膳食必需PUFA二十二碳六烯酸[DHA;[22:6(n-3)]是神经系统细胞结构和功能的关键贡献者,DHA丰度不足与衰老和神经退行性疾病期间的认知能力下降有关。最近的研究强调了dha来源的神经保护素D1 (NPD1)在大脑细胞存活和修复的稳态调节中的重要性,包括神经营养、抗凋亡和抗炎信号。新出现的证据表明,NPD1的合成是由生长因子和神经营养因子激活的。不断发展的研究表明,NPD1与影响b-淀粉样蛋白前体蛋白(bAPP)和淀粉样蛋白β (Ab)肽神经生物学的分子遗传机制具有重要的决定和调节作用。DHA缺乏或其过氧化作用似乎与阿尔茨海默病(AD)中的炎症信号、细胞凋亡和神经元功能障碍有关,阿尔茨海默病是一种常见的、进行性的与年龄相关的神经系统疾病,是人类大脑结构和过程所特有的。本文简要回顾了我们目前对DHA和NPD1在bAPP加工和Ab肽信号传导中的相互作用的理解,以及这如何促进衰老和AD病理特征的氧化和致病过程。
The dietary essential PUFA docosahexaenoic acid [DHA; 22:6(n-3)] is a critical contributor to cell structure and function in the nervous system, and deficits in DHA abundance are associated with cognitive decline during aging and in neurodegenerative disease. Recent studies underscore the importance of DHA-derived neuroprotectin D1 (NPD1) in the homeostatic regulation of brain cell survival and repair involving neurotrophic, antiapoptotic and antiinflammatory signaling. Emerging evidence suggests that NPD1 synthesis is activated by growth factors and neurotrophins. Evolving research indicates that NPD1 has important determinant and regulatory interactions with the molecular-genetic mechanisms affecting b-amyloid precursor protein (bAPP) and amyloid beta (Ab) peptide neurobiology. Deficits in DHA or its peroxidation appear to contribute to inflammatory signaling, apoptosis, and neuronal dysfunction in Alzheimer disease (AD), a common and progressive age-related neurological disorder unique to structures and processes of the human brain. This article briefly reviews our current understanding of the interactions of DHA and NPD1 on bAPP processing and Ab peptide signaling and how this contributes to oxidative and pathogenic processes characteristic of aging and AD pathology.
