Outline of Final Research Achievements

proliferative vitreoretinopathy is very severe retinal disease. there is high risk of blindness. Vitrectomy is the only method of the treatment for vitreoretinopathy. The molecular targeted therapy is long-awaited as the adjuvant. Anti-fibronectin ED-A antibody inhibited TGF-β2-induced extracellular matrix production in the retinal pigment epithelial cells.

Academic Significance and Societal Importance of the Research Achievements

増殖硝子体網膜症は裂孔原性網膜剥離術後の重篤な合併症であり、線維性細胞増殖が網膜上、網膜下および硝子体腔に生じ収縮で剥離網膜が牽引固定される病態である。病態形成の詳細な分子メカニズムは完全に解明されておらず現状では有効な薬物治療もない。外科的に硝子体手術でこの増殖膜を除去する以外に治療法がなく、際限なく増殖を繰り返す症例もあり、増殖を抑制する何らかの内科的な補助治療の確立が望まれている。病的な組織にしか発現のない抗fibronectin ED-A抗体がある程度の効果をもたらしたことは今後の治療薬開発に期待が持てる。
