Do synovial tissue lymphocytes from patients with rheumatoid arthritis exhibit altered immunoglobulin production and T-cell regulatory functions compared to peripheral blood lymphocytes from normal donors?
Synovial lymphocytes in rheumatoid arthritis demonstrate localized immunological abnormalities, specifically increased immunoglobulin production and deficient suppressor T-cell activity.
Westermark et al. (1979) studied this question.
