Abstract: Parkinson’s disease (PD) and atypical Parkinsonian syndromes, such as multiple system atrophy (MSA) and Dementia with Lewy bodies, are neurodegenerative movement disorders characterized by the accumulation of alpha-synuclein (α-syn) aggregates. These α-syn aggregates propagate throughout the brain in a prion-like manner, where pathological α-syn recruits endogenous α-syn to form insoluble aggregates. Oligomeric forms representing intermediates on the way to insoluble aggregates result in the most pronounced neurotoxic effects. α-Syn aggregates can further assemble into Lewy bodies (LB) in PD and glial cytoplasmatic inclusions (GCI) in MSA, leading to neuronal dysfunction and degeneration.
