摘要:
随着全球老龄化程度加剧,老年神经变性疾病发病率显著增高。其中,阿尔茨海默病(Alzheimer's disease,AD)是目前最常见的神经变性疾病,已成为当下的全球公共卫生难题。AD相关的核心病理改变主要包括细胞外β淀粉样蛋白(Amyloid-β,Aβ)沉积与细胞内神经纤维缠结(neurofibrillary tangles,NFT),在出现临床症状前数十年就已存在[1]。因此,神经病理学检查是定义AD的金标准。

摘要:
阿尔茨海默病(AD)是一种隐匿起病、缓慢进行性恶化的神经退行性疾病.到目前为止,AD的发病机制尚未完全阐明.β-淀粉样蛋白(Aβ)聚集、斑块形成和过度磷酸化tau形成神经原纤维缠结(NFTs)是AD特有的神经病理标志.外泌体是直径为50~100 nm的膜性囊泡,在细胞间物质交换及信号转导中起重要作用,对神经发育、活化和再生具有广泛影响.近年来,外泌体与AD相关研究成为热点,这为AD的早期诊断、机制研究和药物开发提供新的思路.本文综述了外泌体的基本功能及其在AD发病机制中的作用,着重于外泌体对于A[β和Tau病理过程的影响.

摘要:
Alzheimer′s disease(AD),is the commonest reason of dementia in elderly populations mostly affecting beyond the age of 65,and the fatality rate has also been increasing with a rapid growth.The pathogenesis of AD is unclear, and is generally considered to be caused by accumulation of amyloid-β(Aβ)plaques,hyperphosphorylation of Tau protein in neurons,and disorder of cholinergic receptor.Up to now,most clinical treatments are symptomatic treatments,which can-not reverse the process of disease.In recent years,a number of medicinal plants and natural products isolated from them have exhibited potential effect on AD.With the multiple targets and fewer adverse effects, natural products gradually become important sources of new drugs.%阿尔茨海默病(AD)是老龄人口(>65岁)痴呆的最常见原因,致死率逐年升高.AD的发病机制尚不明确,普遍认为是由于淀粉样蛋白β(Aβ)沉积、Tau蛋白磷酸化、胆碱能受体失调导致的.对于此病,临床大多采用对症治疗,目前尚无逆转疾病进程的药物.近年来,人们发现了一系列的药用植物及从中分离得到的天然产物在AD防治中展现出潜在的治疗作用,天然产物来源的药物具有多靶点、相对不良反应小的优势,逐渐成为医药工作者的重点开发对象.

摘要:
大脑神经纤维缠结(NFTs)是阿尔茨海默病(AD)的标志性病变之一,由磷酸化tau蛋白(p-tau)构成.最近在慢性创伤性脑病(CTE)患者中发现,其他神经退行性病中也具有神经纤维缠结(NFTs)的特点.tau蛋白病变是颅脑损伤(TBI)相关AD和CTE的病因,顺式p-tau蛋白是脑损伤后神经退行性病变的一个早期驱动因子.顺式p-tau蛋白可促使tau蛋白病理化,并且在人体中检测顺式p-tau蛋白可能提供全新的诊断方法及预后措施.此外,个体化的顺式p-tau蛋白抗体最终可能发展为一项治疗AD、TBI及CTE的全新方案.文章对tau蛋白在TBI及神经退行性病中的作用机制、顺式P-tau蛋白的形成、顺式tau蛋白化的作用及顺式p-tau抗体治疗进行综述.%One of the common hallmark lesions of Alzheimer's disease (AD) brains is neurofibrillary tangles(NFTs), which are composed of phosphorylated tau protein (p-tau).NFTs are also a defining feature of other neurodegenerative disorders and have recently been identified in the patients suffering from chronic traumatic encephalopathy (CTE).Tau protein pathological change is the etiological factor of AD and CTE after traumatic brain injury (TBI), and CIS p-tau is an early driving factor of neurodegeneration after brain injury.CIS p-tau can induce tau protein pathology, and the detection of CIS p-tau in human may provide new diagnostic methods and prognostic measures.Furthermore, the individualized cis p-tau antibody could ultimately be developed as a new treatment for AD, TBI and CTE.This article reviews the mechanism of tau protein in TBI and neurodegeneration, the formation of CIS P-tau protein, the role of cistauosis and the progress of CIS p-tau antibody therapy.

