牙周炎是一种常见的牙科疾病,它会导致牙齿周围不可逆转的牙槽骨丢失,进而导致牙齿脱落。以前的研究主要集中在破坏宿主的细菌以及共生体对其定植的促进作用。虽然一些针对口腔细菌的免疫反应可以保护宿主免受牙槽骨丢失的影响,但最近的研究表明,针对口腔细菌的特殊宿主防御反应可以诱导牙槽骨丢失。宿主损伤和免疫刺激口腔细菌通过诱导牙龈损伤和免疫刺激共同诱导骨丢失。在牙龈卟啉单胞菌或结扎法诱导的实验性牙周炎小鼠模型中,γ蛋白细菌积累并刺激宿主免疫反应,以诱导宿主损伤。在这里,我们回顾了不同的细菌群在通过诱导宿主损伤和免疫刺激促进骨丢失方面的不同作用。
Periodontitis is a common dental disease which results in irreversible alveolar bone loss around teeth, and subsequent tooth loss. Previous studies have focused on bacteria that damage the host and the roles of commensals to facilitate their colonization. Although some immune responses targeting oral bacteria protect the host from alveolar bone loss, recent studies show that particular host defense responses to oral bacteria can induce alveolar bone loss. Host damaging and immunostimulatory oral bacteria cooperatively induce bone loss by inducing gingival damage followed by immunostimulation. In mouse models of experimental periodontitis induced by either Porphyromonas gingivalis or ligature, γ-proteobacteria accumulate and stimulate host immune responses to induce host damage. Here we review the differential roles of individual bacterial groups in promoting bone loss through the induction of host damage and immunostimulation.
