Research Abstract

本研究目的は、福山型筋ジストロフィー(FCMD)の発症機序を理解し、治療戦略を構築することである。FCMDでは、ジストログリカンという糖タンパク質に糖鎖修飾異常が生じており、これが発症に関与すると考えられている。本研究では、独自に作出したFCMDモデルマウスの病態・生化学解析を行った。その結果、糖鎖異常を完全に回復させる必要はなく、部分的な回復のみで病態の軽減・抑制につながる、という新概念を提唱するに至った。更に、糖鎖異常の解消手段として、FCMD原因遺伝子のフクチン、あるいは、糖鎖増強作用を持つLARGEを対象とした遺伝子治療が効果的であることも示された。
