Abstract

Malaria is the most widespread parasitic disease, and despite the many efforts made to eradicate malaria, it accounts for more than half million deaths per year because the host-parasite interactions are not completely understood yet. Cerebral malaria (CM) is a severe neurological complication of infection with Plasmodium falciparum. Even after the appropriate antimalarial treatment, fatality rates range from 10 to 20% which highlights the importance of understanding the pathogenesis of this disease and of implementing new, rapidly acting interventions in combination with anti-plasmodium treatment. Although, cerebral malaria pathogenesis is complex and incompletely understood, observations from animal models and P. falciparum-infected humans support a hypothesis that it involves sequestration of parasitized erythrocytes and leukocytes by the brain microvasculature, and production of pro-inflammatory cytokines, such as IFN-³, TNF-, lymphotoxin-± e IL-12. However, the use of single knockout mutants for several pro-inflammatory cytokines have failed to show an obvious influence on cerebral malaria pathogenesis, suggesting that redundancy among those mediators. Previous results demonstrate that lipoxins, a class of anti-inflammatory lipid mediator derived from lipoxygenase-mediated metabolism of arachidonic acid, limit host damage during experimental cerebral malaria (ECM). In addition, animals treated with lipoxin showed prolonged survival and diminished brain inflammation. Thus, in the search for efficient therapies against CM and a better undertanding of the disease pathogenesis, the aim of this project is to elucidate the mechanisms involved in the lipoxin-induced CM protection and to determine its potential use, as adjuvant therapy, in association with antimalarials to treat severe malaria.
