Glucocorticoid (GC) hormone action can be modulated at the pre-receptor level by the endoluminal enzyme 11β-hydroxysteroid dehydrogenase type 1 (11βHSD1). 11βHSD1 is a bidirectional enzyme that primarily acts as an oxo-reductase in vivo, converting the pro-hormone cortisone to its active form cortisol, while its dehydrogenase activity results in inactivation of cortisol to cortisone. 11βHSD1 oxo-reductase activity allows GC reactivation in a tissue s...
