Outline of Research at the Start

腸の炎症はヒトが最も頻繁に経験する炎症反応の一つである。腸は外界とつながる臓器であり、常に様々な刺激にさらされ炎症反応が活発に生じる。また原因が解明されていない炎症性腸疾患も近年増加の一途をたどっている。本研究では、血管研究を通じて、腸の炎症制御機構を解明する。特に大腸と小腸における部位特異的炎症制御機構の解明を目的とする。血管を取り巻く微小環境により炎症が制御されている可能性が考えられ、血管に焦点を当てた解析を通じて腸管の炎症制御を規定する分子機序を解明できる可能性がある。本研究が実現すると、腸の炎症制御機構に関する概念を大きく転換でき、腸炎の新たな治療法の開発につながる可能性がある。

Outline of Final Research Achievements

In this study, we aimed to elucidate the site-specific mechanisms of inflammation control in the large and small intestines through vascular research. To date, we have created endothelial specific knockout mouse model in which the blood vessels are not maintained. Preliminary experiments have also revealed that the mechanisms controlling inflammation may differ between the small intestine and the large intestine. Using immunostaining, FACS analysis, gene expression analysis, and endothelial cell culture experiments, we analyzed the vascular structure of the intestines, the distribution of blood cells, and differences in gene expression. As a result, several genes were expressed differently, and we focused on a fraction of cytokines and immune cells to analyze the relationship between vascular maintenance mechanisms and inflammation control mechanisms. Although we could not identify the key molecule in inflammation control, we are continuing to analyze other candidates.

Academic Significance and Societal Importance of the Research Achievements

腸炎はヒトが生活する中で、最も頻繁に経験する炎症反応の一つである。また、原因不明の炎症性腸疾患も増加の一途をたどっている。腸で生じる炎症は、腸管の部位特異性を認めることがあるが、なぜこのような部位特異性を認めるか不明である。本研究では、血管研究を通じて、大腸と小腸における部位特異的炎症制御機構を解明に挑戦した。今回、腸管の血管構造、免疫細胞の分布を明らかにして、血管維持機構との関係を、培養実験を通じて解析した。炎症制御に関与すると考えられる候補因子を複数同定しており、今後これらを制御することで、腸管の炎症制御につながることが期待できる。
