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). WebFASL induces apoptotic cell death. It plays a key role in the immune system homeostasis, cytotoxic T cell (CTL)-mediated killing of virally infected or transformed cells, NK cell-mediated death cell, and termination of immune responses by induction of activation-induced cell death.

"WebExpert Answer. 1-a. The CTL would not kill the target cell - TCR (T-cell receptor) expressed by CTL (cytotoxic T-lymphocyte) recognizes the MHC: antigen complex presented by the target cell. If the TCR does not recognize the MHC: antigen complex, the CTL would not be able to bind to the target cell and therefore would not be able to kill it. " - Ctl fasl

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.
