Full textPlasmodium falciparum is the causative agent of human malaria. The increasing resistance of the malaria parasite to drugs has lead to the development of new trends. Proteases involved in essential metabolic pathways have been retained as potential targets to fight this parasite. Among these proteases, the aminopeptidase PfA-M1 seems to be a good candidate since it was shown that specific inhibitors of this enzyme can block parasite development. Encoded by a single copy gene in the P. Falciparum genome, PfA-M1 displays an optimal activity at pH 7. 4 and could play a role in haemoglobin degradation and/or red blood cells invasion. However its precise function in the parasite remains to be clarified, as recent studies on the localization of PfA-M1 have provided conflicting results. During this thesis, I focused my interest on the maturation process of PfA-M1 and on its traficking modalities to its final compartment of action. Such a project could provide a better understanding of the adaptative mechanisms acquired by this parasite during evolution. By immunofluorescence assays, using newly developed antibodies, PfA-M1 was localized in the cytoplasm of the parasite in vesicular structures. Biochemical analysis of three soluble forms of PfAM1 (p120, p96 and p68) resulted in evidence for their different subcellular localizations. The p120 form was found in the parasite and the parasitophorus vacuole, p96 was found in what seems to be vesicles in formation at the border of the parasite. The p68 form was found only in the parasite. These data suggest that after synthesis in the endoplasmic reticulum, p120 is sent to the parasitophorus vacuole and then processed into p96 form and finally returns to the parasite where it is found under the p68 form. To validate this model, we studied the effect of inhibitors disrupting haemoglobin uptake (mefloquine) or vesicular trafficking to the digestive vacuole (chloroquine). Our results showed that chloroquine favors the conversion of p120 into p96 while mefloquine causes an inverse effect. These two molecules also perturbe the targeting of PfA-M1 which localized in vesicles more intensively labelled in the parasite, in the presence of chloroquine and at the parasite's border, in the presence of mefloquine. Interestingly these vesicles are clearly distinct from those transporting haemoglobin to the digestive vacuole. To study the targeting signals of PfA-M1 by live imaging, we used plasmids allowing the expression of diverse domains of PfA-M1 genetically fused to the GFP. Expressed proteins present different locations which support the model that PfA-M1 uses the secretory pathway to reach its compartment of action. These results also suggest that the targeting signals of the enzyme are complex and probably localized in its N-terminal and C-terminal extremities. A theoretical study of the targeting signal conservation across the genus was undertaken by biocomputing analyses

Full textUsing Plasmodium berghei ANKA (PbA) infection in mice, one of the rare animal models of cerebral malaria (CM), this work aimed to study the interactions and mechanisms involved in mixed species infections. Our results showed a strong importance of species combination on the pathology induced by the infection. Thus, the development of CM was found to be unaltered for some parasite species combinations, whereas for P. Y. YoelII a complete abrogation of CM was observed. The migration to and sequestration of CD8+ T cells to the brain, previously demonstrated as playing a crucial role in the pathogenesis of CM, was found to be abolished in the mice co-infected with the protective species. Duplication of the experiments using a line of PbA that express a green fluorescent protein constitutively, established a species-specific suppression of PbA multiplication in the combinations where CM is abrogated. Sequential parasite inoculations revealed that protection from CM conferred by P. Y. YoelII persisted for extended periods after the resolution of the parasitaemia due to this protective species and suggested different protection mechanisms following the timing of inoculation of the two parasites. Finally, the study of the histological phenotype of mice and particularly their hepatic hematopoiesis, underlined the " yoelII " profile of animals co-infected with PbA and P. Y. YoelII. Taken together these results demonstrate the major role of mixed species infections in modulating malaria pathology and suggest the need for the study of Plasmodium interactions in humans

Full textThere are at least 300 million cases of malaria each year, resulting in more than a million deaths. Cerebral malaria is the most severe complication of malaria especially in young African children. Besides drug resistance, another challenge in the fight against malaria is the protective treatment of the host combined to the conventional antimalarial treatment. This opportunity came with the consideration of cerebral malaria residual case fatality rate of about 20%, despite a timely adequate antimalarial treatment. This work describes the available experimental model of cerebral malaria, the place of neuroprotective therapies in this disease and the efficacy of two neuroprotective drugs, recombinant erythropoietin and statins, during experimental cerebral malaria. Last, a proof-of-concept study documented the relevance of neuroprotection during human cerebral malaria in endemic area

Full textCerebral malaria (CM) is a parasitic neuroinflammatory disease due to infection with Plasmodium (P.) falciparum. The neurophysiopathological process is mainly linked to the sequestration of parasite infected erythrocytes in brain microvessels and to the activation of astrocytes and microglial cells, which creates a neurotoxic environment via the production of pro-inflammatory mediators and the recruitment to brain of pathological TCD8 lymphocytes. Recent findings on the gut-brain axis demonstrate the importance of the gut microbiota in modulating brain inflammation in different autoimmune neuropathological contexts such as Alzheimer or multiple sclerosis which share similarities with inflammatory mechanisms involved in CM. Here, we show that the dysbiosis of gut microbiota inhibits the development of CM. Indeed, CM susceptible mice with an altered gut microbiota due to treatment with a cocktail of antibiotics are protected from CM induced by infection with P. berghei ANKA. NGS analysis of the gut microbiota shown a change in the microbiome composition both in infected and treated-infected mice. This change correlated with the integrity of the brain blood and intestinal barriers. Indeed, akkermensia and parabacteroides, known for their anti-inflammatory properties, were among the most affected in CM infected resistant mice. Moreover, RTq-PCR analysis of proinflammatory cytokines and chemokines gene expression showed a reduction of the inflammatory response. In addition, flow cytometry analysis of astrocytes and microglia confirmed the decrease in their inflammatory phenotype during dysbiosis in infected mice similarly to mice resistant to CM. Altogether these results suggest that the gut microbiota composition can control brain inflammation by modulating the activity of glial cells during Malaria
