ABSTRACT
Immunosuppressive activities have been found in the culture supernatant of four leukemiacell lines and in the sera of four patients with leukemia. The inhibitors suppressed PHA-p in-duced lymphocytes proliferation and IL-2 production and responsiveness of T cells to IL-2, butno inhibitory activity was observed in the culture supernatant of 2BS cell line or in the sera ofnormal humam. The culture supernatant of tumor cell lines was not cytoxic. The result of PAGEshows the molecular weight of TDSF from HL-60 human promyelocytic leukemia is about87KD. It is protein in chemical nature. The synthesis and sercretion of TDSF were partially in-hibited by drugs of anti-acute non-lymphocytic leukemia.
