Inhibition of antibody-dependent cell-mediated cytolysis of tumor cells by Fc receptor of human cytomegalovirus

Abstract

The presence of HCMV-infected cells inhibits the killing of mouse tumor cells by adherent PEC in an antibody-dependent cell-mediated cytotoxicity (ADCC) test system. The effect of HCMV-infected cells on ADCC is mediated by the binding of IgG to the Fc receptors of infected cells.
