Dear Editor,This letter studies output consensus problem of heterogeneous linear multiagent systems over directed graphs. A novel adaptive dynamic event-triggered controller is presented based only on the feedback combination of the agent's own state and neighbors' output,which can achieve exponential output consensus through intermittent communication. The controller is obtained by solving two linear matrix equations, and Zeno behavior is excluded.

背景:神经营养因子是治疗脊髓损伤的新方法,调控自噬是其发挥作用的机制之一,但具体的信号通路尚不明确。目的:探讨神经营养因子3如何通过P75NTR/Trk C受体切换来调节少突胶质细胞的自噬以及促进脊髓损伤后神经功能恢复的作用,进一步明确具体的分子机制。方法:将24只SD大鼠随机分为3组:假手术组、脊髓损伤组和神经营养因子3组,通过大鼠后肢神经功能评分来评估神经营养因子3对脊髓损伤大鼠的治疗效果,采用Western blot检测各组大鼠脊髓组织中神经营养因子3、Olig1、MBP蛋白以及自噬标记蛋白LC3B的表达水平。在细胞实验中,将少突胶质细胞接种在培养皿中,分为糖氧剥夺组、糖氧剥夺+神经营养因子3组、糖氧剥夺+神经营养因子3+P75NTR质粒组、糖氧剥夺+神经营养因子3+Trk C质粒组、糖氧剥夺+3-甲基腺嘌呤(自噬抑制剂)组及糖氧剥夺+雷帕霉素(自噬激活剂)组。光学显微镜观察少突胶质细胞形态变化,TUNEL染色观察细胞凋亡现象,Western blot检测Trk C受体、P75NTR、LC3B表达及PI3K/AKT/m TOR和AMPK/m TOR信号途径的磷酸化状态。结果与结论:(1)动物实验显示,与假手术组相比,脊髓损伤后神经营养因子3的表达显著增加(P<0.05);与脊髓损伤组相比,外源性神经营养因子3治疗能够加快大鼠神经功能的恢复(P<0.05),并增加Olig1和MBP蛋白的表达(P<0.05);(2)细胞实验发现,3 h是损伤早期与中后期的分界点,与糖氧剥夺组相比,糖氧剥夺+神经营养因子3组少突胶质细胞能够更长时间地维持其形态,Trk C受体在早期表达水平较低而中后期显著上调(P<0.05),P75NTR则在早期上调而中后期下调(P<0.05),自噬水平呈现出先升高后降低的趋势(P<0.05);(3)通过对比糖氧剥夺+神经营养因子3组、糖氧剥夺+雷帕霉素组和糖氧剥夺+3-甲基腺嘌呤组的细胞形态和TUNEL染色结果,发现单独促进或抑制自噬对少突胶质细胞的存活均有不利影响,而类似神经营养因子3这样调节自噬的方法则能最大限度地维持细胞存活;(4)神经营养因子3在早期通过P75NTR/AMPK/m TOR信号通路促进自噬,而在后期通过Trk C/PI3K/AKT/m TOR信号通路抑制自噬。根据上述结果,得到如下结论,即神经营养因子3可以通过P75NTR/Trk C受体的切换能够双向调控少突胶质细胞的自噬,从而维持细胞存活,有助于脊髓损伤后大鼠的神经功能恢复。
