[Antibody-dependent target cell killing by a killer cell. An antibody is directed to the target by antigen-binding arms and anchors to the killer cell by an Fc receptor. Antibody-mediated target cell destruction by non-sensitized effector cells. The identity of the target cell varies, but it must possess surface IgG whose Fc portion is intact. The effector "killer" cell possesses Fc receptors. It may be a lymphocyte lacking conventional B- or T-cell markers, or a monocyte, macrophage, or polynuclear leukocyte, depending on the identity of the target cell. The reaction is complement-independent. ( NCI )]
