当研究分野は2018年4月より発足しました。細胞小器官の研究は、それぞれの細胞小器官が持つ個性的な内部空間(ルーメン)の機能を解き明かすことを中心に進んできましたが、細胞小器官を形作っている膜そのものにも重要な機能が潜んでいると考え研究をすすめています。

最近の研究について

・自然免疫分子STINGの活性化がゴルジ体で起こること、そのメカニズムとしてゴルジ体膜で起こるSTINGのパルミトイル化脂質修飾が必須であることを明らかにしました(Mukai et al., Nat Commun 2016)。STINGは老化や生活習慣病による炎症、抗腫瘍免疫など幅広い生命現象に関与しており、STINGの活性化・不活性化の分子機構を理解することは、純粋なサイエンスとしての興味に加えて、人類の健康に大きく貢献するものと考えています。
・細胞小器官に固有に存在するリン脂質を利用した、細胞小器官に局在するタンパク質の同定法を開発しました(Matsudaira et al., Nat Commun 2017)。今後、細胞小器官膜の機能解明に多いに貢献することが期待される新手法です。
 

メッセージ

誰も知らなかった真実を発見し、そのことによって、今まで不可解だった様々な現象がいきなり矛盾なく説明することができるようになった時の喜びこそが、サイエンスの醍醐味だと思います。是非、皆さんとそのような経験を味わっていきたいと思っています。
