Biochem/physiol Actions

花生四烯酸 (AA) 是一种 ω6 不饱和脂肪酸，是细胞膜磷脂的组分。在炎症反应中，水解磷脂酶 A2 可将 AA 从膜磷脂中释放出来。然后，AA 可被至少两种环加氧酶 (COX) 亚型代谢为前列腺素和血栓烷，被脂氧合酶代谢为白三烯和脂氧素，以及通过细胞色素 p450 催化代谢为环氧-二十碳三烯酸。AA 及其代谢产物在多种生物过程中发挥着重要作用，包括信号转导、平滑肌收缩、趋化性、细胞增殖和分化，以及细胞凋亡。已证实 AA 可与 G 蛋白的亚基结合，抑制 Ras GTP 酶激活蛋白 (GAP) 的活性。AA 的细胞摄取需要消耗能量并涉及跨细胞质膜的蛋白质辅助运输。

High-density lipoprotein (HDL) can induce cyclooxygenase-2 (COX-2) expression and prostacyclin I-2 (PGI-2) release in endothelial cells to exert multiple antiatherogenic functions. This effect has been attributed mainly to the role of sphingosine-1-phosphate (S1P) integrated in HDL. However, whether apolipoprotein A-I
