Protective immunity requires a diverse, polyclonal B cell repertoire. We demonstrate that affinity maturation of the humoral response to a hapten is impaired when pre-existing clonally restricted cells recognizing the hapten are dominant in the B cell repertoire. B1- 8i+/− mice, which feature a high frequency of B cells with nitrophenyl (NP) binding specificity, respond to NP-haptenated proteins with the production of NP-specific antibodies, but affinity maturation is impaired due to insufficient generation of high affinity antibody producing cells. We manipulated the frequency of NP-specific B cells by adoptive transfer of B1-8 B cells into naïve, wild-type recipients. Remarkably, when 104 B1-8 B cells were transferred, these cells supported efficient affinity maturation and plasma cell differentiation. In contrast, when 106 B1-8 cells were transferred, affinity maturation did not occur. These data indicate that restricting the frequency of clonally related B cells is required to support affinity maturation.
