title: Elucidation of the receptors in macrophage and Plasmodium yoelii interactions.
abstract: Binding of hyperimmune serum opsonized merozoites of Plasmodium Yoelii nigerensis to trypsinized macrophages suggested it to be mediated by FcII receptor. Receptor blocking inhibition with monoclonal antibody 2.4G2 directed against Fc receptor for IgG1/IgG2b provided evidence that Fc delta 2b on macrophage played an important role in the merozoite-macrophage interactions. In addition, a neuraminidase sensitive receptor was noted to mediate the binding of P. yeelii merozoites in the absence of serum. Binding inhibition studies with two monosaccharides, D-mannose and alpha-methyl mannoside, indicated the role of Mannose/Fucose receptor on macrophage in this interaction.
