Our research focuses on dissecting molecular networks and mechanisms underlying human brain function and disease. Mutations in more than 400 genes are known to give rise to mental retardation, providing an exciting starting point into this problem. Some of these genes have been already shown to operate together to control specific aspects of nervous system development and function. We aim at systematically identifying such functional connections. In order to be able to investigate the large number of genes, we use the fruitfly Drosophila melanogaster as a model organism. In the fly, genes can be manipulated specifically in neurons with relative ease, and consequences for neuronal architecture, function and cognitive behaviour of the fly, such as learning and memory, can be studied and compared. Our long-term goal is to use the gained knowledge on mental retardation gene function and the fruitfly as a model to search for genetic and chemical modifiers of fly „mental retardation“ phenotypes. This research will identify novel candidate genes and potential medication for humans. Recent data indicate that some forms of mental retardation indeed result from reversible inabilities of the nervous system, raising serious hope that impaired cognition can be treated. Beyond the expected fundamental insights into molecular pathways wiring the brain, our research program also aims at significantly contributing to such developments. |
