Utilizing mRNA display, we identify a set of antibodies against SARS-CoV-2 spike (S) proteins and characterize the structures of nAbs that recognize epitopes in the S1 subunit of the S glycoprotein. These structural studies reveal distinct binding modes for several antibodies, including the targeting of rare cryptic epitopes in the receptor-binding domain (RBD) of S that interact with angiotensin-converting enzyme 2 (ACE2) to initiate infection, as well as the S1 subdomain 1. Further, we engineer a potent ACE2-blocking nAb to sustain binding to S RBD with the E484K and L452R substitutions found in multiple SARS-CoV-2 variants. We demonstrate that mRNA display is an approach for the rapid identification of nAbs that can be used in combination to combat emerging SARS-CoV-2 variants. #1: ジャーナル: bioRxiv / 年: 2021 タイトル: Rapid Identification of Neutralizing Antibodies against SARS-CoV-2 Variants by mRNA Display. 著者: Shiho Tanaka / C Anders Olson / Christopher O Barnes / Wendy Higashide / Marcos Gonzalez / Justin Taft / Ashley Richardson / Marta Martin-Fernandez / Dusan Bogunovic / Priyanthi N P ...著者: Shiho Tanaka / C Anders Olson / Christopher O Barnes / Wendy Higashide / Marcos Gonzalez / Justin Taft / Ashley Richardson / Marta Martin-Fernandez / Dusan Bogunovic / Priyanthi N P Gnanapragasam / Pamela J Bjorkman / Patricia Spilman / Kayvan Niazi / Shahrooz Rabizadeh / Patrick Soon-Shiong 要旨: The increasing prevalence of SARS-CoV-2 variants with the ability to escape existing humoral protection conferred by previous infection and/or immunization necessitates the discovery of broadly- ...The increasing prevalence of SARS-CoV-2 variants with the ability to escape existing humoral protection conferred by previous infection and/or immunization necessitates the discovery of broadly-reactive neutralizing antibodies (nAbs).
