Drosophila as a lipotoxicity model organism--more than a promise?

Looking back over the century long research career of the fruit fly, Drosophila melanogaster has frequently been in the scientific spotlight with respect to fundamental discoveries in biology. The last decade witnessed the increasing importance of the fly as a human disease model but studies on energy homeostasis and lipometabolism remain in their infancy. This perspective, addressing readers largely unfamiliar with the Drosophila model system, aims to highlight the starting points for which the fly could be employed to gain a deeper understanding of lipotoxicity and possibly contribute to strategies for the identification of novel drug targets relevant to type 2 diabetes mellitus and the metabolic syndrome.
