Outline of Research at the Start

生体各所に存在する組織マクロファージは局在する組織に応じて特異的な機能・役割を担う『組織特異性』を有する。本研究では、腎臓、精巣、脂肪組織、腹腔のそれぞれの組織マクロファージで特異的に発現することを同定した6つの転写因子に着目して解析を行う。そしてそれら転写因子が、マクロファージの組織特異的な分化や活性化を制御する『マスター転写因子』として機能する可能性について検討する。

Outline of Final Research Achievements

Tissue-resident macrophages are a highly heterogeneous population performing specialized functions that are essential for the maintenance of tissue homeostasis. In this study, we focused on the transcription factors that are uniquely expressed in specific tissue-resident macrophage subsets, and determined whether these transcription factors function as master regulators controlling tissue-specific functions of macrophages. We found that the expression of some of these transcription factors exhibits variation among macrophages present in the same tissue environments. Additionally, we observed the fluctuation of the expression of the transcription factors results in the difference in the global gene expression pattern between tissue macrophages.

Academic Significance and Societal Importance of the Research Achievements

癌、炎症性腸疾患、リウマチ、神経変性疾患、生活習慣病、肺胞蛋白症、大理石骨病などの多岐にわたる疾患において、マクロファージの機能異常がそれら疾患の発症・増悪化に密接に関与することが理解されつつある。本研究は、マクロファージの組織機能を包括的に解析するとともに、それら機能の異常が種々の疾患を引き起こす原因究明に貢献する可能性が考えられる。
