Outline of Research at the Start

エクソソームを模倣したナノ粒子は生体内の微粒子の体内動態解明や創薬研究へ応用できる。また、ナノ粒子の粒径・粒子内外の搭載分子・粒子の力学特性を自在にカスタマイズして設計する手法を確立することで、ナノ粒子を介した分子送達過程を制御することができる。本研究では、ナノ粒子の粒径、粒子内部および表面への分子搭載を自在にカスタマイズできるマイクロ流体デバイスを開発する。

Outline of Final Research Achievements

Exosomes are nano-meter sized extracellular vesicles mainly composed of natural lipids and they mediate complicated intercellular communication in our bodies. They are expected to provide fundamental biological insights and designs of novel nanomedicines. On exosomes surface, there are various biological molecules such as proteins, and inside exosome, there are also biological molecules such as nucleic acids. Referring to recent research relating exsomes, not only biological molecules such as integrins but also their physical characteristics such as size and stiffness are considered as key factors in their unique behaviors in our bodies. In terms of designing of effective nanocarriers, physical characteristics of nanoparticles such as size and stiffness are also important design parameters to achieve desired drug delivery.
In this study, microfluidic methods are demonstrated to produce exosome inspired nanoparticles based on natural lipids with desired size and stiffness.

Academic Significance and Societal Importance of the Research Achievements

本研究成果により、所望の物理特性をもつ多種多様のエクソソーム模倣粒子の調製が可能になる。これにより、従来の人工合成脂質を主成分とする脂質ナノ粒子よりも実際のエクソソームに近い条件で、粒子としての特性(粒子物性)が体内動態へ与える影響を粒子物性を基軸に評価することができるようになる。本研究成果による人工エクソソームの作製手法および、作製粒子によって得られた基礎的知見は、エクソソームが持つ高い生体適合性や選択的蓄積特性をもつような新規ナノ医薬品の設計・作製に貢献し得ると考える。
