Hemoglobin metabolism in the malaria parasite Plasmodium falciparum.
Hemoglobin degradation in intraerythrocytic malaria parasites is a vast process that occurs in an acidic digestive vacuole. Proteases that participate in this catabolic pathway have been defined.Expand
Human immunodeficiency virus type 1 long-term non-progressors: the viral, genetic and immunological basis for disease non-progression.
A small subset of human immunodeficiency virus type 1 (HIV-1)-infected, therapy-naive individuals--referred to as long-term non-progressors (LTNPs)--maintain a favourable course of infection, oftenExpand
The role of neutral lipid nanospheres in Plasmodium falciparum haem crystallization.
The intraerythrocytic malaria parasite constructs an intracellular haem crystal, called haemozoin, within an acidic digestive vacuole where haemoglobin is degraded. Haem crystallization is the targetExpand
Copper pathways in Plasmodium falciparum infected erythrocytes indicate an efflux role for the copper P-ATPase.
Copper, like iron, is a transition metal that can generate oxygen radicals by the Fenton reaction. The Plasmodium parasite invades an erythrocyte host cell containing 20 microM copper, of which 70%Expand
Plasmodium falciparum-infected erythrocytes induce NF-kappaB regulated inflammatory pathways in human cerebral endothelium.
Cerebral malaria is a severe multifactorial condition associated with the interaction of high numbers of infected erythrocytes to human brain endothelium without invasion into the brain. The resultExpand
New uses for old drugs
It takes too long and costs too much to bring new drugs to market. So let's beef up efforts to screen existing drugs for new uses, argue Curtis R. Chong and David J. Sullivan Jr. Drug rediscovery isExpand
Plasmodium Hemozoin Formation Mediated by Histidine-Rich Proteins
The digestive vacuole of Plasmodium falciparum is the site of hemoglobin degradation, heme polymerization into crystalline hemozoin, and antimalarial drug accumulation. Antibodies identifiedExpand
A clinical drug library screen identifies astemizole as an antimalarial agent
The high cost and protracted time line of new drug discovery are major roadblocks to creating therapies for neglected diseases. To accelerate drug discovery we created a library of 2,687 existingExpand
Plasmodium falciparum-Infected Erythrocytes Increase Intercellular Adhesion Molecule 1 Expression on Brain Endothelium through NF-κB
ABSTRACT Sequestration of Plasmodium falciparum-infected erythrocytes (Pf-IRBC) in postcapillary brain endothelium is a hallmark of cerebral malaria (CM) pathogenesis. There is a correlation betweenExpand
Purified Malaria Pigment (Hemozoin) Enhances Dendritic Cell Maturation and Modulates the Isotype of Antibodies Induced by a DNA Vaccine
ABSTRACT Hemozoin (malaria pigment) has been implicated in the modulation of immune responses during malaria infection. This study was designed to evaluate the effect of purified hemozoin on the inExpand
