Abstract
Scanning electron microscopy demonstrated that cytophilic antibody (Cab) attached to the [mouse] macrophage surface substantially changes the cell surface relief. Diffuse loss of surface structure was accompanied by diminished ability to interiorize opsonized sheep erythrocytes and to damage non-specifically bystanding target cells (chicken erythrocytes). Cross-linking of Cab on the macrophage surface by antigen or antibody partially restores macrophage membrane activity.
