The focus is on understanding how these genetic alterations affect somatic hypermutation and antibody dynamics in B cells. The goal is to determine which groups of mutant mice (G1, G2, G3, G6) show significant differences in antibody titers compared to wild-type mice, indicating the influence of their respective mutations on the immune response."}
