Objective. To identify the T lymphocytes that mediate disease in rheumatoid arthritis (RA).Methods. A panel of monoclonal antibodies reactive with T cell receptor (TCR) Vβ gene products was used to analyze the RA T cell repertoire.Results. Of 5 TCR Vβ gene products studied, only Vβ17‐positive T cells were increased in peripheral blood and synovial fluid (SF) from RA patients, compared with controls (P< 0.01 andP= 0.0006, respectively). Thirty‐one percent of the 49 RA SF samples and none of the 19 non‐RA SF samples contained >10% Vβ17‐positive T cells. Activated (Tac‐positive) T cells were enriched among Vβ17‐positive synovial T cells.Conclusion. The selective increase of Vβ17‐positive T cells suggests a role for those T cells in the pathogenesis of RA.
