Early-onset impairment of the ubiquitin-proteasome system in dopaminergic neurons caused by α-synuclein

Chris McKinnon, et al, Acta Neuropathologica Communications, 2020.
In this study, McKinnon et al identify overexpression of α-synuclein leading to catalytic impairment of the 26S proteosome in defined regions of rat brains. Brain tissue was fixed following α-synuclein overexpression for immunofluorescence studies of dopaminergic neurons which were quantified by the HALO image analysis platform. Future research will focus on characterizing the relationship between proteasome impairment and neurodegeneration.
