Desmopressin can produce ELH and make the expression of AQP2 stronger in inner ears of guinea pigs. The result indicates that ELH may correlate to upregulation of AQP2, but the mechanism is not clear. There are two hypothesis which maybe explain the phenomena: the structural changes of AQP2 in ELS which inhibit the absorption of endolymph; or the relative deficiency of absorption of endolymph caused by the less increase of AQP2 in ELS than that of stria vascularis.

豚鼠腹腔注射去氨加压素能产生膜迷路积水，并使内耳中AQP2的表达增强，说明膜迷路积水可能与AQP2表达上调有关，其详细机理不清，目前有两种推测：内淋巴囊AQP2虽然表达增加，但构型改变，功能降低，减少了内淋巴的吸收；或者内淋巴囊中AQP2的增加少于血管纹AQP2的增加，内淋巴的吸收相对不足。
