Further Information

Research focus: Protein aggregation is a hallmark of many neurodegenerative diseases, but the mechanisms of aggregate toxicity remain incompletely understood. Moreover, it is largely unknown how the demise of the vulnerable neuronal cell types affects the functionality of neural circuits. We address these questions in particular in models of Huntington’s disease, a devastating hereditary movement disorder caused by a CAG repeat expansion in the Huntingtin gene. We work with primary neuronal cultures and mouse disease models, and use cell biological, biochemical and histological methods, as well as behavioural tests and in vivo two-photon imaging. Our goal is to identify molecular pathways and neural circuit impairments that play a role in disease progression and could provide targets for new therapeutic approaches.

Key words: neurodegeneration, protein aggregation, Huntington’s disease, neural circuits, mouse genetics, cell biology, histology, mouse behavior, in vivo imaging.
