Full textNonimmune civilians and military personnel traveling in malaria-endemic areas are at risk of malaria transmission and may become clinically ill during or after their travel. Approximately 25–30 million travelers from nontropical regions visit malaria-endemic countries annually, and about 30,000 cases of travel-associated clinical malaria occur each year. Each year, around 30. 000 French soldiers travelling in tropical areas are exposed to infectious diseases. Among them, malaria still represents an important threat as 12% of soldiers are infected by Plasmodium during their travel in spite of the respect of collective and individual protective measures against vector. The antimalarial chemoprophylaxis, mainly doxycycline (DOX) in the French Army, limits the number of clinical cases of malaria. However, since 2002, 3. 000 malaria cases have been reported in our forces. Around two of three were associated with a poor compliance especially after the return in France. The others cases might be explained by a decrease in the susceptibility of Plasmodium to DOX or a non optimal dosage. The aims of our work were to understand the mechanisms of action of DOX in P. Falciparum and to identify genetic determinants associated with a decrease susceptibility of P. Falciparum to DOX. In a first part, we studied the in vitro effects of DOX on P. Falciparum proteome at the asexual schizont stage by using of two differential proteomic technologies 2D DIGE and iTRAQ. Our findings suggest the apicoplast and the mitochondrion as targets for DOX. In a second study, the analysis of the distribution of DOX IC50s for 747 P. Falciparum African isolates by a Bayesian mixture modelling approach allowed us to find three different phenotypes of susceptibility to DOX. The cutoff of reduced susceptibility to DOX in vitro could be estimated to be 35μM. Then, we looked for genotypes associated with the three precedent phenotypes by sequencing eleven candidate genes and evaluating the copy numbers of two genes by quantitative real time PCR in 90 P. Falciparum African isolates. We have shown that pfmdt copy number > 1, pftetQ copy number > 1 and KYNNNN amino acid motif repetitions < 3 in TetQ protein were independently associated with decreased susceptibility to DOX

Full textThe Plasmodium falciparum sarco-endoplasmic reticulum ATPase Ca2+ pump (PfATP6) is a ten transmembrane protein involved in the regulation of the calcium homeostasis in the parasite. The importance of studying this protein relies on the fact that it has been hypothesized to be involved in the mechanism of action and resistance of artemisinins. Previous works, based on heterologous expression in Xenopus laevis oocytes and Saccharomyces cerevisiae, have shown contrasting results, generating many testable corollaries. Therefore, further work is needed to better understand the nature of interactions between artemisinins and SERCA-type transporters.In order to assess the essentiality of the gene in Plasmodium spp., a reverse genetics approach has been used. Knockout of the gene, in either P. falciparum and berghei, could not be achieved. Complementation for episomal rescue was found to be not possible. Tagging at the 3' end of PfATP6 and PbATP6 has been, also, attempted to study localization and expression of the protein in parasites. Manipulation of the gene at this position did not permit parasite survival. Our results, taken together, show that ATP6 is essential in Plasmodium spp..During our genetic studies, a stable and peculiar phenotype of Plasmodium falciparum 3D7 parasites has been noticed. The odd “monster” parasites contain an unusual swollen food vacuole throughout all stages of parasite development. Characterization of the unusual Plasmodium has been carried out, showing an increased sensitivity to chloroquine, but not to artemisinin or mefloquine. Taking into account the similarity of PfATP6 with the mammalian orthologue SERCA pump, new molecules, designed and synthesized to specifically target the mammalian protein, were tested on P. falciparum parasites. Four different classes of compounds (sHA 14-1, BHQ, chalcone and CPA analogues) showed to inhibit P. falciparum 3D7 and Dd2 growth in vitro at concentrations in the lower micromolar range. In addition, a novel class of molecules (thaperoxides), designed as an hybrid between artemisinin and thapsigargin, has been tested against 7G8 wild type and mutated L263E line. The latter carries a single nucleotide point mutation in PfATP6 that has been previously shown to be involved in artemisinin resistance. Considering the difficulty in manipulating the gene in the parasite and in order to better characterize PfATP6, a synthetic gene was optimized for heterologous expression in S. cerevisiae. This enabled successful complementation of a mutated yeast line (K616) lacking the endogenous P-type Ca2+ pumps, showing rescue of the yeast growth in presence of high concentration of free calcium. Different SERCA inhibitors, such as thapsigargin and cyclopiazonic acid, have been tested on K616 PfATP6 complemented yeast, in order to check for growth inhibition. All compounds showed to inhibit yeast growth selectively targeting PfATP6. In addition, the assay has been developed as a high throughput screening, in order to test new molecules for their activity. The method has proved to be a fast, highly reliable and reproducible tool for identification of new active compounds

Full textMalaria remains one of the main causes of infant mortality in the tropical world.The continuous emergence of parasite resistant to drug treatment is a serious threat to public health. Exploring new therapeutics targets based on depth knowledge on molecular mechanism of the parasite’s life is utmost needed in a paradigm of « red queen», which applies perfectly on the ability of the parasitic adaptation. The recent discovery of metacaspase of Plasmodium falciparum (PfMCA1) and the demonstration of its potential role in apoptosis, make it a therapeutic target against malaria. In order to increase knowledge about this protein, we planned, to determine the three-dimensional structure of PfMCA1, to confirm the different structures predicted in silico, and to look for new drug using molecular docking. However, this goal was not reached, since autoprocessing occurred during expression, and we failed to obtain the full-length protein. Then we studied the metacaspase of Plasmodium vivax (PvMCA1) in comparison with PfMCA1 and, we shown that histidine and cysteine residues in the dyad catalytic are well conserved. We have identified a second potential site in the catalytic domain of PvMCA1. We shown that residues in both putative sites are highly polymorphic in samples from Mauritania, Sudan and Oman. Mutations on these residues need to be deeply studied for their effects on the PvMCA1 function. This polymorphism found in catalytic residues of PvMCA1should be evaluated as new molecular marker of resistance
