Activation requirements for the induction of CD4+CD25+ T cell suppressor function

Thornton, Angela M., Piccirillo, Ciriaco A., Shevach, Ethan M.·2004·European Journal of Immunology

Abstract

The in vivo differentiation/survival of CD4+CD25+ T suppressor cells is dependent on IL‐2 and CD28‐mediated costimulatory signals. To determine the cytokine and costimulatory requirements for CD25+ T cells in vitro, we established a two‐stage culture system where CD25+ T cells were activated in a primary culture. In the subsequent culture, activated CD4+CD25+ cells were then mixed with responders in order to assess their suppressor function. Pre‐culture of CD25+ T cells with anti‐CD3 alone resulted in poor survival and minimal induction of suppressor activity. Pre‐culture in the presence of anti‐CD3 and IL‐2 or IL‐4, but not IL‐6, IL‐7, IL‐9, IL‐10 or IL‐15, resulted in proliferation of the CD25+ cells and induction of potent suppressor function. Inhibition of the interaction of CD28 or cytotoxic T lymphocyte‐associated antigen‐4 (CTLA‐4) with CD80/CD86 in the pre‐culture of CD4+CD25+ cells did not prevent the induction of suppressor function. Furthermore, the inhibition of costimulatory signals did not inhibit the ability of fresh CD25+ T cells to inhibit CD8+ responders under conditions where activation of the responders was independent of CD80/CD86. These studies support the view that activation of CD25+ T cells requires IL‐2/IL‐4 for their survival/differentiation into effector cells, but is independent of CD28/CTLA‐4‐mediated costimulation.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
