Download or read book Glial Cell Function Paperback written by Bernardo Castellano and published by Gulf Professional Publishing. This book was released on 2003-09-15 with total page 790 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although knowledge of the development and differentiation of glial cells has significantly increased in recent years, there are still many questions unanswered. The first section of the book is devoted to this very active topic and includes contributions on Schwann cells, oligodendrocytes, astroglia and microglia. The second section of the book covers cellular interactions, the role they play on myelination and remyelination, how these interactions take place and the molecules involved. The third section of this volume focuses on the interactions of neurons with glial cells and their role in brain function. Neuron-glia cross talk appears to be fundamental for synaptic transmission and several chapters in this section address this topic. The topic of how glial cells react to brain injury and how they participate in neuroprotection and brain repair is covered in section four of this book. As our knowledge about the molecules involved in the regenerative properties of glia increases, new avenues are open for the use of genetically modified glia with therapeutic purposes. The final section of the book is devoted to therapeutic approaches to tumours, viral and prion infections. Gene therapy is a promising approach for the treatment of gliomas, one of the most devastating forms of cancer. A chapter on prion diseases and microglia addresses a question of tremendous actuality, since prion diseases in cows is at this moment the major veterinary problem in Europe and has created a considerable social alarm.
Download or read book Myelin written by Bernard Zalc and published by Oxford University Press. This book was released on 2018-08-22 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: The emergence of myelin 425 million years ago marked a turning point in evolution. Consider for a moment the invention of insulated wire, which allows for the transmission of electrical current. Functioning in a similar way, the membrane surrounding nerve fibers, or myelin, enables the remarkable acceleration of nerve impulses. Surprisingly, myelin occupies nearly half the volume of the human brain and is critical for our intellectual and motor performance. Without myelin, our thoughts and our movements would suffer overwhelming delays. We owe our reflexes to myelin: it is what makes us brake when a child dashes out onto the road, or snatch away a hand absent-mindedly placed on a burning hot stove. When damaged, myelin can lead to irreversible disability, cognitive decline, and sensory impairments. The study of myelin's role in the conduction of nerve impulses has led to a better understanding of several diseases including multiple sclerosis, Guillain-Barre syndrome, Charcot disease (ALS), and Niemann-Pick disease.

Available in PDF, EPUB and Kindle. Book excerpt: Despite everything that has been written about the brain, a very important part of this vital organ has been overlooked in most books -- until now. The Other Brain is the story of glia, which make up approximately 85 percent of the cells in the brain. Long neglected as little more than cerebral packing material ("glia" means glue), glia are sparking a revolution in brain science. Glia are completely different from neurons, the brain cells that we are familiar with. Scientists are discovering that glia have their own communication network, which operates in parallel to the more familiar communication among neurons. Glia provide the insulation for the neurons, and glia even regulate the flow of information between neurons. But it is the potential breakthroughs for medical science that are the most exciting frontier in glia research today. Diseases such as brain cancer and multiple sclerosis are caused by diseased glia. Glia are now believed to play an important role in such psychiatric illnesses as schizophrenia and depression, and in neurodegenerative diseases such as Parkinson's and Alzheimer's. They are linked to infectious diseases such as HIV and prion disease (mad cow disease, for example) and to chronic pain. Scientists have discovered that glia repair the brain and spinal cord after injury and stroke. The more we learn about these cells that make up the "other" brain, the more important they seem to be. Written by a neuroscientist who is a leader in the research to reveal the secrets of these brain cells, The Other Brain offers a firsthand account of science in action. It takes us into the laboratories where important discoveries are being made, and it explains how scientists are learning that glial cells come in different types, with different capabilities. It tells the story of glia research from its origins to the most recent discoveries and gives readers a much more complete understanding of how the brain works and where the next breakthroughs in brain science and medicine are likely to come.

