The cause of neuronal death in Parkinson’s disease is still unknown, but a new study proposes that neurons may be mistaken for foreign invaders and killed by the person’s own immune system, similar to the way autoimmune diseases like type I diabetes, celiac disease, and multiple sclerosis attack the body’s cells. The study was published April 16, 2014, in Nature Communications.
“This is a new, and likely controversial, idea in Parkinson’s disease; but if true, it could lead to new ways to prevent neuronal death in Parkinson’s that resemble treatments for autoimmune diseases,” said the study’s senior author, David Sulzer, PhD, professor of neurobiology in the departments of psychiatry, neurology, and pharmacology at Columbia University College of Physicians & Surgeons.
The new hypothesis about Parkinson’s emerges from other findings in the study that overturn a deep-seated assumption about neurons and the immune system.
