Description
The abstract demonstrates VCP mutations promote alpha-synuclein aggregation leading to parkinsonism, but the mechanistic pathway is unexplained. Understanding this mechanism is critical since it could reveal novel therapeutic targets for both VCP-related disease and synucleinopathies more broadly.
