Old dog with new tricks: SARS-CoV-2 variant–specific B cells complement imprinted memory

Q: What does this research mean for the field?

Both memory and de novo antibody clones are capable of neutralizing SARS-CoV-2 variants, but they possess distinct origins and target different viral epitopes. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

Key Points

To determine how preexisting memory B cells and newly generated antibody clones neutralize emerging SARS-CoV-2 variants.
Evaluated the clonal origin, antigenic targets, and neutralization capacity of memory-derived and de novo antibody lineages against SARS-CoV-2 variants.
Both recalled memory B cells and newly recruited de novo antibody clones neutralize SARS-CoV-2 variants.
Memory and de novo antibody clones originate from distinct B-cell lineages and bind to different antigenic targets across variants.
