Amyloid beta (Aβ) is the main component of the amyloid plaques that accumulate in the brains of Alzheimer patients. Here, we reported the protective role of Formononetin (Form) against Aβ-induced neurotoxicity in HT22 cells. We found that Form significantly increased the viability of HT22 cells but decreased the cell apoptosis when challenging with AβThe inhibitory effects of Form were associated with PI3K/Akt signaling pathway as PI3K inhibitor (LY294002) or ERα specific inhibitor (MPP) blocked the effects. Form also accelerated the non-amyloidogenic process of amyloid precursor protein (APP) by enhancing α-secretase activity and sAPPα release. Altogether, our findings may provide a novel therapeutic target to treat AD sufferers.
