Engineered neuronal exosomes mediate α-synuclein clearance to ameliorate Parkinson’s disease

Journal of Nanobiotechnology
Parkinson’s disease (PD) is the second most common neurodegenerative disorder after Alzheimer’s disease. A hallmark pathological feature of PD is the abnormal aggregation of α-synuclein (αSyn) into insoluble Lewy bodies.
