title: Selective action of D-penicillamine on guinea pig peritoneal macrophage Fc gamma receptors for homologous, monomeric IgG1.
abstract: Guinea pig oil-induced peritoneal exudates were pretreated with D-penicillamine. The binding of homologous, monomeric IgG2 and IgG1 to normal and pretreated exudates was examined. Whereas the 7S IgG2-IgG2 Fc gamma receptor interaction remains unaffected by the pretreatment, the binding of IgG1 to the IgG Fc gamma receptor population was affected. The significance of the selective effect of D-penicillamine is discussed.
