摘要
目的:探讨肿瘤坏死因子-α(TNF-α)对人滑膜成纤维细胞(human fibroblast-like synovicyte,HFLS)白细胞介素-37(IL-37)表达的影响。方法:不同浓度TNF-α与HFLS作用,作用不同时间后,用实时荧光定量逆转录聚合酶链式反应,检测HFLS中IL-37mRNA的表达。结果:TNF-α上调HFLS的IL-37mRNA表达,并呈一定的时间、剂量依赖关系。结论:TNF-α诱导HFLS的IL-37上调表达,为进一步探索HFLSIL-37参与类风湿关节炎的炎症反应提供了实验依据。
Objective To investigate the expression of interleukin 37 (IL-37) in human fibroblast-like synovicyte (HFLS) modulated by TNF-α. Methods The HFLS were treated with different dose of TNF-α at different time periods. The expressions of IL-37 mRNA in HFLS were detected by reverse transcriptase-eonpled quantitative real-time PCR (real-time RT-PCR) analysis. Results The results showed that TNF-α could up- regulate the HFLS IL-37 mRNA expression, which had time-and dose-dependent relationship. Conclusion TNF-α induces IL-37 expression in HFLS, which provides the experiment basis for further study of the potential involvement of HFLS IL-37 in the inflammation response of rheumatoid arthritis.
