Aβ-binding with alcohol dehydrogenase drives Alzheimer's disease pathogenesis: A review.

Although Alzheimer's disease (AD) characterized with senile plaques and neurofibrillary tangles has been found for over 100 years, its molecular mechanisms are ambiguous. More worsely, the developed medicines targeting amyloid-beta (Aβ) and/or tau hyperphosphorylation did not approach the clinical expectations in patients with moderate or severe AD until now. This review unveils the role of a vicious cycle between Aβ-derived formaldehyde (FA) and FA-induced Aβ aggregation in the onset course of AD.
