Description

The malaria parasite Plasmodium falciparum establishes in the host erythrocyte plasma membrane new permeability pathways that mediate nutrient uptake into the infected cell. These pathways simultaneously allow Na + influx, causing [Na+] in the infected erythrocyte cytosol to increase to high levels. The intraerythrocytic parasite itself maintains a low cytosolic [Na+] via unknown mechanisms. Here we present evidence that the intraerythrocytic parasite actively extrudes Na + against an inward...[Show more]
