 Project objective

The impact of mosquito-borne diseases has expanded dramatically in the last few decades to become an emerging global health problem, with around 1 billion new infections and 1 million deaths each year. In Europe there are more than 20 countries with established populations of invasive Aedes mosquitoes. Aedes mosquitoes are the principle vectors responsible for transmitting high-risk pathogens such as ZIKA virus (ZIKV), dengue (DENV), yellow fever virus (YFV), chikungunya virus (CHKV) and Venezuelan equine encephalitic virus (VEEV). Despite our vulnerabilities to mosquito-borne diseases, virus replication dynamics is still poorly understood especially in the invertebrate vectors. No treatment against these viruses targeting essential viral proteins are currently available. Thus, the World Health Organisation (WHO) and its Vector Control Advisory Group has urged for insect vector control. Vector control is usually performed through insecticides; however, resistance can emerge in mosquitoes leading to persistence of the disease. Therefore, virologists are turning their interests toward host factors that play essential roles in infection as novel antiviral targets, since they can potentially exhibit broad-spectrum efficacy. In particular, scientists envision that genetically modified mosquitoes with disrupted genes required for infection can be re-inserted into natural habitats or through targeting these genes by RNAi in order to control viral spread. As all mosquito-borne viruses have RNA genome, cellular RNA-binding proteins (RBPs) emerge as ideal targets for antiviral therapies, as they are key players in cellular and viral RNA metabolism . Thus, we propose here to profile comprehensively the compendium of mosquito RBPs (RBPome) using RNA-interactome capture (RNA-IC). Furthermore, we will apply different cutting-edge methods to identify the role of mosquito RBPs during virus infection.
