Outline of Final Research Achievements

We have identified that TSAd is a downstream molecule of the VEGF signaling and proved that it is essential for VEGF-induced angiogenesis. In this study, we analyzed the differences in the retinopathy of prematurity severity in a retinopathy of prematurity mouse model using TSAd knockout mice. TSAd knockout mice developed milder retinopathy of prematurity than wild-type littermates. Therefore, TSAd has potential as a therapeutic target for retinopathy of prematurity.

Academic Significance and Societal Importance of the Research Achievements

抗VEGF薬の眼内注射による治療は、従来のレーザー治療のように網膜を破壊することなく、この異常な血管新生を抑制し、ROPの進行を防ぐ。しかし、VEGFは脳などの中枢神経系の血管の発達にも重要であり、VEGFを直接阻害する治療は、その作用の多様性から、発達途上の小児期では副作用を慎重に考慮する必要がある。TSAdは、VEGFが病的に発現している環境下でより機能する分子の可能性があり、この分子を標的にする治療法は、抗VEGF薬に比し、効果が限定され、より副作用の少ない治療法として期待できる。
