general. Rheumatoid arthritis (RA) is an autoimmune pathology the etiology of which is still
obscure. Although a multifactorial pathogenesis has been hypothesized, the precise
mechanisms leading to the disease are still poorly understood at the molecular level. miRNA
expression profile analysis highlighted that miR-223 is the only miRNA that is strikingly …
