Abstract
The TNF family ligands BAFF (also called BLyS) and APRIL regulate lymphocyte survival and activation. BAFF binds to three receptors, BAFF-R, TACI and BCMA, whereas APRIL interacts with TACI, BCMA and proteoglycans. The contribution of BAFF and APRIL to B-cell and plasma-cell survival, CD154 (CD40L)-independent antibody isotype switching, germinal center maintenance, T-dependent and T-independent antibody responses, and T cell co-stimulation are relatively well understood. Constitutive BAFF produced by stromal cells determines the size of the peripheral B cell pool, whereas inducible BAFF produced by myeloid and other cells supports local survival of B lymphocytes and can be associated with development of autoimmunity when deregulated.Entities:
