✓ Peer-reviewed alzhub usefulness score 53 out of 100. Lewy body dementia

Topic: Brain proteins, microglia and lab models

Alpha-synuclein forms the major component of Lewy bodies and Lewy neurites, the defining neuropathological characteristics of Parkinson's disease and dementia with Lewy bodies. Here we show that alpha-synuclein is also the major component of the filamentous inclusions of multiple system atrophy which comprises several neurodegenerative diseases with a shared filamentous pathology in nerve cells and glial cells. These findings provide an unexpected link between multiple system atrophy and Lewy body disorders and establish that alpha-synucleinopathies constitute a major class of human neurodegenerative disorder.

Key findings

Why it matters

This study found that the protein alpha-synuclein is the main building block of the filamentous clumps seen in multiple system atrophy, as well as in Parkinson's disease and dementia with Lewy bodies. This links these conditions as related alpha-synuclein disorders, but it does not test any treatment or cure.
