The effects of the recombinant human cytokines interleukin 2 (IL-2) and IL-7 on the proliferation of T-acute lymphoblastic leukaemia (T-ALL) cells were tested in a clonogenic assay. Highly purified leukaemic cells were obtained by immunomagnetic depletion of mature T cells and fluorescence-activated cell sorting for immature leucocyte markers (CD1, CD10, CD34). Of 9 cases tested, only 3 showed evidence of stimulation by cytokines. One was stimulated by both IL-2 and IL-7, one by IL-2 only, and the third by IL-7 alone. A further case showed proliferation without addition of cytokines. The remaining 5 cases were completely unresponsive. While both IL-2 and IL-7 are capable of stimulating leukaemic cells from some cases of T-ALL, the molecules regulating the proliferation of T-ALL cells in vitro remain to be more fully elucidated.

D008212 Lymphocyte Depletion Immunosuppression by reduction of circulating lymphocytes or by T-cell depletion of bone marrow. The former may be accomplished in vivo by thoracic duct drainage or administration of antilymphocyte serum. The latter is performed ex vivo on bone marrow before its transplantation.
