  • Title: Nucleoside permeation in mouse erythrocytes infected with Plasmodium yoelii.
    Author: Gati WP, Stoyke AF, Gero AM, Paterson AR.
    Journal: Biochem Biophys Res Commun; 1987 Jun 30; 145(3):1134-41. PubMed ID: 3606597.
    Abstract:
    In normal mouse erythrocytes, nucleoside permeation was almost completely blocked in the presence of binding site-saturating concentrations of nitrobenzylthioinosine, whereas permeation in erythrocytes infected with the malarial parasite, Plasmodium yoelii, was substantial under these conditions, suggesting the presence of a permeation mechanism of low sensitivity to nitrobenzylthioinosine in the infected cells. Binding sites for nitrobenzylthioinosine were more numerous on infected erythrocytes than on uninfected cells. When mice infected with P. yoelii were treated with combinations of tubercidin and nitrobenzylthioinosine 5'-monophosphate, progression of parasitemia was delayed and survival times were increased.
