Double Cross‐Linked Hydrogel for Intra‐articular Injection as Modality for Macrophages Metabolic Reprogramming and Therapy of Rheumatoid Arthritis

Advanced Functional Materials, EarlyView.
A hydrogel for intra‐articular injection for the treatment of rheumatoid arthritis (RA) is formulated and comprehensively studied. After administration, the hydrogel induces a metabolic reprogramming of immunometabolism of macrophages to trigger fatty acid oxidation subsequently inducing polarization of anti‐inflammatory M2 macrophages. This results in
