Adrenomedullin: new inhibitory regulator for cortisol synthesis and secretion

Preterm birth is associated with immaturity of several crucial physiological functions notably those prevailing in the lung and kidney. Recently, a steroid secretion deficiency was identified in very preterm neonates, associated with a partial yet transient deficiency in 11β-hydroxylase activity, sustaining cortisol synthesis. However, the P450c11β enzyme is expressed in preterm adrenal glands, we hypothesized an inhibition of cortisol...
