ABSTRACT Periodontitis is a male-dominant, heterogeneous, inflammatory disease of the bone and tissues supporting the tooth. It is one of the most prevalent non-communicable chronic diseases, with ~50% prevalence in the American population. Currently, there are no adjuvant therapies available to treat the 20-25% of “hyper-inflammatory” patients that progress to tooth loss despite appropriate standard of care. In support of this current proposal, inflammasome modulation has been proposed to treat several inflammatory diseases. Inflammasome is required for processing of pro-interleukin (IL)-1, pro-IL-18, and Gasdermin-D into their mature, functional forms. Despite the common knowledge that IL-1 is sexually dimorphic and a marker for periodontal inflammation, its role as a direct driver of disease development in both females and males is not clear. We find that inflammasome activation has both a protective and destructive effect on periodontal tissue that is differentially regulated between the sexes. Our data suggest the existence of sex-based distinct pathways of periodontal bone loss. This study will expand our current knowledge on the role of inflammasomes in periodontal inflammation and tissue destruction in females and males. We propose to build upon our findings to develop the below aims: Aim 1: Define the impact of biological sex in inflammasome activation during periodontal disease development and progression. Aim 2: Define the relationship between inflammasomes and periodontal tissue repair. Aim 3: To use a new strategy to target inflammasomes for preventing murine periodontitis. 1

摘要 牙周炎是一种以男性为主的异质性骨和组织炎症性疾病 支撑牙齿。它是最流行的非传染性慢性病之一， 在美国人群中的患病率约为50%。目前，没有可用的辅助疗法 治疗20-25%的“高度炎症”患者， 适当的护理标准。为了支持这一当前的提议，炎性小体调节具有 已被提议用于治疗几种炎症性疾病。加工需要炎性小体 IL-18和Gasdermin-D转化为成熟的功能形式。尽管 IL-1 β具有性别二型性，是牙周炎的标志物， 炎症，其作为女性和男性疾病发展的直接驱动因素的作用不是 清楚我们发现，炎性小体激活对细胞增殖既有保护作用，也有破坏作用。 牙周组织，这是差异调节的性别之间。我们的数据表明， 存在基于性别的牙周骨丢失的不同途径。这项研究将扩大我们的 炎性小体在牙周炎症和组织中作用的研究现状 在女性和男性的毁灭。我们建议根据我们的调查结果制定以下内容 目的：目的1：明确生物性别对牙周炎性小体激活的影响。 疾病的发展和进展。目的2：确定炎性小体之间的关系 和牙周组织修复。目的3：使用一种新的策略靶向炎性小体， 预防鼠牙周炎。 1
