This book was released on 2012-12-06 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: The neuronal cytoskeleton is a complex structure responsive to both intrinsic and extrinsic factors. Defined populations of neurons in the brains of patients with Alzheimer and several other neurodegenerative diseases contain abnormal filamentous accumulations which share elements with the cytoskeleton. Although there is a general consensus that these abnormal filaments do contain cytoskeletal elements, much debate remains regarding which cytoskeletal elements are incorporated and whether the cytoskeletal rearrangement is primary or secondary to other cellular changes. In this book these questions are addressed in a historical perspect ive in light of new data that allows the reinterpretation of previously reported results. Contributions are based on many of the major tech niques of modern biology including biochemistry, molecular biology, electron microscopy and immunocytochemistry. In the view of the editor, this volume is being written at a time when our understanding of the cytopathology of Alzheimer disease is moving from predominantly descriptive to both analytical and mechanistic. I hope that this contribution will provide impetus to speed this transi tion.

Available in PDF, EPUB and Kindle. Book excerpt: Epidemiological studies, modern clinical, neuroimaging, neuropsychological, molecular biological, and genetic studies have considerably enhanced our knowledge about ageing processes of the human brain, its sequelae, diagnostic, and therapeutic possibilities and limits. In addition to Alzheimer's disease and other degenerative dementias, the impact of cerebrovascular lesions and their risk factors in the pathogenesis of cognitive disorders of the aged are increasingly acknowledged, and the recognition of mild cognitive impairment as a frequent initial stage of developing dementia is becoming an increasingly important diagnostic and therapeutic problem. The included papers were presented at the 7th International Symposium in Graz, Sept. 2001 and give a timely overview of the current and future concepts of pathogenesis, diagnosis, and treatment strategies of pathological brain ageing and dementias, early recognition of mild cognitive impairment and future possiblities of prevention of dementing processes.
Download or read book Protein Aggregation and Fibrillogenesis in Cerebral and Systemic Amyloid Disease written by J. Robin Harris and published by Springer. This book was released on 2012-12-06 with total page 650 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume of the Subcellular Biochemistry series is the result of the long-standing research interest of the editor in the molecular mechanism underlying Alzheimer’s disease and other amyloid diseases, indicated also by the earlier book in the series (Volume 38), devoted to Alzheimer’s disease. The broad coverage within the present amyloidogenesis book represents an attempt to collate current knowledge relating to the proteins and peptides involved in most of the known amyloid diseases, together with some amyloid/fibril-forming proteins and peptides that are not involved in diseases. Thus, the range of topics included is comprehensive and furthermore it was thought appropriate to include both basic science and clinical presentation of the subjects under discussion.
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.

Available in PDF, EPUB and Kindle. Book excerpt: The past decade has witnessed a revolution in the attempts of scientists to under stand the molecular basis of dementia. Although dementia, as defined by global cogni tive decline involving gradual loss of memory, reasoning, judgment, and orientation, presents most commonly in the form of Alzheimer's disease (AD), an assortment of other less common disorders, such as prion and Pick's disease, can also lead to symp toms that are similar to those observed in patients with AD. The primary goal of Molecular Mechanisms of Dementia is to address the various mechanisms and multi faceted approaches currently being employed to more clearly delineate the etiological and pathogenic events responsible for the onset of dementia. Perhaps the greatest boon to obtaining a clearer understanding of the causes of AD has come from genetic and molecular biological studies carried out over the past decade. At the genetic level, it has become increasingly clear that AD is a heteroge neous disorder that can be broadly classified into two categories. "Late onset" (>60 yr) cases, which account for the vast majority of AD, genetically involve "susceptibility" genes representing risk factors for the disease (e. g. , inheritance of the 84 allele of the Apolipoprotein E gene). In many cases, the susceptibility gene can act as a "modifier" that modulates the pathogenic cascade occurring subsequent to a separate etiological event "initiating" or "causing" the disorder.

This book was released on 2013-06-29 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: As human longevity continues to be extended, so will the impact of age-associated dementia on individual lives and society. Alzheimer’s disease as the most common cause of dementia in the elderly remains a sentinal problem and its underlying pathology is still poorly understood. Available therapeutic strategies require considerable refinement and the development of new therapeutic strategies need input from basic research. Thus continued efforts are necessary both to understand basic mechanisms of the condition and to achieve more powerfull therapies. This volume brings together the reports of basic scientists and clinical investigators. The chapters provide a spectrum of information valuable for clinicians and scientists. This issue bridges the gap between laboratory work in basic science and the development of urgently needed therapeutic strategies. Areas presented are the molecular and cellular biology of the disease, pathogenetic mechanisms and potential therapeutic targets, genetics, risk factors, strategies of prevention and treatment as well as practical aspects of medical and social care for patients with Alzheimer’s disease.

This book was released on 2012-12-06 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: There has been a tremendous increase in interest in the neuropathogenicity of viruses during the past decade as we have come to recognize that the human immunodeficiency virus, which causes the acquired immunodeficiency syndrome (AIDS), can infect glial cells and cause neurological disease. Yet this increase has not been limited to AIDS but has extended to viruses that infect either or both the central and peripheral nervous systems. The changes examined here include both neurological and psychological diseases or syndromes. Moreover, the chapters in this volume review the interaction of the host immune system with the viruses examined and how such interactions may increase or decrease the neuropatho genicity of the viruses. Questions regarding viral neuropathogenesis include: (I) What is the mode of transmission of virus to the nervous system? (2) What types of cells are infected, and do they contain receptors for the virus? (3) What is the extent of damage that results from viral infection? (4) What are the immunologic mecha nisms by which damage is mediated or limited? Many of these questions remain unanswered, but this volume delves into efforts to provide some answers.

Available in PDF, EPUB and Kindle. Book excerpt: Dementia is a major health problem that becomes increasingly common with advancing age. Despite recent progress in neurobiology and molecular genetics, the aetiology and pathogenesis of most dementia disorders are still poorly understood, and early exact diagnosis as a prerequisite of effective treatment needs to be improved. The present volume includes the contributions of renowned experts in the field of neurodegeneration presented at the International Symposium "Ageing and Dementia 1999”, September 24–26, 1999 at Graz. It focusses on genetics, epidemiology, new neuroimaging techniques, and the role of vascular, immunological and other mechanisms including oxidative stress and estrogens in the development of neurodegeneration and dementia. Recent developments in diagnosis and therapy of Alzheimer disease and related disorders are reviewed and future therapeutic approaches are discussed. Thus, this volume provides a timely overview of most recent developments in dementia research and treatment strategies of dementia disorders.
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 Mechanisms of Neuroinflammation written by Gonzalo Emiliano Aranda Abreu and published by BoD – Books on Demand. This book was released on 2017-08-23 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Mechanisms of Neuroinflammation" book explains how the neuronal cells become swollen at the moment of the blood-brain barrier disruption and how they lose their immunological isolation. A cascade of cytokines and immune cells from the bloodstream enters the nervous system, inflaming neurons and activating the glia. This produces a neuroinflammatory process that can generate different neurodegenerative diseases. Better understanding of mechanisms that are activated at the time when the damage to the brain occurs could lead to the development of suitable therapies that revert the neuronal inflammation and thus prevent further damage to the nervous system.
