Researchers have found an essential key that could lead to new treatments and possibly a cure for Parkinson’s disease. They have identified the protein that kills dopamine-producing cells in the brain—and a way to disable it.
Parkinson’s disease sufferers lack a sufficient amount of dopamine. Anumantha Kanthasamy, a distinguished professor of biomedical sciences and W. Eugene and Linda R. Lloyd Endowed Chair in Neurotoxicology at Iowa State University, discovered that a novel protein—known as protein kinase-C—destroys dopamine-producing cells.
Kanthasamy and his research staff discovered a compound that neutralizes the cell-killing kinase-C and allows the dopamine-producing cells to survive and function.

Let's hope that this discovery does lead to a safe drug that does arrest or even cure Parkinson's.
May be good to check for updates in the future.
