Abstract

La présente invention concerne des compositions et des méthodes relatives à des constructions de variants SIRP-a. Les constructions de variants SIRP-a peuvent modifiées de diverses façons pour répondre à des facteurs environnementaux, comme le pH, lhypoxie et/ou la présence d'enzymes associées à une tumeur ou d'antigènes associés à une tumeur. Les constructions selon l'invention peuvent être utilisées pour traiter diverses maladies, comme le cancer, de préférence une tumeur solide ou un cancer hématologique.
