Rheumatoid arthritis (RA) is a multisystemic disease with synovial inflammation its most characteristic finding.'Although the etiology of RA remains elusive, there are now several lines of evidence that suggcst Tap cells play an important role in the pathogenesis of rheumatoid synovial inflammation. A significant obstacle to the further delineation of the nature of T-cell involvement in RA has been the lack of identification of an RA-relevant antigen. Studies testing synovial-derived T-cells' reactivity against putative disease-relevant antigens have been inconclusive. In view of this void in our understanding, alternative approaches including examination of the clonally distributed T-cell receptor (TCRaP) expressed by synovial-derived T-cells have been carried out. These studies have attempted to identify a biased or restricted TCR repertoire, which would suggest a pathogenetic mechanism of antigen/autoantigen or superantigen-induced T-cell expansion. Due to limitations of both the number of available anti-human TCR antibodies and of the number of cells obtaincd from the joint, these studies have utilized the polymerase chain reaction (PCR) for analysis of the TCR repertoire. Possible biased or restricted usage of TCR in RA was suggested by the finding of restricted clonality among the pathogenic T-cells in some animal models of autoimmunity. For example, in experimental allergic encephalomyelitis, a disease model with similarities to multiple sclerosis, analysis of myelin basic protein-reactive, encephalitogcnic T-cells has revealed a limited clonal response as evidenced by a restricted TCRap repert~ ire.~.~ The finding of a restricted TCR repertoire in EAE has led to the use of antibody therapy directed against the variable (V) region of the TCR for the prevention and amelioration of disease. 24To date, however, studies of the synovial TCR repertoire in RA have yielded conflicting results. A possible explanation for this variability is the common use of synovium obtained from patients with long-standing disease. In these cases detection of the disease-relevant TCR may be obscured by recruitment of nonspecific cclls or diversification of antigen reactivity. In the current study we have examined the TCR Vp gene family repertoire of synovial T-cells from patients with early stage RA. Our findings are discussed in the context of the results from the other studies that have examined the TCR repertoire in RA.
