Abstract

Interleukin (IL)-10 and glucocorticoids (GCs) inhibit the ability of antigen-presenting dendritic cells (DCs) to stimulate T lymphocytes. We show that induction of GILZ (GC-induced leucine zipper) is involved in this phenomenon. IL-10, dexamethasone (DEX), and transforming growth factor (TGF)beta stimulate GILZ production in human immature DCs derived from monocytes and from CD34+ cells. GILZ is necessary and sufficient for DEX, IL-10, and TGFbeta modulation of CD80, CD83, CD86, immunoglobulin-like transcript (ILT)-3, and B7-H1 expression by DCs, and alteration of DC functions. GILZ stimulates the production of IL-10 by immature DCs and prevents the production of inflammatory chemokines by CD40L-activated DCs. In contrast, GILZ does not prevent CD40 ligand-mediated inhibition of phagocytosis, indicating that it affects some but not all aspects of DC maturation. GILZ prevents DCs from activating antigen-specific T lymphocyte responses. Administration of GCs to patients stimulates GILZ expression in their circulating antigen-presenting cells, and this contributes to the weak lymphocyte responses of GC-treated patients. Thus, regulation of GILZ expression is an important factor determining the decision of DCs whether or not to stimulate T lymphocytes, and IL-10, GCs, and TGFbeta share this mechanism for influencing DC functions and the balance between immune response and tolerance.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Glucocorticoids can convert dendritic cells to tolerogenic cells that promote regulatory T cell production, and this effect relies on glucocorticoid-mediated expression of GILZ.

    “GCs can also convert DCs to tolerogenic cells, which promote the production of regulatory T cells (38, 39). This immunosuppressive effect critically relies on the GC-mediated expression of glucocorticoid-induce leucine zipper (GILZ), since this transcription factor appears as both necessary and sufficient for the induction of a tolerogenic state (40, 41).”

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.
