| Research Abstract |
Endogenous secretory receptor for advanced glycation endproducts (esRAGE) can act as decoy receptor of HMGB1 involved in progression of rheumatoid arthritis. Tagging with an acidic oligopeptide (AcOP), bone-targeting carrier, was enable to augment bone distribution of esRAGE, while retaining function as decoy receptor. Moreover AcOP-tagged esRAGE retained in bone at least one week after intravenous injection. In rheumatoid arthritis model mice, weekly injection of AcOP-tagged esRAGE attenuated swelling of four limbs more effectively than untagged esRAGE. Thus bone-targeting system with an acidic oligopeptide is applicable to esRAGE as potential agent of rheumatoid arthritis.
