Immune genes 'key in Parkinson's disease'

The immune system may have a key role in the development of Parkinson's disease, say US researchers.
In a 20-year study of 4,000 people, half with Parkinson's disease, the team found an association between genes controlling immunity and the condition.
The results raise the possibility of new targets for drug development, Nature Genetics reports.

Mapping the human genome has certainly pushed research along..hopefully there is a cure to be found in the not too distant future.
