Pearson correlation analysis showed a neutral correlation between AT8 and GFAP intensity in both AD (r = 0.032) and Ctr samples (r = 0.035), whereas there was a positive correlation between AT8 and S100B for both Ctr (r = 0.554) and AD (r = 0.338) (Figure 1C). Here, S100B is linked to Alzheimer disease.
