The TNF family member BAFF is a fundamental survival factor for B cells. BAFF binds to three receptors, only one of which, BAFF-R, does not cross-react with the BAFF-related ligand APRIL. The survival function of BAFF on B cells is mediated mainly by BAFF-R and is particularly effective in transitional B cells. BAFF depletion leads to a considerable decrease in mature B cells, without apparent effect on B cell genesis. Consistently, BAFF overexpression results in an expanded B cell compartment and autoimmunity in mice. Elevated amounts of BAFF can be found in the serum of patients suffering from autoimmune diseases. The BAFF system is a promising target for the treatment of autoimmune diseases.
