Outline of Final Research Achievements

We investigated the effects of inhibition of eukaryotic translation initiation factor 2 alpha (eIF2α) dephosphorylation on periodontal disease. The results showed that salubrinal and guanabenz (inhibitors of elF2α dephosphorylation) alleviated periodontal disease by suppressing alveolar bone resorption and attachment loss in periodontal disease models.

Academic Significance and Societal Importance of the Research Achievements

本研究により、elF2α脱リン酸化阻害剤(salubrinal,guanabenz)による歯周病予防効果が示された。これは、elF2α脱リン酸化阻害剤(salubrinal,guanabenz)が歯周病の発生メカニズムを予防する新たな歯周病予防薬となる可能性を示しており、炎症を引き起こす物質の抑制が主である従来の歯周病予防に対し、歯根膜幹細胞や免疫細胞の反応を直接阻害することにより歯周病を予防できる可能性がある。
