KeywordsIgG4関連疾患 / TRPチャネル
Outline of Research at the Start

本研究では、以下の点について明らかにする。
1.IgG4関連疾患患者およびLat Y136F knock-in miceの病変組織および末梢血リンパ球における各種TRPチャネルの発現を検討する。
2.発現が亢進しているTRPチャネルについてLat Y136F knock-in miceの血球または組織を用いて、パッチクランプ法を用いた電気生理学的評価を行う。4,6,8週齢の検体を用いることで経時的な評価を行う。
3.TRPチャネル阻害薬による病変抑制効果について検討する。
4.TRPC3チャネルの特異的阻害剤であるピラゾール化合物をLat Y136F knock-in miceに投与し、TRPC3チャネル抑制を行い、線維化抑制効果の有無について検討する。

Outline of Final Research Achievements

We analyzed the involvement of TRP channels in IgG4-related disease. Using tissues from the kidney, salivary gland, and lung of Lat Y136F knock-in mice, a model of IgG4-related disease, we investigated the expression of TRPM2, which has been reported to be involved in inflammation, and TRPC3, which has been associated with fibrosis, by immunohistochemistry. TRPM2 was expressed in the inflammatory cell infiltration sites of the kidney, salivary gland, and lung. Similarly, TRPC3 expression was upregulated in the regions of inflammatory cell infiltration in all three organs. These findings suggest that TRP channels may be involved in the processes of inflammation and fibrosis in IgG4-related disease.

Academic Significance and Societal Importance of the Research Achievements

IgG4関連疾患の治療における問題点として、ステロイド以外の代替薬が確立してないこと、再燃が多く完治が困難であること、線維化による不可逆的な臓器障害を生じうることが挙げられる。本研究では、炎症や線維化に関与するイオンチャネルである、TRPM2およびTRPC3がIgG4関連疾患モデルマウスの病変において発現を認めたことから、これらのチャネルがIgG4関連疾患の病態に関与していることが示唆された。本研究では発現のみの解析であったが、将来的に新規治療のターゲットとなり得る分子の基礎データの一つとなり得たと考えられる。
