Intracellular protein misfolding and aggregation are features of many late-onset neurodegenerative diseases (ND), called proteinopathies. These include Alzheimer’s disease, Parkinson’s disease, tauopathies and Huntington’s Disease. Currently, there are no effective strategies that slow or prevent the neurodegeneration resulting from these diseases in humans. These diseases are predicted to cause increasing economic and social burdens on society particularly as lifespan increases, hence the need for a better understanding of their biology and identification of therapeutic targets. Our work focuses on the roles of intracellular aggregate-prone proteins in the pathogenesis of ND and seeks to identify pathways which can enhance the clearance of these toxic proteins. We use zebrafish models of neurodegeneration to determine how different genetic modifiers affect disease severity and to identify novel therapeutic compounds which may be used as potential treatments for such diseases.
