A method for generating antigen-specific cytotoxic cells with activity against ovarian cancer cells

摘要

FIELD: biotechnologies.;SUBSTANCE: an in vitro generation method of antigen-specific cytotoxic cells with activity against ovarian carcinoma cells is proposed. Simultaneously, a non-adhesive fraction of mononuclear cells (MNC) and mature dendritic cells (DC) are cultivated in presence of recombinant human interleukine-12 and recombinant human interleukine-18. MNC are extracted from peripheral blood of patients having ovarian carcinoma. Mature DC are obtained from monocytes of adhesive MNC fraction after two-day cultivation, and first, activation by lysate of autologous ovarian carcinoma cells, and then maturation of DC loaded with lysate during one day in presence of recombinant human TMF-α (tumor necrosis factor).;EFFECT: use of the invention provides reduction of a stage for obtaining mature DC, in vitro increases cytotoxicity of antigen-specific cytotoxic cells with antitumor activity and provides an immune response via T-helper to type 1 in respect to ovarian carcinoma, which can be used in ovarian carcinoma therapy.;2 tbl
