ABSTRACT Cerebral malaria (CM) is known to be the most severe complication of Plasmodium falciparum infection. Despite effective anti-parasitic treatment, it remains a major cause of morbidity and mortality in infected children. Sequestration of infected red blood cells in the brain microvasculature, occlusion of blood flow, activation and subsequent damage of the endothelium are hallmarks of the pathogenesis of CM. This study sought to quantify and compare time course levels of cEPC and othe...
