Our research is focused on Parkinson’s disease and a group of related neurodegenerative disorders caused by PLA2G6 gene mutations. Accumulation of aggregated alpha-synuclein protein within neuronal inclusions called Lewy bodies and Lewy neurites is the hallmark pathological change in Parkinson’s disease. A central role for alpha-synuclein in pathogenesis is supported by the previous identification of dominantly-inherited alpha-synuclein gene mutations in rare familial forms of PD. PD typically causes progressive motor impairment but also can cause cognitive impairment. Disease progression is associated with progressive involvement of cortical and subcortical brain regions with pathological alpha-syn accumulation.
