摘要:


文题释义:

脂多糖:是革兰阴性杆菌细胞壁特有的糖脂复合物,也是细菌的主要毒力分子。细菌是引起种植体周围炎症等多种口腔疾病的主要病因,在种植体周围组织中,脂多糖可作为抗原有效激活机体免疫反应,激活巨噬细胞,进而刺激巨噬细胞极化。
巨噬细胞:是口腔组织内重要的免疫细胞,也是异物反应的重要效应细胞,可由血液中的单核细胞分化而来,也可驻留在组织中,发挥细胞吞噬和细胞免疫作用。巨噬细胞具有高度可塑性,在微环境刺激下可极化为促炎M1型和抗炎M2型,进而影响炎症的发生和进展。


背景:随着种植技术的普及,种植体周围炎的发病率逐年升高,但其病因机制尚不明确。而高度可塑的巨噬细胞在微环境刺激下可极化为M1型和M2型,分别发挥促炎和抗炎作用,在种植体周围组织中发挥宿主防御、免疫应答和维持内环境稳态的重要作用,M1/M2巨噬细胞极化趋势与植体周围异物反应平衡息息相关。

目的:脂多糖和钛颗粒是引起种植体周围炎的重要致病因素,文章探究其对种植体周围组织中巨噬细胞极化的诱导作用。
方法:以“种植体周围炎、巨噬细胞极化、脂多糖和钛颗粒、macrophage polarization、peri-implant inflammation、peri-implantitis、LPS、TLRs、NF-κB等”为关键词在CNKI和PubMed数据库中分别进行检索,对相关文献进行筛选和整理,分析脂多糖、钛颗粒对种植体周围组织中巨噬细胞M1/M2极化的诱导作用和相关机制。

结果与结论:①脂多糖和钛颗粒可能通过Toll样受体/核因子κB等相关信号通路诱导植周组织中巨噬细胞极化,引起M1/M2极化失衡从而影响种植体周围炎的发生和进展,部分药物也可通过Toll样受体/核因子κB信号通路调控巨噬细胞M1/M2极化来治疗相关炎性疾病。②通过分析脂多糖、钛颗粒对种植体周围组织中巨噬细胞M1/M2极化的诱导作用,进一步阐述其调控Toll样受体/核因子κB信号通路诱导巨噬细胞极化的作用机制,以期为种植体周围炎的免疫防治研究提供一些新的思路和策略。

Abstract: BACKGROUND: With the popularization of implant technology, the incidence of peri-implantitis is increasing year by year, but the etiological mechanism is still unclear. Highly plastic macrophages can be polarized into M1 and M2 types under microenvironment stimulation, which play pro-inflammatory and anti-inflammatory effects, respectively, and play an important role in host defense, immune response, and maintenance of internal environment homeostasis in peri-implant tissues. The polarization trend of M1/M2 macrophages is closely related to the balance of foreign body response around implants.
OBJECTIVE: Lipopolysaccharide and titanium particles are important pathogenic factors causing peri-implantitis, in order to further explore their inducible effect on macrophage polarization in peri-implant tissues.
METHODS: The Chinese keywords were “peri-implantitis, macrophage polarization, lipopolysaccharide, titanium particles.” The English keywords were “macrophage polarization, peri-implant inflammation, peri-implantitis, LPS, TLRs, NF-κB.” The CNKI and PubMed databases were searched, and the relevant literature was screened and sorted to analyze the induction effect and related mechanism of lipopolysaccharide and titanium particles on M1/M2 polarization of macrophages in peri-implant tissues.
RESULTS AND CONCLUSION: (1) Lipopolysaccharide and titanium particles may induce macrophage polarization in peri-implant tissues through Toll-like receptor/nuclear factor κB and other related signaling pathways, causing M1/M2 polarization imbalance and thus affecting the occurrence and progression of peri-implantitis. Some drugs can also regulate macrophage M1/M2 polarization through Toll-like receptor/nuclear factor κB signaling pathway to treat related inflammatory diseases. (2) By analyzing the induction effect of lipopolysaccharide and titanium particles on macrophage M1/M2 polarization in peri-implant tissues, the mechanism of their regulation of Toll-like receptor/nuclear factor κB signaling pathway to induce macrophage polarization is further explained, in order to provide some new ideas and strategies for the study of immune prevention and treatment of peri-implantitis.
