background: unrestricted somatic stem cells (ussc) are cord blood stem cells that have been considered as candidates for the regulation of immune responses. therefore, potential exists for their use in the suppression of immune response after transplantation surgery. objective: the aim of this study was evaluation of the effect of ussc on mixed lymphocyte reaction (mlr) as a model for graft rej...

The mixed lymphocyte reaction is characterized by proliferation and generation of specifically cytotoxic effector lymphocytes. These two phases of the mixed lymphocyte reaction have been shown to be mediated by distinct subpopulations of thymus-derived cells. The current investigation demonstrates that combinations of cells from thymus and lymph nodes of CBA mice exhibit synergism with respect ...

BACKGROUND: It is known that during normal pregnancy and after immunotherapy blocking antibodies are developed, these antibodies inhibit mixed lymphocyte reaction and are also anti-mitogenic in nature. Mixed lymphocyte reaction blocking antibodies are specific to the husband's lymphocytes. In the present study an attempt has been made to characterize the mixed lymphocyte reaction blocking antib...

NISHIHIRA, T. and FUJII, G. Mixed Lymphocyte-Platelet Lymphocyte-Kidney Cell and Lymphocyte-Liver Cell Reactions in Rats. Tohoku J. exp. Med., 1972, 108 (1), 1-7 The lymphocyte-platelet reaction (MLPR) in various donor recipient combinations in rats showed a nearly coincident relationship with the mixed lymphocyte culture reaction (MLC). The kidney cells had not enough stimulating effect agains...

The autologous mixed lymphocyte reaction (auto-MLR) measures the ability of non-T cells to stimulate autologous T cells to proliferate in tissue culture. The auto-MLR was studied in 1 1 patients with autoimmune thrombocytopenic purpura (ATP). Seven patients had decreased auto-MLR. which averaged 4440 ± 3364 cpm (SEM) compared to 1 5.360 ± 6905 cpm for simultaneously studied controls. The averag...

Mixed lymphocyte reactions occur when mouse spleen cell populations depleted of thymus-derived (T) lymphocytes are cultured with allogeneic target cells inactivated by mitomycin C or X irradiation, and when F(1) hybrid responder cells are cultured with inactivated parental target cells. These responses might be interpreted as indicating that T lymphocytes are not required for responsiveness and...
