Single protein causes Parkinson's disease and multiple system atrophy

Several neurodegenerative disorders are caused by aggregates of a single protein known as alpha-synuclein. In collaboration with CNRS and the University of Antwerp, KU Leuven neurobiologists have discovered that the shape of these aggregates - 'cylinders' or 'ribbons' - determines whether a patient develops Parkinson's disease or Multiple System Atrophy, respectively.

Typical of neurodegenerative disorders is the disrupted communication between brain cells together with a loss of cells in specific brain regions. For some brain diseases this phenomenon is linked to a protein known as alpha-synuclein. The exact function of this protein remains unclear, but it may play a role in the communication between brain cells. However, in the case of specific diseases, including Parkinson's disease, Multiple System Atrophy (MSA), and dementia with Lewy bodies (DLB), this protein forms aggregates that cause neurodegeneration.
