TL;DR: It is demonstrated that the deafness protein myosin-VIIa and its isoforms are essential for tensioning the tip link, thereby sensitizing the auditory receptor cell’s mechanotransduction process.
Journal ArticleDOI
Decades-old model of slow adaptation in sensory hair cells is not supported in mammals.
TL;DR: Using cochlear and vestibular hair cells of mice, rats, and gerbils, how modulating adaptation affected hair-bundle creep is assessed and results are consistent with slow adaptation requiring myosin motors.
Journal ArticleDOI
Hair bundle stimulation mode modifies manifestations of mechanotransduction adaptation
TL;DR: Existing data is reconciled and it is shown that calcium entry does not drive the fastest adaptation process, independent of the stimulation method, confirming that fast adaptation does not depend on calcium entry.
Journal ArticleDOI
Mechanotransduction in mammalian sensory hair cells
Giusy A. Caprara,Anthony W. Peng +1 more
TL;DR: In this paper , the authors discuss the molecules essential for mechanotransduction and the properties of the mechanOTransduction process, focusing their attention on recent data and differences between the auditory and vestibular systems.
Journal ArticleDOI
Evidence for Altered Ca2+ Handling in Growth Associated Protein 43-Knockout Skeletal Muscle
Giusy A. Caprara,Caterina Morabito,Stefano Perni,Riccardo Navarra,Simone Guarnieri,Maria A. Mariggiò +5 more
TL;DR: GAP43 expression is involved in timing of muscle maturation in-vivo, and the emerging hypothesis indicates that GAP43 interacts with calmodulin to indirectly modulate the activities of dihydropyridine and ryanodine Ca2+ channels, from functional excitation-contraction coupling, to cell metabolism, and gene expression.
