Reactivity of serum-armed xenogeneic macrophages to breast cancer antigens.
Sera from breast cancer patients contained cytophilic antibody which armed guinea pig peritoneal macrophages. These macrophages then exhibited specific adherence inhibition in the presence of tissue culture tumor antigens. These antigens were obtained from primary cultures of autologous or allogeneic breast cancer cells. Sera from control subjects for the most part did not induce macrophage adherence inhibition in the presence of these same antigens.
