Leukemic dendritic cells (DC) were induced from the peripheral blood (PB) or bone marrow (BM) of leukemia patients by culture with (i) GM-CSF + IL-3 (neutral condition); (ii) GM-CSF + IL-3 + IL-12 + IFN-gamma (type 1-condition); or (iii) GM-CSF + IL-3 + IL-4 (type 2-condition). Although leukemic cells rapidly differentiated into adhesive leukemic DC in all culture conditions, type1-conditions were the most suitable for inducing leukemic DC expressing high levels of HLA and costimulatory molecules. Addition of IL-2 after 2 days of culture induced a preferential growth of minor T cell populations interacting with leukemic DC. In particular, IFN-gamma-producing CD4+ Th1 cells were efficiently expanded in type 1 culture conditions but nor in neutral or type 2-conditions. However, CD4+ T cells expanded in neutral conditions showed Th1-like functions if they were pulsed with IFN-gamma for 2 days before harvest. Such Th1 cells produced IFN-gamma and exhibited cytotoxicity in response to autologous leukemia cells. We further demonstrated that IFN-gamma production of leukemia-specific Th1 cells was blocked by anti-HLA-DR mAb. Thus, we established a novel culture system for inducing leukemia-specific Th1 cells.
