pubmed:abstractText |
Rheumatoid arthritis is an autoimmune disease which is characterized by chronic polyarthritis and joint destruction as well as by extra-articular manifestations, typically including the appearance of rheumatoid nodules. Although the pathogenesis of the disease is unknown, substantial evidence suggests that it is T cell-mediated. In contrast to experimental models, the disease-mediating T cells in the human situation have never been isolated or identified. We expanded T lymphocytes from human rheumatoid nodules by IL-2 stimulation and observed a marked oligoclonality among these expanded lymphocytes. This tendency towards oligoclonality was not seen in IL-2-expanded lymphocytes from peripheral blood. We hypothesize that this oligoclonal expansion reflects a clonally restricted in situ preactivation of lymphocytes and that precisely these preactivated cells are involved in the pathogenesis of the rheumatic process.
