Autoimmune 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 کاملActin filaments in sensory hairs of inner ear receptor cells
Receptor cells in the ear are excited through the bending of sensory hairs which project in a bundle from their surface. The individual stereocilia of a bundle contain filaments about 5 nm in diameter. The identity of these filaments has been investigated in the crista ampullaris of the frog and guinea pig by a technique of decoration with subfragment-1 of myosin (S-1). After demembranation wit...
متن کاملInside the inner ear
There are dozens of different myosin isozymes, though it's not clear why cells require such a diversity. These images of fluorescently-labelled hair cells from the inner ears of frog, guinea pig and mouse show the localization of actin (red at top left and bottom right) and of four different forms of myosin (green, except at bottom left, where myosin VI is labelled in red). Hair cells are the r...
متن کاملBiomechanics in the Inner Ear
The elongation and contraction of outer hair cells (OHCs) greatly contribute to the high sensitivity and frequency selectivity of the mammalian inner ear. The motility of OHCs is believed to be based on the conformational changes of the motor protein prestin in the plasma membrane of OHCs. In the present study, four lines of research on the inner ear were conducted. First, the mechanism by whic...
متن کاملSp8 regulates inner ear development.
A forward genetic screen of N-ethyl-N-nitrosourea mutagenized Xenopus tropicalis has identified an inner ear mutant named eclipse (ecl). Mutants developed enlarged otic vesicles and various defects of otoconia development; they also showed abnormal circular and inverted swimming patterns. Positional cloning identified specificity protein 8 (sp8), which was previously found to regulate limb and ...
