Suppressor T cells for IgE and IgG in Peyer's patches of mice made tolerant by the oral administration of ovalbumin. 1978

J Ngan, and L S Kind

A single oral dose of ovalbumin (Ov) resulted in inhibition of IgE formation in mice subsequently immunized i.p. with Al(OH)3-Ov. Repeated feeding of Ov (on alternate days for 2 weeks) induced the formation of detectable suppressor cells in Peyer's patches and spleen. Suppression was demonstrated by the ability of adoptively transferred Peyer's patch or splenic lymphocytes from Ov-fed tolerant mice to inhibit IgE formation in Ov-immunized syngeneic recipients. Suppressor cells could be induced by feeding mice as little as 100 microgram of Ov on alternate days for 2 weeks. Suppression was specific and Peyer's patch lymphocytes were shown to be more effective suppressors than splenic lymphocytes.

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
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.
