WebMar 29, 2024 · Overexpression of human FasL in pig islets inhibits CTL cytotoxic T cell xenocytotoxicity. The amount of CaM recruited into the DISC was increased after Fas-stimulation, a finding confirmed by immunofluorescent analysis that demonstrated increased membrane co-localization of CaM and Fas upon Fas-stimulation. 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 ...

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.
