　　The imbalance between β-amyloid(Aβ) generation and clearance plays a fundamental role in the pathogenesis of Alzheimer ’s disease(AD). The sporadic form of AD is characterized by an overall impairment in Aβ clearance. Immunotherapy targeting Aβ clearance is believed to be a promising approach and is under active clinical investigation. Autophagy is a conserved pathway for degrading abnormal protein aggregates and is crucial for Aβ clearance. We previously reported that oral vaccination with a re...
