Outline of Final Research Achievements |
The unique ionic environment of endolymph is produced by various ion pumps and transporters in the stria vascularis and spiral ligament. However, acid-base regulation of the inner ear is unclear including the treatment of H+ arose from the pumps to maintain the endolymph. In the present study, (1) 20 pH regulatory membrane proteins were found in the stria vascularis by LC-MS/MS. (2) The in vivo measurement system to monitor the endolymph pH was established in order to investigate the involvement of the pH regulatory proteins in the pH regulation of the inner ear.
