Abstract
The modulating effects of passive antibodies on both delayed hypersensitivity to the carrier and antibody synthesis to carrier and hapten determinants were studied in guinea pigs. Animals were injected with antibodies directed against either the carrier or the hapten prior to immunization with the hapten-carrier conjugate in Freund's complete adjuvant. Anti-hapten antibodies have been shown to have an enhancing effect on delayed hypersensitivity to the carrier and a suppressive effect on antibody synthesis to the hapten. In this experiment, anti-carrier anti-bodies seemed to have had no effect on delayed hypersensitivity to the carrier and on antibody synthesis to the hapten.
