Summary The induction of lymphokine-activated killer (LAK) cells against fresh human leukemia cells was investigated. Two thirds of the 62 leukemias examined were susceptible to the lytic effect of allogeneic IL-2 induced LAK cells in vitro. No substantial differences could be detected between myeloid or lymphoid leukemias or with regard to the FAB subtype or the immunophenotype. Culturing mononuclear cells from peripheral blood or bonemarrow of leukemia patients with IL-2 resulted in an expansion of residual large granular lymphocytes and development of cytotoxic activity. The combination of IL-2 with IFN-gamma or the presence of tumor cells during the activation process led to an enhancement of LAK cell cytotoxicity. These results suggest that LAK cells may be useful in the treatment of leukemia.
