SNCA triplication shapes neuronal extracellular vesicle biology and promotes microglial activation in patient-derived iPSC-based models of Parkinson's disease

Extracellular vesicles (EVs) are emerging as key mediators of intercellular communication and potential biomarkers in Parkinson's disease (PD), yet how disease-causing genetic alterations shape neuronal EV biology remains incompletely understood. Here, we used PD-patient iPSC-derived midbrain dopaminergic neurons (mDANs) harboring SNCA triplication (SNCA-4x), gene-corrected controls (SNCA-GC),…
