Research/Clinical Interest
Title
Pathogenesis of Huntington's Disease
Description
My work is focused broadly on uncovering the mechanisms that contribute to Huntington’s Disease (HD) pathogenesis. Huntington’s Disease is an autosomal dominant neurodegenerative disorder characterized by motor, psychiatric and cognitive deficits. The disease is caused by a repeat expansion in the ubiquitously expressed huntingtin protein. Although the protein is widely expressed, only a subset of neurons is affected in disease. My current work is focused on understanding the overall contribution of glial cells (which constitute about 50% of cells in the brain) to HD pathology. This includes understanding the normal function of the huntingtin protein in glial cells and determining how the mutant protein in glial cells contributes to neuronal dysfunction in HD. We use conditional mouse genetic models to dissect cell type contribution to disease. We employ BAC transgenesis technology to generate animal models that are then characterized using molecular, cellular, biochemical and neuropathological techniques.
