Brief Summary:This study uncovers a novel mechanism for the anti-inflammatory effects of glucocorticoids (GCs) that involves reprogramming of mitochondrial metabolism in macrophages through enhanced production of the anti-inflammatory metabolite itaconate and consequent inhibition of the inflammatory response. GCs have very potent anti-inflammatory properties, but the mechanisms are incompletely understood. GCs also have severe side effects when used in high doses for long-ter...
