ESR 1.1: Role of autophagy protein in the life cycle of mosquite-borne viruses



The candidate will be supervised by excellent scientists from the autophagy (Reggiori) and the mosquito-borne viruses (Smit) research groups. Autophagy is an intracellular degradative process, which is part of our innate immunity, and several microbes have developed mechanisms to subvert it. The groups has explored the relevance autophagy proteins in the replication of various viruses and the candidate will focus on arboviruses including Dengue, West Nile, Zika and Chikungunya viruses. Using our siRNA library and virus strains expressing GFP, the candidate will determine in an automated manner which autophagy genes are relevant for the studied infections. The role of the hits in infections will be then studied in molecular detail using cell biological, biochemical, ultrastructural and microbiological methods. We expect to identify and characterize new factors involved in the life cycle of these human pathogens, with the ultimate goal of providing novel therapeutic targets for the treatment of their infections.
