The insidious spread of an abnormal protein may be behind Parkinson’s disease, a study in mice suggests. A harmful version of the protein crawls through the brains of healthy mice, killing brain cells and damaging the animals’ balance and coordination, researchers report in the Nov. 16 Science.

If a similar process happens in humans, the results could eventually point to ways to stop Parkinson’s destruction in the brain. “I really think that this model will increase our ability to come up with Parkinson’s disease therapies,” says study coauthor Virginia Lee of the University of Pennsylvania Perelman School of Medicine in Philadelphia.
