The present invention describes methods for inhibiting angiogenesis in tissues using vitronectin .alpha.v.beta.5 antagonists. The .alpha.v.beta.5-mediated angiogenesis is correlated with exposure to cytokines including vascular endothelial growth factor, transforming growth factor-.alpha. and epidermal growth factor. Inhibition of .alpha.v.beta.5-mediated angiogenesis is particularly preferred in vascular endothelial ocular neovascular diseases, in tumor growth and in inflammatory conditions, using therapeutic compositions containing .alpha.v.beta.5 antagonists.

La présente invention se rapporte à des procédés permettant d'inhiber l'angiogenèse dans des tissus au moyen d'antagonistes dirigés contre le récepteur .alpha.¿v?.beta.¿5? de la vitronectine. L'angiogenèse liée à la présence de .alpha.¿v?.beta.¿5? est corrélée à l'exposition à des cytokines comportant le facteur de croissance de l'endothélium vasculaire, le facteur de croissance transformant .alpha. et le facteur de croissance épidermique. L'inhibition de l'angiogenèse liée à la présence de .alpha.¿v?.beta.¿5?, qui est obtenue au moyen de compositions thérapeutiques contenant des antagonistes dirigés contre le .alpha.¿v?.beta.¿5?, est particulièrement utile s'agissant des troubles oculaires néovasculaires de l'endothélium vasculaire, de la croissance des tumeurs et des troubles inflammatoires.
