[Effect of suppressor cells on the formation of immunologic memory in mice of various strains].
The mice of different lines were immunized twice with low doses (10(6) of sheep red blood cells (SRBC) at a 7-day interval. The immune spleen cells (ISC) from syngeneic and allogeneic mice preliminarily (14 days before) given SRBC (5 . 10(8) were transplanted into the animals at varying times before or after primary antigen administration. It was discovered that the administration of the ISC from CBA and DBA/2 mice to syngeneic mice 1 or 2 days after the priming drastically lowers the production of antibody-forming cells in the recipients in response to the repeated antigen injection. The ISC from C57BL/6 mice provided low suppressor effect. ISC transplantation one, three or six days after the priming exerted no effect on the height of the secondary immune response. Suppression of antibody formation was also obtained in the allogeneic combinations CBA ISC leads to leads to C57BL/6 and DBA/2 ISC leads to CBA. It is concluded that the spleen cells from mice immunized with SRBC are capable to suppress the development of the immunological memory of SRBC.
