Cell biology of mechanotransduction in inner-ear hair cells
The cloning of deafness genes, especially those for Usher syndrome, has helped to identify a variety of structural proteins involved in the development and function of hair-cell stereocilia. These include novel cadherins, a handful of myosin motors, and scaffolding proteins. Yet a new understanding of these proteins has upended the orthodox view of mechanosensation by hair cells.
متن کاملAutoimmune Inner Ear Disease- A Clinical Viewpoint
Recent developments in medicine have given us a better insight into a group of disorders known as autoimmune diseases. In particular, advances have occurred in our understanding of the Autoimmune Inner Ear Disease (AIED). In this article, the authors review the different postulated theories in the pathogenesis of this disease. The clinical presentation, the available para-clinical diagnostic to...
متن کاملMechanotransduction in mouse inner ear hair cells requires transmembrane channel-like genes.
Inner ear hair cells convert the mechanical stimuli of sound, gravity, and head movement into electrical signals. This mechanotransduction process is initiated by opening of cation channels near the tips of hair cell stereocilia. Since the identity of these ion channels is unknown, and mutations in the gene encoding transmembrane channel-like 1 (TMC1) cause hearing loss without vestibular dysfu...
متن کاملHCN Channels Are Not Required for Mechanotransduction in Sensory Hair Cells of the Mouse Inner Ear
The molecular composition of the hair cell transduction channel has not been identified. Here we explore the novel hypothesis that hair cell transduction channels include HCN subunits. The HCN family of ion channels includes four members, HCN1-4. They were originally identified as the molecular correlates of the hyperpolarization-activated, cyclic nucleotide gated ion channels that carry curren...
متن کاملPolycystin-1 is required for stereocilia structure but not for mechanotransduction in inner ear hair cells.
The polycystic kidney disease-1 (Pkd1) gene encodes a large transmembrane protein (polycystin-1, or PC-1) that is reported to function as a fluid flow sensor in the kidney. As a member of the transient receptor potential family, PC-1 has also been hypothesized to play a role in the elusive mechanoelectrical transduction (MET) channel in inner ear hair cells. Here, we analyze two independent mou...
