Outline of Final Research Achievements

In this study, we have demonstrated for the first time that a newly identified liver-derived factor, neuregulin 1, is induced in liver of diabetic mice with increased its protein levels in blood. In diabetic conditions, loss of hepatic neuregulin 1 aggravates glucose tolerance while administration of neuregulin 1 protein ameliorates it. These results strongly suggest that neuregulin 1 serves as a defensive mechanism against type 2 diabetes and could be a novel therapeutic target for type 2 diabetes.

Academic Significance and Societal Importance of the Research Achievements

本研究成果により新たに同定されたニューレグリン1は、肝臓から分泌されるタンパク質として、2型糖尿病の病態を抑制する血糖降下作用を持つ内因性防御機構であることが分かった。このことは、ニューレグリン1を介した臓器間相互作用が2型糖尿病の病態の形成や進展に重要であることを示した新しい発見である。また、ニューレグリン1が、既存の治療薬とは異なる作用点に働きかけることができる2型糖尿病の新しい治療標的になりうることが明らかになった。
