糖原合成酶激酶3 (GSK3)是一种具有组成性活性的脯氨酸定向丝氨酸/苏氨酸激酶,在糖原代谢和基因转录等一系列生理过程中发挥作用。GSK3在散发性和家族性阿尔茨海默病(AD)的发病机制中也起着关键和核心作用,这一观察结果使我们提出了“AD的GSK3假说”。根据这一假说,GSK3的过度活性导致记忆障碍、tau蛋白过度磷酸化、β-淀粉样蛋白产生增加和局部斑块相关的小胶质细胞介导的炎症反应;这些都是阿尔茨海默病的标志性特征。如果我们的“AD的GSK3假说”得到证实,并且GSK3确实是AD的因果介质,那么GSK3抑制剂将为这种破坏性疾病的治疗干预提供新的途径。
Glycogen synthase kinase 3 (GSK3) is a constitutively active, proline-directed serine/threonine kinase that plays a part in a number of physiological processes ranging from glycogen metabolism to gene transcription. GSK3 also plays a pivotal and central role in the pathogenesis of both sporadic and familial forms of Alzheimer's disease (AD), an observation that has led us to coin the ‘GSK3 hypothesis of AD’. According to this hypothesis, over-activity of GSK3 accounts for memory impairment, tau hyper-phosphorylation, increased β-amyloid production and local plaque-associated microglial-mediated inflammatory responses; all of which are hallmark characteristics of AD. If our ‘GSK3 hypothesis of AD’ is substantiated and GSK3 is indeed a causal mediator of AD then inhibitors of GSK3 would provide a novel avenue for therapeutic intervention in this devastating disorder.
