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… WebFeb 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).
