CELL:我国研究人员从患者中鉴定出抗SARS-CoV-2的潜在中和抗体 

2020-05-18 MedSci原创 MedSci原创

在此,我国研究人员报导,通过对60例康复期患者的抗原富集B细胞进行高通量单细胞RNA和VDJ测序,其快速鉴定出了SARS-CoV-2中和抗体。

今年COVID-19的全球大流行急需治疗和预防干预措施。

在此,我国研究人员报导,通过对60例康复期患者的抗原富集B细胞进行高通量单细胞RNA和VDJ测序,其快速鉴定出了SARS-CoV-2中和抗体。从8,558个抗原结合的IgG1+克隆型中,鉴定出14种强效中和抗体,其中最强效的BD-368-2对假性SARS-CoV-2和真性SARS-CoV-2的IC50分别为1.2 ng/mL和15 ng/mL。

BD-368-2对SARS-CoV-2感染的hACE2-转基因小鼠也表现出较强的治疗和预防作用。

此外,通过对中和抗体与尖晶体三聚体复合物的3.8Å Cryo-EM结构的研究发现,该抗体的表位与ACE2结合位点重叠。

此外,研究人员还证明了SARS-CoV-2中和抗体可以根据其预测的CDR3H结构与SARS-CoV中和抗体的相似性直接选择。

总的来说,该研究证明了通过高通量单细胞B细胞测序可以有效地发现人类中和抗体,以应对大流行性传染病。
