消退素E1(RvE1)是生物活性脂质中特殊促消退介质(SPM)家族的一员。1 它由二十碳五烯酸(EPA;产品编号 90110|90110.1|21908)通过18-HEPE环氧化物中间体生成,该中间体是在人多形核(PMN)中性粒细胞中,由阿司匹林乙酰化的COX-2介导的EPA氧化、5-脂氧合酶(5-LO)以及白三烯A4(LTA4)水解酶作用形成的。RvE1可激活趋化因子样受体1(CMKLR1;在报告基因检测中,EC50=0.137 nM)。在酵母聚糖A(产品编号 21175)诱导的小鼠腹膜炎模型中,RvE1(20 ng/只)可抑制炎症渗出液中中性粒细胞浸润的增加。当以50 µg/kg的剂量给药时,在TNBS诱导的小鼠结肠炎模型中,它能提高生存率并防止结肠长度缩短。2 在卵清蛋白致敏的小鼠哮喘模型中,RvE1(50 µg/kg)可抑制卵清蛋白诱导的嗜酸性粒细胞和总细胞数量增加,以及支气管肺泡灌洗液(BALF)中IL-13和IgE水平的升高。3
