Researchers at Iowa State University have found an essential key to possibly cure Parkinson's disease and are looking for others.

Anumantha Kanthasamy, a distinguished professor of biomedical sciences and W. Eugene and Linda R. Lloyd Endowed Chair in Neurotoxicology at the ISU College of Veterinary Medicine, has been working to understand the complex mechanisms of the disease for more than a decade and thinks he has found hope for the cure.

Parkinson's disease sufferers lack a sufficient amount of a brain chemical called dopamine.

Kanthasamy's research shows that there is specific protein that is naturally present in human brains that -- for no known reason -- kills the brain cells that make dopamine.

The cells that are being killed are the ones that produce the needed dopamine.

"We have millions of cells in our brains," said Kanthasamy, "In Parkinson's, about 10,000 of these brain cells die; no one knows why."

Kanthasamy discovered that a novel protein -- known as protein kinase-C (specifically PKCδ) - is killing the dopamine-producing cells.
