Abstract

OBJECTIVE: To compare the cytokine expression profile of three CD8+, three CD4+, and three gammadelta+ T cell clones all derived from the synovial fluids of three patients with reactive arthritis (ReA). METHODS: Complementary DNA based microarrays containing the specific sequence of 56 cytokine transcripts were used for screening. Selected genes were confirmed by reverse transcriptase-polymerase chain reaction assay. RESULTS: Microarray showed that transcripts encoding for interferon gamma and tumour necrosis factor alpha were expressed by all CD8+ and CD4+ T cell clones. However, gammadelta+ T cells predominantly expressed transforming growth factor beta2 and granulocyte monocyte-colony stimulating factor. CONCLUSION: T lymphocyte clones from the joint of patients with ReA exhibit differential cytokine expression profiles. CD8+ and CD4+ T cells demonstrate a Th1 mediated profile, whereas gammadelta+ T cells show a more heterogeneous and less proinflammatory Th3 driven pattern