摘要:
人多能干细胞(pluripotent stem cells,PSCs)为研究人类疾病如阿尔茨海默病(Alzheimer’s disease,AD)的物种特异性提供了独特的工具。然而,神经元的体外培养剥夺了它们原本生长的自然环境。于是Espuny-Camacho等将人PSCs源性皮层神经元前体细胞移植入AD模型小鼠的脑中,结果发现,人类神经元能够分化并融合到宿主脑中.

摘要:
AIM: To investigate the effects of Scutellaria barbata flavonoids (SBF) on neurofibrillary tangle (NFT) aggregation, tau protein phosphorylation and the regulated mechanism of glycogen synthase kinase (GSK) 3βand protein phosphatase (PP) 2A in the rats induced by amyloid βprotein 25-35 (Aβ25-35) in combination with AlCl3 and re-combinant human transforming growth factor ( RHTGF)-β1( composited Aβ) .METHODS:The male SD rats were used to establish the simulated Alzheimer disease ( AD) model by intracerebroventricular injection of composited Aβ.The Morris water maze was applied for screening the successful model rats with learning and memory deficits .The successful model rats were daily and orally administrated with SBF at doses of 35, 70 and 140 mg/kg or positive control drug Ginkgo biloba leaves flavonoids ( GLF) at 140 mg/kg for 37 d.The silver nitrate staining was used to determine the cortical NFT .The protein levels of total tau, phosphorylated protein of tau at Ser199 and Ser214 sites, GSK3βand PP2A in hippocampus and cortex were determined by Western blot .The mRNA expression of GSK3βand PP2A in the hippocampus and cortex was detected by RT-PCR.RESULTS:Compared with sham group , the cell number of positive NFT with silver nitrate staining in model rat cerebral cortex was significantly increased .The protein levels of phosphorylated tau protein at Ser 199 and Ser214 sites, GSK3βin the hippocampus and cerebral cortex in the model rats dramatically elevated , and PP2A was marked decreased as compared with the sham group rats.Meanwhile, the mRNA expression of GSK-3βsignificantly increased but PP2A was de-creased.However, these above abnormalities were differently attenuated by treating with SBF at different doses or GLF at 140 mg/kg for 37 d.CONCLUSION: SBF suppresses the NFT aggregation by inhibition of the regulatory functions of GSK-3βand PP2A, thus reducing the phosphorylation of tau protein .%目的:探讨半枝莲黄酮(SBF)对复合Aβ,即β淀粉样蛋白25-35(Aβ25-35)联合三氯化铝(AlCl3)和重组人类转化生长因子-β1(RHTGF-β1)所致大鼠脑内神经元纤维缠结(NFT)沉积,tau蛋白磷酸化的影响及糖原合成激酶(GSK)3β和蛋白磷酸酶(PP)2A的调节机制。方法:雄性SD大鼠,脑室注射复合Aβ建立拟阿尔茨海默病( AD)大鼠记忆障碍模型,Morris水迷宫进行记忆障碍模型筛选,模型成功大鼠灌胃35、70和140 mg/kg的SBF和140 mg/kg的阳性对照药银杏叶黄酮( GLF),持续37 d。硝酸银法测定大鼠大脑皮层的NFT,Western blot法检测大鼠海马、皮层中总tau蛋白、Ser199和Ser214位点磷酸化的tau蛋白水平以及相关GSK3β和PP2A蛋白的表达水平。 RT-PCR法检测海马、皮层中GSK3β和PP2A的mRNA水平。结果:大鼠脑室注射复合Aβ可以引起大鼠脑内NFT生成增加、Ser199和Ser214位点磷酸化tau蛋白、GSK3β蛋白和mRNA表达水平皆明显增加,PP2A的蛋白和mRNA表达水平明显降低。3种剂量的SBF灌胃37 d不同程度地逆转复合Aβ所致大鼠脑内上述异常改变。 GLF也表现出与SBF相似的结果。结论: SBF 能够抑制复合Aβ所致大鼠脑内NFT 沉积,该作用可能是通过抑制GSK3β活性、增加PP2A活性从而降低tau蛋白磷酸化而实现的。
