Book Synopsis Endogenous Neuroprotection by : Bernhard Schaller
Download or read book Endogenous Neuroprotection written by Bernhard Schaller and published by Nova Publishers. This book was released on 2008 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Endogenous neuoprotection is a phenomenon where a brief episode of ischemia renders the brain resistant against a subsequent longer-asting ischemia event. Experimentally, the author was able to model hypoxic preconditioning in animal model. Increasing knowledge of this endogenous neuroprotectin by ischemic tolerance may help to minimize neuronal damage following ischemic stroke and hypoxic encephalopathy. This book is, therefore, the first overview of this important topic and will certainly influence further investigations in clinical and neuroscience research.

Available in PDF, EPUB and Kindle. Book excerpt: SOLOMON H. SNYDER Receptor Research Reaches Neurology: Relevance to Neurodegenerative Diseases and Stroke President George Bush has heralded the 1990s as the decade of the brain, based largely on the rapid escalation of advances in the molecular neuro sciences and the likelihood that these will bear therapeutic fruit before the turn of the century. There is little doubt that the 1970s and 1980s have witnessed more remarkable advances in the molecular neurosciences than all of the preceding hundred years. Identification of receptor sites for drugs and neurotransmitters along with simple, sensitive, and specific means of monitoring them has made it possible to elucidate the mechanism of action for many known drugs and to identify new chemical entities as potential therapeutic agents. At the same time, the numbers of distinct neurotrans mitters have multiplied. Prior to 1970 only the biogenic amines were well accepted as transmitters. The early 1970s witnessed the gradual acceptance of amino acids as major excitatory and inhibitory neurotransmitters. Identification of opiate receptors and the subsequent identification of the enkephalins as their endogenous ligands led to an appreciation of peptides as putative transmitters and the accumulation of as many as a hundred neuropeptides by the decade's end. In the 1980s the revolutions of molecular biology have been applied aggressively to the neurosciences with molecular cloning for neuropeptide precursors, many important neurochemical en zymes, and receptors for numerous transmitters.
Book Synopsis Endogenous Neuroprotection in the Respiratory Control System by :
Download or read book Endogenous Neuroprotection in the Respiratory Control System written by and published by . This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Breathing must be robust and highly adaptable to maintain adequate oxygen and CO2 levels during birth, development, pregnancy, and disease. This is achieved by a delicate balance of inhibitory and excitatory neuronal signaling. Both sustained, and intermittent changes in respiratory neuron activity can create long-lasting changes in respiratory motor output (i.e., plasticity). As a constant requirement from birth until death, the respiratory control system must have endogenous mechanisms to maintain appropriate excitability during physiological or pathological stress, and express multiple types of plasticity. Reproduction is an example of an essential biological function with serious maternal and fetal risks. During late pregnancy, maternal brain allopregnanolone levels increase and augment the function of inhibitory GABAA receptors (GABAARs), posing the risk of excessively inhibiting respiratory neurons. Here, we show that respiratory-related hypoglossal motoneurons increase epsilon subunit incorporation into GABAA receptors, which confers insensitivity to allopregnanolone. Similarly, brain allopregnanolone levels increase during the critical period in respiratory control development (occurs during the second postnatal week). We also found that epsilon subunit-containing GABAARs dynamically change in respiratory-related brain regions during the second postnatal week. Thus, increased epsilon subunit incorporation in GABAARs appears to protect breathing from excessive inhibition during pregnancy and postnatal development under physiological conditions. Thus, these studies suggest that adjusting GABAAR subunit composition may be a little recognized, fundamental property of the respiratory control network. On the other hand, pregnancy and the neonatal period are also associated with pathological events, such as ischemic stroke. One potential strategy for protecting neurons from ischemia is to apply principles learned from ischemia-hypoxia resistant extremophile vertebrates, such as activating delta opioid receptors (DORs). We hypothesized that activating spinal DORs would prolong respiratory output (i.e., provide neuroprotection) during oxygen-glucose deprivation (OGD; in vitro stroke model). We found that spinal DOR activation provides flexible neuroprotection against OGD, regardless of whether DOR drugs are applied to the spinal cord before, during or after the onset of OGD. These studies suggest that understanding and controlling endogenous protective mechanisms is a compelling strategy for developing novel therapies and treatments to protect neuronal function against ischemia.
