Outline of Research at the Start

アンジオポエチン(angiopoietin:Ang)をターゲットにした治療法は、悪性腫瘍、炎症性疾患、血管透過性亢進をきたす疾患において注目されている。網膜領域では糖尿病網膜症への関与の報告はあるが、網膜静脈閉塞症(retinal vein occlusion: RVO)への関与の報告はない。本研究の成果はRVOにおける血管透過性亢進や炎症を制御する可能性を秘めており、黄斑浮腫を伴うその他の疾患やぶどう膜炎などの炎症性疾患においても新たな知見をもたらし、新規治療薬開発の足がかりともなり得る可能性を秘めている。

Outline of Final Research Achievements

Intravitreal injection of anti-vascular endothelial growth factor (VEGF) has been benefical in improving the visual outcomes in patients with a retinal vein occlusion (RVO) with macular edema. However, there are still refractory cases or most patients need multiple injections of anti-VEGF agents. We focused on angiopoietin: Ang) as anew target in the treatment of RVO with macular edema. Ang is involved in RVO, suggesting that its control may be necessary.

Academic Significance and Societal Importance of the Research Achievements

網膜静脈閉塞症 (retinal vein occlusion: RVO) の視力低下の主因は黄斑浮腫である。その黄斑浮腫に対する血管内皮増殖因子 (vascular endothelial growth factor: VEGF) 阻害療法は一定の効果をあげているが、治療抵抗例・再発例、頻回の治療が必要であるなど、課題が多い。今回我々は、マウスで実験的RVOモデルを作成し、RVOの病態解明を行った。RVOにおいてアンジオポエチン(angiopoietin: Ang)が関与しており、その制御が必要である可能性が示唆された。
