IL-10 is a regulatory cytokine of both T cells and monocytes. We have investigated the ability of IL-10 to regulate responses to alloantigens in vitro and in vivo. Addition of IL-10 to mixed lymphocyte cultures profoundly decreased the proliferation and IL-2 production by donor B10.BR cells stimulated with CBA cells expressing minor histocompatibility antigens. Administration of IL-10 for a period of 2 weeks after bone marrow transplantation decreased the expansion of CD4+ and CD8+ donor T cells. In addition, splenocytes from BMT mice treated with IL-10 secreted less IFN-gamma after stimulation with Con A in vitro. The suppression of the mitogen-driven proliferative response of lymphocytes from the IL-10-treated group could also be reversed with significantly less anti-IFN-gamma antibody than for saline-treated controls. However, treatment with IL-10 was not sufficient to alter significantly the clinical course of graft-versus-host disease in CBA recipient mice as assessed by survival, weight loss, and splenomegaly. The results suggest that exogenous IL-10 suppresses the afferent Th1 response in a graft-versus-host reaction but does not significantly diminish the effector stage of graft-versus-host disease.

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.

D008810 Mice, Inbred C57BL One of the first INBRED MOUSE STRAINS to be sequenced. This strain is commonly used as genetic background for transgenic mouse models. Refractory to many tumors, this strain is also preferred model for studying role of genetic variations in development of diseases.
