牙周炎是一种常见的炎性骨丧失类型,也是全身性疾病的一个风险因素。牙周炎的发病机制涉及炎症失调,这是治疗牙周炎的新治疗策略的一个靶点。在确定患者样本中无细胞DNA(cfDNA)水平与牙周炎的相关性之后,我们检验了cfDNA清除方法将有益于牙周炎治疗这一假设。我们通过用阳离子聚酰胺 - 胺树枝状大分子(PAMAM - G3)包裹硒掺杂羟基磷灰石纳米粒子(SeHANs),即G3@SeHANs,创建了一种针对牙周炎的纳米颗粒cfDNA清除剂,并将G3@SeHANs的活性与可溶性PAMAM - G3聚合物的活性进行了比较。G3@SeHANs和PAMAM - G3在体外都通过清除cfDNA抑制与牙周炎相关的促炎反应,并在结扎诱导的牙周炎小鼠模型中减轻炎性骨丧失。G3@SeHANs还在牙周炎环境中调节单核吞噬细胞系统,促进M2型巨噬细胞表型多于M1型。G3@SeHANs在体内减少促炎反应和牙槽骨丧失方面显示出比PAMAM - G3更好的治疗效果。我们的研究结果证明了cfDNA在牙周炎中的重要性以及使用基于羟基磷灰石的纳米颗粒cfDNA清除剂改善牙周炎的潜力。 牙周炎是一种常见的炎性骨丧失类型,无细胞DNA(cfDNA)可能是加剧牙周组织破坏的一个主要来源。在这里,作者表明通过使用纳米颗粒cfDNA清除剂,cfDNA清除方法能够改善牙周炎。
Periodontitis is a common type of inflammatory bone loss and a risk factor for systemic diseases. The pathogenesis of periodontitis involves inflammatory dysregulation, which represents a target for new therapeutic strategies to treat periodontitis. After establishing the correlation of cell-free DNA (cfDNA) level with periodontitis in patient samples, we test the hypothesis that the cfDNA-scavenging approach will benefit periodontitis treatment. We create a nanoparticulate cfDNA scavenger specific for periodontitis by coating selenium-doped hydroxyapatite nanoparticles (SeHANs) with cationic polyamidoamine dendrimers (PAMAM-G3), namely G3@SeHANs, and compare the activities of G3@SeHANs with those of soluble PAMAM-G3 polymer. Both G3@SeHANs and PAMAM-G3 inhibit periodontitis-related proinflammation in vitro by scavenging cfDNA and alleviate inflammatory bone loss in a mouse model of ligature-induced periodontitis. G3@SeHANs also regulate the mononuclear phagocyte system in a periodontitis environment, promoting the M2 over the M1 macrophage phenotype. G3@SeHANs show greater therapeutic effects than PAMAM-G3 in reducing proinflammation and alveolar bone loss in vivo. Our findings demonstrate the importance of cfDNA in periodontitis and the potential for using hydroxyapatite-based nanoparticulate cfDNA scavengers to ameliorate periodontitis.
