1硫化氢通过核因子-kappa B途径抑制肿瘤坏死因子alpha诱导的角质形成细胞的炎症反应显示文摘目的:探讨外源性硫化氢(Hydrogen sulfide,H2S)对肿瘤坏死因子alpha(Tumor necrosis factor alpha,TNF-α)诱导的角质形成细胞分泌炎症因子白细胞介素6(Interleukin 6,IL-6)、白细胞介素8(Interleukin 8,IL-8)以及一氧化氮(Nitric oxide,NO)的影响,并探讨核转录因子kappa B(Nuclear factor kappa B,NF-κB)信号通路途径是否参与此过程。方法:应用TNF-α诱导HaCat细胞分泌炎症因子,以硫氢化钠(Sodium hydrosulfide,NaHS)作为H2S的供体,设置不同浓度的量效组。采用ELISA法测定HaCat细胞分泌IL-6和IL-8的水平,RT-PCR法检测HaCat细胞IL-6和IL-8的mRNA水平,Griess法检测HaCat细胞分泌NO水平,Western blot检测HaCat细胞胞内诱导型一氧化氮合酶(Inducible nitric oxide synthase,iNOS)、磷酸化I-kappa B-alpha(Phosphorylation of I-kappa B-alpha,p-IKB-α)和胞核内NF-κB P65水平。结果:10 ng/ml的TNF-α能显著诱导HaCat细胞内IL-6和IL-8因子的转录和分泌,培养上清NO产量和胞内iNOS含量明显增高,胞内p-IKB-α和胞核P65水平明显提高。在TNF-α诱导HaCat细胞前1 h,给与20~400μmol/L的NaHS做预处理,结果显示NaHS呈剂量依赖性地抑制HaCat细胞分泌IL-6、IL-8和NO,并能部分抑制NF-κB信号通路的活化。结论:H2S通过抑制NF-κB信号通路的活化来抑制TNF-α诱导角质形成细胞的炎症反应。Ammar K H Alshorafa 郭庆 曾凡钦 陈敏春 谭国珍 唐增奇 尹若菲 2011重庆医科大学学报2011,36,10:3
