人类新研究发现,名叫FKBP52的蛋白可能会阻止Tau蛋白转向病原性。这将有利于阿尔茨海默氏症的治疗新药物的开发和在临床症状出现前检测疾病。

3月21,发表在Journal of Alzheimer's Disease杂志的一项研究表明,20年前Etienne BAULIEU教授发现的蛋白FKBP52可以防止Tau蛋白过磷酸化,Tau蛋白过磷酸化已被证明是大脑神经退行性疾病包括阿尔茨海默氏病(AD)的一大特征。

这项工作已经进行Etienne Baulieu教授和其在法国国家医学研究所的研究小组共同完成,由成立法国Baulieu研究所的慈善家资助。

有关Tau蛋白及其在AD疾病发生发展中作用的研究很少,但它是许多神经退行性疾病的病理特征就是Tau蛋白过磷酸化的形式沉积成陶蛋白缠结结构,这一点是明确的。Tau蛋白毒性的机制尚不清楚,目前有没有针对Tau蛋白的治疗药物,也没有任何标志物能预测Tau蛋白病变。Baulieu教授将研究重点放在Tau蛋白的异常上,并在2010年首次发现Tau蛋白与FKBP52蛋白之间有相互作用。

这项新的研究将他早前的研究提升到一个新的水平。研究证实:与正常脑细胞相比,阿尔茨海默氏病患者脑细胞中高水平的tau蛋白度磷酸化和FKBP52水平下降有直接的关系。这表明FKBP52可控制致病性Tau蛋白的异常产生。当AD患者的神经细胞FKBP52水平降低时,致病性Tau蛋白将不会沉积,将不能促进脑细胞的变性。

结论是,在临床症状出现之前测量FKBP52的水平形成可以用来预测阿尔茨海默氏病,调节FKBP52活动的新化合物有可能成为疾病下一代治疗药物。

Baulieu教授评论这项新研究说:年龄增长有关的大脑疾病如阿尔茨海默氏病和老年痴呆症的致病原因的研究还很缺乏,Baulieu研究所一直致力于如何预防、治疗这些疾病。

有关Tau蛋白的研究非常有限,直到最近我也只是关注Tau蛋白病理特症的少数科学家之一。FKBP52蛋白是迄今为止发现的唯一一个有抗Tau蛋白特性的蛋白。FKBP52蛋白能降低阿尔茨海默氏症患者大脑中致病性Tau蛋白的生产。

我相信这项研究使得我们向开发出一种有效治疗药物更接近了一步,有利于预测老龄化社会人群发展患阿尔茨海默氏病的可能性。(生物谷:Bioon)

Decrease of the Immunophilin FKBP52 Accumulation in Human Brains of Alzheimer's Disease and FTDP-17

Human neurodegenerative diseases characterized by abnormal intraneuronal inclusions of the tau protein, or “tauopathies”, include Alzheimer's disease (AD), Pick's disease, progressive supranuclear palsy, corticobasal degeneration as well as fronto-temporal dementia and Parkinsonism linked to chromosome 17 (FTDP-17). Several abnormalities of tau may contribute to the pathological processes, yet the mechanisms involved in tau cellular toxicity remain unclear. Previously, we demonstrated an interaction between various isoforms of tau and the immunophilin FKBP52 (FK506-Binding Protein), suggesting a direct involvement of FKBP52 in tau function. Here we analyze the expression of FKBP52 in human brains of patients with different tauopathies, including AD. Immunohistofluorescence studies carried out on cerebral cortex in different tauopathies reveal that FKBP52 is not sequestered by filamentous tau inclusions while FKBP52 is colocalized with tau in the control case brains. We found that FKBP52 expression level is abnormally low in frontal cortex of AD and FTDP-17 brains, as compared to controls, despite no alteration in the FKBP52 mRNA expression level. The possible involvement of FKBP52 in pathological tau expression/function is discussed.
