Molecular mechanisms of glucocorticoid resistance in splenocytes of socially stressed male mice

Quan, N·2003·Journal of Neuroimmunology

Abstract

Splenocytes from socially stressed male mice display functional glucocorticoid (GC) resistance, viz., the antiproliferative effects of GC on lipopolysaccharide (LPS)-stimulated splenocytes is absent. In this study, we investigated changes in the structure and function of the glucocorticoid receptor (GR) in socially stressed animals. Changes of GR at both DNA and RNA levels were excluded. Reduced GR function was restricted to macrophages (CD11b(+)) in association with impaired nuclear translocation of GR after GC stimulation. Consequently, GC failed to block the activation of NF-kappa B in these cells. Thus, impaired nuclear translocation of GR and the lack of transcriptional suppression of NF-kappa B by GC were identified as the molecular mechanisms responsible for the observed GC resistance in spleens of socially stressed mice.

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.
