Abstract

SummaryHow infection by a viral variant showing antigenic drift impacts a preformed mature human memory B cell (MBC) repertoire remains an open question. Here, we studied the MBC response up to 6 months after Omicron BA.1 breakthrough infection in individuals previously vaccinated with three doses of mRNA vaccine. Longitudinal analysis, using single-cell multi-omics and functional analysis of monoclonal antibodies from RBD-specific MBCs, revealed that a BA.1 breakthrough infection mostly recruited pre-existing cross-reactive MBCs with limitedde novoresponse against BA.1-restricted epitopes. Reorganization of clonal hierarchy and new rounds of germinal center reaction, however, combined to maintain diversity and induce progressive maturation of the MBC repertoire against common Hu-1 and BA.1, but not BA.5-restricted, SARS-CoV-2 Spike RBD epitopes. Such remodeling was further associated with marked improvement in overall neutralizing breadth and potency. These findings have fundamental implications for the design of future vaccination booster strategies.

Abstract

The oxidation activity of the mammalian ten-eleven translocation dioxygenase (TET) on 5-methylcytosine (5mC) of DNA is usually monitored by analytical methods such as dot blotting and liquid chromatography-mass spectrometry (LC-MS). Herein, we describe a high throughput capillary gel electrophoresis assay for monitoring the in vitro oxidation of 5mC by TET. The method is rapid and quantitative, and can serve as a powerful tool in mechanistic studies of TET.
