title: Carrier function in anti-hapten antibody responses. IV. Experimental conditions for the induction of hapten-specific tolerance or for the stimulation of anti-hapten anamnestic responses by "nonimmunogenic" hapten-polypeptide conjugates.
abstract: Administration of nonimmunogenic 2,4-dinitrophenyl (DNP) conjugates of copolymers of D or L-glutamic acid and lysine (GL) induces hapten-specific tolerance in nonimmune and DNP-ovalbumin-primed strain 13 guinea pigs. This tolerant state is evidenced by depressed anti-DNP antibody synthesis in response to challenge with DNP-ovalbumin and by a diminished frequency of DNP-specific antigen-binding cells and of anti-DNP antibody-secreting cells. Such a nonimmunogenic compound (DNP-D-GL) will nevertheless elicit a DNP-specific anamnestic antibody response when administered at an appropriate time to DNP-ovalbumin-primed guinea pigs undergoing a graft-versus-host reaction. These experiments are discussed in terms of a two-cell theory of stimulation of antibody responses.
