Purified human monocyte subsets as effector cells in antibody-dependent cellular cytotoxicity (ADCC). 1983

D L McCarley, and V O Shah, and R S Weiner

Human peripheral blood monocytes are heterogeneous with respect to their size and function. Two monocyte subsets were isolated by countercurrent centrifugal elutriation and were studied with respect to their ability to effect antibody-dependent cellular cytotoxicity (ADCC) and for the presence of Fc receptors on their surface. Both monocyte subsets display Fc surface receptors and are effectors of ADCC against sensitized human erythrocyte target cells. The demonstration of ADCC by monocyte effectors is dependent on their concentration in the incubation mixture. Dilution of monocytes below 10% by unlabeled and unsensitized erythrocytes or lymphocytes significantly suppresses ADCC, presumably by steric inhibition of effector and target contact.

D002498	Centrifugation	Process of using a rotating machine to generate centrifugal force to separate substances of different densities, remove moisture, or simulate gravitational effects. It employs a large motor-driven apparatus with a long arm, at the end of which human and animal subjects, biological specimens, or equipment can be revolved and rotated at various speeds to study gravitational effects.

D000920	Antibody-Dependent Cell Cytotoxicity	The phenomenon of antibody-mediated target cell destruction by non-sensitized effector cells. The identity of the target cell varies, but it must possess surface IMMUNOGLOBULIN G whose Fc portion is intact. The effector cell is a "killer" cell possessing 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.
