Type II spiral ganglion afferent neurons drive medial olivocochlear reflex suppression of the cochlear amplifier. [PDF]
The dynamic adjustment of hearing sensitivity and frequency selectivity is mediated by the medial olivocochlear efferent reflex, which suppresses the gain of the 'cochlear amplifier' in each ear.

Radiotherapy‐Induced Otitis Media With Effusion in Nasopharyngeal Carcinoma: A Meta‐Analysis
This meta‐analysis of eight studies comprising 582 NPC patients provides the first quantitative synthesis of radiotherapy‐induced otitis media with effusion (OME), demonstrating a significant overall risk difference of 0.18 (95% CI: −0.06 to 0.42, p < 0.0001) in OME naive ears.

Connexin-mediated signaling in nonsensory cells is crucial for the development of sensory inner hair cells in the mouse cochlea [PDF]
open9siMutations in the genes encoding for gap junction proteins connexin 26 (Cx26) and connexin 30 (Cx30) have been linked to syndromic and nonsyndromic hearing loss in mice and humans.

A synaptic F-actin network controls otoferlin-dependent exocytosis in auditory inner hair cells
We show that a cage-shaped F-actin network is essential for maintaining a tight spatial organization of Cav1.3 Ca2+ channels at the synaptic ribbons of auditory inner hair cells. This F-actin network is also found to provide mechanosensitivity to the Cav1.3 channels when varying intracellular hydrostatic pressure. Furthermore, this F-actin mesh network

Otogenic route of meningitis was associated with greater cochlear hair cell loss in comparison with the meningogenic one in this otopathology study. Neuronal depletion has been traditionally implicated in failed hearing rehabilitation of post‐meningitis deafness.

Postnatal maturation of auditory-nerve heterogeneity, as seen in spatial gradients of synapse morphology in the inner hair cell area [PDF]
Auditory nerve fibers in the adult ear are divided into functional subgroups according to spontaneous rate (SR) and threshold sensitivity. The high-threshold, low-SR fibers are morphologically and spatially distinct from the low-threshold high-SR fibers at their synaptic contacts with inner hair cells.

Advances in GPCRs Associated With Wnt Signaling Within the Auditory System
ABSTRACT G protein‐coupled receptors (GPCRs) that interact with the Wnt signaling pathway are pivotal for auditory system homeostasis, as they orchestrate inner ear development, hair cell (HC) regeneration, and hearing preservation. Frizzled (FZD) receptors, the core Wnt‐related GPCRs, bind Wnt ligands and co‐receptors (e.g., LRP5/6) to activate both ...

Tone-in-noise detection deficits in elderly patients with clinically normal hearing [PDF]
One of the most common complaints among the elderly is the inability to understand speech in noisy environments. In many cases, these deficits are due to age-related hearing loss; however, some of the elderly that have difficulty hearing in noise have ...

Jervell and Lange‐Nielsen Syndrome Related Clinical Genetics and Experimental Models
ABSTRACT Jervell and Lange‐Nielsen syndrome (JLNS) is defined by electrocardiographic QT prolongation and sensorineural hearing loss, caused by homozygous or compound heterozygous variants in KCNQ1 and/or KCNE1. KCNQ1 encodes the alpha subunit Kv7.1 of the ion channels accountable for slow delayed rectifier potassium currents (IKs), whereas KCNE1 ...

Conditional Tnfaip6-Knockout in Inner Ear Hair Cells Does not Alter Auditory Function
Noise-induced hearing loss is a worldwide public health issue that is characterized by temporary or permanent changes in hearing sensitivity. This condition is closely linked to inflammatory responses, and interventions targeting the inflammatory gene tumor necrosis factor-alpha (TNFα) are known to mitigate cochlear noise damage. TNFα-induced proteins (
