CysLT2受体拮抗剂HAMI3379抑制LPS诱导小鼠小胶质瘤细胞系的炎性反应
发布时间:2021-04-25 12:00
目的探究半胱氨酰白三烯2(Cys LT2)受体拮抗剂HAMI3379对LPS诱导小鼠小胶质细胞(BV-2)炎性反应的调控作用及其可能的作用机制。方法体外培养BV-2,将BV-2分为对照组、LPS(100 ng/m L)组、HAMI3379(0. 01、0. 1和1μmol/m L)组和LPS+HAMI3379组。CCK-8法检测BV-2细胞的增殖; ELISA检测细胞上清液中炎性因子IL-1β、TNF-α、IL-10的含量; Western-blot检测PKCα、IKBα、NF-κB p50和p65蛋白的表达。结果 LPS能够激活BV-2细胞,促进其细胞的增殖(P<0. 05);显著增加细胞上清液中炎性因子IL-1β、TNF-α的分泌,减少IL-10的分泌(P<0. 05);且显著上调PKCα、IKBα、p65蛋白的表达水平(P<0. 05)。Cys LT2受体拮抗剂HAMI3379能够显著减轻上述变化(P<0. 05)。结论 Cys LT2受体拮抗剂HAMI3379能够抑制LPS激活BV-2细胞,抑制炎性反应,其作用机制可能与抑制PKCα/NF-κB信号通路有...
