Static length changes of cochlear outer hair cells can tune low-frequency hearing.
PLoS Computational Biology, 2018 The cochlea not only transduces sound-induced vibration into neural spikes, it also amplifies weak sound to boost its detection. Actuators of this active process are sensory outer hair cells in the organ of Corti, whereas the inner hair cells transduce ...

C1ql1 is expressed in adult outer hair cells of the cochlea in a tonotopic gradient.
PLoS ONE, 2021 Hearing depends on the transduction of sounds into neural signals by the inner hair cells of the cochlea. Cochleae also have outer hair cells with unique electromotile properties that increase auditory sensitivity, but they are particularly susceptible ...

Mechanisms of sensorineural cell damage, death and survival in the cochlea. [PDF]
, 2015 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 ...

Perspectives on Auditory Neuropathy: Disorders of Inner Hair Cell, Auditory Nerve, and Their Synapse [PDF]
, 2008 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 ...

Sensory Transduction and Adaptation in Inner and Outer Hair Cells of the Mouse Auditory System [PDF]
Journal of Neurophysiology, 2007 Auditory function in the mammalian inner ear is optimized by collaboration of two classes of sensory cells known as inner and outer hair cells. Outer hair cells amplify and tune sound stimuli that are transduced and transmitted by inner hair cells. Although they subserve distinct functions, they share a number of common properties. Here we compare the

Artificial induction of Sox21 regulates sensory cell formation in the embryonic chicken inner ear.
PLoS ONE, 2012 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.

eLife, 2021 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.

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 ...

Loss of Pex1 in Inner Ear Hair Cells Contributes to Cochlear Synaptopathy and Hearing Loss
Cells, 2022 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.
