Research Theme

Our research program is focused on the role of dopamine in behaviour control and neurodegenerative mechanisms in the fruit fly Drosophila melanogaster. Our approach combines Drosophila genetics, molecular biology, brain imaging and behavioral assays. We recently generated and characterized brain dopamine-deficient mutants and developed new models to study pathogenic mechanisms related to genetic and environmental factors of Parkinson disease. Our current goal is to identify genes and brain neuronal networks required to maintain locomotor activity and stress resistance during lifespan in healthy flies and Parkinson models. On-going studies address the role of specific mitochondrial and lysosomal proteins as well as the inluence of circadian genes in neuroprotection.
