Popis: To produce antigen-presenting cells (APC) from tumor cells of patients with acute leukemia and to induce autologous cytotoxic tumor-specific T-lymphocytes in vivo and in vitro.Culture examinations, flow cytofluorometry were made in 3 patients with acute myeloid leukemia (AML) and 1 patient with acute lymphoblastic leukemia (ALL).Culturing of blast cells in the presence of growth factors produced APC in 4 patients with acute leukemia. The use of fibronectin layer with added collagen proved most effective for the above production. In culture, APC induced autologous tumor-specific T-lymphocytes which selectively lysed tumor cells. Pilot clinical trial was made of dendritic cells suspension in a patient with resistant AML.A new perspective immunotherapy of acute leukemia is proposed.
