Abstract
Cell surface receptors for human γG antibodies directed against bacterial antigens were demonstrated on human neutrophils using an in vitro bacteriocidal-phagocytic assay. These results were confirmed by adherence of sensitized erythrocytes to monolayers of neutrophils or monocytes. Erythrocytes sensitized indirectly with antibacterial γG antibodies after passive sensitization with bacterial antigens adhered to both neutrophils and monocytes. Erythrocytes sensitized directly with conventional anti-D γG antibodies adhered only to monocytes, while those sensitized with the hyperimmune anti-CD γG antibody Ripley adhered to both monocytes and neutrophils. Adherence of anti-Rh or antibacterial γG antibodies to monocytes and neutrophils could be inhibited by whole γG, myeloma globulins of the γ1 or γ3 subclasses, or Fc fragments, but not by Fab fragment.