Book Synopsis Innate Tolerance in the CNS by : Jeffrey M. Gidday
Download or read book Innate Tolerance in the CNS written by Jeffrey M. Gidday and published by Springer Science & Business Media. This book was released on 2012-09-21 with total page 685 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cerebral preconditioning is a phenomenon wherein a mild insult or stress induces cellular and tissue adaptation or tolerance to a later, severe injury, therefore reflecting the efficacy of endogenous mechanisms of cerebrovascular protection. Initially identified for rapid cardiac protection, preconditioning has expanded to all aspects of CNS protection from ischemia, trauma and potentially neurodegeneration. Many different stimuli or stressors have been identified as preconditioning agents, suggesting a downstream convergence of mechanisms and underscoring the potential for translational application of preconditioning in the clinic. Moreover, the fundamental mechanisms responsible for preconditioning-induced tolerance will help in the design novel pharmacological approaches for neuroprotection. While stroke and many other brain injuries are not predictable, in some populations (e.g., metabolic syndrome, patients undergoing carotid endarterectomy, aneurysm clipping, or with recent TIAs) the risk for stroke is identifiable and significant, and preconditioning may represent a useful strategy for neuroprotection. For unpredictable injuries, post-conditioning the brain – or inducing endogenous protective mechanisms after the initial injury – can also abrogate the extent of injury. Finally, remote pre- and post-conditioning methods have been developed in animals, and are now being tested in clinical trials, wherein a brief, noninjurious stress to a noncerebral tissue (i.e., skeletal muscle) can provide protection to the CNS and thereby allows clinicians the opportunity to circumvent concerns regarding the direct preconditioning of neurological tissues.

Available in PDF, EPUB and Kindle. Book excerpt: Neuroprotection has been placed on a firm scientific basis during the past decade due to an improved understanding of the molecular basis of neurological diseases and the knowledge that treatment of neurological disorders should not be merely symptomatic but preventative against the progression of the underlying disease, as well as regenerative. The Handbook of Neuroprotection serves as a comprehensive review of neuroprotection based on knowledge of the molecular basis of neurological disorders. Neuroprotective effects of older, established drugs, as well as new drugs in development, are well documented in this detailed volume, featuring the most cutting-edge and innovative methods currently in use. In-depth and authoritative, The Handbook of Neuroprotection features a compendium of vital knowledge aimed at providing researchers with an essential reference for this key neurological area of study.
Book Synopsis Mechanisms of Innate Neuroprotection by : Giuseppe Pignataro
Download or read book Mechanisms of Innate Neuroprotection written by Giuseppe Pignataro and published by Frontiers Media SA. This book was released on 2016-07-27 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: As clinical trials of pharmacological neuroprotective strategies in stroke have been disappointing, attention has turned to the brain's own endogenous strategies for neuroprotection. Two endogenous mechanisms have been recently characterized, ischemic preconditioning and ischemic postconditioning. In the present topic newly characterized mechanisms involved in preconditioning- and postconditioning- neuroprotection will be discussed. The understanding of the mechanisms involved in the neuroprotective pathways induced by preconditioning and postconditioning will be clinically relevant for identifying new druggable target for neurodegenerative disorder therapy. Furthermore, the importance of these neuroprotective strategies resides in that it might be easily translatable into clinical practice. Therefore, the data presented here will highlight the capacity of ischemic preconditioning and postconditioning to be of benefit to humans.
