Abstract:
Methods and compositions for inhibiting interleukin-21 (IL-21)/IL-21 receptor (MU-1) activity using antagonists of IL-21 or IL-21 receptor (“IL-21R” or “MU-1”), are disclosed. IL-21/IL-21R antagonists can be used to induce immune suppression in vivo, e.g., for treating, ameliorating or preventing autoimmune or inflammatory disorders, including, e.g., inflammatory bowel disease (IBD), rheumatoid arthritis (RA), transplant/graft rejection, psoriasis, asthma, fibrosis, and systemic lupus erythematosus (SLE).
