title: Interleukin-2 can induce proliferation of leukemic B-cells in prolymphocytic leukemia.
abstract: In a case of prolymphocytic leukemia (PLL), receptors for interleukin-2 (IL-2R) were demonstrated by immunofluorescence with a monoclonal antibody against IL-2R. Highly purified leukemic B-cells, cultured in vitro with recombinant IL-2 (r-IL-2), responded to IL-2 with a marked increase of DNA-synthesis. Both spontaneous and r-IL-2-induced proliferation of leukemic cells were totally abrogated by the anti-IL-2R monoclonal antibody.
