Outline of Research at the Start

GDF11およびmyostatinはTGF-bスーパーファミリーに属するシグナル調節因子である.GDF11は発生初期における様々な器官形成に関与することが知られているが,近年はparabiosisによる老齢マウスのGDF11レベルが改善することでシナプス可塑性,認知機能の改善,骨格筋の再生,心肥大の抑制が報告されたことで注目されている.またMyostatinは骨格筋の強い負の制御因子として知られている.一方,顎口腔領域では様々な加齢変化による生理機能の低下が見られる.本研究では免疫組織化学的手法を用いてGDF11とmyostatinの顎口腔領域での発現分布を解析し,その機能を検討する.

Outline of Final Research Achievements

GDF11 and myostatin are members of the transforming growth factor β (TGF-β) superfamily. Although they play pivotal roles during development, little information is available for the expression in the adult central nervous system. This research revealed follistatin and BMP9 expression in the adult rat central nervous system and suggested the idea that they play important roles in the adult neurogenesis.

Academic Significance and Societal Importance of the Research Achievements

本研究ではTGF-βスーパーファミリーに属するfollistatinとBMP9の成体ラット中枢神経系での発現分布を明らかにし、成体神経新生への可能性が示唆された。これまでこれらの因子は発生期における重要な機能のみが明らかになっていたが、成体における分子生物学的な機能が明らかになることで認知機能の低下を代表とする加齢変化に対する創薬につながると考えられる。
