Project description:Certain strains of the intracellular endosymbiont Wolbachia can strongly inhibit or block the transmission of viruses such as dengue by Aedes mosquitoes, and the mechanisms responsible are still not well understood. Direct infusion and liquid chromatography FT-ICR mass spectrometry based lipidomicse DIMS and LCMS analyses were conducted using Aedes albopictus Aa23 cells that were infected with the wMel and wMelPop strains of Wolbachia compared to uninfected cells. Substantial shifts in the cellular lipid profile were apparent in the presence of Wolbachia. Most significantly, sphingolipids were depleted across all classes, and some reduction in diacylglyerol fatty acids and phosphatidylcholines was also observed. These lipid classes have previously been shown to be selectively enriched in DENV-infected mosquito cells, suggesting that Wolbachia may produce a cellular lipid environment that is antagonistic to viral replication. The data improve understanding of the intracellular interactions between Wolbachia and mosquitoes.

Project description:Cellular models have provided significant advances on molecular bases of bipartite interactions between either an arbovirus or a bacterial symbiont with a given arthropod vector. However, although an interference phenomenon was evidenced in tripartite interaction arbovirus-symbiont-mosquito vector very little is known regarding the mechanisms involved. Using large-scale proteome profiling, we characterized proteins differentially expressed in Aedes albopictus cells infected by the symbiotic bacterium Wolbachia and the Chikungunya virus (CHIKV). These proteins were mostly related to cellular processes involved in glycolysis process, protein metabolism, translation and amino acid metabolism. The presence of Wolbachia impacted significantly the protein profiles, including sequestration of proteins such as structural polyprotein and capsid viral proteins that may affect replication and assembly of CHIKV in cellulo. This study provides insights into the molecular pathways involved in the tripartite interaction mosquito-Wolbachia-virus and may help in defining targets for the better implementation of Wolbachia-based strategy for disease transmission control.
