[Natural immune response and immunological memory in the effects of a 2d unrelated antigen]

In combined administration of two nonaffiliated erythrocytic antigens there can be seen both depression and stimulation of the immunological response to the participating antigens. The end result of the interaction depended on the "power", the dose and the order of administration of the antigens. Distribution of the antigen in the animals whose immune response was depressed as a result of preliminary administration of the nonaffiliated antigen remained unchanged. The factor determining the effect on the immunological response to the other antigen did not serve as an antibody.
