RESEARCH HIGHLIGHT - Structures of alpha-synuclein filaments from multiple system atrophy

Parkinson’s disease (PD), dementia with Lewy bodies (DLB) and multiple system atrophy (MSA) are synucleinopathies. They are characterized by the presence of abundant filamentous inclusions of alpha-synuclein (α-syn) in nerve cells and glial cells, in the form of Lewy bodies and Papp-Lantos bodies. The relevance of inclusion formation was established when gene dosage and missense mutations in SNCA, the α-syn gene, were shown to cause inherited forms of PD and DLB, with abundant Lewy pathology. In diseases with Lewy pathology, α-syn inclusions are found mostly in nerve cells, whereas they predominate in glial cells in MSA. Several indirect lines of evidence have suggested that the inclusions in diseases with Lewy pathology and those in MSA are different conformers of assembled α-syn.
