A fundamental challenge in modern science is to understand how the brain functions in health and disease. Despite growing incidences of neurodegenerative diseases, we still lack basic understanding of mechanisms leading to chronic neurodegeneration in the brain. Traumatic brain injury (TBI) –which can occur due to sports, traffic accidents, falls and violence-, is a major cause of death and disability in children and young adults especially in developed countries. People surviving after TBI often suffer from long term consequences due to chronic neurodegeneration –trigged by initial trauma–, which can lead to neuropsychiatric problems as well as early onset of dementia including Alzheimer’s disease. We are interested in understanding cellular and molecular mechanisms leading to chronic neurodegeneration after traumatic brain injury using novel approaches. To this end, we utilize recently developed state-of-the-art techniques including 3D imaging of entire cleared brains –developed by us-, rabies virus tracing of neuronal networks, optogenetics and in vivo 2-photon imaging. Our overall goal is to determine molecular players that can be targeted (genetically or pharmacologically) to develop novel ways to halt chronic neurodegeneration after TBI.
