Immunologic suppression after oral administration of antigen. I. Specific suppressor cells formed in rat Peyer's patches after oral administration of sheep erythrocytes and their systemic migration. 1978

J A Mattingly, and B H Waksman

Rats given 10(10) sheep erythrocytes (SRBC) orally were found to contain specific suppressor cells to SRBC in their Peyer's patches (PP) and mesenteric lymph nodes (MLN) after 2 days of feeding. After 4 days of feeding, similar suppressor cells were found in the thymus and spleen, but they were missing in the PP or MLN. These suppressor cells effectively blocked IgM and IgG plaque-forming cell responses to SRBC in Mishell-Dutton cultures and delayed-type-hypersensitivity responses to SRBC when transferred to syngeneic recipients, but they did not affect responses to horse erythrocytes. The orally induced specific suppressor cells appeared to be T2 cells since their activity was eliminated by in vivo treatment of SRBC-fed rats with anti-rat lymphocyte serum but not by adult thymectomy. Because carrageenan partially relieved the suppression observed in culture, the actual suppressive mechanism may also involve a macrophage.

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.
