基底前脑胆碱能系统依赖神经生长因子(NGF)的营养支持来维持其表型和功能。在阿尔茨海默病 (AD) 中,基底前脑胆碱能神经元 (BFCN) 会发生进行性萎缩,表明 NGF 营养支持存在缺陷。在中枢神经系统内,NGF 的成熟和降解受到活性依赖性代谢级联的严格调控。在这里,我们简要概述了唐氏综合症 (DS) 中阿尔茨海默氏病的病理学特征,重点是在阿尔茨海默氏病病理学演变过程中 NGF 代谢途径的破坏。这种 NGF 代谢障碍在具有晚期病理学的阿尔茨海默氏症大脑中已得到证实,并且在轻度认知障碍 (MCI) 和大脑淀粉样蛋白水平升高的非痴呆个体中也观察到。随着 DS 患者不可避免地发展为 AD,我们随后回顾了支持 DS 中存在类似 NGF 代谢障碍且与基底前脑胆碱能系统萎缩同时发生的研究结果。最后,我们讨论了 NGF 相关生物标志物作为 DS 中不断发展的阿尔茨海默病病理学指标的潜力。
The basal forebrain cholinergic system relies on trophic support by nerve growth factor (NGF) to maintain its phenotype and function. In Alzheimer’s disease (AD), basal forebrain cholinergic neurons (BFCNs) undergo progressive atrophy, suggesting a deficit in NGF trophic support. Within the central nervous system, NGF maturation and degradation are tightly regulated by an activity-dependent metabolic cascade. Here, we present a brief overview of the characteristics of Alzheimer’s pathology in Down syndrome (DS) with an emphasis on this NGF metabolic pathway’s disruption during the evolving Alzheimer’s pathology. Such NGF dysmetabolism is well-established in Alzheimer’s brains with advanced pathology and has been observed in mild cognitive impairment (MCI) and non-demented individuals with elevated brain amyloid levels. As individuals with DS inexorably develop AD, we then review findings that support the existence of a similar NGF dysmetabolism in DS coinciding with atrophy of the basal forebrain cholinergic system. Lastly, we discuss the potential of NGF-related biomarkers as indicators of an evolving Alzheimer’s pathology in DS.
