Expression data from a 24h time series of dexamethasone treatment for mouse bone marrow derived macrophages

ABSTRACT: Macrophages are amongst the major targets of glucocorticoids (GC) as therapeutic anti-inflammatory agents. Here we show that GC treatment of mouse and human macrophages initiates a cascade of induced gene expression including many anti-inflammatory genes. Inducible binding of the glucocorticoid receptor (GR) was detected at candidate enhancers in the vicinity of induced genes in both species and this was strongly associated with canonical GR binding motifs. However, the sets of inducible genes, the candidate enhancers, and the GR motifs within them, were highly-divergent between the two species.

Glucocorticoid Activation of Anti-Inflammatory Macrophages in Coordination with STAT6 Protects Against Insulin Resistance

Project description:Deletion of the GC receptor (GR) in macrophages in mice, aggravates obesity-related insulin resistance, by reducing anti-inflammatory macrophages, and enhancing adipose tissue inflammation. Consequently, the reduction of anti-inflammatory macrophages leads to exaggerated adipose tissue lipolysis and severe hepatic steatosis. Mechanistically, macrophages deficient for GR show a diminished response to IL-4 driven anti-inflammatory polarization, due to disruption of an epigenetic crosstalk between GC and IL-4 signaling involving synergistic loading of GR and STAT6. Our results demonstrate that GR plays an important role in macrophage polarization during obesity by limiting adipose tissue inflammation and lipolysis to promote insulin sensitivity
