Outline of Final Research Achievements

For in vivo osmo-monitoring, we evaluated our original reporter system which monitors environmental osmolarity via an artificial promotor (on specificity, sensitivity and time course of the reporter). These results suggest that the monitoring system exhibits high specificity to osmotic condition and responsiveness to several hours’ osmotic environment. Although we obtained several mice harboring the reporter gene (transgenic mice), we could not establish a mouse line fulfilling the practical use for osmo-monitoring in vivo because of lack of signal intensity or failure of germline transmission. We still continue to establish the osmo-monitoring mouse line.

Academic Significance and Societal Importance of the Research Achievements

本研究によって、これまで不可能であった細胞スケールの局所浸透圧を実際にモニタリングするための独自の新しい方法論の妥当性の検証ができた。残念ながら実際にOsmonitoringマウス系統の樹立には至らなかったが、本研究で得られた情報とリソースをもとに継続して作成を試みる。これにより、炎症やがん局所の微小環境における実際の浸透圧環境の時空間的な広がりと、それによる免疫細胞制御の機序を明らかにできれば、感染防御やがん免疫の強化、過剰炎症の抑制を浸透圧制御の観点からコントロールできる薬剤の開発やその知的財産の取得にもつながる可能性がある。
