| Outline of Final Research Achievements |
In this study, we will clarify the distribution and ratio of lymphocytes, macrophages and dendritic cells in human dental pulp, create rat caries model and evaluate dental pulp dendritic cell subsets, function evaluation and acquired immune system in caries. The purpose was to clarify the involvement. Until now, there have been reports of many branched cells at the forefront of mouse dental pulp and that they are dendritic cells, but we have used these forefront of branched cells as markers for macrophages The positive Iba1 indicates that it is likely to be a macrophage, suggesting that this macrophage plays an important role in the dental pulp immune response.

| Academic Significance and Societal Importance of the Research Achievements |
我々の研究成果から、象牙芽細胞層最前線に存在するIba1陽性細胞はマクロファージと考えられ、う蝕などの歯髄における免疫応答に重要な役割を果たしていると考えられた。う蝕における獲得免疫系の関与を研究した報告はなく、今後歯髄の免疫機構の解明が進めば、う蝕治療において生体防御機構を利用した新しい治療法の確立が可能となると考えられる。
