Research Abstract

同種造血幹細胞移植において最も大きな合併症は移植片対宿主病(GVHD)である。急性GVHDの本質はアロ抗原特異的な免疫反応であるが、その病態は様々な炎症反応により修飾されており、必ずしも詳細は明らかになっていない。その診断においては客観的な特異マーカーがなく、移植後早期の合併症との鑑別診断も必ずしも容易でない。また予防や治療においても副腎皮質ホルモン剤などの非特異的な免疫抑制剤が主体であり、GVHDに対する特異的な治療法の開発が望まれている。本研究は申請者らが同定したDNAM-1(CD226)を分子標的としたGVHDに対する新しい診断と免疫療法の基盤開発を目的とした。
はじめに、致死量の放射線照射したマウスに骨髄移植を行ないGVHDを誘導したモデルマウスを作製した。DNAM-1が急性GVHDの発症や病態に関与するか否かを明らかにするために、DNAM-1遺伝子欠損マウスを樹立した。これを用いて、DNAM-1遺伝子欠損マウスをドナー、またはレシピエントとした際のGVHDの発症の有無と程度を観察した。その結果、DNAM-1遺伝子欠損マウスをドナーとした際に、GVHDの発症の程度が減弱している傾向が認められた。そこで、抗体を用いた分子標的療法の可能性を探るために、DNAM-1に対する中和抗体(TX42)を作製した。今後、これらを用いてGVHDの発症機構におけるDNAM-1の役割を詳細に解析するとともに、分子標的療法へ向けた基盤的知見を集積していく。
