A cellular mechanism that involves the recycling of cell substances and protects cells against degeneration may, when it is disrupted, play a role in Parkinson disease, according to researchers at Emory University School of Medicine in Atlanta.
The presence of aggregates of a protein implicated in Parkinson disease, alpha-synuclein, in lesions called Lewy bodies in patients with the disorder has suggested that there is a problem with protein recycling and waste disposal in Parkinson disease. But until now a mechanism underlying this disruption hasn't been clear.
