角膜血管新生における病態変化の模式図 (IMAGE) Kumamoto University Caption DSCR-1 はNFAT 異常活性化や酸化ストレスを防ぐブレーキ役であるが、これが働かないと高コレステロール血症では LDL の酸化 (OxLDL) が進み、内皮での SDF-1/CXCR4 シグナルが活性化し、マクロファージでの VEGF 産生が進む。これらの活性化により、通常は無血管で透明な角膜に血管が侵入し、混濁が生じる。 Credit Professor Takashi Minami Usage Restrictions <p>Fig. 5(G) of <a href="https://www.ahajournals.org/doi/10.1161/ATVBAHA.120.315003">Muramatsu, M. et al.
