J Periodontol:口服波耳丁可抑制牙槽骨吸收,用于牙周炎的治疗

在牙周炎期间,当被称为核因子κB配体的受体激活物(RANKL)表达增加时,牙槽骨会被吸收。在受牙周炎影响的组织中,T-helper-17型(Th17)和T-调节型(Treg)淋巴细胞活性之间的不平衡有利于这种RANKL的过度表达。在这种情况下,旨在调节这种Th17/Treg失衡的免疫治疗策略可以最终阻止RANKL介导的牙槽骨丧失。

 

据报道,波耳丁可保护类风湿性关节炎骨质疏松症期间的病理性骨丧失,其发病机制与Th17/Treg失衡有关。然而,黑胆碱对牙周炎期间牙槽骨吸收的影响尚未阐明。本研究旨在确定波耳丁是否通过调节牙周炎期间Th17/Treg失衡抑制牙槽骨吸收,研究结果已在线发表于J Periodontol。

对结扎诱导的牙周炎小鼠进行连续15天的口服波耳丁(10/20/40 mg/kg)治疗。未治疗的牙周炎影响的小鼠和未结扎的小鼠作为对照。通过显微计算机断层扫描和扫描电子显微镜分析牙槽骨损失。通过组织学鉴定抗酒石酸酸性磷酸酶阳性细胞来量化破骨细胞。通过ELISA、定量聚合酶链反应(qPCR)和免疫组化分析RANKL及其竞争性拮抗剂骨保护素(OPG)的产生。通过流式细胞仪量化T细胞频率和数量,分析Th17和Treg反应。同时,通过qPCR定量分析其标志性转录因子和细胞因子的表达。

 

结果显示,波耳丁抑制了牙槽骨的吸收。牙周炎组织中,波耳丁导致破骨细胞数量和RANKL/OPG比例降低。此外,在牙周炎周围组织中,波耳丁降低了Th17-淋巴细胞的检测和反应,增加了Treg-淋巴细胞的检测和反应。

 

综上所述,该研究结果表明,口服波耳丁可抑制牙槽骨吸收,调节实验性牙周炎期间Th17/Treg的失衡。
