Outline of Research at the Start

「薬剤関連顎骨壊死(MRONJ)」の病態は不明な点が多く病態発生メカニズムの解明や治療法の開発が急務である.近年,MRONJの実験動物モデル(マウス)が開発され,生体内での骨芽細胞,破骨細胞,間葉系幹細胞の挙動を解析することが可能となった.一方,MRONJモデルマウスの抜歯窩において,大腸菌由来ヒト遺伝子組換え骨形成タンパク質(rhBMP)-2が強力な骨形成能を有していることが予備的検討により明らかになった.そこで,マウスMRONJモデルの抜歯窩に対するrhBMP-2局所投与の効果とその用量の検討後,MRONJの病態やrhBMP-2の効果機序の解明をマウスで,非臨床POC取得を目指したブタMRONJモデルにおけるrhBMP-2の応用を行う.

Outline of Final Research Achievements

The pathogenesis of medication - related osteonecrosis of the jaws (MRONJ) remains largely unknown. Therefore, it is essential to elucidate the pathogenesis of MRONJ and to develop a treatment for this disease. We hypothesized that BMP-2, which has strong osteogenic potential, might be useful in the treatment of MRONJ. In fact, a mouse MRONJ model was created and rhBMP-2 was administered into the extraction socket.  The results showed that bone formation in the extraction socket was suppressed in the non-transplanted group, whereas bone formation was significantly enhanced by rhBMP-2 transplantation. These results suggest that BMP-2 may be a new treatment for MRONJ.

Academic Significance and Societal Importance of the Research Achievements

近年,骨吸収抑制薬の使用による大腿骨非定型骨折や外耳道骨壊死が報告され,骨吸収抑制薬は顎骨だけではなく全身の骨への影響が示唆されている.本研究で得られるMRONJ発症の理解および治療法の開発は,顎骨以外の全身の骨組織への影響の理解にもつながることは言うまでもなく,骨粗鬆症や大理石骨病などの全身性骨代謝性疾患の治療に十分応用が可能である.したがって,本申請研究による成果は歯科分野に留まることなく,医療分野全体へ広く貢献することは明らかである.
