生物活性:脂氧素 A4 (LXA4) 是一种内源性脂肪氧化酶衍生的类花生酸介质,具有有效的双重促分解和抗炎特性[1]。脂氧素 A4 抑制与 ERK1/2 和 NF-kB 通路相关的人表皮角质形成细胞 (NHEK) 的增殖和炎性细胞因子/趋化因子的产生[2]。 Lipoxin A4 抑制血清淀粉样蛋白 A (SAA) 介导的 IL-8 释放,IC50 值为 25.74 nM[3]。
体外:脂氧素 A4 (LXA4) 抑制 NHEKs 中 IL-6 和 IL-8 的表达[2]。Lipoxin A4下调cyclin D1的表达[2]。Lipoxin A4还抑制NHEKs的ERK1/2磷酸化和NF-kB-p65核转位[ 2].LXA4(100 nM;预孵育 30 分钟)在有或没有 LPS(10 μg/mL)刺激的情况下抑制 NHEK 的增殖[2]。LXA4 预处理(100 nM,30 分钟)下调 LPS 诱导的角质形成细胞中 HMGB1 的分泌和表达[1]。
