Neural Regulation of Metabolism


Book Description

This book systemically describes the mechanisms underlying the neural regulation of metabolism. Metabolic diseases, including obesity and its associated conditions, currently affect more than 500 million people worldwide. Recent research has shown that the neural regulation of metabolism is a central mechanism that controls metabolic status physiologically and pathophysiologically. The book first introduces the latest studies on the neural and cellular mechanisms of hypothalamic neurons, hypothalamic glial cells, neural circuitries, cellular signaling pathways, and synaptic plasticity in the control of appetite, body weight, feeding-related behaviors and metabolic disorders. It then summarizes the humoral mechanisms by which critical adipocyte-derived hormones and lipoprotein lipase regulate lipid and glucose metabolism, and examines the role of the hypothalamus-sympathetic nerve, a critical nerve pathway from CNS to peripheral nervous system (PNS), in the regulation of metabolism in multiple tissues/organs. Furthermore, the book discusses the functions of adipose tissue in energy metabolism. Lastly, it explores dietary interventions to treat neural diseases and some of the emerging technologies used to study the neural regulation of metabolism. Presenting cutting-edge developments in the neural regulation of metabolism, the book is a valuable reference resource for graduate students and researchers in the field of neuroscience and metabolism.




Neuron Signaling in Metabolic Regulation


Book Description

This book focuses on neuron signaling in the regulation of metabolism and body weight, and especially on methods used in these studies. Obesity and related metabolic syndromes have reached epidemic status, but still are no effective strategies for prevention and treatment. Body weight homeostasis is maintained by balanced food intake and energy expenditure, both of which are under the control of brain neurons. In the recent years, significant progress has been made in identifying specific neurons, neural pathways, and non-neuron cells in feeding regulation, as well as in delineating autonomic nervous systems targeting peripheral metabolic tissues in the regulation of energy expenditure and metabolism. This book reviews recent progress on important neuron signaling for body weight and metabolic regulation and the state-of-the-art methods that has been applied in this field, ranging from animal models with neuron-specific manipulations, pharmacology, optogenetics, in vivo Ca2+ imaging, and viral tracing. Readers will be exposed to latest research frontiers on neuron regulation of metabolism. Key Features Explores the role signaling between neurons plays with respect to metabolism Documents how neurotransmitters affect the regulation of feeding Describes various methods and technologies used to study the neuronal control of metabolism Includes contributions from an international team of leading researchers.

Glial-Neuronal Signaling in Neuroendocrine Systems


Book Description

This volume discusses current research on glial-neuronal interactions in several neuroendocrine systems. Glial-neuronal bidirectional transmission represents one of the fastest-growing areas of investigation in neuroscience today. Unraveling the interactions and signaling synergy between glial cells and neurons is critical to advancing our understanding of brain function. Consequently, this book summarizes the latest findings on the roles of astrocytes, microglia and tanycytes in the control of synaptic transmission, synaptic plasticity, blood-brain signaling, neuroinflammation and immune signaling. In addition, leading experts in the field discuss how reproductive function, the stress response and energy homeostasis are regulated by glial-neuronal communication. Given its scope, the book is essential reading for undergraduate and graduate students in the neurosciences, as well as postdoctoral fellows and established researchers who are looking for a comprehensive overview of glial-neuronal crosstalk in neuroendocrine systems. This is the eleventh volume in the International Neuroendocrine Federation (INF) Masterclass in Neuroendocrinology series (Volumes 1-7 published by Wiley), which aims to illustrate the highest standards and highlight the latest technologies in basic and clinical research, and aspires to provide inspiration for further exploration into the exciting field of neuroendocrinology.




