[Effect of interferon on the immune response of mice to immunization with the cells of transplantable leukemias and sarkomas].
The treatment of cells L-1210 and MX-11 in vitro with interferon, prior to their injection to mice, caused an enhancement of specific humoral response and cytotoxic action of immune lymphocytes to Cr51 labelled target cells. The injecting of mice with allogeneic interferon-containing serum against the background of immunization with L-1210 cells produces an enhancing effect upon the immune response. Much more marked enhancing effect was observed when using syngeneic interferon-containing serum. Short-term treatment of lymphocytes, being immune to L-1210 cells, with interferon in vitro leads to the increase of their specific cytotoxicity to Cr51 labelled cells. Pre-treatment of leukemic cells with interferon would enhance their sensitivity to specific antibodies. It is suggested to use an active immunization of acute leukemia patients with allogeneic leukemic cells pre-incubated in interferon in combination with the injection of interferon-containing donor plasma.
