Among an increasing number of citrullinated proteins identified as antigens for autoantibodies in RA, peptides of citrullinated fibrinogen β (cFIBβ) 4, citrullinated vimentin (cVIM) 5, citrullinated α‐enolase peptide 1 (CEP‐1) 6, and citrullinated tenascin‐C (cTNC5) 7 are well characterized, and have been confirmed as diagnostically sensitive and specific in independent cohorts. Here, VIM is linked to rheumatoid arthritis.
