AMPK directly phosphorylates tau proteins at sites which affect microtubule association [157]
Decrease the activity of GSK3β and thereby decrease tau phosphorylation [104, 225]
Increase the activity of PP2A and facilitate the dephosphorylation of tau proteins [104]
Activate SIRT1 and facilitate tau clearance through ubiquitin-proteasomal system [114, 148]
Halt oxidative stress by reducing ROS production, activating antioxidant enzymes, enhancing the expression of antioxidants, and stimulating autophagic clearance [190, 205, 214, 219]
