Recent advances in research throw more lights of its beneficial role towards Alzheimer's disease (AD), including promoting β-amyloid (Aβ) clearance, as well as inhibiting Aβ production in the triple-transgenic mouse model of Alzheimer's disease (3×Tg AD).

The TgF344-AD rat model of AD, bearing mutant human amyloid precursor protein (APPswe) and Presenilin 1 (PSEN1ΔE9) genes, has been described to manifest the full spectrum of AD pathology similar to human AD, i.e. progressive cerebral amyloidosis, tauopathy, neuronal loss and age-dependent cognitive decline.
