Download or read book Neurosteroids and the Nervous System written by Steven R. King and published by Springer Science & Business Media. This book was released on 2012-11-09 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: While steroids from the periphery have profound effects on the nervous system, the nervous system also produces its own steroids de novo (“neurosteroids”). The physiological importance of neurosteroids is beginning to be understood. These steroids potentially have roles in sedative/hypnotic behavior, anxiety, learning, and memory. At the cellular level, neurosteroids affect neuronal excitability, synaptic plasticity and cell proliferation and survival. Early findings hold promise for future strategies to treat specific psychologicalconditions and neurological diseases. This Brief will focus on the current state of understanding of brainderived neurosteroids.

Download or read book Extrasynaptic GABAA Receptors written by Adam C. Errington and published by Springer. This book was released on 2014-09-22 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: GABA is the principal inhibitory neurotransmitter in the CNS and acts via GABAA and GABAB receptors. Recently, a novel form of GABAA receptor-mediated inhibition, termed “tonic” inhibition, has been described. Whereas synaptic GABAA receptors underlie classical “phasic” GABAA receptor-mediated inhibition (inhibitory postsynaptic currents), tonic GABAA receptor-mediated inhibition results from the activation of extrasynaptic receptors by low concentrations of ambient GABA. Extrasynaptic GABAA receptors are composed of receptor subunits that convey biophysical properties ideally suited to the generation of persistent inhibition and are pharmacologically and functionally distinct from their synaptic counterparts. This book highlights ongoing work examining the properties of recombinant and native extrasynaptic GABAA receptors and their preferential targeting by endogenous and clinically relevant agents. In addition, it emphasizes the important role of extrasynaptic GABAA receptors in GABAergic inhibition throughout the CNS and identifies them as a major player in both physiological and pathophysiological processes.

Download or read book New Perspectives in Neurosteroids action a Special Player Allopregnanolone written by Valerio Magnaghi and published by Frontiers Media SA. This book was released on 2015-07-01 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Early in the 80’s date the first observations on the existence of hormonal steroids that may be synthesized and act in the nervous system. In order to refer to these endogenous steroids, proved important to control both central and peripheral nervous system, it was proposed the term “neurosteroids” (NSs). Over the years, their importance in regulating the physiological functions of neuronal and glial cells increased progressively. These steroids can be involved in several pathophysiological conditions such as depression, anxiety, premenstrual syndrome (PMS), schizophrenia and Alzheimer disease. Among the different classes of NSs, the progestagens revealed particularly important. The progesterone metabolite 5a-pregnan-3a-ol-20-one, also named tetrahydroprogesterone or allopregnanolone (ALLO) was one of the first most important steroid that was originally shown to act as neurosteroid. ALLO is synthesized through the action of the 5aR-3a-HSD, which converts P into DHP and subsequently, via a bidirectional reaction, into ALLO. NSs exert complex effects in the nervous system through ‘classic’, genomic, and ‘non-classic’, non-genomic actions. ALLO displays a rapid ‘non-genomic’ effect, which mainly involves the potent modulation of the GABA type A (GABA-A) receptor function. Recently a membrane receptor has been identified as target for ALLO effects, i.e. the membrane progesterone receptors (mPRs) that are able to activate a signalling cascade through G protein dependent mechanisms. By these ways, ALLO is able to modulate several cell functions, acting as neurogenic molecule on neural progenitor cells, as well as by activating proliferation and differentiation of glial cells in the central and peripheral nervous system. In this topic, we review the most recent acquisitions in the field of neurosteroids, focusing our attention on ALLO because its effects on the physiology of neurons and glial cells of the central and peripheral nervous system are intriguing and could potentially lead to the development of new strategies for neuroprotection and/or regeneration of injured nervous tissues and for the treatment of neuropsychiatric disorders.

Download or read book Steroids and the Nervous System written by Cristin Roth and published by American Medical Publishers. This book was released on 2023-09-19 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A biologically active organic compound with four rings arranged in a specific molecular configuration is termed as a steroid. Steroid hormones are essential for cell life and they affect the neuroendocrine and behavioral functions in humans. Steroids perform two main biological functions. The first function is that they form an essential part of cell membranes which alters the membrane fluidity. The second function is signal transduction or cell signaling that facilitates cellular response. During early development, steroids regulate the activity and plasticity of neurons and the glial cells. They continue to exert trophic and protective effects on the adult nervous system. Steroids are synthesized by the gonads and adrenal glands, and are transmitted to the brain, spinal cord and the peripheral nerves through the bloodstream. Neurosteroids such as pregnenolone, progesterone, dehydroepiandrosterone and sulfate esters are produced within the nervous system. This book unravels the recent studies related to the importance of steroids in the nervous system. The topics covered herein are of utmost significance and bound to provide incredible insights to the readers. Through this book, we attempt to further enlighten the readers about the new concepts in this field of study.
