Zinc-finger protein A20 protects hair cells from damage made by high-power microwave

Journal of Bio-X Research, 2019
. Inner ear hair cells are important for maintaining hearing. Irreversible damage to hair cells is an important cause of sensorineural deafness. Electromagnetic radiation, especially high-power microwave, is an important threat to human health in modern ...

Quantitative Analysis Linking Inner Hair Cell Voltage Changes and Postsynaptic Conductance Change: A Modelling Study [PDF]

, 2015
This paper presents a computational model which estimates the postsynaptic conductance change of mammalian Type I afferent peripheral process when airborne acoustic waves impact on the tympanic membrane. A model of the human auditory periphery is used to

Age-related changes in auditory nerve–inner hair cell connections, hair cell numbers, auditory brain stem response and gap detection in UM-HET4 mice [PDF]

Neuroscience, 2015
This study compared the timing of appearance of three components of age-related hearing loss that determine the pattern and severity of presbycusis: the functional and structural pathologies of sensory cells and neurons and changes in gap detection (GD), the latter as an indicator of auditory temporal processing.

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

Cellular glutathione content in the organ of Corti and its role during ototoxicity. [PDF]

, 2015
Glutathione (GSH) is the major scavenger of reactive oxygen species (ROS) inside cells. We used live confocal imaging in order to clarify the role of GSH in the biology of the organ of Corti, the sensory epithelium of the cochlea, before, during and ...

Mechanisms of synaptic depression at the hair cell ribbon synapse that support auditory nerve function [PDF]

, 2017
Inner hair cells (IHCs) in the cochlea are the mammalian phono-receptors, transducing sound energy into graded changes in membrane potentials, the so called “receptor potentials.” Ribbon synapses between IHCs and auditory nerve neurons are responsible ...

Enlargement of ribbons in zebrafish hair cells increases calcium currents, but disrupts afferent spontaneous activity and timing of stimulus onset. [PDF]

, 2017
In sensory hair cells of auditory and vestibular organs, the ribbon synapse is required for the precise encoding of a wide range of complex stimuli. Hair cells have a unique presynaptic structure-the synaptic ribbon-that organizes both synaptic vesicles ...

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.

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

, 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 ...

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
