The aim of this study was to investigate the role of Fc? receprors (Fc?R) in vitro, in phagocytosis of hormone-antibody complexes formed after immunization with the mutant hCG?(R68E). Native, FITC labeled hCG was added to the sera from mutant hCG?(R68E) immunized rabbits. The suspensions of phagocytic cells were selectively incubated with monoclonal antibodies to Fc?RI, Fc?RII, Fc?RIII and the complement receptor 3 in order to block their functions and phagocytosis was visualized by flow cytometry. We show that the phagocytosis of immune complexes containing anti-hCG?(R68E) sera of rabbits and native hCG molecules by monocytes and neutrophils is mediated by Fc?RI(CD64) and Fc?RIII(CD16) respectively in cooperation with the complement receptor 3 (CR3).
