Book Synopsis Signaling Proteins in Alzheimer's Disease by : Gerin Rachel Stevens
Download or read book Signaling Proteins in Alzheimer's Disease written by Gerin Rachel Stevens and published by . This book was released on 1998 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Collectively, these data demonstrate the presence of paxillin in CNS neurons and tissues in a distribution resembling focal contacts. Since focal contacts are an intracellular relay site for signals from the ECM, it is possible that paxillin has a role in translating these chemical signals into downstream mechanical changes in neurons via a PKC-independent mechanism.

A 2D-electrophoretic map of human brain proteins including Down Syndrome brain protein expression established by in-gel-digestion of spots with subsequent MALDI-identification provides the scientific basis for protein work to the neuroscientist. Altogether, the book provides a series of new candidate genes possibly involved in Down Syndrome neurobiology, tools for neuroscience studies on Down Syndrome brain thus serving as a manual and updated views and aspects on Down Syndrome pathobiology.
Download or read book Tau oligomers written by Jesus Avila and published by Frontiers E-books. This book was released on 2014-08-18 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neurofibrillary tangles (NFTs) composed of intracellular aggregates of tau protein are a key neuropathological feature of Alzheimer’s Disease (AD) and other neurodegenerative diseases, collectively termed tauopathies. The abundance of NFTs has been reported to correlate positively with the severity of cognitive impairment in AD. However, accumulating evidences derived from studies of experimental models have identified that NFTs themselves may not be neurotoxic. Now, many of tau researchers are seeking a “toxic” form of tau protein. Moreover, it was suggested that a “toxic” tau was capable to seed aggregation of native tau protein and to propagate in a prion-like manner. However, the exact neurotoxic tau species remain unclear. Because mature tangles seem to be non-toxic component, “tau oligomers” as the candidate of “toxic” tau have been investigated for more than one decade. In this topic, we will discuss our consensus of “tau oligomers” because the term of “tau oligomers” [e.g. dimer (disulfide bond-dependent or independent), multimer (more than dimer), granular (definition by EM or AFM) and maybe small filamentous aggregates] has been used by each researchers definition. From a biochemical point of view, tau protein has several unique characteristics such as natively unfolded conformation, thermo-stability, acid-stability, and capability of post-translational modifications. Although tau protein research has been continued for a long time, we are still missing the mechanisms of NFT formation. It is unclear how the conversion is occurred from natively unfolded protein to abnormally mis-folded protein. It remains unknown how tau protein can be formed filaments [e.g. paired helical filament (PHF), straight filament and twisted filament] in cells albeit in vitro studies confirmed tau self-assembly by several inducing factors. Researchers are still debating whether tau oligomerization is primary event rather than tau phosphorylation in the tau pathogenesis. Inhibition of either tau phosphorylation or aggregation has been investigated for the prevention of tauopathies, however, it will make an irrelevant result if we don’t know an exact target of neurotoxicity. It is a time to have a consensus of definition, terminology and methodology for the identification of “tau oligomers”.
Download or read book Neuronal Cytoskeleton written by Hirokawa and published by CRC Press. This book was released on 1994-01-12 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the primary functions of microtubule-associated proteins (MAPs) such as MAP2 and tau in neuronal morphogenesis, as well as relationships between neuronal differentiation and the expression of neuronal intermediate filaments (nestin, alpha internexin, and neurofilament triplet proteins). It emphasizes the importance of several cytoskeletal proteins for neuronal differentiation and morphogenesis, organelle transport, and synaptic functions. The book considers the involvement of tau MAPs in the formation of paired helical filaments in Alzheimer's disease, and it examines the mechanisms of organelle transports and molecular motors such as kinesin, braindynein, and kinesin superfamily proteins. Cytoskeletal proteins involved in synaptic formation and transmitter release and new synaptic junctional-associated proteins are explored as well.

