We present, here, a few thoughts on the mechanisms involved in the development ofsymptoms in rheumatoid arthritis (RA) following a study of cellular and humoral parameters.The PPD skin reaction was used as an in vivo index and was markedly decreased in 11 out of 58 cases tested. The DNCB skin test, however, was positive in 40 of a total58 cases, 12 of these showing hyper-reactivity. T-lymphocytes causing rosette formation of sheep erythrocytes were used as an in vitro index, and were present in decreased numbers, 44.3±15.7 (control 50.6±13.6) . Despite this, there was a slightly increased reaction to PHA.B-lymphocytes indicative of surface immunoglobulin were found in increased numbers (35.9±20.8 ; control 24.6±9.8). There was no correlation between the numbers of B-lymphocytesand RF, but patients with an increased sedimentation rate had an increase in B-lymphocytes.Inhibition of migration was demonstrated with MIT and LIT using both antigenic material from synovial tissue and also heat-denatured IgG. Moreover, it was possible to show thatsensitization to these antigens was present in the patients with RA. There was no correlationbetween LIT, the antigenic material of heat-denatured IgG, and RF. The followingpoints were suggested by our findings : 1. Both qualitative and quantitative abnormalitiesof T- and B-lymphocytes were present in RA ; 2. The abnormalities of cellular immunityhad occurred in response to antigens of synovial tissue and heat-denatured IgG ; 3. Therewas no sighificant correlation between cellular and hormonal indices.
