Comparative activities of A24 and IL-2α on cell proliferation in acute and chronic forms of ATL. Peripheral blood leukocytes from healthy individuals (A), and chronic (B) or acute (C) forms of ATL were incubated with PHA and IL-2 for 72 hours with A24, anti–IL-2Rα, or both. Proliferation of these cells was then measured by [3H]-thymidine incorporation. Data are means ± SD of one of at least 3 separate experiments with 4 acute and 3 chronic ATL patients.
