Abstract: | Data on the effect of various antisera on the induction of antibody formation by immune allogeneic macrophages are described. A considerable decrease in the intensity of the immune response was observed after injection both of allogeneic antiserum and of antimacrophagal serum during the first 2 days after transplantation of the allogeneic macrophages. Injection of these sera on the following days had no significant effect on the intensity of the immune response. Antierythrocytic serum prevented the accumulation of antibody-forming cells if injected at various times after transplantation of the allogeneic macrophages.Institute of Medical Genetics, Academy of Medical Sciences of the USSR, Moscow.
