Furthermore, a correlation analysis between miR‐32533 and AD diagnostic markers showed that miR‐32533 expression in the plasma of AD patients was correlated with the ratio of Aβ1‐42/Aβ1‐40 (Figure 1Q and p = 0.02), but not significantly correlated with the level of tau phosphorylation at threonine 217 (p‐Tau217) (Figure 1R and p = 0.08). Here, MAPT is linked to Alzheimer disease.
