Perspectives on Auditory Neuropathy: Disorders of Inner Hair Cell, Auditory Nerve, and Their Synapse [PDF]
The term auditory neuropathy (Starr, A. et al., 1996) was first used to describe a hearing disorder due to altered function of the auditory nerve in the presence of preserved functions of cochlear outer hair cells (OHCs; Starr, A. et al., 1991). The hearing loss has specific features reflecting impairment of auditory temporal processes that are ...

Remodeling of the Inner Hair Cell Microtubule Meshwork in a Mouse Model of Auditory Neuropathy AUNA1 [PDF]
AbstractAuditory neuropathy 1 (AUNA1) is a form of human deafness resulting from a point mutation in the 5′ untranslated region of theDiaphanous homolog 3(DIAPH3) gene. Notably, theDIAPH3mutation leads to the overexpression of the DIAPH3 protein, a formin family member involved in cytoskeleton dynamics. Through study of diap3-overexpressing transgenic (

Rat Auditory Inner Hair Cell Mechanotransduction and Stereociliary Membrane Diffusivity Are Similarly Modulated by Calcium [PDF]
The lipid bilayer plays a pivotal role in force transmission to many mechanically-gated channels. We developed the technology to monitor membrane diffusivity in order to test the hypothesis positing that Ca2+ regulates open probability (P o) of cochlear hair cell mechanotransduction (MET) channels via the plasma membrane. The stereociliary membrane was

Artificial induction of Sox21 regulates sensory cell formation in the embryonic chicken inner ear.
During embryonic development, hair cells and support cells in the sensory epithelia of the inner ear derive from progenitors that express Sox2, a member of the SoxB1 family of transcription factors.

Acoustic overexposure and aging can damage auditory synapses in the inner ear by a process known as synaptopathy. These insults may also damage hair bundles and the sensory transduction apparatus in auditory hair cells.

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

Loss of Pex1 in Inner Ear Hair Cells Contributes to Cochlear Synaptopathy and Hearing Loss
Peroxisome Biogenesis Disorders (PBD) and Zellweger syndrome spectrum disorders (ZSD) are rare genetic multisystem disorders that include hearing impairment and are associated with defects in peroxisome assembly, function, or both.

A novel ENU-induced mutation in Myo6 causes vestibular dysfunction and deafness [PDF]
Mouse N-ethyl-N-nitrosourea (ENU) mutagenesis has generated many useful animal models for human diseases. Here we describe the identification of a novel ENU-induced mouse mutant strain Turner (Tur) that displays circling and headtossing behavior and ...

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

Mechanisms of sensorineural cell damage, death and survival in the cochlea. [PDF]
The majority of acquired hearing loss, including presbycusis, is caused by irreversible damage to the sensorineural tissues of the cochlea. This article reviews the intracellular mechanisms that contribute to sensorineural damage in the cochlea, as well ...
