This book was released on 2008-06-25 with total page 801 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new Springer volume, which comes complete with a free DVD, is a comprehensive and detailed overview of the synapse with emphasis on the glutamatergic synapse. Most chapters relate the synapse’s functional aspects to its molecular mechanisms. This approach shows which mechanisms are characterized on both the functional and structural level and can thus be considered firmly established. It’s an important text for neuroscientists and disease-oriented clinicians in neurology.

Download or read book Regulation of Synaptic Structure and Function at the Drosophila Neuromuscular Junction written by Aline Dorret Blunk and published by . This book was released on 2013 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neuronal communication requires a spatially organized synaptic apparatus to coordinate neurotransmitter release from synaptic vesicles and activation of postsynaptic receptors. Structural remodeling of synaptic connections can strengthen neuronal communication and synaptic efficacy during development and behavioral plasticity. Here, I describe experimental approaches that have revealed how the actin cytoskeleton participates in transynaptic signaling to control synapse assembly. I also describe my studies on how regulation of endocytic trafficking controls synaptic growth during neuronal development. To identify regulators of synapse assembly, I carried out a large-scale EMS mutagenesis screen of the second chromosome. From this screen I identified a mutation in actin 57B that disrupts synaptic morphology and presynaptic active zone organization. Actin 57B is one of six actin genes in Drosophila and is expressed in body wall muscle during larval development. The isolated allele harbors a point mutation disrupting a highly conserved amino acid present throughout the actin family. Homozygous mutant larvae show impaired alignment and spacing of presynaptic active zones. Additionally, disruption of the organization of the postsynaptic density is observed, with mislocalization of the Spectrin cytoskeleton and the PSD-homolog Disc-Large. Phallodin staining reveals a severe disruption of postsynaptic actin surrounding presynaptic boutons, with the formation of aberrant large actin swirls. Based on these results, we hypothesize that the loss of a synaptic interaction mediated by actin 57B leads to disruption of postsynaptic cytoskeletal organization and dysregulation of signals required to organize presynaptic active zones. Additionally, I present data that provide new insights into the mechanisms controlling synaptic growth signaling during transit through the endocytic pathway. Nervous Wreck (Nwk) is a presynaptic F-BAR/SH3 protein that regulates synaptic growth signaling in Drosophila. Here, I show that Nwk acts through a physical interaction with Sorting Nexin 16 (SNX16). SNX16 promotes synaptic growth signaling by activated BMP receptors, and live imaging in neurons reveals that SNX16-positive early endosomes undergo transient interactions with Nwkcontaining recycling endosomes. We identify an alternative signal termination pathway in the absence of Snx16 that is controlled by ESCRT-mediated internalization of receptors into the endosomal lumen. Our results define a presynaptic trafficking pathway mediated by SNX116, NWK and the ESCRT complex that functions to control synaptic growth signaling at the interface between endosomal compartments. Together, these experiments have expanded our understanding of the molecular mechanisms that control synaptic growth and assembly, highlighting the role of the postsynaptic actin cytoskeleton and the presynaptic endosomal trafficking pathway as key regulators.

Download or read book The Synapse written by Virginia M. Pickel and published by Elsevier. This book was released on 2013-11-16 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Synapse summarizes recent advances in cellular and molecular mechanisms of synaptic transmission and provides new insights into neuronal plasticity and the cellular basis of neurological diseases. Part 1 provides an in-depth look at structural differences and distribution of various pre- and post-synaptic proteins found at glutamatergic synapses. Part 2 is dedicated to dendritic spines and their associated perisynaptic glia, which together constitute the tripartite synapse. The spines are portrayed as major sites for calcium sequestration and local protein synthesis. Part 3 highlights the important regional and cellular differences between glutamatergic transmission and that of neurotransmitters such as dopamine and acetylcholine that are commonly found in axon terminals without synaptic membrane specializations. Part 4 provides an overview of the synapse from the time of formation to degeneration under the powerful influence of aging or hormonal decline that leads to severe deficits in cognitive function. Each chapter is illustrated with drawings and images derived from calcium imaging, electron microscopic immunolabeling, or electrophysiology. This book is a valuable reference for neuroscientists and clinical neurologists in both research and clinical settings. A comprehensive reference focused on the structure and function of the synapse Covers the links between the synapse and neural plasticity and the cellular basis of neurologic disease Detailed coverage of dendritic spines and associated perisynaptic glia—the tripartite synapse Includes in-depth coverage of synapse degeneration due to aging or hormonal decline related to severe cognitive impairment

Book excerpt: This open access book describes marked advances in imaging technology that have enabled the visualization of phenomena in ways formerly believed to be completelyimpossible. These technologies have made major contributions to the elucidation of the pathology of diseases as well as to their diagnosis and therapy. The volume presents various studies from molecular imaging to clinical imaging. It also focuses on innovative, creative, advanced research that gives full play to imaging technology inthe broad sense, while exploring cross-disciplinary areas in which individual research fields interact and pursuing the development of new techniques where they fuse together. The book is separated into three parts, the first of which addresses the topic of visualizing and controlling molecules for life. Th e second part is devoted to imaging of disease mechanisms, while the final part comprises studies on the application of imaging technologies to diagnosis and therapy. Th e book contains the proceedings of the 12th Uehara International Symposium 2017, “Make Life Visible” sponsored by the Uehara Memorial Foundation and held from June 12 to 14, 2017. It is written by leading scientists in the field and is an open access publication under a CC BY 4.0 license.

Available in PDF, EPUB and Kindle. Book excerpt: Brain aminergic pathways are organized in parallel and interacting systems, which support a range of functions, from homoeostatic regulations to cognitive, and motivational processes. Despite overlapping functional influences, dopamine, serotonin, noradrenaline and histamine systems provide different contributions to these processes. The histaminergic system, long ignored as a major regulator of the sleep-wake cycle, has now been fully acknowledged also as a major coordinator of attention, learning and memory, decision making. Although histaminergic neurons project widely to the whole brain, they are functionally heterogeneous, a feature which may provide the substrate for differential regulation, in a region-specific manner, of other neurotransmitter systems. Neurochemical preclinical studies have clearly shown that histamine interacts and modulates the release of neurotransmitters that are recognized as major modulators of cognitive processing and motivated behaviours. As a consequence, the histamine system has been proposed as a therapeutic target to treat sleep-wake disorders and cognitive dysfunctions that accompany neurodegenerative and neuroinflammatory pathologies. Last decades have witnessed an unexpected explosion of interest in brain histamine system, as new receptors have been discovered and selective ligands synthesised. Nevertheless, the complete picture of the histamine systems fine-tuning and its orchestration with other pathways remains rather elusive. This Research Topic is intended to offer an inter-disciplinary forum that will improve our current understanding of the role of brain histamine and provide the fundamentals necessary to drive innovation in clinical practice and to improve the management and treatment of neurological disorders.