Neural and Metabolic Control of Macronutrient Intake


Book Description

When an excessive proportion of the human energy requirement is derived from fat, the likelihood of obesity increases. Any such individual is at risk for diabetes and cardiovascular disease- grave and costly health hazards. The selective control of fat ingestion is a promising solution to these concerns. Existing data suggests that macronutrient intake can be manipulated. Further research is working to create pharmacological tools that will suppress fat consumption. It will also be possible to fight obesity, heart disease and diabetes. Neural and Metabolic Control of Macronutrient Intake systematically discusses the known physiological mechanisms involved in macronutrientselection, including their molecular, genetic and neurochemical aspects. The book is also a critical review of the hypothesis that ingestion of the three nutrients is regulated by separate neural control mechanisms, leaving open the possibility that strategies could be devised to intervene in bodily control systems and alter the proportion of fat in the diet. This reference provides three types of information: First, the basic background of the biochemical and physiological systems as they relate to macronutrient selection. Second, opinions and data concerning to what degree animals and humans show evidence of macronutrient selection. And, third, evidence about how the central nervous system might be involved in the choices animals make among macronutrients.




Brain Energy Metabolism


Book Description

Brain Energy Metabolism addresses its challenging subject by presenting diverse technologies allowing for the investigation of brain energy metabolism on different levels of complexity. Model systems are discussed, starting from the reductionist approach like primary cell cultures which allow assessing of the properties and functions of a single brain cell type with many different types of analysis, however, at the expense of neglecting the interaction between cell types in the brain. On the other end, analysis in animals and humans in vivo is discussed, maintaining the full complexity of the tissue and the organism but making high demands on the methods of analysis. Written for the popular Neuromethods series, chapters include the kind of detailed description and key implementation advice that aims to support reproducible results in the lab. Meticulous and authoritative, Brain Energy Metabolism provides an ideal guide for researchers interested in brain energy metabolism with the hope of stimulating more research in this exciting and very important field.




The Cerebral Circulation


Book Description

This e-book will review special features of the cerebral circulation and how they contribute to the physiology of the brain. It describes structural and functional properties of the cerebral circulation that are unique to the brain, an organ with high metabolic demands and the need for tight water and ion homeostasis. Autoregulation is pronounced in the brain, with myogenic, metabolic and neurogenic mechanisms contributing to maintain relatively constant blood flow during both increases and decreases in pressure. In addition, unlike peripheral organs where the majority of vascular resistance resides in small arteries and arterioles, large extracranial and intracranial arteries contribute significantly to vascular resistance in the brain. The prominent role of large arteries in cerebrovascular resistance helps maintain blood flow and protect downstream vessels during changes in perfusion pressure. The cerebral endothelium is also unique in that its barrier properties are in some way more like epithelium than endothelium in the periphery. The cerebral endothelium, known as the blood-brain barrier, has specialized tight junctions that do not allow ions to pass freely and has very low hydraulic conductivity and transcellular transport. This special configuration modifies Starling's forces in the brain microcirculation such that ions retained in the vascular lumen oppose water movement due to hydrostatic pressure. Tight water regulation is necessary in the brain because it has limited capacity for expansion within the skull. Increased intracranial pressure due to vasogenic edema can cause severe neurologic complications and death.

Central Regulation of Energy Metabolism With Special Reference To Circadian Rhythm


Book Description

This excellent book describes the roles of the suprachiasmatic nucleus (SCN) of the hypothalamus as a regulatory center of homeostatic mechanism and a circadian oscillator in mammals, including humans. The authors emphasize two important points based on their findings: 1) SCN plays a critical role in central regulation of energy metabolism through which a constant supply of glucose to the central nervous system (CNS) is well maintained; and 2) neurons responsible for the regulation of energy metabolism are located in the ventrolateral part of the SCN and receive retinal neural inputs through both the retinohypothalamic tract and the geniculohypothalamic tract. The authors then discuss the evolutionary importance of these points to the survival of mammals on earth. Other topics examined include the involvement of light in the regulation of neural activity of the autonomic nervous system through the retina and SCN, in addition to the relation of the SCN with regulations of other autonomic nerve functions, such as blood pressure and body temperature. Central Regulation of Energy Metabolism with Special Reference to Circadian Rhythm is important reading for researchers and students in neuroendocrinologists, neurobiologists, biochemists, endocrinologists, physiologists, chronobiologists, psychologists, pharmacologists, and others interested in the topic.
