Outline of Final Research Achievements |
Lipopolysaccharide (LPS) is well known to activate Toll-like receptor 4 (TLR4) signaling and induce cardiac dysfunctions. The aim of the present study was to investigate the effects of LPS derived from Porphylomonas gingivalis (PG-LPS) on cardiac function in mice with or without an inhibitor of TLR4 signaling (TAK-242) for 4 weeks. Mice were divided into 4 groups:1) Control 2) PG-LPS-treated group, 3) TAK-242-treated group, and 4) PG LPS+TAK-treated groups. We first examined cardiac function by echocardiography and found that cardiac function was significantly decreased by the treatment of PG-LPS, but TAK-242 protected the dysfunction. Cardiac fibrosis (Masson-trichrome staining) and myocyte apoptosis (TUNEL staining) were significantly increased by the treatment of PG-LPS, but TAK-242 blocked these changes. These data suggest that chronic PG-LPS infusion might play an important role for the development of cardiac dysfunction via activation of TLR4 signaling.

Academic Significance and Societal Importance of the Research Achievements |
歯周病と心疾患の関連性については、疫学的に関連があるという報告は多いが、一方で最近米国心臓病協会(AHA)より、因果関係について断定できる確証はないことが報告された (Lockhart PB et al. Circulation 2021)。本研究より歯周病の罹患を予防することは、健康寿命の延伸に重要であることが理解されれば、欧米諸国に比較して低い我国の歯科検診受診率は向上し(スウェーデン90%,アメリカ 80%,イギリス 70%, 日本6%)、日本歯科医師会と厚生労働省が推進する8020運動(80歳以上でも自分の歯を20本以上保つことで豊かな人生を)の達成率増加にも貢献すると期待される。
