Rejuv Res:广州中医药大学发现黄连素可以治疗糖尿病有关的认知能力下降

2017-11-01 佚名 medicalxpress

研究自然、植物源化合物黄连素的作用机制的研究人员,已经将其抗炎活性和调节压力反应蛋白水平的能力联系在一起,包括长寿因子和黄连素对记忆丧失和衰老的糖尿病小鼠模型学习障碍的积极影响。除了改善糖尿病脑病和中枢神经系统退化,黄连素还与糖尿病小鼠的脂质代谢和空腹血糖降低有关。

研究自然、植物源化合物黄连素的作用机制的研究人员,已经将其抗炎活性和调节压力反应蛋白水平的能力联系在一起,包括长寿因子和黄连素对记忆丧失和衰老的糖尿病小鼠模型学习障碍的积极影响。除了改善糖尿病脑病和中枢神经系统退化,黄连素还与糖尿病小鼠的脂质代谢和空腹血糖降低有关。

这篇题为《黄连素通过SIRT1/ER应激通路改善糖尿病脑病》的文章是由张世杰和陈云波领导的广州中医药大学的一组研究人员撰写的。研究人员集中研究了黄连素对内质网(ER)应激蛋白介导信号通路的影响。糖尿病会引起ER压力,并与脑神经突触的高血糖诱导功能障碍和认知障碍有关。根据本研究的结果,作者得出结论,黄连素可以通过干预SIRT1/ER应激途径来预防糖尿病性脑病的影响。

虽然糖尿病名义上是由于多余的脂肪和糖原储存,但它是年龄相关的不同组织的衰退相互交织作用而成,大脑无法逃避它的影响,”总编AubreyD.N.J.deGrey说,“既然我们想继续发展有效的治疗手段,我们就必须找出最有效的关键一点。而在这个试验中证实了黄连素非常有希望成为治疗糖尿病性脑病的关键”
