Abstract

Synovial fluid lymphocytes (SFL) and peripheral blood lymphocytes (PBL) from patients with rheumatoid arthritis (RA) and reactive oligoarthritis were investigated for activated T cells (Ia+SIg-), IL-2 receptor bearing cells (Tac+) and IL-2 production in vivo and in vitro. In contrast to negative results with blood, the synovial fluid of the arthritic joints contains considerable amounts of IL-2 activity (median: 11.8 mu/ml), elevated proportions of Ia+SIg- activated T cells (median: 12.5%) and of IL-2 receptor bearing cells (median: 2.5%). In vitro, after stimulation with several Concanavalin A (Con A) doses, SFL develop proportions of IL-2 receptor cells comparable to PBL. Furthermore, they produce higher values of IL-2 activity than comparable PBL cultures. The proportions of Ia+SIg- activated T cells increase only moderately after Con A stimulation compared to in vivo data, indicating different activated T cell subsets in the synovial fluid (Ia+SIg-, Tac+). The findings are discussed as an expression of an acute hyperactivation of lymphocytes in an inflamed joint.
