Book Synopsis Apolipoprotein E and Alzheimer’s Disease by : A.D. Roses
Download or read book Apolipoprotein E and Alzheimer’s Disease written by A.D. Roses and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is now considerable genetic evidence that the type 4 allele of the apolipoprotein E gene is a major susceptibility factor associated with late-onset Alzheimer's disease, the common form of the disease defined as starting after sixty years of age. The role of apolipoprotein E in normal brain metabolism and in the pathogenesis of Alzheimer's disease are new and exciting avenues of research. This book, written by the most outstanding scientists in this new filed, is the first presentation of results concerning the implications of apolipoprotein E on the genetics, cell biology, neuropathology, biochemistry, and therapeutic management of Alzheimer's disease.
Book Synopsis The Role of Apolipoprotein E Concentration and Isoform in Amyloid-[beta] Metabolism in Vivo by : Joseph Michael Castellano
Download or read book The Role of Apolipoprotein E Concentration and Isoform in Amyloid-[beta] Metabolism in Vivo written by Joseph Michael Castellano and published by . This book was released on 2011 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alzheimer's disease is a progressive, neurodegenerative disease characterized by several pathological lesions, one of which is the accumulation of the amyloid-[beta] (A[beta]) peptide into extracellular amyloid plaques. Several autosomal dominant mutations have been shown to cause familial forms of early-onset Alzheimer's disease, but factors that modulate the risk and onset for the more common sporadic, late-onset Alzheimer's disease are less understood. The strongest identified genetic risk factor for sporadic, late-onset Alzheimer's disease is the APOE e4 allele, the presence of which dramatically increases risk and hastens the onset of the disease relative to non-carriers of the allele. Evidence that APOE e4-carriers exhibit accelerated onset of amyloid accumulation has led to the hypothesis that APOE genotype differentially modulates AD risk and onset via regulation of A[beta] metabolism. Thus, we sought to characterize the extent to which modulating the concentration and isoform of apoE regulates brain A[beta] metabolism. To this end, we created transgenic mice overexpressing the low-density lipoprotein receptor (LDLR), a major receptor for apoE in the central nervous system, which led to a significant reduction of brain apoE concentration. After crossing these mice to a mouse model of [beta]-amyloidosis, the resulting mice exhibited a marked reduction in A[beta] deposition. To examine the mechanism by which A[beta] deposition is reduced with increased LDLR expression, we performed in vivo microdialysis in young mice, finding that early decreases in the steady state concentration of A[beta] in the brain interstitial fluid (ISF) could be explained by enhanced A[beta] clearance. To further investigate the mechanism by which LDLR regulates A[beta] metabolism prior to amyloid plaque deposition, we utilized a brain A[beta] efflux method to show that LDLR overexpression increased A[beta] clearance from the brain. To complement this approach, we developed a novel method to directly assess the plasma appearance rate of brain-derived A[beta], which revealed that LDLR overexpression increased brain to blood efflux of A[beta]. We next examined the role of specific apoE isoforms in modulating amyloid accumulation in humans and in a mouse model of [beta]-amyloidosis in which human apoE isoforms were expressed. We found that cerebral A[beta] deposition varied in both humans and in mice in a manner that corresponded to APOE genotype. Using in vivo microdialysis, we found in both young and old mice that the concentration and clearance of A[beta] from the ISF differed according to the isoform of apoE expressed. In vivo stable isotopic labeling kinetics experiments in young mice revealed that fractional synthesis rates of A[beta] did not vary according to human apoE isoform. Moreover, we infused recombinant apoE particles during in vivo microdialysis to demonstrate that intrinsic differences in apoE isoforms contribute to differences in the steady state concentration of ISF A[beta]. Together, these results suggest a mechanism by which APOE alleles modulate AD risk through differential regulation of brain A[beta] clearance. Furthermore, our results suggest that apoE receptors and other molecules involved in A[beta] clearance may represent useful therapeutic targets for AD prevention.
Book Synopsis The Blood-Cerebrospinal Fluid Barrier by : Wei Zheng
Download or read book The Blood-Cerebrospinal Fluid Barrier written by Wei Zheng and published by CRC Press. This book was released on 2005-03-30 with total page 668 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the existence of two barrier systems in the brain, research over the last century has mostly focused on the blood-brain barrier rather than on the blood-CSF barrier. Today, there is a greater understanding of the function of the blood-CSF barrier and of the choroid plexus, a tissue that is the primary site of this barrier. With the growing number of studies that focus on the role of the blood-CSF barrier in CNS homeostasis and neurological disorders, a modern overview of the blood-CSF barrier is long overdue. The Blood-Cerebrospinal Fluid Barrier is exclusively devoted to the blood-CSF barrier. Internationally renowned experts discuss the most recent progress in the field of choroid plexus physiology and update our knowledge of the function of the blood-CSF barrier. The book begins with an overview of the development and morphology of the choroid plexus, and then covers various aspects of its function, such as the regulation of choroidal blood flow, ion transport, and the production and transport of polypeptides. Following an extensive section on the role of the choroid plexus in CNS disorders, the final section discusses in vitro, in vivo, and in situ models of the blood-CSF barrier. This unique book analyzes a wealth of new research on the proven and potential roles of the choroid plexus/blood-CSF barrier in the brain. It is a valuable resource that will foster future studies in neuroscience, pharmacology, and toxicology.

