This basic study was performed to determine whether the anti-tumor effect of lymphocytes obtained from the peripheral blood of a tumor bearing host can be increased when cultured in vitro with Mitomycin C (MMC)-treated AH109A tumor cells, using interleukin-2 (IL-2). Donryu rats were used as tumor bearing hosts. The following results were obtained. Weak anti-tumor activity of lymphocytes was noted 7 days after lymphocytes were cultured in the medium to which only IL-2 was added. Anti-tumor activity was augmented by adding antigen (MMC treated tumor cells) to the above (1). Anti-tumor activity was further augmented by adding to (2) above antigen presenting cells such as intraperitoneal exudate macrophages or peripheral hole leukocytes. Anti-tumor activity of lymphocytes was detected when IL-2 and MMC treated antigen were added to the peripheral hole leukocytes containing the lymphocytes.

D007959 Lymphocyte Culture Test, Mixed Measure of histocompatibility at the HL-A locus. Peripheral blood lymphocytes from two individuals are mixed together in tissue culture for several days. Lymphocytes from incompatible individuals will stimulate each other to proliferate significantly (measured by tritiated thymidine uptake) whereas those from compatible individuals will not. In the one-way MLC test, the lymphocytes from one of the individuals are inactivated (usually by treatment with MITOMYCIN or radiation) thereby allowing only the untreated remaining population of cells to proliferate in response to foreign histocompatibility antigens.

D008214 Lymphocytes White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS. Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell
D008264 Macrophages The relatively long-lived phagocytic cell of mammalian tissues that are derived from blood MONOCYTES. Main types are PERITONEAL MACROPHAGES; ALVEOLAR MACROPHAGES; HISTIOCYTES; KUPFFER CELLS of the liver; and OSTEOCLASTS. They may further differentiate within chronic inflammatory lesions to EPITHELIOID CELLS or may fuse to form FOREIGN BODY GIANT CELLS or LANGHANS GIANT CELLS.

D008937 Mitomycins A group of methylazirinopyrroloindolediones obtained from certain Streptomyces strains. They are very toxic antibiotics used as ANTINEOPLASTIC AGENTS in some solid tumors. PORFIROMYCIN and MITOMYCIN are the most useful members of the group.
