In vitro inhibition of Plasmodium falciparum merozoite invasion by human plasma fibronectin
Published online by Cambridge University Press: 06 April 2009
Extract
Human fibronectin isolated from citrated blood was tested for its ability to bind to Plasmodium falciparum by an indirect immunofluorescent assay using rabbit antiserum to human fibronectin. A positive reaction was observed on merozoites inside schizont-infected erythrocytes. The binding was not observed on non-parasitized red blood cells. The effect of human fibronectin on P.falciparum growth was further studied using an in vitro inhibition assay; 50% inhibition of parasite multiplication was obtained with approximately 100 μg/ml of human fibronectin. Slight inhibition was observed below 10 μg/ml. The significance of this finding is discussed.
