A Reversal in Hair Cell Orientation Organizes Both the Auditory and Vestibular Organs
Frontiers in Neuroscience, 2021 Sensory hair cells detect mechanical stimuli with their hair bundle, an asymmetrical brush of actin-based membrane protrusions, or stereocilia. At the single cell level, stereocilia are organized in rows of graded heights that confer the hair bundle with

Frontiers in Cellular Neuroscience, 2021 Non-mammalian vertebrates can restore their auditory and vestibular hair cells naturally by triggering the regeneration of adjacent supporting cells. The transcription factor ATOH1 is a key regulator of hair cell development and regeneration in the inner

Current Response in CaV1.3–/– Mouse Vestibular and Cochlear Hair Cells
Frontiers in Neuroscience, 2021 Signal transmission by sensory auditory and vestibular hair cells relies upon Ca2+-dependent exocytosis of glutamate. The Ca2+ current in mammalian inner ear hair cells is predominantly carried through CaV1.3 voltage-gated Ca2+ channels.

The Transduction Channel Filter in Auditory Hair Cells [PDF]
The Journal of Neuroscience, 2005 In the first step in auditory transduction, sound-induced vibrations of the stereociliary bundles on the sensory hair cells are converted into electrical signals by opening of mechanotransducer channels. Faithful transduction and hence auditory performance will be limited by the kinetic properties of these channels.

Kölliker’s organ-supporting cells and cochlear auditory development
Frontiers in Molecular Neuroscience, 2022 The Kölliker’s organ is a transient cellular cluster structure in the development of the mammalian cochlea. It gradually degenerates from embryonic columnar cells to cuboidal cells in the internal sulcus at postnatal day 12 (P12)–P14, with the cochlea ...

The Kinocilia of Cochlear Hair Cells: Structures, Functions, and Diseases
Frontiers in Cell and Developmental Biology, 2021 Primary cilia are evolutionarily conserved and highly specialized organelles that protrude from cell membranes. Mutations in genes encoding ciliary proteins can cause structural and functional ciliary defects and consequently multiple diseases ...

Calcium entry into stereocilia drives adaptation of the mechanoelectrical transducer current of mammalian cochlear hair cells [PDF]
, 2014 Mechanotransduction in the auditory and vestibular systems depends on mechanosensitive ion channels in the stereociliary bundles that project from the apical surface of the sensory hair cells.

Abnormal outer hair cell efferent innervation in Hoxb1-dependent sensorineural hearing loss.
PLoS Genetics, 2023 Autosomal recessive mutation of HOXB1 and Hoxb1 causes sensorineural hearing loss in patients and mice, respectively, characterized by the presence of higher auditory thresholds; however, the origin of the defects along the auditory pathway is still ...

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.
