Glutathione export from uninfected human erythrocytes was compared with that from cells infected with the malaria parasite Plasmodium falciparum using two separate methods that distinguish between oxidized (GSSG) and reduced (GSH) glutathione.

Glutathione efflux from uninfected erythrocytes under physiological conditions occurred predominantly as GSH. On exposure of the...[Show more]
