Abstract
La présente invention concerne l'utilisation d'un anticorps anti-cd25, qui n'inhibe pas l'interaction il-2-cd25, avec une liaison améliorée pour activer des rs gamma fc qui conduisent à un épuisement efficace de cellules treg infiltrant les tumeurs et une meilleure maîtrise de tumeurs établies. Selon l'invention, la combinaison avec des anticorps anti-protéine-1 de mort cellulaire programmée améliore en outre le rejet tumoral.
