Antimicrobial protein implicated in Parkinson?s disease

An immune system protein that usually protects the body from pathogens is abnormally produced in the brain during Parkinson?s disease, scientists from Sanford Burnham Prebys report. The discovery, published in Free Radical Biology & Medicine, indicates that developing a drug that blocks this protein, called myeloperoxidase (MPO), may help people with Parkinson?s disease.
