Download or read book Molecular Mechanisms of Neurotransmitter Release written by Zhao-Wen Wang and published by Springer Science & Business Media. This book was released on 2010-11-16 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neurons in the nervous system organize into complex networks and their functions are precisely controlled. The most important means for neurons to communicate with each other is transmission through chemical synapses, where the release of neurotransmitters by the presynaptic nerve terminal of one neuron influences the function of a second neuron. Since the discovery of chemical neurotransmission by Otto Loewi in the 1920s, great progress has been made in our understanding of mol- ular mechanisms of neurotransmitter release. The last decade has seen an explosion of knowledge in this field. The aim of Molecular Mechanisms of Neurotransmitter Release is to provide up-to-date, in-depth coverage of essentially all major mole- lar mechanisms of neurotransmitter release. The contributors have made great efforts to write concisely but with sufficient background information, and to use figures/diagrams to present clearly key concepts or experiments. It is hoped that this book may serve as a learning tool for neuroscience students, a solid reference for neuroscientists, and a source of knowledge for people who have a general interest in neuroscience. I was fortunate to be able to gather contributions from a group of outstanding scientists. I thank them for their efforts. In particular, I want to thank Dr. Erik Jorgensen who offered valuable suggestions about the book in addition to contrib- ing an excellent chapter. I thank US National Science Foundation and National Institute of Health for their supports.
Download or read book Molecular Mechanisms of Ca2 dependent Neuropeptide Secretion written by and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The human brain contains billions of brain cells (neurons). Neurons communicate with each other through the release of signalling molecules. Of these molecules, neurotransmitters are best-known. Neurotransmitter release is very fast, less than 1/50th of a second. Aside from this fast communication, neurons also release slow signalling molecules: neuropeptides. Neuropeptides regulate numerous processes in the brain. They dampen hyperactivity during an epileptic seizure, let neurons grow in response to physical activity, and can be released in the blood stream to regulate blood pressure, or trigger start the birth of a child. Release of neuropeptides is accurately regulated by neurons. Neuropeptides are packaged in vesicles, surrounded by a lipid membrane. The vesicles contain many neuropeptide molecules, which gives the vesicle a dark core under the microscope. Therefore, neuropeptide vesicles are called ‘dense-core vesicles’ (DCVs). Neurons release neuropeptides when the calcium concentration in the cell is high. This happens when the neuron is activated: channels in the cell membrane open, resulting in calcium influx. Calcium triggers the fusion of vesicles with the outer membrane of the neuron, the plasma membrane. Ca2+ sensors can bind Ca2+ + and fuse membranes of dense-core vesicles with the neuronal plasma membrane. Now, neuropeptides can diffuse out of the vesicle and fulfil their signalling function. This thesis describes which calcium sensors regulate the fusion of dense-core vesicles with the plasma membrane, which allows for the release of neuropeptides. Chapter 1 provides a general introduction on the topic. Chapter 2 describes that two calcium sensors, Synaptotagmin-1 (Syt1) and Synaptotamin-7 (Syt7), are required for the fusion of dense-core vesicles. Both Syt1 and Syt7 are required for fusion, because DCV fusion is strongly reduced in absence of these sensors.

Download or read book Calcium Entry Channels in Non Excitable Cells written by Juliusz Ashot Kozak and published by CRC Press. This book was released on 2017-07-14 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: Calcium Entry Channels in Non-Excitable Cells focuses on methods of investigating the structure and function of non-voltage gated calcium channels. Each chapter presents important discoveries in calcium entry pathways, specifically dealing with the molecular identification of store-operated calcium channels which were reviewed by earlier volumes in the Methods in Signal Transduction series. Crystallographic and pharmacological approaches to the study of calcium channels of epithelial cells are also discussed. Calcium ion is a messenger in most cell types. Whereas voltage gated calcium channels have been studied extensively, the non-voltage gated calcium entry channel genes have only been identified relatively recently. The book will fill this important niche.
Download or read book Clostridial Neurotoxins written by Cesare Montecucco and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tetanus has been known from the very beginning of medical literature since it was first described by Hyppocrates of Cos in the fifth century B.C. For 24 centuries it was considered a neuro logical disease until the breakthrough of CARLE and RATIONE (1884) who demonstrated its infectious etiology. Following the establishment of purified cultures of Clostridium tetani(KITASATO 1889), FABER (1890), and TIZZONI and CATIANI (1890) demon strated that the disease is actually an intoxication caused by a proteic neurotoxin. This toxin was shown by BRUSHCHETIINI (1892) to move retroaxonally and to act at the spinal cord level. Soon thereafter VAN ERMENGEN (1897) demonstrated that botu lism is also due to intoxication with a protein toxin produced by bacteria of the genus Clostridium. These bacteria and their spores and ubiquitous, and the majority of them do not produce neurotoxins. The selective advantage of producing such potent toxin is still a matter of speculation (see Popoff, this volume). The next major advance was the discovery that tetanus neurotoxin 1 can be converted by formaldehyde treatment to a nonpathogenic but still fully immunogenic form, and that this can be used successfully as a vaccine to prevent tetanus (RAMON and DESCOMBEY 1925). Similar vaccines (toxoids) can be prepared with botulism neurotoxins (see MiDDLEBROOK and BROWN, this volume). The prevention oftetanus by vaccination (see Galatzka and Gasse, this volume) is one of the great successes of basic research coupled with an efficient public medicine service.
