[Suppression of the formation of cells secreting antibodies and antigen-dependent nonspecific immunoglobulins in mice receiving isologous antierythrocyte immunoglobulins].

Mice injected with syngeneic cellulose-conjugated immunoglobulins (Ig) containing antibodies to sheep red blood cells (SRBC) develop a specific non-responsiveness to SRBC. Such animals demonstrate a sharp decrease not only in the formation of anti-SRBC antibody producers but also of the cells secreting antigen-dependent nonspecific Ig. The inhibition of both these processes is antigen-specific. It is suggested that inhibition of the cells forming antigen-dependent nonspecific Ig is due to suppression of either hypothetic inductors or precursors of these cells expressing an idiotype spectrum similar to that of anti-SRBC antibody producers.
