Many neurodegenerative diseases, including Huntington's, Parkinson's, and Alzheimer's diseases, in human patients are both poorly understood and untreatable. In order to develop a deeper understanding of these disorders, a unifying theme in our lab is the study of mechanisms by which protein misfolding in the central nervous system leads to severe brain degeneration. Our research suggests that the manipulation of protein quality control systems, including the ubiquitin-proteasome system, the autophagic pathway, and heat-shock proteins may all exert dramatic effects on the development of pathology in these diseases. We use a variety of approaches, ranging from simple biochemical assays to complex transgenic organisms, in order to better understand the specific molecular and biochemical pathways that are involved in these diseases.
