| Outline of Final Research Achievements |
We found that novel pro-inflammatory cells derived from adipose progenitor cells in adipose tissue trigger adipose tissue inflammation. Interestingly, there are cells with similar characteristics in the liver, so we aimed to elucidate the pathogenic mechanism of nonalcoholic steatohepatitis (NASH) originating from these novel inflammatory cells. By analyzing the transcriptome of novel inflammatory cells in the liver by RNA-seq, we were able to find the cytokine candidates involved in the interaction with immune cells.

| Academic Significance and Societal Importance of the Research Achievements |
非アルコール性脂肪肝疾患（NAFLD）は世界で成人の25%が罹患し、一部は肝線維化を伴うNASHとなり、さらにその一部が肝硬変、肝癌へと進行する。NASHは主に脂肪肝と肝臓における炎症を特徴とする病態であるが、その発症機序や心血管疾患や悪性腫瘍等、肝疾患以外による死亡リスクに関しての理解は不十分で、治療標的の同定も進んでいない。肝臓において新たに同定された炎症を惹起する細胞が新たな治療標的としての候補として期待される。
