Change in the Th1/Th2 phenotype of memory T-cell clones from rheumatoid arthritis synovium
(1999) In Scandinavian Journal of Immunology 50(1). p.1-9- Abstract
The stability of established memory T helper (Th)1/Th2 cells in chronic inflammatory diseases is not clear, and a shift of the cytokine balance could control chronic inflammation. In order to study the regulation of the Th phenotype of memory T cells, polyclonal T-cell lines and clones with a Th1, Th0 or Th2 phenotype were developed from rheumatoid synovial tissue. Th1 [interleukin (IL)-12 + anti-IL-4] and Th2 (IL-4 + anti-IL-12) promoting environments and IL-2 were used to manipulate the cytokine profile. Polyclonal T-cell lines of predominantly Th1 type could be shifted to produce Th2 cytokines, and polyclonal Th2/Th0 lines could be shifted to produce Th1 cytokines. However, this shift was due to an amplification of CD8+ T cells with... (More)
The stability of established memory T helper (Th)1/Th2 cells in chronic inflammatory diseases is not clear, and a shift of the cytokine balance could control chronic inflammation. In order to study the regulation of the Th phenotype of memory T cells, polyclonal T-cell lines and clones with a Th1, Th0 or Th2 phenotype were developed from rheumatoid synovial tissue. Th1 [interleukin (IL)-12 + anti-IL-4] and Th2 (IL-4 + anti-IL-12) promoting environments and IL-2 were used to manipulate the cytokine profile. Polyclonal T-cell lines of predominantly Th1 type could be shifted to produce Th2 cytokines, and polyclonal Th2/Th0 lines could be shifted to produce Th1 cytokines. However, this shift was due to an amplification of CD8+ T cells with a memory phenotype and a loss of the CD4+ T cells, giving Tc2 or Tc1 profiles, respectively. Th2 clones cultured repeatedly with IL-2 switched to either a Th0 or a Th1 phenotype, while both Th1 and Th0 memory clones kept a stable phenotype. Addition of Th2-promoting conditions strongly reduced the production of both interferon-gamma and IL-17, while Th1-promoting conditions increased the production of these cytokines. These results demonstrate that RA Th2 clones readily switch, while Th1 and Th0 clones are stable. However, induction of Th2 cytokines can be obtained in polyclonal polarized memory T cells due to amplification of Tc2 cells.
