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. WebAug 28, 2024 · Diverse FasL sources can induce T cell–associated Fas signaling and resultant apoptosis. Abnormally high FasL transcript levels were recently reported for a majority of tumors (Yamamoto et al., 2024), and higher FasL protein expression is commonly associated with worsened prognosis (Peter et al., 2015). open mic hudson valley

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. WebFasL 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). The embryonic ... ip address and countryWebIn addition, there have been no reports concerning Fas-mediated apoptosis in human melanocytes in vitro.
