Plasmodium falciparum picks (on) EPCR

摘要

Of all the outcomes of Plasmodium falciparum infection, the coma of cerebral malaria (CM) is particularly deadly. Malariologists have long wondered how some patients develop this organ-specific syndrome. Data from two recent publications support a novel mechanism of CM pathogenesis in which infected erythrocytes (lEs) express specific virulence proteins that mediate IE binding to the endothelial protein С receptor (EPCR). Malaria-associated depletion of EPCR, with subsequent impairment of the protein С system promotes a proin-flammatory, procoagulant state in brain microvessels.
