摘要: 本文应用免疫荧光、Western blot及Real-Time PCR等实验方法检测大蒜素对阿尔茨海默病模型小鼠脑内TNF-α表达的影响。结果发现,与对照组小鼠相比,模型组小鼠脑内TNF-α的阳性表达增加,提示在APP/PS1转基因小鼠脑组织中存在神经免疫炎症反应,而大蒜素处理组TNF-α表达明显低于模型组小鼠。基于此结果,说明大蒜素可以降低阿尔茨海默病模型小鼠脑内TNF-α的表达,提示大蒜素在阿尔茨海默病的抗炎临床治疗方面具有重要的理论意义。

Abstract: In this study,the effect of allicin on the expression of TNF-α in the brain of transgenic mice was investigated by immunofluorescence,Western blot and RealTime PCR assays.It was found that the expression of TNF-α in APP/PS1 transgenic mice increased compared with the wild-type mice.These results suggested that there were inflammation reaction in APP/PS1 transgenic mouse brain,but the expression of TNF-α in allicin treatment group was significantly lower than that in APP/PS1 transgenic mice.These results prompt that there were inflammation reaction in APP/PS1 transgenic mouse brain.TNFα expression in allicin treatment group was lower than that in APP/PS1 transgenic mice.

Key words: allicin, Alzheimer&rsquo, s disease, APP/PS1 transgenic mice, TNF-&alpha
