Book excerpt: Understanding the mechanisms that underlie brain activity and function remains one of the major frontiers of biology. All the processes of how we co-ordinate our movements, sense our surroundings, react to stimuli and learn and retain information rely on complicated networks of neurons thatcommunicate with each other and their targets. This fast and accurate intercellular signalling most occurs at synapses, specialized processes of neurons that release chemical signals, called neurotransmitters. Neurotransmitters: Frontiers in Molecular Biology will provide the reader withextensive background information on neurotransmitter release. It takes a multidisciplinary approach, but does not assume previous knowledge having basic introductions to most topics. Topics however are covered in enough detail to be of interest to experts in the field. Throughout, emphasis is placedon the rationale by which proteins are assigned specific functions rather than just providing facts about function. The first chapter provides an introduction to the basic features and properties of the synapse and is followed by a chapter detailing several important techniques used to elucidatevarious aspects of release. Chapters 3 describes many of the biochemical approaches used to identify proteins involved in neurotransmitter release and then chapters 4 and 5 focus on more specific aspects of synaptic transmission: the proteins that transport neurotransmitters and the role ofphosphlipids in the process. The next five chapters concentrate on approaches to unravel the function of many proteins in vivo by using toxins, giant squid axons, C. elegans, Drosophila, and mice. The final chapter summarizes current knowledge on endocytosis and recycling. Knowledge of themolecular mechanisms underlying neurotransmitter release has expanded tremendously over the last 10 years. Many of the proteins involved have been isolated, but their roles have yet to be determined. These discoveries will be a major challenge and it is therefore the major aim of this book not onlyto provide information but also to generate excitement.

Download or read book Molecular Mechanisms in Visual Transduction written by D.G. Stavenga and published by Elsevier. This book was released on 2000-11-30 with total page 596 pages. Available in PDF, EPUB and Kindle. Book excerpt: Molecular mechanisms in visual transduction is presently one of the most intensely studied areas in the field of signal transduction research in biological cells. Because the sense of vision plays a primary role in animal biology, and thus has been subject to long evolutionary development, the molecular and cellular mechanisms underlying vision have a high degree of sensitivity and versatility. The aims of visual transduction research are first to determine which molecules participate, and then to understand how they act in concert to produce the exquisite electrical responses of the photoreceptor cells. Since the 1940s [1] we have known that rod vision begins with the capture of a quantum of energy, a photon, by a visual pigment molecule, rhodopsin. As the function of photon absorption is to convert the visual pigment molecule into a G-protein activating state, the structural details of the visual pigments must be explained from the perspective of their role in activating their specific G-proteins. Thus, Chapters 1-3 of this Handbook extensively cover the physico-chemical molecular characteristics of the vertebrate rhodopsins. Following photoconversion and G-protein activation, the phototransduction cascade leads to modifications of the population of closed and open ion channels in the photoreceptor plasma membrane, and thereby to the electrical response. The nature of the channels of vertebrate photoreceptors is examined in Chapter 4, and Chapter 5 integrates the present body of knowledge of the activation steps in the cascade into a quantitative framework. Once the phototransduction cascade is activated, it must be subsequently silenced. The various molecular mechanisms participating in inactivation are treated in Chapters 1-4 and especially Chapter 5. Molecular biology is now an indispensable tool in signal transduction studies. Numerous vertebrate (Chapter 6) and invertebrate (Chapter 7) visual pigments have been characterized and cloned. The genetics and evolutionary aspects of this great subfamily of G-protein activating receptors are intriguing as they present a natural probe for the intimate relationship between structure and function of the visual pigments. Understanding the spectral characteristics from the molecular composition can be expected to

Available in PDF, EPUB and Kindle. Book excerpt: This book offers comprehensive coverage of the most important areas in photoreceptors and light signalling. Photoreceptors enable most species to sense not only the presence of light but also the information, such as irradiance, colour or spectral distribution, direction and polarization of light. They are vital, therefore, in providing organisms with energy and information about their surroundings, such as day and night cycles. This book covers the range of photoreceptors that have been discovered to date and the broad range of methods used when researching how they operate, including: action spectroscopy; methods for protein purification; the whole range of molecular biological and genetic methods; and numerous spectroscopic methods, from absorption and fluorescence spectroscopy to X-ray diffraction, used for solving the structure of photoreceptors. Written by leading experts in the field, Photoreceptors and Light Signalling provides the reader with the most recent results and research. This book will be valued by a wide-range of readers, including students of photochemistry, photobiology, biology, chemistry and physics and other professionals in academia.

Download or read book Vertebrate Photoreceptors written by Takahisa Furukawa and published by Springer Science & Business Media. This book was released on 2014-04-15 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a series of comprehensive views on various important aspects of vertebrate photoreceptors. The vertebrate retina is a tissue that provides unique experimental advantages to neuroscientists. Photoreceptor neurons are abundant in this tissue and they are readily identifiable and easily isolated. These features make them an outstanding model for studying neuronal mechanisms of signal transduction, adaptation, synaptic transmission, development, differentiation, diseases and regeneration. Thanks to recent advances in genetic analysis, it also is possible to link biochemical and physiological investigations to understand the molecular mechanisms of vertebrate photoreceptors within a functioning retina in a living animal. Photoreceptors are the most deeply studied sensory receptor cells, but readers will find that many important questions remain. We still do not know how photoreceptors, visual pigments and their signaling pathways evolved, how they were generated and how they are maintained. This book will make clear what is known and what is not known. The chapters are selected from fields of studies that have contributed to a broad understanding of the birth, development, structure, function and death of photoreceptor neurons. The underlying common word in all of the chapters that is used to describe these mechanisms is “molecule”. Only with this word can we understand how these highly specific neurons function and survive. It is challenging for even the foremost researchers to cover all aspects of the subject. Understanding photoreceptors from several different points of view that share a molecular perspective will provide readers with a useful interdisciplinary perspective.
Download or read book Signal Transduction written by Bastien D. Gomperts and published by Gulf Professional Publishing. This book was released on 2003-10-15 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: Signal Transduction is a text reference on cellular signalling processes. Starting with the basics, it explains how cells respond to external cues (hormones, cytokines, neurotransmitters, adhesion molecules, extracellular matrix etc), and shows how these inputs are integrated and co-ordinated. The first half of the book provides the conceptual framework, explaining the formation and action of second messengers, particularly cyclic nucleotides and calcium, and the mediation of signal pathways by GTP-binding proteins. The remaining chapters deal with the formation of complex signalling cascades employed by cytokines and adhesion molecules, starting at the membrane and ending in the nucleus, there to regulate gene transcription. In this context, growth is an important potential outcome and this has relevance to the cellular transformations that underlie cancer. The book ends with a description at the molecular level of how signalling proteins interact with their environment and with each other through their structural domains. Each main topic is introduced with a historical essay, detailing the sources, key observations and experiments that set the scene for recent and current work.
