Analyse anthropobiologique de la susceptibilité au paludisme chez l'homme

Abstract : Malaria remains the parasitic disease with the highest rates of morbidity and mortality and its socio-economic impact is an obstacle to development.There has been a coevolution between human host, the vector and Plasmodium with sometimes specific adaptations of resistance, leading today into resistance of Plasmodium to antimalarial products and the difficulties to develop an effective vaccine. The exploration of new areas of research is therefore relevant for the understanding of some adaptations that may have implications in the susceptibility to malaria.Differences in susceptibility to malaria have been described in symmetric Fulani and Dogon in Mali. Most of the studies carried out to understand this difference in susceptibility have focused on immunity. In this work, we have implemented a more global and innovative approach, studying the inteplay between the environment, the immune system and susceptibility to malaria. We investigated the relationship between diet, metabolism and immunity, which is an example of interaction between environment and biology.In our study, we described differences between Fulani and Dogons of Mali in terms of blood levels of AGE and sRAGE, as well as in expression and polymorphism of the RAGE receptor. This could have implications for the immune system and therefore for susceptibility to malaria. These results provide important baseline data for supporting a new malaria research approach by combining diet, metabolism, and gut microbiota which is also currently of great interest in malaria