This book was released on 2012-12-06 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is remarkable that each month the quantity ofarticles published on AIDS still that address numbers in the thousands. The basic, clinical and sociological aspects this epidemic have been vigorously investigated, and equally as extensively reported in traditional as well as new journals. Therefore, what can the reader ofthis volume expect to find that is different from the information already found in the literature? The authors of this text met in October 1993 to discuss not only AIDS and its effects on the nervous system but also to address the problem from the point of view of the diverse technologies that are used in understanding the disease. Just as the recog nition ofoncogenic viruses gave us insights into cellular genes that govern growth, the study ofHIV-I in the nervous system has opened new areas ofinvestigation in the nervous system. Use of human fetal and glioma-derived cell cultures, discovery of toxins in the nervous system, release and damage of cytokines in the brain, the neuropathic effects of HIV proteins, the investigation of new treatment for neuro AIDS, and virus detection strategies to identify latent HIVI infection are described in this volume. Basic and clinical investigators from more than thirty laboratories around the world contributed to the ideas discussed at the meeting, "Technical Advances in AIDS Research in the Human Nervous System.
Download or read book Mesenchymal Epithelial Interactions in Neural Development written by Joachim R. Wolff and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is based on the NATO Advanced Research Workshop on "Mesenchymal-Epithelial Interactions in Neural Development" which was held in Berlin during March 1986. The idea that it may be the time for this workshop arose from a discussion among the organizers who met at a conference in Innsbruck. During the twenties, Spemann demonstrated that, in vertebrates, the formation of neuroepithelium depends on the induction by specific mesodermal derivatives. This was about the first time that mesenchymal-epithelial interactions had been recognized as an important mechanism in the development of an epithelial organ. Since then two things had become clear: 1) The identity and role of molecules, elaborated at mesenchymal-neuroepithelial interfaces had been partially elucidated in spinal cord and peripheral nerve ontogeny but, until recently, had been ignored in studies on the development of the brain. 2) In many-non-neural epithelia, the surrounding mesenchyme regulates such fundamental developmental steps as, for example, cell proliferation, morphogenesis and cell differentia tion, and there is no reason to exclude similar influences and interactions from brain development. It seemed to us that the importance and implications of many of these findings had not been appreciated by many developmental neurobiologists and that an attempt should be made to initiate discussions and exchange of ideas among different groups of scientists involved in extracellular matrix (ECM) research. This turned out to be a formidable task because of the great diversity of disciplines contributing findings to this active field.
Download or read book The Role of Glia in Neurotoxicity written by Michael Aschner and published by CRC Press. This book was released on 1996-03-27 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is well established that glial cells represent more than mere passive cytoskeletal support elements of the central and peripheral nervous system. A reciprocal relationship exists between neurons and glia that is vital for mutual differentiation, development, and functioning of both cell types. It also has become apparent that perturbations in glial function may lead to deleterious consequences in juxtaposed neurons. It is therefore possible that neuronal damage induced by chemicals or neuropathic disease involves dissociation of glial-neuronal interactions. The Role of Glia in Neurotoxicity brings together experts in the neurosciences to provide a more complete understanding of the effects of chemicals on nervous system function. This book explores potential sites of glial-neuronal interactions both in the central and peripheral nervous system, focusing on potential sites of neurotoxicant actions. Text introduces basic aspects of neuroscience, the first step toward understanding the mechanisms at work in normal physiology. The ways in which these processes are disturbed in pathological conditions are discussed. Distinguished authors examine the functional interactions between glial cells and neurons during development, adulthood, and senescence. The roles of glia in the normal CNS and PNS are described. The book offers specific, in-depth examples of directly (via diffusive and cell surface signals) or indirectly (via effects on the extracellular fluid or the blood-brain barrier) mediated glial neurotoxicity. This reference includes different techniques, conceptual frameworks, and approaches that are currently used in the study of the role of glia in neurotoxicity. This timely review not only presents an excellent overview of the state of the science but also provides direction for future research into the consequences of an altered glial-neuronal unit.

Book excerpt: Recent physiologic investigations have shown that the deep cerebellar nuclei may play an important role in the initiation and monitoring of skilled move ments. Much of this physiologic work has been carried out in the absence of a secure foundation in neuroanatomical information. Although the main sources of the afferent fibers and the major terminations of the efferent fibers related to these nuclei have been known for many years, remarkably little information about the organization of the nuclei themselves has been collected. The kinds of nerve cells, their arrangement within the nuclei, the patterns of their dendritic arborizations, the distribution of incoming fibers among the neurons, the relationship between the outgoing nerve fibers and the nerve cells from which they originate - these and many other morphologic features were either unknown or only superficially explored. In fact, so little was known about the deep cerebellar nuclei when I began to work on this subject that the investigations reported here are virtually without antecedents, a refreshing change from the cerebellar cortex which has been repeatedly and exhaustively surveyed. My studies on the cerebellar nuclei began in the spring of 1972. They were initiated with the intent of applying the principles of analysis that had been developed for the cerebellar cortex to a different but related part of the brain.

