Microstructural interactions contribute to the hotspot in the living cochlea

Current Research in Neurobiology, 2022
The mechanism of the active cochlea relies on a complex interaction between microstructures in the organ of Corti. A significant longitudinal vibration “hotspot” was recently observed in the high-frequency region of the living gerbil cochlea between the ...

The tip-link antigen, a protein associated with the transduction complex of sensory hair cells, is protocadherin-15 [PDF]

, 2006
Sound and acceleration are detected by hair bundles, mechanosensory structures located at the apical pole of hair cells in the inner ear. The different elements of the hair bundle, the stereocilia and a kinocilium, are interconnected by a variety of link

Dishevelled genes mediate a conserved mammalian PCP pathway to regulate convergent extension during neurulation [PDF]

, 2006
The planar cell polarity (PCP) pathway is conserved throughout evolution, but it mediates distinct developmental processes. In Drosophila, members of the PCP pathway localize in a polarized fashion to specify the cellular polarity within the plane of the

Molecular and functional characterization of gap junctions in the avian inner ear. [PDF]

, 2006
To analyze the fundamental role of gap junctions in the vertebrate inner ear, we examined molecular and functional characteristics of gap junctional communication (GJC) in the auditory and vestibular system of the chicken.

The Study of Otoacoustic Emissions and the Suppression of Otoacoustic Emissions in Subjects with Tinnitus and Normal Hearing: An Insight to Tinnitus Etiology

International Archives of Otorhinolaryngology, 2015
Introduction Analysis of the suppression effect is a simple method to evaluate cochlear status and central auditory mechanisms and, more specifically, the medial olivocochlear system.

Inner ear is a target for insulin signaling and insulin resistance: evidence from mice and auditory HEI-OC1 cells

BMJ Open Diabetes Research & Care, 2020
ObjectiveThe mechanisms underlying the association between diabetes and inner ear dysfunction are not known yet. The aim of the present study is to evaluate the impact of obesity/insulin resistance on inner ear fluid homeostasis in vivo, and to ...

Metabolic Abnormalities Linked to Auditory Pathways in ApoE-Knockout HEI-OC1 Cells: A Transcription-Metabolism Co-Analysis

Biomolecules, 2022
Lipid transporter protein apolipoprotein E (APOE) has contributed to functional studies of various organ functions. Animals with ApoE knockout (KO) have been used to study atherosclerosis and hyperlipidemia while an increasing number of researchers have ...

SKOOTS: Skeleton‐Oriented Object Segmentation for Mitochondria in High‐Resolution Cochlear EM Datasets

Advanced Science, EarlyView.
Skeleton‐oriented object segmentation (SKOOTS) introduces a new strategy for 3D mitochondrial instance segmentation by predicting explicit skeletons rather than relying on boundary cues. This approach enables robust analysis of densely packed organelles in large FIB‐SEM datasets.

Inner ear hair cells deteriorate in mice engineered to have no or diminished innervation.

Frontiers in Aging Neuroscience, 2015
The innervation of the inner ear critically depends on the two neurotrophins Ntf3 and Bdnf. In contrast to this molecularly well established dependency, evidence regarding the need of innervation for long-term maintenance of inner ear hair cells is ...
