摘要 细胞培养、动物实验、临床实验都有证据表明 ,n 3多不饱和脂肪酸或鱼油的补充能改善一些免疫性疾病 ,抑制炎症反应。其机制包括 :n 3多不饱和脂肪酸 (EPA、DHA )能置换细胞膜磷脂中的花生四烯酸 (AA ,n 6 ) ,竞争环氧酶和脂氧合酶从而减少来源于AA的炎性介质 ,减轻炎症反应 :n 3多不饱和脂肪酸也可通过改变细胞膜磷脂脂肪酸构成来影响细胞膜流动性 ,膜上相关信号分子、酶、受体的功能 ,从而改变信号转导过程。此外 ,通过影响酶或细胞因子的基因表达、抑制促炎症因子产生、调节黏附分子表达来调节免疫功能 ,这种机制可不依赖类二十烷酸物质的产生。鱼油中富含的EPA(C2 0∶5,n 3)和DHA (C2 2∶6,n 3)抑制炎症和免疫的作用最为显著。
