Fas ligand or FasL is a homotrimeric type II transmembrane protein that belongs to the tumor necrosis factor (TNF) family. It signals through trimerization of FasR, which spans the membrane of the target cell. This trimerization usually leads to apoptosis, or programmed cell death. Soluble Fas ligand is generated by cleaving membrane-bound FasL at a conserved cleavage site by the external matrix metalloproteinase MMP-7.

WebThe association of intracellular FasL with two populations of LGs, as documented in NK cells , may account for these discrepancies. FasL is targeted to MVB, where it localises together with APO2L/TRAIL both at the limiting membrane and in CD63 + intraluminal vesicles (ILV) that are released into the synaptic cleft as EVs (8, 9, 48, 54). law works clinic network report 2020WebFasL is expressed in the developing nervous system, brain, and spinal cord, as well as the submaxillary gland. Abundant expression of FasL in the developing brain may contribute to the immune-privileged status of this tissue by protecting neural tissue from inappropriate attack by Fas-bearing T cells (Griffith et al., 1995).
