之外,对SARS-CoV-2宿主受体知之甚少。此外,ACE 2单独不能解释SARS-CoV-2的多器官嗜性,也不能解释SARS-CoV-2和SARS-CoV之间的临床差异,这表明其他受体的参与。在这里,我们进行了基因组受体分析,以筛选5054人膜蛋白单独与SARS-CoV-2衣壳刺突(S)蛋白的相互作用。包括ACE 2、ASGR 1和KREMEN 1在内的12种蛋白质被鉴定出具有不同的S结合亲和力和模式。ASGR 1或KREMEN 1在体内外均足以使SARS-CoV-2进入,但对SARS-CoV的进入则无影响。SARS-CoV-2利用不同的ACE 2/ASGR 1/KREMEN 1(ASK)受体组合进入不同的细胞类型,并且在细胞和组织水平上,ASK的共同表达与病毒易感性的相关性明显强于任何单个受体。与单个抗体相比,ASK相关中和抗体的混合物提供了对人肺类器官中SARS-CoV-2感染的最实质性阻断。我们的研究揭示了SARS-CoV-2的相互作用宿主受体组,并将ASGR 1和KREMEN 1确定为在ACE 2非依赖性病毒进入中发挥重要作用的替代功能受体,为深入了解SARS-CoV-2的嗜性和发病机制以及进一步研究COVID-19提供了社区资源和潜在的治疗策略。
Host cellular receptors play key roles in the determination of virus tropism and pathogenesis. However, little is known about SARS-CoV-2 host receptors with the exception of ACE2. Furthermore, ACE2 alone cannot explain the multi-organ tropism of SARS-CoV-2 nor the clinical differences between SARS-CoV-2 and SARS-CoV, suggesting the involvement of other receptor(s). Here, we performed genomic receptor profiling to screen 5054 human membrane proteins individually for interaction with the SARS-CoV-2 capsid spike (S) protein. Twelve proteins, including ACE2, ASGR1, and KREMEN1, were identified with diverse S-binding affinities and patterns. ASGR1 or KREMEN1 is sufficient for the entry of SARS-CoV-2 but not SARS-CoV in vitro and in vivo. SARS-CoV-2 utilizes distinct ACE2/ASGR1/KREMEN1 (ASK) receptor combinations to enter different cell types, and the expression of ASK together displays a markedly stronger correlation with virus susceptibility than that of any individual receptor at both the cell and tissue levels. The cocktail of ASK-related neutralizing antibodies provides the most substantial blockage of SARS-CoV-2 infection in human lung organoids when compared to individual antibodies. Our study revealed an interacting host receptome of SARS-CoV-2, and identified ASGR1 and KREMEN1 as alternative functional receptors that play essential roles in ACE2-independent virus entry, providing insight into SARS-CoV-2 tropism and pathogenesis, as well as a community resource and potential therapeutic strategies for further COVID-19 investigations.
