摘要 目的:研究唾液支原体感染牙龈上皮细胞(HEGC)后,人β防御素-2(hBD-2)的表达和IL-1β、IL-8的产生情况,以及这两者是否与NF-κB的激活有关。方法:HGEC经口腔支原体刺激后,RT-PCR检测hBD-2 mRNA表达,ELISA检测细胞因子的产生,Western blot分析NF-κB的激活情况。结果:HGEC经唾液支原体刺激3 h后能经NF-κB产生IL-8。同时唾液支原体也能以非NF-κB依赖性方式诱导hBD-2表达。IL-8的产生与hBD-2 mRNA的表达存在一定相关性。结论:hBD-2的非NF-κB依赖性表达可能与初始的炎症反应有关,IL-8的产生可能通过自分泌机制影响到上皮细胞表达hBD-2 mRNA的表达。
