Autophagy plays an important role in Alzheimer's disease (AD). It has been reported that autophagic flux is altered in patients with AD, and application of the autophagy enhancer rapamycin may alleviate the cognitive impairment and amyloid-β (Aβ) neuropathology in transgenic animal model of AD. Since rapamycin is also an immune suppressor, there is a concern that long-term use of rapamycin may bring severe unwanted side effects. ⋯ We also documented that the cerebral amyloid plaque burden and Aβ42 levels in these mice are significantly reduced. Furthermore, we showed that CBZ significantly enhances the autophagic flux in the APP(swe)/PS1(deltaE9) mice which is unlikely via mTOR-dependent autophagy pathway. These data suggest that long-term CBZ treatment may have a protective effect in AD mouse model possibly through enhancing the autophagic flux.
