Further evidence autoimmunity plays a role in Parkinson’s disease

This shows a neuron and t cellT cells that react to alpha-synuclein are most abundant in the early stages of Parkinson’s disease but tend to disappear as the disease progresses. Signs of autoimmunity can appear in Parkinson’s patients up to ten years before a diagnosis of the neurodegenerative disease. The detection of T cell response could be an early biomarker for Parkinson’s, long before the physical symptoms begin to manifest.
