B cells generate plasma cells (PCs) and memory B cells (MBCs) to combat recurrent pathogens. B cell receptor (BCR) affinity dictates fate decisions in response to model antigens, but the factors regulating B cell fate during infection remain unknown. Here, we used respiratory and gastrointestinal infection models to study B cell selection across barrier tissues in mice. Memory selection was governed by tissue-specific cues: Selection in the lung was skewed toward MBCs, whereas the gut favored PC entry, even in response to the same pathogen. Divergence was linked to differential BCR isotype usage across barrier tissues rather than differential affinity maturation. In the gut, the commensal-induced TGF-β-rich milieu promoted class-switching to IgA, which skewed selection toward PCs, a process that was counteracted by the IgA cytosolic tail domain. Thus, mucosal B cell selection integrates tissue-specific cues by relying on BCR isotype usage, with implications for nasal and oral vaccine development.
