摘要:

目的研究一氧化碳对炎性环境下人牙龈成纤维细胞黏附分子表达的影响。方法以50 ng·mL-1的肿瘤坏死因子(TNF)-α和10 ng·mL-1的白细胞介素(IL)-1β刺激加入或不加入500 μmol·L-1一氧化碳释放分子(CORM)的人牙龈成纤维细胞,用Western blot法检测细胞间黏附分子(ICAM)-1、血管细胞黏附分子(VCAM)-1的蛋白表达,用逆转录多聚酶链反应(RT-PCR)检测黏附分子的mRNA表达,用瞬时转染和报告基因测定法分析NF-κB的活性。结果TNF-α和IL-1β共同刺激后,人牙龈成纤维细胞ICAM-1和VCAM-1的mRNA表达和蛋白表达均显著增强。CORM的加入可显著抑制ICAM-1和VCAM-1的表达。CORM可显著降低ICAM-1和VCAM-1诱导的NF-κB的活性。结论一氧化碳有可能成为牙周病治疗的一种极具潜力的新物质。

Abstract:

Objective To investigate the influence of carbon monoxide on the expression of adhesion moleculesstimulated by inflammatory cytokines on human gingival fibroblasts. Methods Human gingival fibroblasts were stimulatedwith 50 ng·mL-1 tumor necrosis factor(TNF)-α and 10 ng·mL-1 interleukin(IL)-1β concurrently in the presenceor absence of 500 μmol·L-1 carbon monoxide releasing molecule(CORM). Expression of intercellular adhesion molecule(ICAM)-1, vascular cell adhesion molecule(VCAM)-1 at protein and mRNA level was examined by Western blot andreverse transcription polymerase chain reaction(RT-PCR), respectively. Activity of transcription factor NF-κB was evaluatedby reporter gene assay. Results Expression of ICAM-1 and VCAM-1 on human gingival fibroblasts increaseddramatically after concurrent stimulation of TNF-α and IL-1β, while CORM inhibited the upregulation of ICAM-1 andVCAM-1. CORM decreased the activity of NF-κB stimulated by TNF-α and IL-1β. Conclusion Carbon monoxidecould be a promising way in treating of periodontitis.
