  • Title: Different roles of IgG and complement receptors in phagocytosis by polymorphonuclear leukocytes.
    Author: Mantovani B.
    Journal: J Immunol; 1975 Jul; 115(1):15-7. PubMed ID: 1151058.
    Abstract:
    The functions of IgG and complement receptors in phagocytosis of immune complexes by mouse polymorphonuclear leukocytes were examined by in vitro experiments. The immune complexes were sheep red cells (E) sensitized with IgG antibody (EA) or with antibody and complement (EAC). Inhibition experiments with Fab fragments of rabbit IgG antibody anti-mouse IgG have shown that the complement receptor is primarily involved in the attachment phase, whereas participation of the IgG receptor is necessary for inducing the mechanism of phagocytosis. The possible relevance of these findings for the in vivo mechanism of defense infection, and for the control of antibody synthesis is discussed.
