The study on protein level, lipidation state and protein stability of apolipoprotein E [PDF]
阿尔兹海默症(Alzheimer’sdisease,AD)是老年人群中最常见的痴呆类型。按AD的发病年龄可以将AD划分为早发型AD和晚发型AD,绝大多数的AD病人属于晚发型AD。载脂蛋白E(apoE)存在ε2、ε3、ε4三种常见的等位基因,其中的ε4等位基因是晚发型AD最重要的危险因素,而ε2等位基因可以降低人类罹患阿尔兹海默症的风险。ApoE是脑中主要的载脂蛋白,在脑中胆固醇及其它脂质的运输过程中发挥重要作用。ApoE通过调节Aβ的清除及脂质转运等机制在AD的病理学过程中发挥重要作用 ...

The phosphorylation of BAG3 by CDK5 and its roles in astrocytes [PDF]
细胞周期素依赖性蛋白激酶5(Cyclin-DependentKinase5,CDK5)是细胞周期蛋白依赖性丝氨酸/苏氨酸蛋白激酶家族中的一个成员,在神经系统的发育中发挥了至关重要的作用。CDK5的调节亚基P35、P39是神经系统特异性表达的蛋白,因此赋予了CDK5在神经系统中特异的激酶活性,使CDK5在调控神经递质传递,神经元凋亡等方面发挥了重要作用。对于CDK5的研究一直集中在对其新底物的发现和鉴定上,至今为止有40余个CDK5的底物被鉴定出来。作为脯氨酸依赖性蛋白激酶,CDK5可以特异磷酸化包含有 ...

Effects of ApoE Isoforms Expression on Brain ApoE Lipidation and Amyloid-β Accumulation [PDF]
在编码人三种不同apoE蛋白亚型(E2、E3和E4)的APOE等位基因(ε2、ε3和ε4)中,APOEε4等位基因是阿尔茨海默病(Alzheimer’sdisease,AD)最重要的遗传风险因子,APOEε2等位基因则具有保护作用。鉴于apoE蛋白亚型对基于调节apoE蛋白表达的AD治疗可能会有不同的影响,我们通过在人APOE基因定位替换(Targetedreplacement,TR)小鼠脑中过表达不同的人apoE亚型,研究脑中表达不同apoE亚型对apoE脂化和β-淀粉样蛋白(Amyloid-β,Aβ)

The role of MiR-23b-3p in the epileptogenesis [PDF]
癫痫是指脑部持续存在能导致癫痫反复发作,并出现相应的神经生物学、认知、心理学,以及社会学等方面的后果的脑部疾患。目前miRNA在癫痫发生发展中的作用引起越来越多的重视。miR-23b-3p是具有多种生物学作用的miRNA,如调节神经元增殖、分化和凋亡等,参与多种神经退行性疾病的病理机制。 本研究通过腹腔注射海人酸(Kainicacid,KA)构建小鼠癫痫模型,发作达到Racine标准的4-5级作为实验组纳入标准,对照组注射相同剂量的生理盐水,并应用荧光定量PCR法对皮层和海马组织中miR-23b-3p ...

Menin mediates Tat-induced neuronal apoptosis in Tat-treated cells and in brain frontal cortex of SIV-infected macaques [PDF]
神经元凋亡是人类免疫缺陷病毒相关神经认知紊乱(HumanImmunodeficiencyVirus-AssociatedNeurocognitiveDisorder,HAND)的主要病理特征。神经元凋亡与HIV-1Tat蛋白(简称Tat)有关,但具体机制尚不十分清楚。最近的研究表明:Tat的反式激活需要多发性内分泌肿瘤Ⅰ型(MEN1)肿瘤抑制蛋白menin参与,提示menin可能参与到Tat诱导的神经元损伤中。本研究从细胞实验、SIV感染恒河猴动物模型两个层面,使用Westernblot、TUNEL染色、
