WebbOuter hair cells (OHCs) are the sensory receptors which are responsible for amplifying sound signals. Thus, the damage or loss of OHCs is the common cause of CDDP ototoxicity. 9,10 Targeting otoprotective agents to OHCs in the organ of Corti by nanomedicine strategies is crucial for curing ototoxicity relative to the pathology of OHCs.

Here, we have studied how ER stress elicits hair cell pathology, using mouse models with inactivation of Manf (mesencephalic astrocyte-derived neurotrophic factor), encoding an ER-homeostasis-promoting protein.

Webb17 jan. 2024 · In 1985, Bill Brownell and colleagues published the remarkable observation that cochlear outer hair cells (OHCs) express voltage-driven mechanical motion: electromotility. They proposed OHC electromotility as the mechanism for the elusive “cochlear amplifier” required to explain the sensitivity of mammalian hearing.
