Identification and Characterization of TMEM119-Positive Cells in the Postnatal and Adult Murine Cochlea

open access: yesBrain Sciences, 2023
Transmembrane protein 119 (TMEM119) is expressed in a subset of resident macrophage cells of the brain and was proposed as a marker for native brain microglia. The presence of cells expressing TMEM119 in the cochlea has not yet been described.

Monitoring blood-flow in the mouse cochlea using an endoscopic laser speckle contrast imaging system. [PDF]

open access: yesPLoS ONE, 2018
Laser speckle contrast imaging (LSCI) enables continuous high-resolution assessment of microcirculation in real-time. We applied an endoscope to LSCI to measure cochlear blood-flow in an ischemia-reperfusion mouse model.

Cellular reprogramming with ATOH1, GFI1, and POU4F3 implicate epigenetic changes and cell-cell signaling as obstacles to hair cell regeneration in mature mammals

open access: yeseLife, 2022
Reprogramming of the cochlea with hair-cell-specific transcription factors such as ATOH1 has been proposed as a potential therapeutic strategy for hearing loss.

Variations in cochlea shape reveal different evolutionary adaptations in primates and rodents

open access: yesScientific Reports, 2023
The presence of a coiled cochlea is a unique feature of the therian inner ear. While some aspects of the cochlea are already known to affect hearing capacities, the full extent of the relationships between the morphology and function of this organ are ...

Modeling cochlear micromechanics: hypotheses and models

open access: yesJournal of Bio-X Research, 2019
. The cochlea plays an important role in the mammalian auditory system. Sound-induced cell motion in the cochlea is transformed into electrical signals that are then sent to primary auditory neurons.

Steady streaming as a method for drug delivery to the inner ear

open access: yesScientific Reports, 2021
The inner ear, or cochlea, is a fluid-filled organ housing the mechanosensitive hair cells. Sound stimulation is relayed to the hair cells through waves that propagate on the elastic basilar membrane.

Microstructural interactions contribute to the hotspot in the living cochlea

open access: yesCurrent Research in Neurobiology, 2022
The mechanism of the active cochlea relies on a complex interaction between microstructures in the organ of Corti. A significant longitudinal vibration “hotspot” was recently observed in the high-frequency region of the living gerbil cochlea between the ...
