Abstract

The increased affinity of memory antibody responses is due largely to the generation and selection of memory B cells that accumulate somatic mutations after initial antigenic stimulation. Further affinity maturation and mutation also accompany subsequent immunizations. Previous studies have suggested that, like primary antibody-forming cell (AFC) clones, secondary AFC do not accumulate further mutations and, therefore, the origins of progressive affinity maturation remain controversial. Here, we report the generation of somatically mutated memory B cell clones in vitro. Our findings confirm the existence of a naive B cell subset whose progeny, rather than generating AFC, somatically mutate and respond to subsequent antigenic stimulation. Interestingly, upon stimulation, a subset of memory B cells also generates antigen-responsive cells that accumulate further somatic mutations.
