UCHL1 and Parkinson disease: Consistent with the previous findings,10,11,13,14,15,16,17,18,19,20,21 our analyses confirmed that phosphorylated αSynP was detectable with pS129-Syn (the antibody directed against phosphorylated α-synuclein) colocalized with PGP9.5 (an axonal marker), revealing the presence of phosphorylated αSynP in the skin nerve fibers of PD cadavers (Figure 1A and C) but not cadavers without PD by IHC (Figure 1B) and IF microscopy (Figure 1D-I).
