摘要:

Nogo-A是一种重要的髓鞘相关生长抑制因子,在成体动物中枢神经系统损伤再生中发挥了关键的抑制作用。近年来许多研究表明, Nogo-A及其受体NgR可以影响淀粉样蛋白Aβ的代谢,其下游的ROCK激酶可以影响Aβ、tau蛋白的水平以及血脑屏障的通透性,这些均提示Nogo-A及其受体与阿尔茨海默病(AD)的发病机制有着密切的联系。此外,最近的研究还发现了Nogo-A的另外两种受体PirB和S1PR2,可能为Nogo-A在神经系统疾病中的作用提供新的研究方向。我们将着重阐释Nogo-A及其受体的基本结构和功能的新发现,以及其在AD中的作用等方面的最新研究进展。

Abstract:

Nogo-A is an important myelin associated inhibitory factor, which creates a critical barrier to the central nervous system regeneration after injury. Recent research shows that Nogo-A/Nogo-A receptors can affect the metabolism of amyloid-β-protein (Aβ), and its downstream ROCK kinase. It can modulate the level of Aβ and tau protein, as well as the permeability of blood brain barrier. These findings suggest that Nogo-A/Nogo-A receptors have a close relationship with Alzheimer’s disease (AD). Moreover, two new receptors of Nogo-A, PirB and S1PR2, have been identified recently. The identification of these two receptors may provide new insight into the mechanism of Nogo-A involving in the progress of central nervous diseases. we focuses on the up-to-date knowledge of the basic structure and function of Nogo-A/Nogo-A receptors and their role in AD pathogenesis.
