Study of the immunopathological mechanisms involved in pregnancy-associated malaria


Every year at least 50 millions pregnant women are exposed to malaria infection. This high incidence is a result of the life threatening conditions of the mother and the developing fetus. Pregnancy-associated malaria (PAM) is characterized by the parasite sequestration in the maternal placenta with consequent maternal anemia, uterine growth retardation and decreased of the fetal viability. The high number of risk factors involved in PAM together with the inherent difficulties to study this disease in humans, are the main reasons why the molecular bases of this pathologic dysfunction are still poorly understood. This project aims to use a multiparametric approach in order to identify the cellular and molecular components of the innate and acquired immunity that contribute to the development of P AM, in mouse models. The knowledge of the innate immune response will bring an important contribution to the understanding of placental malaria. Moreover, makes it possible to address the development of new methodology studies, for PAM treatment. (AU)
