Stimulation of the in vivo dinitrophenyl antibody response to the DNP conjugate of L-glutamic acid60-L-alanine30-L-Tyrosine10 (GAT) polymer by a synthetic adjuvant, muramyl dipeptide (MDP): target cells for adjuvant activity and isotypic pattern of MDP-stimulated response

Abstract

Specific anti-dinitrophenyl (DNP) response to DNP-conjugated L-glutamine60-L-alanine30-L-tyrosine10 (DNP-GAT) was obtained in GAT-responder mice by using synthetic N-acetylmuramyl-L-alanyl-D-isoglutamine (MDP) as adjuvant. Significant levels of anti-DNP antibodies were observed during a secondary response to DNP-GAT, when both antigen and MDP were used for priming. In this system, MDP was able to prime the carrier-specific T cells but not the hapten specific B cells. The study of the isotypic pattern of the anti-DNP response shows that MDP stimulates only the appearance of specific anti-DNP IgG1 plaque-forming cells. Anti-DNP plaque-forming cells were stimulated in animals primed with DNP-GAT in Freund's complete adjuvant or in Maalox-pertussis and used as control IgG1, IgG2a, and IgG2b.
