The majority ofthe inflammatory cells invading the synovial tissue of rheumatoid arthritis (RA) palienls has been tlcmonslrated to be of T-cell origin |l-3]. A large proportion of these T cells may be activated, as has been shown using monoclonal antibodies (MoAb) directed against T-cell activation molecules such as hutiian leucocyte antigen (HLA)-DR or the interlcukin-2 (iL2) receptor (0025) (4. 5], Some authors reported A prcdt)minancc of CD4-positivc cells [3| with phcnotypic characteristics of hctpcr-induccr T cells [6j, whereas others found activated CD4 as well as CD8 cells in lymphocyte populations derived from synovia! tissue [5], The presence of activated T cells within the rheumatoid joint strongly suggests a role for these cells in the palhogenesisof RA. Human T-cell clones may. as has been reported for muHne T cells [7]. be categorized as Thl- or Th2-type cells depending

on their functional characteristics [8]. ThI-iypc clones differ from Th2-lypc clones in their cytotoxic potential (Thl»Th2) [8. 9) and their cytokine profile. Thl-type clones producing predominantly lL-2 and IKN-gamma and Th2-type clones producing IL.-4 and IL-5 [8. 10. 11]. Using the anti-CD3-induced cytotoxicily status and the cytokine (IL-I. -2. -4. -6. and IFN-gamma) profile of a panel of clones (/j= 19) obtained from Ihe synovial tissue of a patient with RA as criteria fur Thl or Th2. we investigated whether Thl- or Th2-type eells predominated in this T-eell clone panel. The relevance of our findings in relation to ihc pathogenesis of RA will be discussed.
