Possible Parkinson's link to immune system

Why do some people develop Parkinson's? Researchers say a new report strengthens the idea that the immune system plays a key role.

In a 20-year study of 4,000 people, U.S. researchers found an association between genes controlling immunity and the condition. These genes are key for the immune system to differentiate between foreign invaders and the body's own tissues.

According to the report in the journal Nature Genetics, the discovery raises the possibility of new targets for drug development.
