LIGAND OF REGULATING IMMUNE RESPONSE, AND USE THEREOF IN TREATING AN IMMUNE RESPONSE-RELATED DISEASE

摘要

The present invention relates to a ligand to regulate immune response, i.e., PACAP27 which is one of pituitary adenylate cyclase-activating polypeptides and Serum amyloid A (SAA), and their novel use in treating or preventing diseases associated with immune response. More specifically, the present invention relates to a complex of PACAP27-FPRL1 having a regulatory effect on immune response, and a use thereof in regulating immune response. In another aspect, the present invention relates to a complex of SAA and FPRL1, and a use thereof in inhibiting synoviocyte hyperplasia and angiogenesis and treating or preventing inflammatory diseases including Rheumatoid arthritis (RA).
