Predominance of T-lymphocytes with a high-affinity receptor for sheep red blood cells in the synovial fluid of patients with rheumatoid arthritis. A short communication.

Using different modifications of the spontaneous rosette-forming assay, T-lymphocytes were determined in the synovial fluid and the peripheral blood of patients with rheumatoid arthritis (RA). It was shown that a T-lymphocyte subpopulation, forming E-rosettes by a high affinity receptor for SRBC was enriched in the synovial fluid as compared to the peripheral blood.
