For long time Alzheimer's disease has been attributed to a cholinergic deficit. More recently, it has been considered dependent on the accumulation of the amyloid beta peptide (Aβ), which promotes neuronal loss and impairs neuronal function. Results/methodology: In the present study, using biophysical and biochemical experiments we tested the hypothesis that in addition to its role as a neurotransmitter, acetylcholine may exert its action as an anti-Alzheimer agent through a direct interaction with Aβ.
Our data provide evidence that acetylcholine favors the soluble peptide conformation and exerts a neuroprotective effect against the neuroinflammatory and toxic effects of Aβ. The present paper paves the way toward the development of new polyfunctional anti-Alzheimer therapeutics capable of intervening on both the cholinergic transmission and the Aβ aggregation.
长期以来,阿尔茨海默病一直被认为是由胆碱能缺陷引起的。最近,人们认为它依赖于β淀粉样肽(Aβ)的积累,Aβ会促进神经元丢失并损害神经元功能。结果/方法:在本研究中,我们通过生物物理和生化实验检验了以下假设:乙酰胆碱除了作为神经递质发挥作用外,还可能通过与Aβ的直接相互作用作为抗阿尔茨海默病药物发挥作用。
我们的数据提供了证据,表明乙酰胆碱有利于可溶性肽构象,并对Aβ的神经炎症和毒性作用发挥神经保护作用。本文为开发能够干预胆碱能传递和Aβ聚集的新型多功能抗阿尔茨海默病治疗方法铺平了道路。
