How do mechanically gated ion channels in stereocilia open and close?

The organ of Corti contains tiny hair cells with stereocilia at the ends. Stereocilia are delicate, hair-like projections that react to cochlea fluid movement. Jan 4, 2021 ... show that ADF/cofilin-1 are recruited to mechanotransducing auditory stereocilia tips, where they increase the availability of F-actin barbed. You are studying the mechanism by which stereocilia in inner ear hair cells bend and transduce a ... staining reveals that it is located at the base of ... Feb 22, 2024 ... Loud noise is causing zinc, normally localized to stereocilia, to be blasted over many Zinc in the inner ear is concentrated in stereocilia ... Deflection of the bundle of stereocilia is mechanically responsible for stretching ion pores in the stereocilia, allowing a cation current to pass into the cell ... Oct 19, 2022 ...
