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. csts 2000WebFeb 1, 2007 · In CTL or NK cells, FasL is delivered to and stored in the lytic granules (6--8), where the proline-rich domain in the cytoplasmic tail of FasL is the sorting signal (9).
