Seeds of destruction in Parkinson's disease: Spread of diseased proteins kills neurons

New research suggests that small "seed" amounts of diseased brain proteins can be taken up by healthy neurons and propagated within them to cause neurodegeneration. The research sheds light on the mechanisms associated with Parkinson's disease (PD) and provides a model for discovering early intervention therapeutics that can prevent or slow the devastating loss of neurons that underlies PD.
