STAT3信号转导系统介导了CNTF对大鼠尾壳核出血后的神经保护作用
EFFECT CILIARY NEUROTROPHIC FACTOR ON STAT3 LEVEL IN HIPPOCAMPUSOF RATS WITH PUTAMEN HEMORRHAGE
【摘要】 目的研究睫状神经生长因子(CNTF)在中枢神经元抗损伤中的作用及机制。方法对尾壳核出血大鼠进行CNTF治疗,观察海马信号转导和转录激活蛋白3(STAT3)含量及阳性神经元分布的变化。结果CNTF能显著增加尾壳核出血大鼠海马STAT3阳性神经元数量、海马STAT3含量。结论CNTF能通过促进STAT3的表达增强中枢神经元的抗损伤能力。
【Abstract】 ? Objective To investigate the role of ciliary neurotrophic factor (CNTF) in injury of central neuron. Methods Treat the rats of putamen hemorrhagewith CNTF and detect the signal transducer and activator of transcription 3 (STAT3) level , the number and distribution of STAT3 labled neuron in hippocampusof rats withputamen hemorrhage. Results CNTF significantly increased the STAT3 level and the number of STAT3 labled neuron in hippocampusof rats withputamen hemorrhage. Conclusion CNTF protects central neuron away from injury by facilitating the expression of STAT3. 〔
