BAFF, a member of the TNF family, is a fundamental survival factor for transitional and mature B cells. Mature human BAFF consists of a 46 amino acid (aa) cytoplasmic domain, a 21 aa transmembrane segment, and a 218 aa extracellular domain (ECD) with a stalk region and one TNF-like domain. Within aa 134-285 of the ECD, human BAFF shares 72% aa sequence identity with mouse BAFF. BAFF binds to three receptors, BAFF-R, transmembrane activator and calcium modulator and cyclophilin ligand interactor (TACI), and B cell maturation Ag (BCMA). BAFF receptors were strongly expressed in situ in primary central nervous system (CNS) lymphomas. In addition, BAFF costimulates T cell activation, promotes a Th1 biased immune response, and promotes the expansion of Treg cells. BAFF also promotes monocyte survival, proinflammatory cytokine secretion, and differentiation to macrophage.