Book Synopsis Alzheimer's Disease: Cellular and Molecular Aspects of Amyloid beta by : J. Robin Harris
Download or read book Alzheimer's Disease: Cellular and Molecular Aspects of Amyloid beta written by J. Robin Harris and published by Springer Science & Business Media. This book was released on 2006-11-22 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: To understand Alzheimer's disease (AD) is one of the major thrusts of present-day clinical research, strongly supported by more fimdamental cellular, biochemical, immunological and structural studies. It is these latter that receive attention within this book. This compilation of 20 chapters indicates the diversity of work currently in progress and summarizes the current state of knowledge. Experienced authors who are scientifically active in their fields of study have been selected as contributors to this book, in an attempt to present a reasonably complete survey of the field. Inevitably, some exciting topics for one reason or another have not been included, for which we can only apologize. Standardization of terminology is often a problem in science, not least in the Alzheimer field; editorial effort has been made to achieve standardization between the Chapters, but some minor yet acceptable personal / author variation is still present, i. e. P-amyloid/amyloid-P; Ap42/Apl-42/APi. 42! The book commences with a broad survey of the contribution that the range of available microscopical techniques has made to the study of Alzheimer's amyloid plaques and amyloid fibrillogenesis. This chapter also serves as an Introduction to the book, since several of the topics introduced here are expanded upon in later chapters. Also, it is significant to the presence of this chapter that the initial discovery of brain plaques, by Alois Alzheimer, utilized light microscopy, a technique that continues to be extremely valuable in present-day AD research.

Book Synopsis Immunoreceptor Signaling by : L. E. Samelson
Download or read book Immunoreceptor Signaling written by L. E. Samelson and published by Cold Spring Harbor Perspective. This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The behavior of lymphocytes in the immune system depends on encounters with antigens. These bind to immunoreceptors on the surface of T-cells and B-cells, activating a variety of signal transduction pathways that control cell survival, proliferation, differentiation, and effector functions. Written and edited by experts in the field, this collection from Cold Spring Harbor Perspectives in Biology includes contributions covering the structures of the T-cell and B-cell immunoreceptors, the numerous kinases and adaptors that associate with their intracellular tails, and the downstream signaling pathways that lead to transcription of interleukins and other outputs. Other contributions examine the roles of other receptors, co-stimulatory signals, and innate immune responses in regulation of immunoreceptor signaling. The spatial organization of the immunological synapses connecting lymphocytes and antigen-presenting cells is also discussed, along with the role of the cytoskeleton in immunoreceptor function. Computational models of the signaling processes complete the volume, making it essential reading for systems biologists as well as all immunologists and cell biologists interested in understanding how lymphocytes function.
Book Synopsis Neuroprotective Signal Transduction by : Mark P. Mattson
Download or read book Neuroprotective Signal Transduction written by Mark P. Mattson and published by Springer Science & Business Media. This book was released on 1997-10-10 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Neuroprotective Signal Transduction prominent researchers and clinicians focus on how inter- and intracellular signaling mechanisms prevent the degeneration and death of neurons occurring in both acute and chronic neurodegenerative disorders. Authoritative contributions dissect the signaling pathways of an array of neuroprotective factors-ranging from neurotrophins (NGF, BDNF, NT-3, and NT-4/5), to growth factors (bFGF, IGF-1, GDNF), to cytokines (TNF, IL-1b, and TGFb), to secreted amyloid precursor proteins, to protease nexin-1. Also treated are cytoprotective signaling events that occur within injured neurons independently of intercellular signals. Neuroprotective Signal Transduction presents fundamental, cutting-edge treatment of the cellular and molecular signal transduction pathways found in human neurodegenerative conditions. The book's elucidation of the molecular cascades evolved by the nervous system to protect itself is now lead to effective strategies for preventing neuronal degeneration in such conditions as stroke, traumatic brain injury, Alzheimer's disease, Parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis, and will form the basis for powerful new drug discovery and gene therapy strategies.

