Abstract

SARS-CoV-2 rapidly accumulated mutations in its immunodominant receptor-binding domain (RBD), rendering all clinically authorized monoclonal antibodies (mAbs) ineffective. Liu et al. unveil potent human mAbs that neutralize all tested SARS-CoV-2 variants by locking the Spike protein RBD in a downward conformation, thus inhibiting receptor engagement.

Keywords: Omicron; SARS-CoV-2; broadly neutralizing antibody; cryo-EM; monoclonal antibodies.
