Outline of Final Research Achievements |
We evaluated the therapeutic effect of anti-Angionpoietin(ANG) 2 antibody(Ab) with Experimental autoimmune uveoretinitis (EAU) mice. Anti-ANG2 Ab was administered twice at day-1 and day7 after EAU induction. In this study, both clinical score and histological score had no significant difference between anti-ANG2 Ab-treated group and untreated group. However, we elucidated the therapeutic effect of combination therapy with anti-ANG2 Ab and anti-VEGF Ab in Endotoxine induced uveitis (EIU) mouse model. From these results, if EAU mouse is treated with monotherapy with anti-ANG2 Ab, it is necessary to re-consider the amount, timing, and frequency of administration. On the other hand, this combination therapy may have a potential to treat intraocular inflammation.

Academic Significance and Societal Importance of the Research Achievements |
今回のEAUマウスモデルを用いた検討では抗Ang2抗体単独での十分な炎症抑制効果を示すことはできなかった。しかしながらEIUマウスモデルを用いた検討では抗Ang2抗体と抗VEGF抗体と併用することにより炎症抑制効果が得られる可能性を示すことができた。またその要因の一つとしてNF-κBを介した経路が関与していることが考えられた。このようにAng2阻害薬については投与量や投与間隔、そして他の薬剤との組み合わせをさらに検討することでEAUにおいても有意な治療効果が得られる可能性がある。ひいては将来的な臨床応用につながることも期待できる薬剤と考えられた。
