Abnormal Parkinson's Disease Protein Induces Degeneration in Healthy Nerve Cells, Penn Study Finds

Research from the Perelman School of Medicine at the University of Pennsylvania has found that small amounts of misshapened brain proteins can be taken up by healthy neurons and replicated within them to cause neurodegeneration. The research, published in Neuron, shows a way that Parkinson's disease (PD) can spread in the brain and provides a model for discovering therapeutics targeting PD...
