Owing to their anti-inflammatory effects, steroid therapy using glucocorticoids (GCs) is still part of the treatment of rheumatoid arthritis (RA), despite several severe side effects like glucocorticoid-induced osteoporosis (GIO). Until now the molecular mechanisms underlying the beneficial and side effects of GC therapy are poorly understood. GCs exert their actions via the glucocorticoid receptor (GR) that alters gene expression by either binding as a dimer to GC response el...

Glucocorticoids (GCs) are widely used to treat chronic inflammatory diseases such as rheumatoid (RA) and lead to multiple side effects including glucocorticoid induced osteoporosis (GIO). Our work challenges the dogma that transrepression of pro-inflammatory genes by the glucocorticoid receptor (GR) is solely responsible for reducing inflammation, whereas transactivation of genes is causing side effects.Using conditional and function selective mutant mic...
