Genetic restrictions for the induction of suppressor T cells by hapten-modified lymphoid cells in tolerance to 1-fluoro-2,4-dinitrobenzene contact sensitivity. Role of the H-2D region of the major histocompatibility complex. 1978

S D Miller, and M S Sy, and H N Claman

Genetic restrictions governing the induction and expression of suppressor T cells (Ts) in tolerance to 1-fluoro-2,4-dinitrogenzene (DNFB) contract sensitivity were studied. Tolerance was induced by using 2,4-dinitrophenyl (DNP)-modified lymphoid cells (DNP-LC) as tolerogen. Two kinds of Ts were found-those produced by DNP-LC syngeneic to the donor of the Ts (syninduced Ts), and those produced by DNP-LC allogeneic to the donor of Ts (alloinduced Ts). Studies employing congenic resistant mouse strains indicated that recognition of DNP-modified-major histocompatibility region determinants on the tolerogenic DNP-LC was essential for the induction of both types of Ts. Non-H-2 genetic background was irrelevant to Ts induction. Mapping studies indicated that induction of both syninduced and alloinduced Ts was associated with recognition of DNP-modified-MHC region determinants which map to the right of the H-2G region (i.e., H-2D gene products). Tolerization of donor mice with DNP-LC which were H-2D region compatible, but not with H-2K or I region compatible DNP-LC, was both sufficient and required for the induction of hapten-specific syninduced Ts. Tolerization of donor mice with DNP-LC which were incompatible only at the H-2D region was sufficient for the induction of alloinduced Ts. These Ts were capable of suppressing recipient mice only if the recipients shared the H-2D region with the strain providing the DNP-LC tolerogen, and were not capable of suppressing recipients sharing all but the H-2D region with the tolerogen.

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
D007111 Immunity, Cellular Manifestations of the immune response which are mediated by antigen-sensitized T-lymphocytes via lymphokines or direct cytotoxicity. This takes place in the absence of circulating antibody or where antibody plays a subordinate role.

D007165 Immunosuppression Therapy Deliberate prevention or diminution of the host's immune response. It may be nonspecific as in the administration of immunosuppressive agents (drugs or radiation) or by lymphocyte depletion or may be specific as in desensitization or the simultaneous administration of antigen and immunosuppressive drugs.
