Background: Fas/TNFRSF6/CD95

Tumor Necrosis Family Receptor (TNFR) superfamily member Fas, also known as CD95, APO-1, and TNFRSF6, is a 40-50 kDa type I transmembrane glycoprotein that is traditionally considered a death receptor but also functions in non-apoptotic signaling (1-4). The human Fas/TNFRSF6/CD95 protein is encoded by the FAS gene which contains 9 exons and is located on chromosome 10 (10q23.3-4) (1,2). The mature canonical Fas/TNFRSF6 protein isoform is 335 aa in length, which includes the signal sequence, and has a theoretical molecular weight of 37.7 kDa (1,5). The protein contains an extracellular domain (ECD) consisting of three calcium rich domains (CRDs), a transmembrane domain (TM), and an intracellular domain (ICD) comprised of a calcium-inducing domain (CID) and characteristic dead domain (DD) (1,2,5,6). The Fas protein is expressed on the plasma membrane of activated lymphocytes as a homotrimer formed via CRD1 interactions (1,2,3,6). The DD is crucial for apoptotic signaling which is triggered by the Fas receptor binding its ligand, Fas ligand (FasL) (1,2,6,7). Upon Fas-FasL interaction, the DD recruits an adapter protein Fas-associated DD (FADD) and procaspase-8, generating the death-inducing signaling complex (DISC) (1-4,6-8). Formation of DISC activates caspase-8 and leads to cleavage of caspase-3, initiating a caspase-signaling cascade and cell death (1-4,6-8).

Fas-FasL-mediated apoptosis is important in immune homeostasis and removal of autoreactive T cells, autoreactive B cells, cytotoxic natural killer (NK) cells, and more (1,2,7). Dysfunction and mutations in the Fas receptor and the Fas-FasL signaling axis is associated a loss of apoptotic signaling and removal of autoreactive cells, which correlates with several autoimmune diseases including systemic lupus erythematosus (SLE), autoimmune lymphoproliferative syndrome (ALPS), and multiple sclerosis (MS) (1-4,6,7). In addition to apoptosis and cell death signaling, FasL/TNFRSF6/CD95 mediates other pathways involved in proliferation, survival, and differentiation (3,4,6,8). More specifically, Fas has been shown to activate the NF-kappaB pathway, driving innate immunity which includes IL-1beta production and functioning in host defense (3,4,6,8). Fas is also involved in adaptive immunity playing a role in co-stimulation of CD4+ and CD8+ T cell activation as well as precocious differentiation of naive cells to effector memory T cells (3,4,6). Differentiation into effector memory T cells shows protection against autoimmunity but also limits antitumor response to a form of cancer immunotherapy called adoptive cell transfer (ACT) (3,4). The non-apoptotic roles of the Fas/TNFRSF6/CD95 receptor highlight its potential as a target for both treating autoimmune diseases and in cancer immunotherapy (3,4).
