| Outline of Final Research Achievements |
In persistent hyperplastic primary vitreous (PHPV), remaining hyaloid vessels often adhere to retinal surfaces. We previously found that in semaphorin 3E (Sema3E) knockout mice, hyaloid vessels ectopically invaded into retinas, leading to the formation of retinal folds (Fukushima et al. J Clin Invest 2011). In this research project, Sema3E derived from retinal ganglion cells bound to PlexinD1 on the endothelial cell surfaces of hyaloid vessels and activated a small GTPase RhoJ, thereby preventing ectopic hyaloid invasion into the retina.
