1、SICENCE 新闻发布 作者：赵雅宁 稿号： N201302030载脂蛋白载脂蛋白 E 拟肽能减少弥漫性脑损伤引起的神经细胞凋亡吗？拟肽能减少弥漫性脑损伤引起的神经细胞凋亡吗？大多数弥漫性脑损伤患者不适合手术，需寻找更有效的神经保护剂来治疗。载脂蛋白E在抑制慢性神 经变性过程中发挥重要作用，但其不能通过血脑屏障。而载脂蛋白E拟肽是较小的含有12个氨基酸的 肽段，可通过正常和受损的血脑屏障，目前对其是否有保护弥漫性脑损伤后神经功能的作用还不清 楚。河北联合大学附属医院李建民教授领导的团队进行了一项研究。发现尾静脉注射高低剂量的载 脂蛋白E拟肽（0.6mg/kg和1.2mg/kg）可改善弥漫性脑

Prof. Jianmin Li and team from the Affiliated Hospital of Hebei United University in China conducted a relevant study. These researchers found that apolipoprotein E-derived therapeutic peptide (0.6mg/kg and 1.2mg

Furthermore, apolipoprotein E mimetic peptide protected against brain injury by reducing oxidative stress, thereby suppressing the ERK1/2-Bax mitochondrial apoptotic pathway and decreasing neuro
