CAP2 and Parkinson disease: Our analyses showed unaltered CAP2, SAP97, and ADAM10 protein levels in the SFG of PD and AD patients compared to control subjects (CAP2: CTRL vs. PD p = 0.6842; CTRL vs. AD p = 0.6842; SAP97: CTRL vs. PD p = 0.6842; CTRL vs. AD p = 0.6305; ADAM10: CTRL vs. PD p = 0.5288; CTRL vs. AD p = 0.5787; Mann–Whitney test) (Figure 8a–d).
