Protective effect of astaxanthin nanoemulsion on mammalian inner ear hair cells [PDF]

PeerJ, 2023
Background Aminoglycoside antibiotics are used for treating certain acute infections. However, these drugs cause ototoxicity by inducing inner ear hair cell death.

Striatin Is Required for Hearing and Affects Inner Hair Cells and Ribbon Synapses

Frontiers in Cell and Developmental Biology, 2020
Striatin, a subunit of the serine/threonine phosphatase PP2A, is a core member of the conserved striatin-interacting phosphatase and kinase (STRIPAK) complexes. The protein is expressed in the cell junctions between epithelial cells, which play a role in

Different Contribution of Missense and Loss-of-Function Variants to the Genetic Structure of Familial and Sporadic Meniere Disease. [PDF]

MedComm (2020)
This study examines the genetic basis of sporadic (SMD) and familial Meniere disease (FMD) by comparing rare protein‐coding variants using exome sequencing and gene burden analysis. FMD patients had a higher accumulation of missense and LoF variants, especially in genes linked to auditory and vestibular function.

Differences in auditory nerve fiber responses in regard to inner and outer hair cells [PDF]

The Journal of the Acoustical Society of America, 1978
Single unit recordings were made from auditory nerve fibers in the monkey to pure tone stimuli. Extensive studies of frequency response areas suggested the existence of two types of auditory nerve fibers. One type showed a flat-bottomed response area and the other showed a conventional sharp one.

A Reversal in Hair Cell Orientation Organizes Both the Auditory and Vestibular Organs

Frontiers in Neuroscience, 2021
Sensory hair cells detect mechanical stimuli with their hair bundle, an asymmetrical brush of actin-based membrane protrusions, or stereocilia. At the single cell level, stereocilia are organized in rows of graded heights that confer the hair bundle with

Evaluation of inner hair cell and nerve fiber loss as sufficient pathologies underlying auditory neuropathy [PDF]

Hearing Research, 2009
Auditory neuropathy is a hearing disorder characterized by normal function of outer hair cells, evidenced by intact cochlear microphonic (CM) potentials and otoacoustic emissions (OAEs), with absent or severely dys-synchronized auditory brainstem responses (ABRs).

The lhfpl5 Ohnologs lhfpl5a and lhfpl5b Are Required for Mechanotransduction in Distinct Populations of Sensory Hair Cells in Zebrafish

Frontiers in Molecular Neuroscience, 2020
Hair cells sense and transmit auditory, vestibular, and hydrodynamic information by converting mechanical stimuli into electrical signals. This process of mechano-electrical transduction (MET) requires a mechanically gated channel localized in the apical

Spiking Pattern of the Mouse Developing Inner Hair Cells Is Mostly Invariant Along the Tonotopic Axis

Frontiers in Cellular Neuroscience, 2018
During development, the sensory cells of the cochlea, the inner hair cells (IHCs), fire spontaneous calcium action potentials. This activity at the pre-hearing stage allows the IHCs to autonomously excite the auditory nerve fibers and hence, represents ...

Mechanotransduction is required for establishing and maintaining mature inner hair cells and regulating efferent innervation

Nature Communications, 2018
Mechanoelectrical transducer (MET) channels on the tips of inner hair cells are essential for transducing auditory sensory information. Here, the authors show that disrupting MET channel function also prevents the preservation of normal inner hair cell ...

Behavioral auditory thresholds and loss of ribbon synapses at inner hair cells in aged gerbils

Experimental Gerontology, 2016
The potential contribution of auditory synaptopathy to age dependent hearing loss was studied in groups of young and old gerbils. The analysis of the number of inner hair cell ribbon synapses in aged gerbils (37.9±3.3months of age) revealed only a relatively small (11-17%) loss in the basal two thirds of the cochlea, while a more pronounced reduction ...
