Hair cell ribbon synapses [PDF]
Cell and Tissue Research, 2006 Hearing and balance rely on the faithful synaptic coding of mechanical input by the auditory and vestibular hair cells of the inner ear. Mechanical deflection of their stereocilia causes the opening of mechanosensitive channels, resulting in hair cell depolarization, which controls the release of glutamate at ribbon-type synapses.

Transmission Disrupted: Modeling Auditory Synaptopathy in Zebrafish
Frontiers in Cell and Developmental Biology, 2018 Sensorineural hearing loss is the most common form of hearing loss in humans, and results from either dysfunction in hair cells, the sensory receptors of sound, or the neurons that innervate hair cells.

The Micromachinery of Mechanotransduction in Hair Cells [PDF]
Annual Review of Neuroscience, 2007 Mechanical stimuli generated by head movements and changes in sound pressure are detected by hair cells with amazing speed and sensitivity. The mechanosensitive organelle, the hair bundle, is a highly elaborated structure of actin-based stereocilia arranged in precise rows of increasing height.

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

Mutations in ap1b1 Cause Mistargeting of the Na(+)/K(+)-ATPase Pump in Sensory Hair Cells. [PDF]
, 2013 The hair cells of the inner ear are polarized epithelial cells with a specialized structure at the apical surface, the mechanosensitive hair bundle.

Keratin-mediated hair growth and its underlying biological mechanism
Communications Biology, 2022 Injecting human hair-derived keratin into mice skin accelerates hair growth & formation, as TGFβ2 secretion during hair destruction stimulates epithelial cell death and keratin release, leading to dermal cell condensation & hair growth.

Magnetic actuation of hair cells [PDF]
Applied Physics Letters, 2011 The bullfrog sacculus contains mechanically sensitive hair cells whose stereociliary bundles oscillate spontaneously when decoupled from the overlying membrane. Steady-state offsets on the resting position of a hair bundle can suppress or modulate this native motility.

Active hair bundle movements in auditory hair cells [PDF]
The Journal of Physiology, 2006 The frequency selectivity of mammalian hearing depends on not only the passive mechanics of the basilar membrane but also an active amplification of the mechanical stimulus by the cochlear hair cells. The common view is that amplification stems from the somatic motility of the outer hair cells (OHCs), changes in their length impelled by voltage ...

Release and elementary mechanisms of nitric oxide in hair cells
, 2010 The enzyme nitric oxide (NO) synthase, that produces the signaling molecule NO, has been identified in several cell types in the inner ear. However, it is unclear whether a measurable quantity of NO is released in the inner ear to confer specific ...

The challenge of hair cell regeneration [PDF]
Experimental Biology and Medicine, 2010 Sensory hair cells of the inner ear are responsible for translating auditory or vestibular stimuli into electrical energy that can be perceived by the nervous system. Although hair cells are exquisitely mechanically sensitive, they can be easily damaged by excessive stimulation by ototoxic drugs and by the effects of aging.
