In PD brains, SNpc TH-immunoreactive somata and proximal neurites exhibited lower DJ-1-β-sub association than their VTA counterparts, whereas in control cases, no significant difference was observed between these two subcellular regions (Fig. 3, C and D—data the same as Fig. 3, A and B, rearranged to allow for this comparison). Here, TH is linked to Parkinson disease.
