WebScope Note. Cytolytic lymphocytes with the unique capacity of killing natural killer (NK)-resistant fresh tumor cells. They are INTERLEUKIN-2-activated NK cells that have no MAJOR HISTOCOMPATIBILITY COMPLEX restriction or need for antigen stimulation. LAK cells are used for ADOPTIVE IMMUNOTHERAPY in cancer patients. WebOct 15, 1992 · The killing mediated by cytotoxic T lymphocytes (CTL) represents an important mechanism in the immune defence against tumors and virus infections. The lytic mechanism has been proposed to consist of a polarized secretion of granule-stored molecules, occurring on effector-target cell contact. By electron microscopy, membrane …
