Download or read book Neurodegeneration written by Dennis Dickson and published by John Wiley & Sons. This book was released on 2011-09-09 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most textbooks on neurodegenerative disorders have used a classification scheme based upon either clinical syndromes or anatomical distribution of the pathology. In contrast, this book looks to the future and uses a classification based upon molecular mechanisms, rather than clinical or anatomical boundaries. Major advances in molecular genetics and the application of biochemical and immunocytochemical techniques to neurodegenerative disorders have generated this new approach. Throughout most of the current volume, diseases are clustered according to the proteins that accumulate within cells (e.g. tau, α-synuclein and TDP-43) and in the extracellular compartments (e.g. β-amyloid and prion proteins) or according to a shared pathogenetic mechanism, such as trinucleotide repeats, that are a feature of specific genetic disorders. Chapters throughout the book conform to a standard lay-out for ease of access by the reader and are written by a panel of International Experts Since the first edition of this book, major advances have been made in the discovery of common molecular mechanisms between many neurodegenerative diseases most notably in the frontotemporal lobar degenerations (FTLD) and motor neuron disease or amyotrophic lateral sclerosis. This book will be essential reading for clinicians, neuropathologists and basic neuroscientists who require the firm up-to-date knowledge of mechanisms, diagnostic pathology and genetics of Neurodegenerative diseases that is required for progress in therapy and management.
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 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.

Download or read book The Genetic Basis Of Neurodegenerative Diseases written by Wei-Hua Chang and published by . This book was released on 2015 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neurodegenerative diseases, such as Alzheimer's disease (AD) and Parkinson's disease (PD), are characterized by the selective loss of subsets of neurons in the central nervous system (CNS). While increasing evidence suggests a combination of both genetic and environmental factors as the cause of both AD and PD, the molecular etiology underlying the pathogenesis of these diseases remains largely unknown. The gene Suppressor enhancer lin-12 1-Like (SEL1L) is widely known to encode an endoplasmic reticulum (ER) membrane protein and is highly expressed in CNS neurons. To investigate the potential association between neurodegeneration and dysfunction of SEL1L, we generated and characterized mice with a neuron-specific knockout of SEL1L (Sel1l-NKO). Sel1l-NKO mice have an average lifespan of 8-10 weeks and show significant growth retardation. These mice progressively developed motor dysfunction, manifested by abnormal limb clasping, impaired gross and fine motor coordination, and loss of body strength. In addition, Sel1l-NKO mice exhibited broad deficits in spatial memory and learning. Immunohistological analysis revealed a perturbed dendritic network in the cerebral cortex. Cultured SEL1L-deficient primary neurons of the cerebral cortex displayed impaired dendritic growth. Furthermore, Fluoro-Jade C staining revealed an increased number of degenerating neurons in Sel1l-NKO mice. Altogether, these behavioral and cellular defects indicate that SEL1L deficiency results in neurological disorders. The molecular mechanism behind these neurological disorders is unclear. We therefore investigated the protein expression pattern of the Sel1l-NKO brain to identify the mechanistic alternation in the absence of SEL1L. The results show that SEL1L deficiency induced disruption of ER homeostasis and activated the unfolded protein response (UPR), an adaptive response to misfolded protein aggregation. Unexpectedly, we found elevated levels of phosphorylated microtubule tau protein (p-tau), a pathological characteristic of many neurodegenerative diseases. Our data suggest that a brachial downstream gene of UPR, c-Jun N-terminal kinases (JNK), might be the major tau kinase that induces tau phosphorylation in Sel1l-NKO mice. To further investigate the role of UPR in these neurological disorders, an inhibitor of the eIF2alpha kinase (PERK) branch of the UPR was administrated to Sel1l-NKO mice, which slightly improved their motor function performance. Collectively, our data suggest that dysfunction of SEL1L, via sustained UPR and tau pathology, induces neurotoxicity. ii.

This book was released on 2016-12-28 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: Autophagy: Cancer, Other Pathologies, Inflammation, Immunity, Infection, and Aging is an eleven volume series that discusses in detail all aspects of autophagy machinery in the context of health, cancer, and other pathologies. Autophagy maintains homeostasis during starvation or stress conditions by balancing the synthesis of cellular components and their deregulation by autophagy. This series discusses the characterization of autophagosome-enriched vaccines and its efficacy in cancer immunotherapy. Autophagy serves to maintain healthy cells, tissues, and organs, but also promotes cancer survival and growth of established tumors. Impaired or deregulated autophagy can also contribute to disease pathogenesis. Understanding the importance and necessity of the role of autophagy in health and disease is vital for the studies of cancer, aging, neurodegeneration, immunology, and infectious diseases. Comprehensive and forward-thinking, these books offer a valuable guide to cellular processes while also inciting researchers to explore their potentially important connections. Presents the most advanced information regarding the role of the autophagic system in life and death Examines whether autophagy acts fundamentally as a cell survivor or cell death pathway or both Introduces new, more effective therapeutic strategies in the development of targeted drugs and programmed cell death, providing information that will aid in preventing detrimental inflammation Features recent advancements in the molecular mechanisms underlying a large number of genetic and epigenetic diseases and abnormalities, including atherosclerosis and CNS tumors, and their development and treatment Includes chapters authored by leaders in the field around the globe—the broadest, most expert coverage available
Download or read book Cyclin Dependent Kinase 5 Cdk5 written by Nancy Y. Ip and published by Springer Science & Business Media. This book was released on 2009-02-28 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cyclin Dependent Kinase 5 provides a comprehensive and up-to-date collection of reviews on the discovery, signaling mechanisms and functions of Cdk5, as well as the potential implication of Cdk5 in the treatment of neurodegenerative diseases. Since the identification of this unique member of the Cdk family, Cdk5 has emerged as one of the most important signal transduction mediators in the development, maintenance and fine-tuning of neuronal functions and networking. Further studies have revealed that Cdk5 is also associated with the regulation of neuronal survival during both developmental stages and in neurodegenerative diseases. These observations indicate that precise control of Cdk5 is essential for the regulation of neuronal survival. The pivotal role Cdk5 appears to play in both the regulation of neuronal survival and synaptic functions thus raises the interesting possibility that Cdk5 inhibitors may serve as therapeutic treatment for a number of neurodegenerative diseases.

Download or read book Molecular Neurobiology of Alzheimer Disease and Related Disorders written by Masatoshi Takeda and published by Karger Medical and Scientific Publishers. This book was released on 2004 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alzheimers disease affects 6-10% of the elderly population, causing impairment in cognitive functions and significant disability in daily living for more than ten years. Neurofibrillary tangles, amyloid deposits and neuronal loss are the three hallmarks of Alzheimers disease. Due to insolubility of these unique structures in Alzheimer brain tissue, they were very difficult to study by usual biochemical methods in the past. Active research is now going on to elucidate the pathogenesis of Alzheimers disease. Major topics of neurobiological study of Alzheimers disease include the unraveling of the molecular mechanism of neurofibrillary tangle formation in neuronal and glial cells, the molecular processing of amyloid precursor protein in intracellular organella and in extra-cellular space, and the molecular mechanism of neuronal loss. The articles in this book were selected from contributions presented by leading scientists in this field at the international symposium which took place in Osaka in 2002. This publication is essential reading for all researchers, clinicians, basic and social scientists, neurologists and psychiatrists to promote the understanding of this formidable disease.
