Abstract:
The massive accumulation of β-amyloid （Aβ） in the brain is believed to be the first pathological mechanism of Alzheimer's disease （AD）， and the accumulation is mainly resulted from the overproduction and dysfunction in the clearance. Extensive and in-depth research has been carried out on AD. In addition to the drugs which are commonly used in clinical settings to improve cognitive function， Aβ monoclonal antibody aducanumab （Aduhelm） has been successfully marketed in the US， which may delay the progress of AD. Thus， it is a potential method for the treatment of AD to target Aβ， but it is expensive， with many adverse reactions and contraindications， which hinders the clinical promotion. Traditional Chinese medicine， featuring multiple components， multiple targets， multiple pathways， and high safety， can regulate the level of Aβ deposition in the brain， alleviate neurotoxicity， and prevent and treat AD by inhibiting the production and aggregation of Aβ and promoting the clearance in the brain. Berberine， gallic acid， osthole， scutellaria barbata flavonoids， Huannao Yicong decoction and Ditantang can promote α-secretase and inhibit the activity and expression of β- and γ-secretase， thus reducing production of Aβ. Baicalein， aloe-emodin， gallic acid， and curcumin can suppress the aggregation of Aβ， promote its depolymerization， and reduce the toxic effect of Aβ on nerve cells by interacting with the hydrophobic structure of Aβ and the H bond， salt bridge， and β-sheet that mediate the aggregation of Aβ. Curcumin and resveratrol can promote the expression of triggering receptor 2 in bone marrow cells of microglia and the migration and phagocytosis of Aβ in microglia. Bilobalide， Kaixinsan and curcumin can up-regulate the expression of encephalin-degrading enzyme and insulin degrading enzyme to promote Aβ degradation， and geniposide， dihydrotanshinone， dihydroartemisinin， and curcumin can degrade Aβ in cells by activating normal autophagy or inhibiting abnormal autophagy. Cycloastragenol， Danggui Shaoyaosan， Yizhi Fangdai formula and Linggui Zhugan decoction can promote the outflow of Aβ and inhibit the inflow of Aβ by improving the integrity and permeability of the blood-brain barrier （BBB）. Yizhi Fangdai formula and Xueshuantong can promote the polarization of aquaporin 4（AQP4）， allow Aβ to be cleared through the lymphatic system， and reduce the aggregation of Aβ in the brain， thereby relieving or preventing nerve cell damage and improving cognitive function. The above summary aims to provide more sufficient evidence and ideas for the clinical treatment of AD with traditional Chinese medicine.
