Outline of Final Research Achievements

This study has revealed that near infrared (NIR) fluorescence imaging with single-walled carbon nanotubes (CNTs) can selectively image brown adipose tissue (BAT) and monitor the BAT changes in mice induced by the external stimulation when the surfaces of CNTs are properly coated. Furthermore, it has been shown that the NIR fluorescence microscopy enables the observation of CNT distribution in cellular levels, revealing that the BAT vascular permeability is enhanced under fasting in mice. Gene analysis indicated that protease was upregulated under the fasting, which suggested that basal membranes of capillary/arteriolar walls were degenerated as demonstrated by the disarranged or broken collagen bands in the extracellular matrix.

Academic Significance and Societal Importance of the Research Achievements

脂肪を燃焼させる褐色脂肪組織(BAT)は、肥満や糖尿病などのメタボリックシンドロームのための新規予防・治療法開発の標的組織として近年注目されている。これまでBATに対しては、簡便な可視化手段がないという問題があったが、本研究では、近赤外(NIR)蛍光造影剤として知られている単層カーボンナノチューブ(CNT)がその表面被覆を制御することで優れたBAT選択的な蛍光造影剤になることを明らかにした。また、NIR蛍光顕微鏡を用いたCNT分布の細胞レベルでの観察により、未知なBAT機能を明らかにできた。こうした成果は、CNTを用いたBAT造影がBAT研究の発展に寄与することを示唆している。
