Development of cochlear spiral ligament fibrocytes of the common marmoset, a nonhuman model animal

open access: yesScientific Reports, 2023
Spiral ligament fibrocytes generate potassium gradients, which hair cells require to convert mechanical sound waves into electrical palsy. Together with the stria vascularis, they regulate endolymph electrolyte homeostasis.

Endolymph Composition: Paradigm or Inevitability?

open access: yesPhysiological Research, 2018
This review is focused on the unusual composition of the endolymph of the inner ear and its function in mechanoelectrical transduction. The role of K+ and Ca2+ in excitatory influx, the very low Na+, Ca2+ and Mg2+ concentrations of endolymph, stereocilia structure of hair cells and some proteins involved in mechanosensory signal transduction with ...

FM1-43 reveals membrane recycling in adult inner hair cells of the mammalian cochlea [PDF]

open access: yes, 2002
Neural transmission of complex sounds demands fast and sustained rates of synaptic release from the primary cochlear receptors, the inner hair cells (IHCs). The cells therefore require efficient membrane recycling.

Missing perilymph but leaking blood-endolymph and vestibulocochlear nerve barriers in idiopathic sudden sensorineural hearing loss: A case study

open access: yesJournal of Otology, 2020
Objectives: To evaluate the pathological changes in the blood-perilymph, blood-endolymph, and blood-nerve barriers of a patient with idiopathic sudden sensorineural hearing loss (SSNHL).

Stem Cells Injected into the Deaf Rat Cochlea via Round Window Could Survive for at Least One Week in the Endolymph

open access: yesOtorhinolaryngology and Facial Plastic Surgery, 2022
Background: Noise-induced hearing loss (NIHL) is caused by chronic exposure to high-intensity sound. Although noise hazard has been extensively studied in the past decades, cochlear implants and hearing aids are only safe and clinically effective ...

Electrogenic transport and K(+) ion channel expression by the human endolymphatic sac epithelium. [PDF]

open access: yes, 2015
The endolymphatic sac (ES) is a cystic organ that is a part of the inner ear and is connected to the cochlea and vestibule. The ES is thought to be involved in inner ear ion homeostasis and fluid volume regulation for the maintenance of hearing and ...

In vivo genetic manipulation of inner ear connexin expression by bovine adeno-Associated viral vectors [PDF]

open access: yes, 2017
We have previously shown that in vitro transduction with bovine adeno-associated viral (BAAV) vectors restores connexin expression and rescues gap junction coupling in cochlear organotypic cultures from connexin-deficient mice that are models DFNB1 ...

Three-Dimensional Volumetric Measurement of Endolymphatic Hydrops in Meniere's Disease

open access: yesFrontiers in Neurology, 2021
Objective: We used volumetric three-dimensional (3D) analysis to quantitatively evaluate the extent of endolymphatic hydrops (EH) in the entire inner ear.

Low Endolymph Calcium Concentrations in deafwaddler2J Mice Suggest that PMCA2 Contributes to Endolymph Calcium Maintenance [PDF]

open access: yesJournal of the Association for Research in Otolaryngology, 2004
In vertebrates, transduction of sound into an electrochemical signal is carried out by hair cells that rely on calcium to perform specialized functions. The apical surfaces of hair cells are surrounded by endolymphatic fluid containing calcium at concentrations that must be maintained by active transport. The mechanism of this transport is unknown, but
