Background

B-cell activating factor (BAFF), also known as BLyS, TALL-1, THANK, and TNFSF13B, is a 32 kDa transmembrane glycoprotein in the TNF ligand superfamily. It is involved in multiple aspects of immune system regulation, particularly towards B cells (1, 2). 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 (3, 4). Within aa 134-285 of the ECD, human BAFF shares 72% aa sequence identity with mouse BAFF. It can be expressed as a homo-oligomer or as a heteromer in association with the related TNFSF member APRIL (4, 5). A 18 kDa fragment containing the TNF-like domain can be released by proteolysis between Arg133 and Ala134 (4). Soluble BAFF is stored intracellularly in neutrophils and released upon inflammatory stimulation (6). Alternative splicing generates an isoform termed deltaBAFF that lacks 19 aa between the proteolytic cleavage site and the TNF-like domain. deltaBAFF can form heteromers with BAFF and negatively regulates BAFF function (7). BAFF is produced by many hematopoietic cell types including monocytes, macrophages, neutrophils, dendritic cells, and T cells and also by adipocytes (1, 2, 8). Both BAFF and APRIL are functional ligands for the TNF receptor superfamily members BCMA and TACI, and BAFF additionally binds and signals through BAFF R (9, 10). All three receptors are primarily expressed by B cells (10). BAFF plays a critical role in the development and survival of B lineage cells (2, 11, 12). Mice that overexpress BAFF exhibit elevated B cell numbers, increased formation and size of germinal centers, and symptoms of autoimmunity (13). Soluble BAFF is elevated in B cell malignancies, autoimmunity, and other immune disorders (1). In addition, BAFF co‑stimulates T cell activation, promotes a Th1 biased immune response, and promotes the expansion of Treg cells (14‑16). BAFF also promotes monocyte survival, proinflammatory cytokine secretion, and differentiation to macrophages (17).
