Nafici 2015 10 03 The immunosuppressive effect of antimacrophage serum (AMS) on the primary immune response of mice to sheep red blood cells (SRBC) was studied. AMS, given before a small dose of antigen, abrogated the immune response. Transplantation of normal, galss-adherent macrophages enabled AMS-treated animals to respond to SRBC, while administration of lymph node lymphocytes did not reveres AMS - induced immunosuppression significantly. https://ijph.tums.ac.ir/index.php/ijph/article/view/2473 https://ijph.tums.ac.ir/index.php/ijph/article/download/2473/2453
