多不饱和脂肪酸(Polyunsaturated Fatty Acid, PUFA)在大脑发育和功能中发挥着不可或缺的作用。近年来,PUFA与神经系统疾病之间的关系备受关注,尤其是其对血脑屏障(Blood-Brain Barrier, BBB)功能的影响。研究发现,PUFA状态的异常与多种神经精神疾病如重度抑郁症、双相情感障碍、精神分裂症、阿尔茨海默病和注意缺陷多动障碍等密切相关。本文综述了当前关于PUFA通过BBB进入中枢神经系统(Central Nervous System, CNS)的转运机制的研究进展,并探讨了n-3 PUFA与抑郁症之间的潜在关系。Polyunsaturated Fatty Acids (PUFAs) play an indispensable role in brain development and function. In recent years, the relationship between PUFAs and neurological disorders has garnered significant attention, particularly their influence on Blood-Brain Barrier (BBB) function. Research has revealed that aberrant PUFA status is closely associated with various neuropsychiatric disorders, including major depressive disorder, bipolar disorder, schizophrenia, Alzheimer’s disease, and attention-deficit/hyperactivity disorder. This review summarizes the current advancements in the study of PUFA transport mechanisms through the BBB into the Central Nervous System (CNS) and explores the potential relationship between n-3 PUFAs and depression.
