Abstract:
Adropin is a regulatory peptide hormone involved in metabolic homeostasis, cardiovascular protection, and immune modulation. Recent evidence suggests that adropin plays a role in the pathophysiology of autoimmune rheumatic diseases (ARDs) by influencing key processes such as endothelial function, oxidative stress, tissue fibrosis, and immune cell regulation. This review summarizes current knowledge on adropin's biological functions and its relevance in conditions including rheumatoid arthritis, systemic lupus erythematosus, systemic sclerosis, primary Sjögren's syndrome, osteoarthritis, psoriasis, Behçet's disease, and Kawasaki disease. We discuss how adropin interacts with various signaling pathways and highlight its potential role in macrophage polarization, regulatory T cell activity, and fibrotic remodeling. Although data remain limited and sometimes conflicting, altered adropin levels have been observed across several ARDs, suggesting potential utility as a biomarker or therapeutic target. Further research is needed to clarify its clinical significance and translational potential in immune-mediated diseases.
