Receptor-mediated release of inositol phosphates in the cochlear and vestibular sensory epithelia of the rat.
Various neurotransmitters, hormones and other modulators involved in intercellular communication exert their biological action at receptors coupled to phospholipase C (PLC). This enzyme catalyzes the hydrolysis of phosphatidylinositol 4,5-bisphosphate (PtdInsP2) to inositol 1,4,5-trisphosphate (InsP3) and 1,2-diacylglycerol (DG) which act as second messengers. In the organ of Corti of the guine...
متن کاملAsymmetric distribution of prickle-like 2 reveals an early underlying polarization of vestibular sensory epithelia in the inner ear.
Vestibular hair cells have a distinct planar cell polarity (PCP) manifest in the morphology of their stereocilia bundles and the asymmetric localization of their kinocilia. In the utricle and saccule the hair cells are arranged in an orderly array about an abrupt line of reversal that separates fields of cells with opposite polarity. We report that the putative PCP protein Prickle-like 2 (Pk2) ...
متن کاملMorphological and Histochemical Analysis of the Human Vestibular Fold
The larynx is divided into the supraglottic, glottic and subglottic regions, each serving different functions. The false vocal cords, also known as the ventricular or vestibular folds, are two thick, sagittally oriented, individually sized mucosal duplications arising from the wall into the lumen of the supraglottic space and forming the medial wall of the laryngeal ventricle (Kutta et al., 2004).
متن کاملEffect of aging on myo-inositol and phosphoinositide metabolism in the cochlear and vestibular sensory epithelia of the rat.
Neurotransmission and transmembrane signaling are among the cellular mechanisms affected in the aging nervous system. In the inner ear, the phosphoinositide second messenger cascade is of particular interest as a target of the aging process. In both the cochlear (CSE) and vestibular sensory epithelia (VSE), the hydrolysis of phosphatidylinositol 4,5-bisphosphate (PtdInsP2) to the second messeng...
متن کاملUnconventional Myosins in Inner-Ear Sensory Epithelia
To understand how cells differentially use the dozens of myosin isozymes present in each genome, we examined the distribution of four unconventional myosin isozymes in the inner ear, a tissue that is particularly reliant on actin-rich structures and unconventional myosin isozymes. Of the four isozymes, each from a different class, three are expressed in the hair cells of amphibia and mammals. I...
