HSPA5 and Parkinson disease: As expected, the results were consistent with the results of Baek et al. (2016), in which the level of GRP78 protein in cingulate gyrus was significantly higher in PDD and DLB patients compared to control subjects (∗∗∗∗P < 0.0001 for both PDD and DLB) and also to PD patients (#P < 0.0001 for both PDD and DLB) (Figure 1D,E).
