Cutting Edge: Control of CD8+ T Cell Activation by CD4+CD25+ Immunoregulatory Cells

Open access

Abstract

CD4+CD25+ regulatory T cells inhibit organ-specific autoimmune diseases induced by CD4+CD25− T cells and are potent suppressors of CD4+CD25− T cell activation in vitro. We demonstrate that CD4+CD25+ T cells also suppress both proliferation and IFN-γ production by CD8+ T cells induced either by polyclonal or Ag-specific stimuli. CD4+CD25+ T cells inhibit the activation of CD8+ responders by inhibiting both IL-2 production and up-regulation of IL-2Rα-chain (CD25) expression. Suppression is mediated via a T-T interaction as activated CD4+CD25+ T cells suppress the responses of TCR-transgenic CD8+ T cells stimulated with soluble peptide-MHC class I tetramers in the complete absence of APC. These results broaden the immunoregulatory role played by CD4+CD25+ T cells in the prevention of autoimmune diseases, but also raise the possibility that they may hinder the induction of effector CD8+ T cells to tumor or foreign Ags.

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.
