    Mineralocorticoids induce polyuria by reducing apical aquaporin-2 expression of the kidney in partial vasopressin deficiency Read more
    Editor's pick

    It is well recognized that a line of symptoms of neurohypophyseal diabetes insipidus (NDI), also known as arginine vasopressin (AVP) deficiency, are masked under the condition of adrenal insufficiency. However, molecular mechanisms whereby polyuria manifests after the administration of glucocorticoids in patients with masked NDI have not been fully elucidated. Kurimoto J and colleague elegantly solved this long-lasting enigma via comprehensive analyses including patients with masked NDI as well as murine model of familial NDI. They provide a convincing proof that mineralcorticoids directly attenuate the expression of aquaporin-2 in the apical membrane of collecting duct, thereby leading to the increase in urine volume in patients with NDI.
