牙周病是一种全球性的细菌感染性慢性疾病,且发病率随着年龄增长而增加。

本研究主要探究牙周炎中的宿主适应性免疫应答。虽然牙周炎实验模型和人类患者对特定的口腔细菌表现出抗原特异性,但我们对于年龄如何影响牙周炎的理解有限:(i)机体对疾病表现前数十年定植口腔的细菌的适应性免疫反应,和(ii)疾病恶化期间与细菌生态学中出现的病原体相互作用应答的大小和特异性如何。

在21-74岁的个体群体中测量了一组致病和共生口腔细菌的血清抗体水平,并基于牙周组织的临床状态、吸烟和性别进行分层。

结果显示,在与年龄相关的健康、牙龈炎或牙周炎组间临床参数没有明显的差异。在每个临床类别中,不同年龄组的口腔病原体和共生物抗体相似,牙周炎患者中未观察到年龄相关性。

结果表明,对长期定居于口腔的口腔细菌的适应性免疫应答一般不受年龄影响,但显然与疾病严重程度有关。
