Webb22 okt. 2015 · Here we focused on abnormal development of the organ of Corti followed by degeneration including outer hair cell (OHC) loss. Methods We investigated the crucial factors involved in late-onset degeneration and loss of OHC by ultrastructural observation, immunohistochemistry and protein analysis in our Cx26-deficient mice (Cx26 f/f P0Cre). … Webb24 mars 2024 · The data highlight a conserved function of Pkhd1l1 in hearing and postulate that PKHD1L1 could be a candidate gene for sensorineural hearing loss (SNHL) in humans. Pkhd1l1 is predicted to encode a very large type-I transmembrane protein, but its function has largely remained obscure. Recently, it was shown that Pkhdl1l1 is a …

WebbFor the scientifically minded: This outer hair cell gets thinner when it gets longer and fatter when it gets shorter. Measuring up these changes indicates that the cell volume stays constant. This supports the idea that the ‘motor’ is a molecule whose job it is to change membrane area.

However, how exactly this electromotile effect contributes to the astonishing sensitivity and frequency selectivity of the inner ear has remained unclear.

WebbWhile hair bundles of inner hair cells are of linear shape, those of outer hair cells exhibit a distinctive V-shape. The biophysical rationale behind this morphology, however, remains unknown. Here we use analytical and computational methods to study the fluid flow across rows of differently shaped hair bundles.

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.
