Inositol Lipids and Signal Transduction in the Nervous System: An Update

Inositol Lipids and Signal Transduction in the Nervous System: An Update Abstract: The role that inositol lipids play in cellular signaling events in eukaryotic cells remains one of the most intensively investigated areas of cell biology. In this respect, phosphoinositide‐mediated signal transduction in the CNS is no exception; major advances have been made since a previous review on this subject (Fisher and Agranoff, 1987). Not only have stimulated phosphoinositide turnover and its physiological sequelae been demonstrated repeatedly in a variety of neural preparations, but, in addition, the detailed molecular mechanisms underlying these events continue to unfold. Here we review the progress that has occurred in selected aspects of this topic since 1987. In the first two sections of this article, emphasis is placed on novel functional roles for the inositol lipids and on recent insights into the molecular characteristics and regulation of three key components of the phosphoinositide signal transduction system, namely, the inositol lipid kinases, phospholipases C (PLCs), and the inositol 1,4,5‐trisphosphate(I(1,4,5)P3) receptor. The metabolic fate of I(1,4,5)P3 in neural tissues, as well as its control, is also detailed. Later we focus on identification of the multiple receptor subtypes that are coupled to inositol lipid turnover and discuss possible strategies for intervention into phosphoinositide‐mediated signal transduction. Due to space limitations, an extensive evaluation of the diacylglycerol/protein kinase C (DAG/PKC) limb of the signal transduction pathway is not included (for reviews, see Nishizuka, 1988; Kanoh et al., 1990). http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Neurochemistry Wiley

Abstract

Abstract: The role that inositol lipids play in cellular signaling events in eukaryotic cells remains one of the most intensively investigated areas of cell biology. In this respect, phosphoinositide‐mediated signal transduction in the CNS is no exception; major advances have been made since a previous review on this subject (Fisher and Agranoff, 1987). Not only have stimulated phosphoinositide turnover and its physiological sequelae been demonstrated repeatedly in a variety of neural preparations, but, in addition, the detailed molecular mechanisms underlying these events continue to unfold. Here we review the progress that has occurred in selected aspects of this topic since 1987. In the first two sections of this article, emphasis is placed on novel functional roles for the inositol lipids and on recent insights into the molecular characteristics and regulation of three key components of the phosphoinositide signal transduction system, namely, the inositol lipid kinases, phospholipases C (PLCs), and the inositol 1,4,5‐trisphosphate(I(1,4,5)P3) receptor. The metabolic fate of I(1,4,5)P3 in neural tissues, as well as its control, is also detailed. Later we focus on identification of the multiple receptor subtypes that are coupled to inositol lipid turnover and discuss possible strategies for intervention into phosphoinositide‐mediated signal transduction. Due to space limitations, an extensive evaluation of the diacylglycerol/protein kinase C (DAG/PKC) limb of the signal transduction pathway is not included (for reviews, see Nishizuka, 1988; Kanoh et al., 1990).
