Outline of Final Research Achievements

We developed a method of video-rate bioluminescence imaging to directly detect degranulation from a single mast cell by measuring luminescence activity derived from the enzymatic reaction between Gaussia luciferase (GLase) and its substrate coelenterazine. Bioluminescence imaging analysis of mast cells (MCs) expressing NPY-GLase showed that the luminescence signals of the secreted NPY-GLase were repeatedly detected after the addition of an antigen.
In addition, we found that an antigen-induced increase in intracellular Ca2+ concentration was suppressed slightly in cells on hydrogel-coated dishes compared with those on non-coated dishes, whereas their subsequent degranulation was largely inhibited in cells adherent to the hydrogel. Vinculin was distributed in a dot-like manner at the bottom of resting cells on non-coated dishes but not on hydrogel-coated dishes. Moreover, microtubule reorganization and acetylation were also suppressed in activated MCs adherent to the hydrogel.

Academic Significance and Societal Importance of the Research Achievements

神経-免疫シナプスの分子機構の解析に必要な基盤技術を確立することができた。生体内の様々な組織に分布しているマスト細胞の多くは、神経細胞の近傍に存在していることが知られている。また、両細胞は組織ごとに異なる細胞外マトリックス(ECM)に接着して生存している。また、ECMの性質は疾患の進行に伴う組織の繊維化や、マスト細胞の分泌するケミカルメディエーターによって変化することが知られている。今後、本研究の成果を活用して、神経細胞とマスト細胞の相互作用の研究を進めていくことにより、新たな視点から抗原非依存的な炎症反応誘導の分子機構を明らかにしていくことが可能であると考えている。
