It has been established that oligoclonal expansion is a common feature of the CD8+ T cell population, particularly within the CD8+ CD57+ lymphocyte subset. In addition, clonal malignancies involving CD8+ CD57+ T cells (large granulocytic lymphocytic leukemias) are often accompanied by rheumatoid arthritis, Felty's syndrome, or both. Therefore, to identify disease-related alterations in the CD8+ T cell repertoire, we have compared the patterns of oligoclonality in the CD8+ T cells of rheumatoid arthritis patients (n = 32) with those of age-matched controls (n = 25). By using a multiplex PCR assay for the CDR3 length of TCR beta-chains, we have found a striking increase in the frequency of CD8+ oligoclonality involving V beta 3 TCR: 50% of the rheumatoid arthritis patients had evidence of oligoclonality in this TCR family compared with 4% of controls (p < 0.0002). In addition, two unrelated RA patients had clonally dominant CD8+ T cell beta receptors that were identical in amino acid sequence, suggesting selection by a common Ag. An analysis of a subset of RA patients with mAbs specific for V beta 3 TCR revealed the presence of clonal expansion in a minority of patients usually, but not exclusively, involving the CD57+ subset. These data define a phenotype of the T cell repertoire that is strongly associated with rheumatoid arthritis; the mechanisms and genetic and environmental factors that explain this phenomenon remain to be defined.
