TNF-α inhibits glucocorticoid receptor-induced gene expression by reshaping the GR nuclear cofactor profile.

Glucocorticoid resistance (GCR) is defined as an unresponsiveness to the therapeutic effects, including the antiinflammatory ones of glucocorticoids (GCs) and their receptor, the glucocorticoid receptor (GR). It is a problem in the management of inflammatory diseases and can be congenital as well as acquired. The strong proinflammatory cytokine TNF-alpha (TNF) induces an acute form of GCR, not only in mice, but also in several cell lines: e.

Glucocorticoid receptor dimers control intestinal STAT1 and TNF-induced inflammation in mice.

TNF is an important mediator in numerous inflammatory diseases, e.g., in inflammatory bowel diseases (IBDs).

The nature of the GRE influences the screening for GR-activity enhancing modulators.

Glucocorticoid resistance (GCR), i.e. unresponsiveness to the beneficial anti-inflammatory activities of the glucocorticoid receptor (GR), poses a serious problem in the treatment of inflammatory diseases.

Glucocorticoid resistance as a major drive in sepsis pathology.

Sepsis is an acute systemic inflammatory disease. Glucocorticoids (GCs), which function by binding to the GC receptor GR have very powerful anti-inflammatory activities, yet they are hardly useful in sepsis. We can thus consider sepsis as a GC resistant disease.
