WebApr 28, 2014 · Activated cytotoxic T lymphocytes (CTLs) induce and express high levels of FasL, but the effects of Fas activation initiated by FasL in CTLs on apoptosis-resistant tumor cells remain largely unclear. 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… graphite contacts

"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. " - Ctl fasl

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.
