Tadalafil impacts the mechanical properties of Plasmodium falciparum gametocyte-infected erythrocytes

Antibody responses to surface antigens of Plasmodium falciparum gametocyte‐infected erythrocytes and their relation to gametocytaemia

An essential element for continuing transmission of Plasmodium falciparum is the availability of mature gametocytes in human peripheral circulation for uptake by mosquitoes. Natural immune responses to circulating gametocytes may play a role in reducing transmission from humans to mosquitoes. Here, antibody recognition of the surface of mature intra-erythrocytic gametocytes produced either by a...

Plasmodium falciparum-infected erythrocytes: effects of arylaminobenzoates

Following invasion of the human erythrocyte by the malaria parasite, Plasmodiumfalciparum, there appear in the parasitized cell new, high-capacity permeation pathways that transport a diverse range of low-molecular-mass solutes. In this study a series of 16 arylaminobenzoates, analogues of the Clchannel blocker 5-nitro-2-(3-phenylpropylamino)benzoic acid (NPPB), were tested for their effects on...

Artemisone uptake in Plasmodium falciparum-infected erythrocytes.

Artemisone is one of the most promising artemisinin derivatives in clinical trials. Previous studies with radiolabeled artemisinin and dihydroartemisinin have measured uptake in Plasmodium falciparum-infected erythrocytes. Uptake is much greater in infected than in uninfected erythrocytes, but the relative contributions of transport, binding, and metabolism to this process still await definitio...

α-Thalassemia Impairs the Cytoadherence of Plasmodium falciparum-Infected Erythrocytes

BACKGROUND α-Thalassemia results from decreased production of α-globin chains that make up part of hemoglobin tetramers (Hb; α(2)β(2)) and affects up to 50% of individuals in some regions of sub-Saharan Africa. Heterozygous (-α/αα) and homozygous (-α/-α) genotypes are associated with reduced risk of severe Plasmodium falciparum malaria, but the mechanism of this protection remains obscure. We h...