Book Synopsis Two Faces of Evil: Cancer and Neurodegeneration by : Thomas Curran
Download or read book Two Faces of Evil: Cancer and Neurodegeneration written by Thomas Curran and published by Springer Science & Business Media. This book was released on 2010-12-16 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: Homeostasis involves a delicate interplay between generative and degenerative processes to maintain a stable internal environment. In biological systems, equilibrium is established and controlled through a series of negative feedback mechanisms driven by a range of signal transduction processes. Failures in these complex communication pathways result in instability leading to disease. Cancer represents a state of imbalance caused by an excess of cell proliferation. In contrast, neurodegeneration is a consequence of excessive cell loss in the nervous system. Both of these disorders exhort profound tolls on humanity and they have been subject to a great deal of research designed to ameliorate this suffering. For the most part, the topics have been viewed as distinct and rarely do opportunities arise for transdisciplinary discussions among experts in both fields. However, cancer and neurodegeneration represent yin-yang counterpoints in the regulation of cell growth, and it is reasonable to hypothesize that key regulatory events mediated by oncogenes and tumor suppressor genes in cancer may also affect neurodegenerative processes
Book Synopsis Quality Control of Cellular Protein in Neurodegenerative Disorders by : Uddin, Md. Sahab
Download or read book Quality Control of Cellular Protein in Neurodegenerative Disorders written by Uddin, Md. Sahab and published by IGI Global. This book was released on 2020-02-14 with total page 515 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protein misfolding and aggregation are hallmarks of several neurodegenerative proteinopathies. Though multiple factors like aging, oxidative stress, mitochondrial dysfunction, proteotoxic insults, genetic inconsistency, etc. are responsible for the dysfunction of the neuronal protein quality control system, targeting protein quality control has become an auspicious approach to halt the propagation of neurodegeneration. Quality Control of Cellular Protein in Neurodegenerative Disorders provides diverse aspects exploring the role of the protein quality control in neurodegenerative disorders and potential therapeutic strategies to combat the development and propagation of neurodegeneration. Featuring coverage on a broad range of topics such as molecular chaperones, protein misfolding, and stress signaling, this book is ideally designed for neurobiologists, neuropsychologists, neurophysiologists, medical professionals, neuropathologists, researchers, academicians, students, and practitioners engaged in studies of the protein quality control system in neuronal cells.
Download or read book Tau Biology written by Akihiko Takashima and published by Springer Nature. This book was released on 2020-02-24 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents essential studies and cutting-edge research results on tau, which is attracting increasing interest as a target for the treatment of Alzheimer's disease. Tau is well known as a microtubule-associated protein that is predominantly localized in the axons of neurons. In various forms of brain disease, neuronal loss occurs, with deposition of hyperphosphorylated tau in the remaining neurons. Important questions remain regarding the way in which tau forms hyperphosphorylated and fibrillar deposits in neurons, and whether tau aggregation represents the toxic pathway leading to neuronal death. With the help of new technologies, researchers are now solving these long-standing questions. In this book, readers will find the latest expert knowledge on all aspects of tau biology, including the structure and role of the tau molecule, tau localization and function, the pathology, drivers, and markers of tauopathies, tau aggregation, and treatments targeting tau. Tau Biology will be an invaluable source of information and fresh ideas for those involved in the development of more effective therapies and for all who seek a better understanding of the biology of the aging brain.
Book Synopsis Neurological Functions of the Masterswitch Protein Kinase – GSK-3 by : Oksana Kaidanovich-Beilin
Download or read book Neurological Functions of the Masterswitch Protein Kinase – GSK-3 written by Oksana Kaidanovich-Beilin and published by Frontiers E-books. This book was released on with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The functions of the brain that allow us to think, feel, move, and perceive the world are the result of an exchange of information within a network composed of millions of specialized cells called neurons and glia. Neurons use neurotransmitters and other extracellular messengers to communicate with each other, and to constantly update and re-organize their network of connections in a process known as neural plasticity. In order to respond to these extracellular signals, neurons are equipped with specialized receptors that can recognize a single neurotransmitter a bit like a lock would recognize a key. They do this by activating or inhibiting a class of specialized signaling proteins and second messengers. Typically, signaling proteins are themselves organized in networks or pathways in which they activate or inhibit each other in order to integrate the mass of information received by a single cell and to regulate the