Mononuclear cells and their fractions which were prepared from spleens removed at the time of surgery for gastric cancer were treated with mitomycin C and their effect on autochthonous peripheral blood lymphocyte responses to PHA-P and Con A was assessed in coculture experiments. Splenic mitomycin C treated mononuclear cells from certain gastric cancer patients were found to have suppressor activity on peripheral blood lymphocyte responses to PHA-P and Con A and the cells with the activity were either plastic dish adherent cells or T-enriched cells alone or both of them. The suppressor activity were more frequently detected in patients with stage IV disease and the patients with the activity tended to exhibit more decreased cell mediated immunocompetence than those without it. Splenic mitomycin C treated mononuclear cells from certain gastric cancer patients were also found to have augmenting activity on peripheral blood lymphocyte responses to PHA-P and the cells with the activity were either plastic dish adherent cells or T-enriched cells or all of plastic dish adherent cells and T- and B-enriched cells.

UI MeSH Term Description Entries
D007108 Immune Tolerance The specific failure of a normally responsive individual to make an immune response to a known antigen. It results from previous contact with the antigen by an immunologically immature individual (fetus or neonate) or by an adult exposed to extreme high-dose or low-dose antigen, or by exposure to radiation, antimetabolites, antilymphocytic serum, etc. Immunosuppression (Physiology),Immunosuppressions (Physiology),Tolerance, Immune
D008213 Lymphocyte Activation Morphologic alteration of small B LYMPHOCYTES or T LYMPHOCYTES in culture into large blast-like cells able to synthesize DNA and RNA and to divide mitotically. It is induced by INTERLEUKINS; MITOGENS such as PHYTOHEMAGGLUTININS, and by specific ANTIGENS. It may also occur in vivo as in GRAFT REJECTION.

D010835 Phytohemagglutinins Mucoproteins isolated from the kidney bean (Phaseolus vulgaris); some of them are mitogenic to lymphocytes, others agglutinate all or certain types of erythrocytes or lymphocytes. They are used mainly in the study of immune mechanisms and in cell culture.

D003208 Concanavalin A A MANNOSE/GLUCOSE binding lectin isolated from the jack bean (Canavalia ensiformis). It is a potent mitogen used to stimulate cell proliferation in lymphocytes, primarily T-lymphocyte, cultures.
