May 24, 2022TWiN 30: Gut to brain spread of alpha-synuclein in Parkinson's disease
TWiN describes experiments demonstrating that gut injection of alpha-synuclein fibrils in mice converts endogenous alpha-synuclein to a pathologic form that spreads to the brain and leads to features of Parkinson's disease.