Download or read book The Autobiography of a Transgender Scientist written by Ben Barres and published by MIT Press. This book was released on 2018-10-30 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: A leading scientist describes his life, his gender transition, his scientific work, and his advocacy for gender equality in science. Ben Barres was known for his groundbreaking scientific work and for his groundbreaking advocacy for gender equality in science. In this book, completed shortly before his death from pancreatic cancer in December 2017, Barres (born in 1954) describes a life full of remarkable accomplishments—from his childhood as a precocious math and science whiz to his experiences as a female student at MIT in the 1970s to his female-to-male transition in his forties, to his scientific work and role as teacher and mentor at Stanford. Barres recounts his early life—his interest in science, first manifested as a fascination with the mad scientist in Superman; his academic successes; and his gender confusion. Barres felt even as a very young child that he was assigned the wrong gender. After years of being acutely uncomfortable in his own skin, Barres transitioned from female to male. He reports he felt nothing but relief on becoming his true self. He was proud to be a role model for transgender scientists. As an undergraduate at MIT, Barres experienced discrimination, but it was after transitioning that he realized how differently male and female scientists are treated. He became an advocate for gender equality in science, and later in life responded pointedly to Larry Summers's speculation that women were innately unsuited to be scientists. Privileged white men, Barres writes, “miss the basic point that in the face of negative stereotyping, talented women will not be recognized.” At Stanford, Barres made important discoveries about glia, the most numerous cells in the brain, and he describes some of his work. “The most rewarding part of his job,” however, was mentoring young scientists. That, and his advocacy for women and transgender scientists, ensures his legacy.

Download or read book Enteric Glia written by Brian D. Gulbransen and published by Biota Publishing. This book was released on 2014-07-01 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: The enteric nervous system (ENS) is a complex neural network embedded in the gut wall that orchestrates the reflex behaviors of the intestine. The ENS is often referred to as the “little brain” in the gut because the ENS is more similar in size, complexity and autonomy to the central nervous system (CNS) than other components of the autonomic nervous system. Like the brain, the ENS is composed of neurons that are surrounded by glial cells. Enteric glia are a unique type of peripheral glia that are similar to astrocytes of the CNS. Yet enteric glial cells also differ from astrocytes in many important ways. The roles of enteric glial cell populations in the gut are beginning to come to light and recent evidence implicates enteric glia in almost every aspect of gastrointestinal physiology and pathophysiology. However, elucidating the exact mechanisms by which enteric glia influence gastrointestinal physiology and identifying how those roles are altered during gastrointestinal pathophysiology remain areas of intense research. The purpose of this e-book is to provide an introduction to enteric glial cells and to act as a resource for ongoing studies on this fascinating population of glia. Table of Contents: Introduction / A Historical Perspective on Enteric Glia / Enteric Glia: The Astroglia of the Gut / Molecular Composition of Enteric Glia / Development of Enteric Glia / Functional Roles of Enteric Glia / Enteric Glia and Disease Processes in the Gut / Concluding Remarks / References / Author Biography
Download or read book Retinal Glia written by Andreas Reichenbach and published by Biota Publishing. This book was released on 2015-02-01 with total page 666 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1851, Heinrich Müller discovered what he called “radial fibers” and what we now call Müller cells, as the principal glial cells of the vertebrate retina. Later on, other glial cell types were found in the retina, including astrocytes, microglia, and even oligodendrocytes. It turned out that retinal glial cells are essential constituents of the tissue. For instance, Müller cells appear to constitute the “core” of columnar units of clonally and functionally related groups of neurons. Their primary function is to support neuronal functioning by guiding the light towards the photoreceptor cells, removing excess neurotransmitter molecules from extracellular space, and performing efficient clearance of excess extracellular potassium ions. The latter two functions are also crucial for neuronal survival and are coupled to water clearance which is also essential. Müller cells are capable of “sensing” neuronal activity and modifying it by the release of signal substances (gliotransmitters). In cases of retinal injuries the Müller cells become reactive, and all above-mentioned functions are impaired. However, such de-differentiated Müller cells may proliferate, and may even serve as stem cells for the regeneration of a damaged retina. As well as the Müller cells, retinal astrocytes and microglial cells are important players in retinal development and function. This book gives a comprehensive survey of the present knowledge on retinal glia.
