CEREBRAL MALARIA-INDUCED APOPTOSIS AND BRAIN PATHOLOGY

这个子项目是众多研究子项目之一

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Malaria (P. falciparum) infects 200 to 300 million people globally and kills 2 million (mostly children) every year. 15% of fatal cases are due to cerebral malaria (CM) and other severe forms of malaria. A significant segment of CM patients die regardless of recommended treatment. A significant number of survivors develop neurological complications and cognition problems. The precise mechanisms responsible for CM induced brain damage and poor prognosis is unclear. The hypothesis is that Plasmodium apoptotic factor(s) (PAF) induce neuronal and microvascular endothelial cell apoptosis and that selectively blocking PAF mediated apoptosis will negate or significantly reduce apoptosis and CM-induced pathology. Our objective was to identify and characterize the role of PAF in CM-induced brain pathology using human brain endothelial (HBVEC), glial, and neuronal cell lines, as well as our established rodent CM model respectively. We utilized genomics, proteomics, immunological methods, imaging techniques, ultrastructural analysis, and targeted gene inactivation (RNA interference, RNAi) to pursue these goals.
