Outline of Final Research Achievements |
We have developed a technology to obtain information on "angle" in biological phenomena by measuring the "orientation" of molecules using the properties of polarization and anisotropy of fluorescence. In particular, we established a method to detect the changes in the angle (curvature) of cell membranes by translating it to changes in fluorescence intensity corresponding to alteration of the molecular orientation. With these advantages, the curvature of the plasma membrane and its change, which had been visible only observable with electron microscopy, can be optically observed at a high time resolution (second level), making possible to visualize cell membrane deformation in the very early stage of endocytosis.

Academic Significance and Societal Importance of the Research Achievements |
本研究成果は、エンドサイトーシスの超初期過程の細胞膜変形の分子メカニズムを解明に資する技術革新といえる。細胞膜の変形は100 nm程度以下の領域で生じる現象で、現存する超解像顕微鏡でも時間分解能を伴うダイナミクスの観察は不可能であり、「向き」に着目することで従来技術の限界を超える観察が可能となった。今後は、本研究成果を基盤に、「角度」と「向き」に着目した新しい生物学の新領域の開拓を目指したい。
