14,15-环氧化二十碳三烯酸对糖氧剥夺/复氧诱导的BV2细胞炎症反应的影响

摘要

目的 观察14,15-环氧化二十碳三烯酸(14,15-EET)对糖氧剥夺/复氧(OGD/R)诱导的BV2小鼠小胶质细胞炎症反应的影响.方法 将BV2细胞随机分为空白对照组、溶剂对照纽及14,15-EET干预组.在14,15-EET的干预作用下,利用酶联免疫吸附测定(ELISA)法测定BV2细胞OGD1h后复糖复氧0,3,6,12,24h时细胞培养液中肿瘤坏死因子-α(TNF-α)的浓度;并用噻唑蓝(MTT)实验检测其各时间点细胞活性的改变.同样条件下,Transwell细胞迁移实验用来观察BV2细胞的迁移能力变化.结果 与溶剂对照组比较,14,15-EET干预组BV2细胞培养液中分泌的炎症因子浓度显著减少;细胞活性明显降低;迁移能力显著减弱.以上结果均以OGD1h/R12h最具统计学意义.结论 14,15-EET对BV2细胞OGD再灌注损伤后的炎症反应具有一定的抑制作用.%Objective To explore the effect of 14,15-epoxyeicosatrienoic acids (14,15-EET) on the inflammatory response of BV2 cells under oxygen and glucose depriviation/reoxygenation (OGD/R) conditions.Methods BV2 cells were randomly divided into three groups,blank control group,vehicle control group,and 14,15-EET group.Under treatment of 14,15-EET,the concentration of inflammatory factor in BV2 cell culture media was detected by ELISA at different time points (reoxygenation for 0,3,6,12,24 h) after OGD1h.The viability of BV2 cells was detected by MTT assay at different time points.At the same conditions,using Transwell migration experiment,migration ability of BV2 cells was observed.Results The 14,15-EET group had the lower levels of inflammatory factor secretion,lower viability and weaker ability of migration than the vehicle control group.The above results were most statistically significant at OGD1h/R12h.Conclusion 14,15-EET can inhibit the inflammation of BV2 cells induced by the injury of OGD reperfusion.
