Excerpt
Autoantibodies to deiminated (citrullinated) forms of the α and β chains of fibrin (AhFibA), also known as antifilaggrin autoantibodies (AFA), are the most specific serological markers of rheumatoid arthritis (RA). Deimination is critical in generating the AhFibA epitopes and, in the synovial tissue (ST), deiminated fibrin is their major antigenic target. Existence of fibrin deimination specifically in RA patients could explain why the AhFibA response is RA specific. …
