Nurr1 protects against neurotoxins that spur inflammation and Parkinson's disease

A new study in the April 3rd issue of the journal Cell, a Cell Press publication, helps to explain why people who carry mutations in a gene known as Nurr1 develop a rare, inherited form of Parkinson’s disease, the most prevalent movement disorder in people over the age of 65.

They have found evidence that the gene normally acts to suppress an inflammatory response and, in turn, the production of neurotoxins in the brain. Those neurotoxins can otherwise spawn the damage to dopaminergic neurons that is characteristic of Parkinson’s disease. The findings not only offer new insight into the causes of the disease, but also may point to new avenues for therapy, according to the researchers.
