Inner Ear Hair Cell Protection in Mammals against the Noise-Induced Cochlear Damage

Neural Plasticity, 2018
Inner ear hair cells are mechanosensory receptors that perceive mechanical sound and help to decode the sound in order to understand spoken language. Exposure to intense noise may result in the damage to the inner ear hair cells, causing noise-induced ...

Disruption of Hars2 in Cochlear Hair Cells Causes Progressive Mitochondrial Dysfunction and Hearing Loss in Mice

Frontiers in Cellular Neuroscience, 2021
Mutations in a number of genes encoding mitochondrial aminoacyl-tRNA synthetases lead to non-syndromic and/or syndromic sensorineural hearing loss in humans, while their cellular and physiological pathology in cochlea has rarely been investigated in vivo.

Proteomic Analysis Reveals the Composition of Glutamatergic Organelles of Auditory Inner Hair Cells

Molecular & Cellular Proteomics
In the ear, inner hair cells (IHCs) employ sophisticated glutamatergic ribbon synapses with afferent neurons to transmit auditory information to the brain. The presynaptic machinery responsible for neurotransmitter release in IHC synapses includes proteins such as the multi-C2-domain protein otoferlin and the vesicular glutamate transporter 3 (VGluT3).

Development of a Human 3D Immune‐Competent Neurovascular Model Enabling Time‐Resolved Monitoring of Neuroinflammatory Dynamics and Neuroimmune Interactions

Advanced Science, EarlyView.
Neuroinflammation alters blood–brain barrier integrity and contributes to neurological disorders, yet existing models lack human immune complexity. This study presents a 3D, immune‐responsive platform that reconstructs key neurovascular components and enables real‐time monitoring.

PTEN inhibitor bisperoxovanadium protects against noise-induced hearing loss

Neural Regeneration Research, 2023
Studies have shown that phosphatase and tensin homolog deleted on chromosome ten (PTEN) participates in the regulation of cochlear hair cell survival. Bisperoxovanadium protects against neurodegeneration by inhibiting PTEN expression.

Drug-induced stress granule formation protects sensory hair cells in mouse cochlear explants during ototoxicity [PDF]

, 2019
Stress granules regulate RNA translation during cellular stress, a mechanism that is generally presumed to be protective, since stress granule dysregulation caused by mutation or ageing is associated with neurodegenerative disease.

Partial hearing recovery after cochlear nerve surface transplantation of hair follicle‐derived neural crest stem cells in neural hearing loss rat

Animal Models and Experimental Medicine, EarlyView.
This study comprises three experimental parts. Part 1. Time‐course of ouabain‐induced hearing loss. Rats received ouabain (10 mM) via round window application. ABR/DPOAE tests and histological analyses were performed at 2, 7, and 30 days post‐treatment to characterize SGN and glial cell degeneration. Part 2.

A Novel Antigen Sensitive to Calcium Chelation That is Associated with the Tip Links and Kinocilial Links of Sensory Hair Bundles [PDF]

, 2003
Tip links are extracellular, cell-surface-associated filaments of unknown molecular composition that are thought to gate the mechanotransducer channel of the sensory hair cell.

Clade‐wide morphological and functional variation of the sauropsid columella

The Anatomical Record, EarlyView.
Abstract The columella (=stapes) is the middle ear bone of reptiles that transmits vibrations from the environment to the inner ear. It has been shown to exhibit extensive interspecific morphological disparity in several clades; however, its morphological variation and associated functional consequences remain poorly described.

Delayed structural maturation of inner hair cell ribbon synapses in a mouse model of fragile X syndrome

Frontiers in Molecular Neuroscience
Clinical features of the fragile X syndrome (FXS) phenotype include intellectual disability, repetitive behaviors, social communication deficits, and, commonly, auditory hypersensitivity to acoustic stimuli.
