Association of MHC and rheumatoid arthritis. Association of RA with HLA-DR4: the role of repertoire selection.

Abstract excerpt

Most patients with rheumatoid arthritis (RA) express HLA-DR4, HLA-DR1 or HLA-DR10. These alleles share a common amino acid motif in their third hypervariable regions: the shared epitope. In normals and patients with RA, HLA-DR genes exert a major influence on the CD4 alpha beta T-cell repertoire, as shown by studies of AV and BV gene usage and by BV BJ gene usage by peripheral blood CD4 alpha beta T-cells....
