“We also found that BBR significantly decreased the levels of C-terminal fragments of APP and the hyperphosphorylation of APP and tau via the Akt/glycogen synthase kinase 3 signaling pathway in N2a mouse neuroblastoma cells stably expressing human Swedish mutant APP695 (N2a-SwedAPP).”
“According to our study, berberine did not only significantly improve 3×Tg AD mice's spatial learning capacity and memory retentions, but also attenuated the hyperphosphorylation of tau.”
“Moreover, berberine reduced the level of tau through an autophagy-based route.”
“Thus, our results suggest that berberine could mitigate cognitive decline by simultaneously targeting the hyperphosphorylation of tau and the autophagic clearance of tau in AD mice.”
“ Berberine significantly attenuated memory impairment, axonopathy, and tau hyperphosphorylation, and also restored PI3K/Akt/GSK3β signaling pathway in T2D rats.”
