摘要 本文从细胞生物学的角度综述多不饱和脂肪酸(polyunsaturated fatty acids,PUFAs)改善大脑功能的作用机理,包括PUFAs促进神经细胞生成(neurogenesis)、维持神经细胞形态和功能、促进神经突生长、防止神经细胞变性(neurodegeneration)、抑制神经细胞凋亡(apoptosis),以及调节神经细胞膜流动性和可塑性(plasticity)、端粒(telomere)活性等作用机制,为PUFAs的营养干预研究应用,特别是应用于保护大脑正常功能,防止生理性衰老和疾病性脑功能障碍(如阿尔兹海默氏症和帕金森症)所致的脑功能障碍提供参考。 The protective effects of polyunsaturated fatty acids(PUFAs) on brain function and the nervous system have attracted a lot of attention. Numerous studies have illustrated the anti-inflammation, anti-oxidative and cardiovascular protective effects of PUFAs, as well as the protective effects on brain function, particularly nerve cells. In this article, we review the mechanisms of brain-protective effects of PUFAs in following fields: how PUFAs promote neurogenesis, maintain nerve cell morphology and function, improve neurite growth; prevent neurodegeneration, depress nerve cell apoptosis and regulate membrane fluidity, plasticity and telomere activity in neurons. This review provides a prospective insight on nutritional studies of PUFAs against aging and/or diseases(such as Alzheimer's disease and Parkinson's disease) inducing brain disorders.