Book Synopsis Endogenous and Exogenous Neuroprotection by Neurotrophic Factors in the Mammalian Retina by : Daniel Matthew Paskowitz
Download or read book Endogenous and Exogenous Neuroprotection by Neurotrophic Factors in the Mammalian Retina written by Daniel Matthew Paskowitz and published by . This book was released on 2006 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neurotrophic factors play central roles in the developing and mature nervous system by promoting neuronal survival. The discovery in 1990 that an exogenously supplied neurotrophic factor could slow the progression of photoreceptor loss in an animal model of retinal degeneration has given rise to an active field of research whose ultimate goal is to develop neuroprotective therapy for patients with blinding diseases. At the same time, a growing body of evidence suggests that endogenously expressed neurotrophic factors maintain retinal health and mediate retinal responses to stress throughout life. This thesis investigates both the requirement for retinal expression of neurotrophic factors in a model of endogenous neuroprotection, and the activity of exogenous factors in a clinically relevant new model of retinal injury.

Book Synopsis Neuroprotective Agents by : William Slikker, Jr
Download or read book Neuroprotective Agents written by William Slikker, Jr and published by Wiley-Blackwell. This book was released on 2005-09-23 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: As life expectancy has increased, so has the incidence of neurodegenerative diseases, particularly those associated with aging. Contributing to increased life expectancy is increased survival following brain injury, stroke, and procedures such as heart surgery, but these events can impair neurological function. The wide range of contributions to this volume, from a detailed paper on the use of gene therapy in combination with hypothermia for the treatment of cerebral ischemia to a comprehensive poster describing the role of anesthetic agents in neurotoxicity during development and senescence, illustrate the scientific scope presented. Contributions from clinical and basic science researchers from many disciplines address various approaches to providing neuroprotection. The clinical focus is on the complexity of neuroprotection, the need for understanding the time-course effects of hypoxia/ischemia, and the need for combinational and time-course applications of multiple therapies. New technologies are introduced for describing both the insult and the treatment necessary for neuroprotection, including gene expression assays (genomics) and gene therapy. Several chapters are devoted to the examination of the predictive value of models for outcome measures in clinical ischemic stroke neuroprotective trials. The need to move from in vitro models to more predictive in vivo approaches with the use of pharmacokinetics is addressed. Other chapters emphasize the role of endogenous agents such as nitric oxide, melatonin, L-carnitine, and estrogens in acute and chronic neural injury and therapy.

Download or read book CNS Neuroprotection written by Frank W. Marcoux and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 509 pages. Available in PDF, EPUB and Kindle. Book excerpt: "CNS neuroprotection" was a common subject of papers, symposia, and reviews during the previous "decade of the brain. " Indeed, in recent years, experimental study of putative neuroprotective agents prompted clinical trials of numerous drug candidates in acute and chronic human neurodegenerative conditions. While the outcomes of these trials have not been as successful as initially hoped, these were early explorations, and the pipeline of relevant ideas continues to grow in strength and depth. We predict that early in this new millennium, crippling disorders such as stroke and Alzheimer's disease will be treated effectively by therapeutic neuroprotective strategies. This volume of the Handbook of Experimental Pharmacology titled eNS Neuroprotection provides a pharmacological perspective on currently promis ing neuroprotective approaches, and a clinical perspective on the challenges involved in establishing the efficacy of these approaches through appropriate clinical trials. Section I, "Mechanistic Approaches to CNS Neuroprotection," reviews major injury mechanisms that have formed the basis for many past and present clinical trials conducted around the world. Dr. KIM and colleagues, Washington University School of Medicine, review the status of blocking excitotoxicity as an approach to CNS neuroprotection. Dr. WANG, Pfizer Global Research and Development,Ann Arbor Laboratories, outlines evidence supporting a contri bution of apoptosis to pathological neuronal or glial cell loss. Drs. BECKER and HALLENBECK, University of Washington and the National Institute on Neuro logical Diseases and Stroke, respectively, argue that inhibiting inflammatory pathways in the brain can be neuroprotective.
