摘要 目的探讨抑肽酶对肿瘤坏死因子-α(TNF-α)活化人脐静脉内皮细胞的作用。方法采用Ficoll液提取高纯度的健康成人中性粒细胞(PMN)。体外培养的人脐静脉内皮细胞随机分为3 组,对照组(C组):给予等量培养液;TNF-α活化组(T组):给予TNF-α 2 ng/ml,作用时间5 h;抑肽酶+ TNF-α组(A+T组):给予抑肽酶250 KIU/ml,作用时间6 h,1 h后给予TNF-α2 ng/ml,作用时间5 h。用细胞培养小室测定PMN跨迁单层融合的人脐静脉内皮细胞的迁移率,采用免疫细胞化学法测定人脐静脉内皮细胞细胞间黏附分子-1(ICAM-1)以及细胞连接蛋白β-链蛋白的表达。结果与C组比较, T A+T组ICAM-1表达和PMN迁移率增加,β-链蛋白表达下降(P<0.05);与T组比较,A+T组 ICAM-1表达和PMN迁移率降低,β-链蛋白表达增多(P<0.05)。结论抑肽酶可抑制TNF-α对人脐静脉内皮细胞的活化。
