摘要

目的:观察谷氨酸诱导海马神经元兴奋毒性损伤中神经营养因子受体p75（p75 neurotrophin receptor

p75NTR）表达水平的变化。方法:建立谷氨酸诱导的新生大鼠海马神经元兴奋毒性损伤模型

RT-PCR和Western blot方法检测p75NTR在mRNA和蛋白质水平的表达变化。结果:谷氨酸刺激后

p75NTR在mRNA（P<0.01）和蛋白质（P<0.05）水平的表达较对照组明显增高;N-甲基-D-门冬氨酸受体（N-methyl-D-aspartate receptor

NMDAR）的特异性拮抗剂MK-801可明显减弱p75NTR在mRNA和蛋白质水平的表达上调（P<0.05）。结论:p75NTR的活化与谷氨酸兴奋毒性神经损伤过程密切相关。

Abstract

Objective:To observe the change in expression level ofp75NTR(p75 neurotrophin receptor)in cultured hippocampal neurons during glutamate-induced excitotoxicity.Methods:Excitotoxicity was induced by glutamate in rat cultured hippocampal neurons; RT-PCR and western blot were used to detect the change in expression level of p75NTR.Results:After glutamate exposure

p75NTR mRNA(P<0.01)and protein(P<0.05)levels had evaluated markedly compared with control group;MK-801

a specific antagonist of N-methyl-D-aspartate recepto(rNMDAR)could decrease p75NTR mRNA and protein levels dramatically compared with glutamate group (P<0.05).Conclusion:p75NTR plays an important role in neuronal damage during glutamate-induced excitotoxicity.
