Alzheimer's disease (AD) is a neurodegenerative disease and our current treatment approach can only delay its course rather than cure it completely. Flavones from L. have been reported to promote synaptic plasticity and indirectly affect the expression of cholinergic neurotransmitters in a rat model of Alzheimer's disease.
The aim of the study is to explore the effect of L. in APP/PS1 Alzheimer model mice.
APP/PS1 AD mice were used as the research subjects, and the mice were divided into a model group, donepezil group, VTF low-dose group, VTF medium-dose group, and VTF high-dose group. C57BL/6 mice served as a control group. The autophagosomes were observed by a transmission electron microscope, and the expressions of LC3I, LC3IIand Beclin-1 were determined by Western blotting. The results of qRT-PCR are consistent with Western blotting.
VTF can exert a positive regulatory effect on AD mice by inhibiting autophagy.
Our study supports that intragastrically administration of VTF is effective and operable in Alzheimer's disease mice, and that inhibition of excessive autophagy may be one of the potential reasons why VTF exerts a therapeutic effect on AD.
阿尔茨海默病(AD)是一种神经退行性疾病,我们目前的治疗方法只能延缓其病程,而不能完全治愈。据报道,来自[植物名称未给出]的黄酮类化合物可促进突触可塑性,并间接影响阿尔茨海默病大鼠模型中胆碱能神经递质的表达。
本研究旨在探讨[植物名称未给出]对APP/PS1阿尔茨海默病模型小鼠的影响。
以APP/PS1 AD小鼠为研究对象,将小鼠分为模型组、多奈哌齐组、VTF低剂量组、VTF中剂量组和VTF高剂量组。以C57BL/6小鼠作为对照组。通过透射电子显微镜观察自噬体,并通过蛋白质免疫印迹法检测LC3I、LC3II和Beclin-1的表达。qRT-PCR结果与蛋白质免疫印迹法一致。
VTF可通过抑制自噬对AD小鼠发挥正向调节作用。
我们的研究支持胃内给予VTF对阿尔茨海默病小鼠有效且可行,并且抑制过度自噬可能是VTF对AD发挥治疗作用的潜在原因之一。
