Abstract

a presente invenção, em diversos aspectos e modalidades, envolve métodos para o tratamento da permeabilidade vascular relacionada ao tie2 através da administração de um ou mais peptídeo biomiméticos derivados do colágeno iv e envolve composições para o tratamento da permeabilidade vascular relacionada ao tie2 compreendendo um ou mais peptídeo biomiméticos derivados do colágeno iv. esses peptídeos podem promover as atividades agonistas de tie2 da angiopoietina 2 (ang2), estabilizando, desse modo, a vasculatura e/ou os vasos linfáticos.
