摘要:
High affinity CD47 reagents are provided, which (i) comprise at least one amino acid change relative to the wild-type protein; and (ii) have an increased affinity for a SIRPα relative to the wild-type protein. Compositions and methods are provided for modulating phagocytosis in a mammal by administering a therapeutic dose of a pharmaceutical composition comprising a high affinity CD47 reagent, which blocks the physiological binding interaction between SIRPα and a ligand, e.g., native CD47.
