MODULATION OF PD-1 INTERACTIONS WITH ITS LIGANDS

摘要

Disclosed are methods for downmodulating an immune response comprising contacting an immune cell with an agent that modulates the interaction between PD-1 and a PD-1 ligand (e.g., soluble forms of PD-1 or PD-1 ligand or antibodies to PD-1) to thereby modulate the immune response.
