Outline of Research at the Start

細胞はエクソソームと呼ばれる直径30-100 nmの小胞を分泌することが知られている。そこに内包されるタンパク質やマイクロRNAがアレルギー疾患の発症に関与することが示唆されている。そこで本研究計画では、アレルギーの責任細胞であるマスト細胞から遊離されるエクソソーム中マイクロRNAが、どのような機序で2型自然リンパ球からのIL5産生を増強し、喘息の増悪化に関与するかを明らかにする。

Outline of Final Research Achievements

The present study demonstrated that miR103a-3p was highly expressed in exosomes released by mast cells. These exosomes reduced the expression levels of PRMT5 in group 2 innate lymphoid cells and skewed methylated GATA3 to demethylated GATA3 in ILC2, leading to enhancement of IL-5 produciton, contributing to eosinophilia, from ILC2. Together, these might suggest that miR103a-3p in exosoomes from mast cells contributed to the exacerbation of eosinophil-mediated allergic inflammation.

Academic Significance and Societal Importance of the Research Achievements

エクソソームに内包されるタンパク質やmiRNAは細胞間相互作用に重要な役割を果たすことがよく知られているが, マスト細胞が遊離するエクソソーム中のmiRNAの役割に関して, 初めて明らかにした. その結果, アトピー性皮膚炎などのアレルギー疾患を遷延化させるメカニズムの一端を明らかにできた.
