Authors: Jianhui Nie / Jingshu Xie / Shuo Liu / Jiajing Wu / Chuan Liu / Jianhui Li / Yacui Liu / Meiyu Wang / Huizhen Zhao / Yabo Zhang / Jiawei Yao / Lei Chen / Yuelei Shen / Yi Yang / Hong-Wei ...Authors: Jianhui Nie / Jingshu Xie / Shuo Liu / Jiajing Wu / Chuan Liu / Jianhui Li / Yacui Liu / Meiyu Wang / Huizhen Zhao / Yabo Zhang / Jiawei Yao / Lei Chen / Yuelei Shen / Yi Yang / Hong-Wei Wang / Youchun Wang / Weijin Huang / ![]() Abstract: Coronavirus disease 2019 (COVID-19), a pandemic disease caused by the newly emerging severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has caused more than 3.8 million deaths to date. ...Coronavirus disease 2019 (COVID-19), a pandemic disease caused by the newly emerging severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has caused more than 3.8 million deaths to date. Neutralizing antibodies are effective therapeutic measures. However, many naturally occurring mutations at the receptor-binding domain (RBD) have emerged, and some of them can evade existing neutralizing antibodies. Here, we utilized RenMab, a novel mouse carrying the entire human antibody variable region, for neutralizing antibody discovery. We obtained several potent RBD-blocking antibodies and categorized them into four distinct groups by epitope mapping. We determined the involved residues of the epitope of three representative antibodies by cryo-electron microscopy (Cryo-EM) studies. Moreover, we performed neutralizing experiments with 50 variant strains with single or combined mutations and found that the mixing of three epitope-distinct antibodies almost eliminated the mutant escape. Our study provides a sound basis for the rational design of fully human antibody cocktails against SARS-CoV-2 and pre-emergent coronaviral threats.  | ||||||
