Research reveals for the first time how Parkinson's develops
New Zealand-based researchers have provided what they claim is the first strong evidence on how Parkinson's disease spreads in the brain. Pathological proteins, known as Lewy bodies, spread from cell to cell through tunneling nanotubes that act as conduits. The study further stated that non-neuronal cells in the blood vessels called pericytes, also appear to harbour and spread Lewy bodies.
