  • YERSINIA-ENTEROCOLITICA ACTIVATES A T-HELPER TYPE-1-LIKE T-CELL SUBSET IN REACTIVE ARTHRITIS JOURNAL OF IMMUNOLOGY Lahesmaa, R., Yssel, H., Batsford, S., Luukkainen, R., MOTTONEN, T., Steinman, L., Peltz, G. 1992; 148 (10): 3079-3085

    Abstract:

    The profile of lymphokines secreted by 14 T cell clones and 24 T cell lines reactive with Yersinia Ag isolated from the synovial fluid cells of two HLA-B27+ patients with Yersinia-triggered reactive arthritis was characterized. In response to Ag-specific or -nonspecific stimulation, all of the Yersinia-reactive T cell clones and lines had a pattern of lymphokine secretion resembling that of murine (Th1) cells. A total of 50% of T cell lines and clones randomly isolated from a reactive arthritis patient, without prior in vitro stimulation with Yersinia Ag, also exhibited a Th1-like profile of cytokine secretion upon nonspecific activation. This indicates that the selective expansion of this subset of T cells had already occurred in vivo. The possibility that the predominance of Th1-like T cells was an artefact generated by the T cell cloning procedure was excluded; 50% of the randomly isolated T cell clones and lines produced IL-4, IL-5, or both cytokines upon nonspecific activation. These results indicate that Yersinia Ag selectively activate a Th1-like subset of T cells in patients with Yersinia-triggered reactive arthritis. Accumulation of such cells in the synovial tissue of patients with reactive arthritis may play a key role in the pathogenesis of this disease.
