WebSep 1, 1997 · CTLs are relatively more resistant than tumor targets in their susceptibility to cell-mediated cytotoxicity. 7 Also, not all Fas + target cells are susceptible to FasL-based killing. 6 Thus, it is necessary to directly test whether FasL-bearing tumor cells can kill tumor-specific CTLs. In phase two, the now functional effector CTLs destroy the target cells. This can be done in two ways. These pathways are the cytotoxic protein pathway and the Fas ligand pathway. Apoptosis is the primary mechanism for both of these pathways. One pathway is the cytotoxic protein pathway. In this pathway perforins and granzymes are taken up by the target cell. In this pathway, the perforins facilitate the entry of granule contents into th…

The principals of … 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.

It would obviously be deleterious if, for instance, CTL are to destroy antigen processing cells essential for the antibody response.
