Background: Fas/TNFRSF6/CD95

Fas (fibroblast associated; also known as APO-1 or CD95) is a member of the death receptor subfamily of the TNF receptor superfamily and is designated TNFRSF6 (1-3). The human Fas precursor is 335 amino acids (aa) in length, and contains a 25 aa signal peptide, a 148 aa extracellular domain (ECD), a 17 aa transmembrane sequence, and a 145 aa cytoplasmic region. The ECD possesses three cysteine-rich TNFR repeats, while the cytoplasmic region contains one death domain (DD) that is required for the transduction of apoptotic signals (4). Cynomolgus monkey Fas ECD shares 91% aa sequence identity with human Fas ECD. A human Fas isoform of 314 aa that lacks the transmembrane sequence is secreted by resting lymphocytes, while isoforms of 149, 132, 103 and 86 aa that also lack the DD and show substitutions for parts of the TNFR repeats are less prominently expressed (4-6). All five isoforms block the extrinsic apoptosis pathway induced by Fas ligand binding. Fas ligand (FasL; also TNFSF6) is a type II transmembrane protein that belongs to the TNF family and is expressed on activated T-cells, NK cells, and cells found in immune privileged sites. Alternatively, FasL is also shed as a soluble form (2, 6). Engagement of FasL induces oligomerization of preformed Fas trimers (1, 2). This activated receptor complex recruits the adaptor molecule FADD to form the Death-Inducing Signaling Complex (DISC). Upon activation, caspases in the DISC initiate the apoptotic signaling cascade (7). Fas is prominent in epithelial cells, hepatocytes, activated mature lymphocytes, virus-transformed lymphocytes and tumor cells. It is an essential mediator in the activation-induced death of T lymphocytes that terminates the immune reaction (1, 2, 8). In immune-privileged tissues, infiltrating Fas-bearing lymphocytes and inflammatory cells are killed by FasL engagement (9). Both humans and mice with genetic defects in Fas accumulate abnormal lymphocytes and develop systemic autoimmunity (1-3). The Fas pathway also appears to intersect with the BIM (mitochondrial/intrinsic) apoptosis pathway (1).
