Elisabetta Cameroni et al.: Broadly neutralizing antibodies overcome SARS-CoV-2 Omicron antigenic shift, in: Nature 602 (February 2022), pp. 664–670, online in: https://doi.org/10.1038/s41586-021-04386-2. Abstract The recently emerged SARS-CoV-2 Omicron variant encodes 37 amino acid substitutions in the spike protein, 15 of which are in the receptor-binding domain (RBD), thereby raising concerns about the effectiveness of available vaccines and antibody-based therapeutics. In this study, the authors show that the Omicron RBD binds to human ACE2 with enhanced affinity, relative to the Wuhan-Hu-1 RBD, and binds to mouse ACE2. Marked reductions in neutralizing activity were observed against Omicron compared to the ancestral pseudovirus […]
