Phenotypic outcomes of B cells in response to BAFF/BAFFR-mediated NF-κB2 activation. Activation of non-canonical NF-κB signaling in response to BAFF contributes to key events throughout the lifespan of a B cell. These include facilitating the survival of immature (Imm) B cells in the periphery and activating transcriptional programs which allow them to mature into follicular and marginal zone (MZ) B cells; contributing to some T-independent immune response; extending the duration of germinal center (GC) reactions; and maintaining long lived plasma cells (PCs) in the bone marrow. Refer to Section “Tissue Responses and Effector Functions: The Outcomes of NF-κB2 Signaling in Response to BAFF” of text for further details.
