Blood-brain barrier function in cerebral malaria in Malawian children

Abstract

Cerebral malaria (CM) is a serious complication of Plasmodium falciparum infection. Binding of parasitized erythrocytes to cerebral endothelium plays a key role in disease pathogenesis. Central nervous system signs and symptoms (coma, seizures, raised intracranial pressure) predominate in African children, whereas in adults, multiorgan system failure is more common. In this study we investigated whether changes in blood-brain barrier (BBB) structure and function are compatible with the signs and symptoms observed in Malawian children with CM. Immunohistochemistry on autopsy brain tissues from eight cases of CM showed activation of endothelial cells and macrophages, and disruption of endothel..
