This study explores the complex mechanisms between Rheumatoid Arthritis (RA) and cellular senescence, with a focus on the role of four key genes (MMP1, CCL7, CXCL1, HK3) identified through transcriptome analysis in the GEO database. These genes are closely related to IL-17 signalling and the pathogenesis of RA. In a macrophage senescence model induced by hydrogen peroxide (H
