小胶质细胞对大脑认知障碍的研究进展

open access: yesZhongguo shiyan zhenduanxue, 2023
小胶质细胞是由血液中的单核细胞演化而来,是中枢神经系统内特殊的免疫细胞,也是神经炎症的主要调节因素之一,在生理学上对宿主防御和组织修复至关重要。小胶质细胞在大脑老化的过程中起到重要作用,本文就此内容展开综述。1 大脑认知功能老化的机制大脑认知的变化是衰老的正常过程。大脑的概念推理、

血管内注射可溶性 Aβ1-40 对鼠脑神经胶质细胞的影响

open access: yesZhongshan Daxue xuebao. Yixue kexue ban, 2004
目的探讨血液内较高浓度的可溶性Aβ1-40在阿尔茨海默病发病中的作用。方法15只大鼠随机分为3组,实验组、生理盐水组和空白对照组,每组5只,通过大鼠颈部血管插管至心脏并留置的方法,向实验组大鼠血液中每日2次注射10μg的可溶性Aβ1-40,对照组注射同样剂量的生理盐水,而空白对照组不作任何处理。连续14日后,采用免疫组化方法观察各组大鼠大脑皮质及海马的星形胶质细胞、小胶质细胞。【结果】与生理盐水组和空白对照组相比,实验组注射Aβ1-40以后,皮层 ...

The effect and mechanism of 3–(6–phenylhexanoyl)oxazolidin–2–one in the central inflammation [PDF]

open access: yes, 2017
摘要 研究背景:近年来,NAAA作为抗炎镇痛的靶标,在炎症,疼痛,癌症等各种疾病进程中的作用已有越来越多的探究和验证。通过抑制NAAA的作用,可以提高组织中PEA和OEA等脂肪酰基乙醇胺的含量,达到抗炎、镇痛以及神经保护等作用。现有的NAAA抑制剂大多是局部用药,且活性较差,半衰期短,不利于口服和整体动物实验,使用受到很大的限制,新型的NAAA抑制剂的研究已成为当务之急。 目的:本课题组已合成结构稳定,活性强,毒副作用小的NAAA抑制剂F96,本研究通过一系列实验确定F96在脑部的抗炎作用 ...

胶质瘤源性Exosome的研究进展

open access: yesZhongguo shiyan zhenduanxue, 2012
脑胶质瘤起源于脑部神经胶质细胞,是最常见的颅内肿瘤,有逐年增长的趋势。胶质母细胞瘤患者的平均存活期小于15个月[1]。数十年来,尽管手术治疗、放射治疗以及生物化学治疗在临床上普及应用,但是患者的生存期未见明显延长[2]。1987年,Johnstone等首次用exosome来描述网织红细胞分泌的这种囊性小泡 ...

Association of APOE genotype with academic and physical education performance; The role of TREM2/DAP12 complex in microglial signaling pathway [PDF]

open access: yes, 2017
载脂蛋白E(apolipoproteinE,apoE)是脑中主要的载脂蛋白及胆固醇运载体。人类APOE基因具有多态性,包含了APOEɛ2、ɛ3和ɛ4三种亚型。其中,ɛ4等位基因是引起晚发型阿尔茨海默病(Late-onsetAlzheimer’sDisease)最重要的危险因素。尽管许多研究表明在老年人中APOE基因的多态性与认知功能密切相关,但其对青少年群体认知功能的影响研究非常少,并且有限的研究结果存在争议性。为了进一步探讨APOE基因多态性对儿童认知功能的影响,
