本研究旨在确定牙髓卟啉单胞菌是否可以重新激活潜伏的EB病毒(EBV)。

使用高效液相色谱法测定牙周牙龈成纤维细胞上清液中短链脂肪酸(SCFAs)的浓度。将BamHI片段Z左侧开放阅读框1(BZLF-1)的启动子区域克隆到萤光素酶表达载体中。然后,使用牙髓卟啉单胞菌培养物上清液进行萤光素酶测定。使用蛋白质印迹检查牙髓卟啉单胞菌培养物上清液处理的Daudi细胞的组蛋白乙酰化。使用实时聚合酶链式反应(PCR)和Western印迹法定量检测BZLF-1 mRNA和BamHI片段Z EB复制活化剂(ZEBRA)蛋白的表达。使用定量实时PCR检查手术切除的根尖周肉芽肿,以检测牙髓牙髓细胞,EBV DNA和BZLF-1 mRNA的表达。使用Steel测试进行统计分析。

结果显示,牙周真菌培养上清液中正丁酸的浓度明显高于其他SCFAs(P = 0.0173)。使用牙髓卟啉单胞菌培养上清液处理的B-95-8-221Luc细胞,萤光素酶测定证明牙髓卟啉单胞菌诱导BZLF-1的表达。培养上清液也观察到组蛋白的超乙酰化。牙髓卟啉单胞菌培养上清液处理后,Daudi细胞以剂量依赖性方式表达BZLF-1mRNA和ZEBRA蛋白。牙周炎和BZLF-1在根尖周肉芽肿中也有检测到。BZLF-1mRNA的表达水平与每个标本中的牙周牙髓细胞的数目相似。

综上所述,该研究结果表明,牙髓卟啉单胞菌产生的正丁酸可再活化潜伏EBV。
