Abstract

La presente invención proporciona anticuerpos que se unen a Tie2 y métodos de uso de los mismos. Según ciertas realizaciones de la invención, los anticuerpos son anticuerpos completamente humanos que se unen a Tie2 humano y bloquean la interacción 5 entre Tie2 y uno o más ligandos de Tie2, tales como angiopoyetina 1 (Ang1), angiopoyetina 2 (Ang2), angiopoyetina 3 (Ang3) y/o angiopoyetina 4 (Ang4). Los anticuerpos de la invención son útiles, entre otros, para el tratamiento de enfermedades y trastornos asociados a una o más actividades biológicas de Tie2, que incluyen la angiogénesis.
