This is the first study that examines dopamine transporter protein availability in vivo within the entire nigro-striatal pathway. The results suggest that at early stages of symptomatic PD a greater loss is observed at the level of the axonal terminals when compared with cell bodies and axons of dopaminergic neurons. The findings suggest a relative preservation of cell bodies in early PD, which might be relevant for novel disease-modifying strategies. © 2018 International Parkinson and Movement Disorder Society.