Book Synopsis Magnesium in the Central Nervous System by : Robert Vink
Download or read book Magnesium in the Central Nervous System written by Robert Vink and published by University of Adelaide Press. This book was released on 2011 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: The brain is the most complex organ in our body. Indeed, it is perhaps the most complex structure we have ever encountered in nature. Both structurally and functionally, there are many peculiarities that differentiate the brain from all other organs. The brain is our connection to the world around us and by governing nervous system and higher function, any disturbance induces severe neurological and psychiatric disorders that can have a devastating effect on quality of life. Our understanding of the physiology and biochemistry of the brain has improved dramatically in the last two decades. In particular, the critical role of cations, including magnesium, has become evident, even if incompletely understood at a mechanistic level. The exact role and regulation of magnesium, in particular, remains elusive, largely because intracellular levels are so difficult to routinely quantify. Nonetheless, the importance of magnesium to normal central nervous system activity is self-evident given the complicated homeostatic mechanisms that maintain the concentration of this cation within strict limits essential for normal physiology and metabolism. There is also considerable accumulating evidence to suggest alterations to some brain functions in both normal and pathological conditions may be linked to alterations in local magnesium concentration. This book, containing chapters written by some of the foremost experts in the field of magnesium research, brings together the latest in experimental and clinical magnesium research as it relates to the central nervous system. It offers a complete and updated view of magnesiums involvement in central nervous system function and in so doing, brings together two main pillars of contemporary neuroscience research, namely providing an explanation for the molecular mechanisms involved in brain function, and emphasizing the connections between the molecular changes and behavior. It is the untiring efforts of those magnesium researchers who have dedicated their lives to unraveling the mysteries of magnesiums role in biological systems that has inspired the collation of this volume of work.

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 Pathobiology of Alzheimer's Disease written by and published by Elsevier. This book was released on 1995-10-17 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neuroscience Perspectives provides multidisciplinary reviews of topics in one of the most diverse and rapidly advancing fields in the life sciences.Whether you are a new recruit to neuroscience, or an established expert, look to this series for 'one-stop' sources of the historical, physiological, pharmacological, biochemical, molecular biological and therapeutic aspects of chosen research areas.The last decade has seen tremendous advances in our understanding of the pathobiology of Alzheimer's disease. These will lead to the first generation of drugs aimed at prevention rather than cure. This book covers some of the most important and exciting of these advances, with chapters written by many of the leading researchers in the field.With genetic studies as a backbone to this volume many chapters are devoted to the function and regulation of amyloid b-protein precursor (APP) and apolipoprotein E (ApoE). Other chapters describe cell biological approaches helping to piece together the link between the genetic alterations and the phenotype we call Alzheimer's disease.Although APP and its proteolytic cleavage product, amyloid b-protein, do not answer all the questions, detailed research into this system has undoubtedly increased our knowledge of the pathobiology of AD and has lead to the identification of other risk factors. Understanding the role of ApoE in the pathology of Alzheimer's disease promises to open a whole new field in AD research. * * Reviews the current knowledge of the pathogenesis of Alzheimer's Disease from a clinical perspective to a genetic and cell biological perspective* A comprehensive description of the role of amyloid B-protein precursor in Alzheimer's disease.* Up-to-date research data* Clear illustrations complement the text
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.
Book Synopsis Neurobiology of Mental Illness by : Dennis S. Charney
Download or read book Neurobiology of Mental Illness written by Dennis S. Charney and published by Oxford University Press, USA. This book was released on 2013-07-04 with total page 1259 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our understanding of the neurobiological basis of psychiatric disease has accelerated in the past five years. The fourth edition of Neurobiology of Mental Illness has been completely revamped given these advances and discoveries on the neurobiologic foundations of psychiatry. Like its predecessors the book begins with an overview of the basic science. The emerging technologies in Section 2 have been extensively redone to match the progress in the field including new chapters on the applications of stem cells, optogenetics, and image guided stimulation to our understanding and treatment of psychiatric disorders. Sections' 3 through 8 pertain to the major psychiatric syndromes-the psychoses, mood disorders, anxiety disorders, substance use disorders, dementias, and disorders of childhood-onset. Each of these sections includes our knowledge of their etiology, pathophysiology, and treatment. The final section discusses special topic areas including the neurobiology of sleep, resilience, social attachment, aggression, personality disorders and eating disorders. In all, there are 32 new chapters in this volume including unique insights on DSM-5, the Research Domain Criteria (RDoC) from NIMH, and a perspective on the continuing challenges of diagnosis given what we know of the brain and the mechanisms pertaining to mental illness. This book provides information from numerous levels of analysis including molecular biology and genetics, cellular physiology, neuroanatomy, neuropharmacology, epidemiology, and behavior. In doing so it translates information from the basic laboratory to the clinical laboratory and finally to clinical treatment. No other book distills the basic science and underpinnings of mental disorders and explains the clinical significance to the scope and breadth of this classic text. The result is an excellent and cutting-edge resource for psychiatric residents, psychiatric researchers and doctoral students in neurochemistry and the neurosciences.
