Abstract:
The BAFF family of receptors and ligands controls B cell homeostasis and selection. Recent studies reveal distinct sources and roles for systemic versus locally produced BAFF. Moreover, the notion that differential BAFF receptor expression patterns establish independent homeostatic and selective niches has been strengthened. Finally, unique roles for BAFF family members in the regulation of antigen experienced and innate B cell subsets have been revealed. Herein, we overview current knowledge in these areas, emphasizing recent findings that inform these ideas.

B Cell Activation and Differentiation
When naive B cells encounter a specific antigen that can bind to the B cell receptor (BCR) on their surface, they undergo sensitization to respond to the antigen's presence. Sensitization begins with...
Diversity of Antigen Receptors
Before encountering any antigen, lymphocytes express these receptors. On B cells, the antigen receptor is a membrane-bound antibody molecule called BCR; on T cells, it is a T cell receptor or TCR. B and T cell receptors are composed of two...
