Apparent mineralocorticoid excess syndrome cases recorded worldwide. Liquorice consumption may also cause a temporary form of AME due to its ability to block 11β-hydroxysteroid dehydrogenase type 2, in turn causing increased levels of cortisol. Cessation of licorice consumption will reverse this form of AME. Apparent mineralocorticoid excess syndrome Apparent mineralocorticoid excess (AME) is an autosomal recessive disorder causing hypertension (high blood pressure) and hypokalemia (abnormally low levels of potassium). It was found by Dr Maria I. New at Weil Cornell Hospital in New York City. It results from mutations in the "HSD11B2" gene, which encodes the kidney isozyme of 11β-hydroxysteroid dehydrogenase type 2. In
Subcommissural organ neuronal cell bodies within the subcommissural organ, although the specialized cells receive some innervation from outside neurons. Ependymal cells secrete high molecular mass glycoproteins into the cerebrospinal fluid, in which the bulk of them condense to form a filamentous structure named Reissner’s fiber. The subcommissural organ/Reissner’s fiber complex is thought to be involved in the reabsorption and circulation of the cerebrospinal fluid, and with functions related to electrolyte and water balance. One of the proteins secreted by the subcommissural organ, and which is present in Reissner’s fiber, is spondin. SCO-spondin is a “giant” (5000 amino acids) glycoprotein (thrombospondin superfamily) found
