Reaginic antibody formation in the mouse. VII. Induction of suppressor T cells for IgE and IgG antibody responses.
Intravenous injections of urea-denatured ovalbumin (UD-OA) into OA-primed high responder mice suppressed the antibody response not only to the priming antigen but also to subsequent immunization with dinitrophenyl derivatives of OA (DNP-OA). The transfer of normal spleen cells or OA-primed spleen cells into UD-OA-treated animals did not restore the capacity of responding to DNP-OA to form anti-DNP IgE and IgG antibodies. The transfer of splenic T cell fraction from the UD-OA-treated animals into normal syngeneic mice diminished both IgE and IgG antibody responses of the recipients to DNP-OA. The B cell-rich fraction from the same donors failed to affect the anti-hapten antibody response and enhanced anti-cancer (OA) IgG antibody response of the recipients. It was also found that the transfer of T cell-rich fraction of OA-primed spleen cells failed to suppress antibody response of the recipients to DNP-OA. The results indicated that spleen cells of UD-OA-treated mice contained suppressor T cells which are distinct from helper cells. Suppressive activity of T cells in the UD-OA treated animals was specific for OA. The transfer of the T cell-rich fraction failed to suppress anti-DNP antibody response of the recipients to DNP-KLH.
