Possibilities of Inner Ear Barrier Models for Otologic Drug Development

Advanced Therapeutics, EarlyView.
This review examines innovative organ chip models that reconstruct critical inner ear barriers, addressing a fundamental challenge in otologic drug development: the limited understanding of pharmaceutical behavior across these complex barriers. By replicating these barriers, the advanced models offer promising alternatives to traditional testing ...

Insights into the regulation of hearing regeneration

Frontiers in Audiology and Otology
Our perception of sound is mediated by sound-sensitive hair cells in the inner ear, located in a specialized neuro-epithelium that transmits information to the auditory cortex via the auditory pathway.

LRRC8A Regulates Outer Hair Cell Volume and Electromotility and is Required for Hearing

Advanced Science, EarlyView.
This study identifies LRRC8A‐dependent volume‐regulated anion channels (VRACs) as essential for cochlear outer hair cells' electromotility and auditory signal amplification. LRRC8A deficiency disrupts cell volume control, impairs auditory sensitivity, and causes deafness, while targeted LRRC8A re‐expression restores auditory function.

Cracking the Valence Code: Patterned Facial Kinematics and Neural Signatures of Emotional Expressions in Mice

Advanced Science, EarlyView.
An AI‐powered system decodes emotional valence from mouse facial expressions, identifying ear dynamics as key indicators. By integrating facial kinematics with synchronized neural recordings, this approach establishes a direct link between behavior and brain activity, advancing automated emotion recognition in animal models.

Loss of auditory sensitivity from inner hair cell synaptopathy can be centrally compensated in the young but not old brain [PDF]

Neurobiology of Aging, 2016
A dramatic shift in societal demographics will lead to rapid growth in the number of older people with hearing deficits. Poorer performance in suprathreshold speech understanding and temporal processing with age has been previously linked with progressing inner hair cell (IHC) synaptopathy that precedes age-dependent elevation of auditory thresholds ...

Auditory Hair Cell Mechanotransduction Channels Dynamically Shape the Mechanical Properties of Their Membrane Environment

Advanced Science, EarlyView.
This work shows, for the first time, that the stereocilia membrane in cochlear hair cells is dynamically regulated by the mechanotransduction channel to impact the membrane mechanical properties. This work provides direct evidence that the opening and closing associated with the MET channel is regulating the membrane viscosity suggesting that the MET ...

Hair bundles of cochlear outer hair cells are shaped to minimize their fluid-dynamic resistance

Scientific Reports, 2017
The mammalian sense of hearing relies on two types of sensory cells: inner hair cells transmit the auditory stimulus to the brain, while outer hair cells mechanically modulate the stimulus through active feedback.

Expression and Localization of CaBP Ca2+ Binding Proteins in the Mouse Cochlea. [PDF]

PLoS ONE, 2016
CaBPs are a family of EF-hand Ca2+ binding proteins that are structurally similar to calmodulin. CaBPs can interact with, and yet differentially modulate, effectors that are regulated by calmodulin, such as Cav1 voltage-gated Ca2+ channels ...

Comparative Cochlear Transcriptomics in Echolocating Bats and Mouse Reveals Hras as Protector Against Noise‐Induced Hearing Loss

Advanced Science, EarlyView.
Comparative cochlear transcriptomics of noise‐exposed bats (Miniopterus fuliginosus) and mice reveals bat‐specific protection mechanisms for noise‐induced hearing loss (NIHL), identifying Hras as a key hub regulator. Functional studies in mice show hair‐cell‐specific Hras overexpression significantly reduced hair‐cell damage and NIHL by activating the ...

Insights into the Biology of Hearing and Deafness Revealed by Single-Cell RNA Sequencing

Cell Reports, 2019
Summary: Single-cell RNA sequencing is a powerful tool by which to characterize the transcriptional profile of low-abundance cell types, but its application to the inner ear has been hampered by the bony labyrinth, tissue sparsity, and difficulty ...