biological functions of this cell. As we can see, rather than simply being a network of neurons, the brain can be seen as a sort of “Russian doll” in which each neuron is at the same time a part of networks with other neurons and the receptacle of many networks composed of signaling proteins. Two individual genes encode two paralogous signaling proteins: Glycogen Synthase Kinase -3 alpha and beta (GSK-3a, GSK-3b), named for its ability to phosphorylate a key metabolic enzyme of glycogen synthesis, glycogen synthase. This unique “glamour and gloom” protein kinase, has been intriguing many researches for over 30 years by its unusual features, still unknown mechanisms of its activation, its regulation by multiple “key” intracellular pathways, and its capacity to influence the functions of many substrates. Since GSK-3 was discovered, there has been significant progress in elucidating its regulatory roles in the neuron and the structure and functions of the brain. Lithium has been used as a gold standard in the treatment of bipolar disorder for 60 years; and “GSK-3’s renaissance” in psychiatry began with the discovery of GSK-3 as lithium's intracellular target. Since then, GSK3 has been implicated in the pathogenesis of mood disorders, schizophrenia, Alzheimer’s disease, ADHD, multiple sclerosis, Fragile X syndrome and Huntington disease. Connections to these and other diseases has led over the last 10 years to the generation of multiple types of GSK-3 inhibitors as promising therapeutic treatments for the aforementioned pathological conditions. During last couple years new genetic models have been generated, including conventional and conditional mouse models, allowing the discovery of new roles of GSK-3 in the mechanism of neurotransmitter action, neurodevelopment, learning and memory formation, GSK-3’s gene - effect on mouse behavior, and other functions. Thus, GSK-3 has been well-established as an intracellular second messenger for several neurotransmitter systems, and as an important therapeutic target of mood stabilizers, antipsychotics and psychomimetic drugs. The proposed Specific Topic for Frontiers in Neuroscience will be focused on the latest advances from leading laboratories in this area, subdivided into 5 topics: (1) GSK-3 history, mechanism of regulation, substrate specificity and comparison between the brain function of two GSK-3 genes through new animal models and cell biology approaches; (2) role of GSK-3 in neurodevelopment and neuronal structure; (3) involvement of GSK-3 in synaptic functions, learning and memory, and in serotonin and dopamine pathways; (4) role of GSK-3 in neuroinflammation, and application to the pathogenesis of multiple sclerosis, AD, schizophrenia, Fragile X, brain tumors, stroke and bipolar disorder; (5) development of GSK-3 inhibitors and their application in psychiatry, including special discussion about the mechanism of lithium action.
Book Synopsis Neurodegeneration and Alzheimer's Disease by : Ralph N. Martins
Download or read book Neurodegeneration and Alzheimer's Disease written by Ralph N. Martins and published by John Wiley & Sons. This book was released on 2019-07-10 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the impact of diet, exercise, genetics, and hormones on the risk and development of Alzheimer’s and other neurogenerative diseases Diet is widely known to impact on neurological function. Nevertheless, academic texts discussing this relationship are relatively few in number. This book therefore fills an important gap in the current literature. Opening with an overview of neurodegenerative diseases, particularly Alzheimer’s disease, the text then focuses on explaining the means by which glycemic control and lipid metabolism – and associated nutritional and lifestyle variables – may factor into such disorders’ prevention and treatment. An international group of experts in the fields of food science and neurodegeneration have contributed chapters that examine Alzheimer’s disease within a broad range of contexts. Offering dietary, genetic, and hormonal perspectives, the authors explore topics ranging from sugar consumption to digestive fermentation, and Alzheimer’s disease animal models to the cognition-enhancing effects of physical exercise. Also included are overviews of the latest research into current and developing methods of treatment and diagnosis, as well as differential diagnostics. This groundbreaking book: Explores how glucose metabolism, insulin resistance, lipid metabolism, and high intake of refined carbohydrates are linked to Alzheimer's disease Discusses how genetic makeup can impact risk of Alzheimer’s and Parkinson’s disease Examines cognitive changes in neurodegeneration, lists current tests for determining cognitive impairment, and provides information concerning differential diagnosis Discusses potential advantages of increasing antioxidant and micronutrient intake Reviews hormonal influences on neurodegeneration Examines the links between protein intake and Alzheimer’s disease. Neurodegeneration and Alzheimer's Disease is an essential resource for researchers, medical practitioners, dietitians, and students with an interest in neurological diseases and their diagnosis and risk factors, as well as diet-related conditions such as diabetes and obesity. Lifestyle and diet influence neurodegeneration risk, and a better understanding of this evidence amongst health professionals will hopefully lead to greater public awareness of how to reduce the likelihood of these widespread conditions.
