ABSTRACT
Peripheral blood mononuclear cells (PBMNC) isolated from patients with acute leukemia (AL) and from normal controls were cultured in medium containing 1000 units/ml of recombinant interleukin 2 (IL-2). Marked LAK activity was induced on the third culture day in the normal controls,, with the highest cytotoxicity appearing between day 3 and 5 whereas induction of LAK activity in the AL patients began on the 5th day of culture, with the peak level appearing at day 15, showing that the peak of LAK activity was significantly delayed in AL. LAK cells surface phenotyping tests showed that CD8+ and CD16+ positive cells began to increase significantly from day 5 and reached the highest level at week 3, whereas CD4+ subclass began to decrease on day 5 and dropped to the nadir at week 3. The proportion of CD8+ and CD16+ cells were positively cor related with LAK activity, but, that of the CD4+ cell was inversely related with the LAK activity.
