Malaria Parasite clag3 Genes Determine Channel-Mediated Nutrient Uptake by Infected Red Blood Cells
Development of malaria parasites within vertebrate erythrocytes requires nutrient uptake at the host cell membrane. The plasmodial surface anion channel (PSAC) mediates this transport and is anExpand

A voltage-dependent channel involved in nutrient uptake by red blood cells infected with the malaria parasite
Growth of the malaria parasite in human red blood cells (RBCs) is accompanied by an increased uptake of many solutes including anions, sugars, purines, amino acids and organic cations. Although theExpand

Plasmodium falciparum likely encodes the principal anion channel on infected human erythrocytes.
Invasion by the human malaria parasite, Plasmodium falciparum, is associated with marked yet selective increases in red blood cell (RBC) membrane permeability. We previously identified an unusualExpand

An Epigenetic Antimalarial Resistance Mechanism Involving Parasite Genes Linked to Nutrient Uptake*
Background: Malaria parasites acquire antimalarial resistance through incompletely understood mechanisms. Results: Resistance to blasticidin S results from reversible silencing of parasite clag genesExpand

A nutrient-permeable channel on the intraerythrocytic malaria parasite
DURING its 48-hour cycle inside the red blood cell, the human malaria parasite, Plasmodium falciparum, increases its volume 25-fold and divides asexually. This rapid growth demands large amounts ofExpand

Solute Restriction Reveals an Essential Role for clag3-Associated Channels in Malaria Parasite Nutrient Acquisition
The plasmodial surface anion channel (PSAC) increases erythrocyte permeability to many solutes in malaria but has uncertain physiological significance. We used a PSAC inhibitor with differentExpand

A blasticidin S-resistant Plasmodium falciparum mutant with a defective plasmodial surface anion channel
Erythrocytes infected with malaria parasites exhibit marked increases in permeability to organic and inorganic solutes. The plasmodial surface anion channel (PSAC), an unusual voltage-dependent ionExpand

Malaria Parasites Are Rapidly Killed by Dantrolene Derivatives Specific for the Plasmodial Surface Anion Channel
Dantrolene was recently identified as a novel inhibitor of the plasmodial surface anion channel (PSAC), an unusual ion channel on Plasmodium falciparum-infected human red blood cells. BecauseExpand

Babesia and plasmodia increase host erythrocyte permeability through distinct mechanisms
Human erythrocytes infected with Plasmodium falciparum have markedly increased permeability to diverse solutes, many of which may be mediated by an unusual small conductance ion channel, theExpand

Malaria parasites tolerate a broad range of ionic environments and do not require host cation remodelling
Malaria parasites grow within erythrocytes, but are also free in host plasma between cycles of asexual replication. As a result, the parasite is exposed to fluctuating levels of Na+ and K+, ionsExpand
