Vascular endothelial growth factor antagonist therapy for retinopathy of prematurity.
نویسنده
چکیده
In this article, the growing problem of retinopathy of prematurity (ROP) worldwide, treatments for severe ROP including standard-of-care laser treatment, and the need for new treatments are discussed. Also discussed are the reasons to consider inhibiting the vascular endothelial growth factor (VEGF) signaling pathway in severe ROP and the concerns about broad VEGF inhibition. Finally, the potential role of VEGF in ROP based on studies in animal models of oxygen-induced retinopathy, the effects of anti-VEGF based on basic research data, and the clinical relevance of these data are covered.

Retinal neovascularization is prevented by blockade of the renin-angiotensin system.
Both angiotensin II and vascular endothelial growth factor are angiogenic agents that have recently been implicated in the pathogenesis of proliferative diabetic retinopathy. In this study, retinal neovascularization was examined in a model of retinopathy of prematurity with the use of neonatal transgenic (mRen-2)27 rats, which overexpress renin in tissues, and Sprague-Dawley rats. Blockers of ...
متن کاملRoles of vascular endothelial growth factor and astrocyte degeneration in the genesis of retinopathy of prematurity.
PURPOSE To assess the role of vascular endothelial growth factor (VEGF) in the feline model of retinopathy of prematurity (ROP). METHODS Retinopathy of prematurity was induced in neonatal cats by raising them in an oxygen-enriched (70% to 80%) atmosphere for 4 days to suppress vessel formation and then returning them to room air for 3 to 27 days. In situ hybridization was used to detect the e...
متن کاملInsulin-like growth factor-1 and anti-vascular endothelial growth factor in retinopathy of prematurity: has the time come?
Treatment of retinopathy of prematurity (ROP) is currently evolving. Novel therapeutic options are emerging that have the potential to complement existing therapies and improve treatment outcomes. However, any new therapeutic option must be thoroughly evaluated before existing (and successful) treatment paradigms can be amended. This is particularly so when switching from locally effective ther...
متن کاملLow IGF-I suppresses VEGF-survival signaling in retinal endothelial cells: direct correlation with clinical retinopathy of prematurity.
Retinopathy of prematurity is a blinding disease, initiated by lack of retinal vascular growth after premature birth. We show that lack of insulin-like growth factor I (IGF-I) in knockout mice prevents normal retinal vascular growth, despite the presence of vascular endothelial growth factor, important to vessel development. In vitro, low levels of IGF-I prevent vascular endothelial growth fact...
