Study finds way to prevent protein clumping characteristic of Parkinson's disease

Researchers at the University of Pennsylvania School of Medicine have identified a protein from a most unlikely source -- baker's yeast -- that might protect against Parkinson's disease. More than a million Americans suffer from Parkinson's disease, and no treatments are available that fundamentally alter the course of the condition. By introducing the yeast protein Hsp104 into animal models of Parkinson's disease, researchers prevented protein clumping that leads to nerve cell death characteristic of the disorder.
