Abstract

Conclusions: Endolymph homeostasis is thought to be mediated by the vasopressin-aquaporin-2 (VP-AQP2) system in the inner ear. Endolymphatic hydrops, the morphological characteristics of Ménière's disease (MD), seems to reflect the malregulation of the VP-AQP2 system in inner ear fluid. The elevation of plasma vasopressin (p-VP) level, which is often observed in MD and its related diseases, might be one of the causative factors underlying these diseases.

Purpose of review: Review of the role of the VP-AQP2 system in the inner ear fluid homeostasis and in the formation and development of endolymphatic hydrops.

Recent clinical and experimental findings: A clinical survey has revealed that the p-VP level is often elevated in MD and its related diseases and that the increase in the p-VP level was closely linked to vertigo attacks in MD. Experimental studies have revealed that proteins and mRNAs of aquaporin-2 and vasopressin type 2 receptor were expressed in the stria vascularis of the cochlea and the epithelium of the endolymphatic sac, and that the volume of the endolymphatic compartment was mediated by the activity of the VP-AQP2 system in the inner ear.
