Consequences of Intracellular Amyloid in Alzheimer’s Disease addresses one of the more currently unresolved aspects confounding Alzheimer’s research, the significance of intraneuronal amyloid. It seeks to explain some of the unresolved questions concerning intracellular amyloid and its origin, entry, and toxicity. Following up on Dr. D’Andrea’s first book, Bursting Neurons and Fading Memories: An Alternative Hypothesis for the Pathogenesis of Alzheimer’s Disease, this book further examines the Inside-Out or Bursting alternative hypothesis of how amyloid escapes the circulatory system to ultimately enter neurons, also examining whether there is a relationship between intracellular amyloid, amyloid plaques, and cognitive impairment. Through a comprehensive explanation of the currently relevant scientific research on intracellular amyloid compiled in this handy reference, readers will better understand the mechanisms that lead to neuron death. Presents the latest research on the significance of intracellular amyloid as it relates to Alzheimer’s Addresses crucial questions about intracellular amyloid, including how if forms and enters neurons, its toxicity, if it triggers cell death, and how amyloid plaques are formed Examines the potential relationship between intracellular amyloid, plaques, and cognitive impairment in an effort to answer whether Alzheimer’s is initially a problem of amyloid, the neuron, or of the blood-brain barrier Seeks to help researchers generate additional alternative therapeutic opportunities to cure Alzheimer’s

Strong evidence continues to accumulate indicating that amyloid-beta (Aß) is a central part of Alzheimer’s disease (AD) pathogenesis in spite of the negative evidence coming from failed clinical trials. Therefore, mechanisms of clearance of Aß are of great interest in understanding AD pathogenesis and the development of effective treatments. This topic focuses on the issues related to Aß clearance in AD. The topics covered include proteases that degrade Aß and their localization, regulation, and functions. This topic also covers issues related to clearance through uptake by glia and through low-density lipoprotein (LDL) receptor mediated mechanisms. Signal transduction related to AD pathology and clearance is also addressed. Finally, immunotherapy and other novel therapeutic approaches are discussed.

The subject of aluminium and Alzheimer's disease has been plagued with controversy. This controversy has served to obscure much of the scientific research in this field, and subsequently has obscured the possibility that aluminium is a contributory factor in the aetiology of Alzheimer's disease. This book brings together many of the world's leading scientists researching aluminium and life and contains their critical summaries on the known facts about aluminium toxicity in man and to offer an opinion on the implications of this knowledge on a link between aluminium and Alzheimer's disease. The subject areas of the chapters were chosen to reflect the myriad of ways that aluminium is known to impact upon mammalian physiology and function and range from clinical studies, through animal models of disease to the detailed biochemistry of aluminium toxicity. Chapters are also included on epidemiology and other factors involved in the aetiology of Alzheimer's. This is the first time that this subject has been treated in such a comprehensive manner. The research detailed in each chapter, includes the latest research in the field, it has been critically appraised and this appraisal has been used by each author to present an informed opinion of its relevance to aluminium and Alzheimer's disease. The chapters are much more than reviews; they are a statement of the state of the art and of what the future may hold for research in this field. As a whole they show the high quality of research that has been carried out in our efforts to understand the toxicity of aluminium in man and that we are far away from discounting the possibility that aluminium is a contributory factor in the aetiology of Alzheimer's disease.

Calcium is vital for human physiology; it mediates multiple signaling cascades, critical for cell survival, differentiation, or death both as first and as second messenger. The role of calcium as first messenger is mediated by the G-protein coupled receptor, the extracellular calcium-sensing receptor (CaSR). The CaSR is a multifaceted molecule that senses changes in the concentration of a wide variety of environmental factors including di- and trivalent cations, amino acids, polyamines, and pH. In calcitropic tissues with obvious roles in calcium homeostasis such as parathyroid, kidney, and bone it regulates circulating calcium concentrations. The germline mutations of the CaSR cause parathyroid disorders demonstrating the importance of the CaSR for the maintenance of serum calcium homeostasis. The CaSR has an important role also in a range of non-calcitropic tissues, such as the intestine, lungs, central and peripheral nervous system, breast, skin and reproductive system, where it regulates molecular and cellular processes such as gene expression, proliferation, differentiation and apoptosis; as well as regulating hormone secretion and lactation. This Research Topic is an overview of the CaSR and its molecular signaling properties together with the various organ systems where it plays an important role. The articles highlight the current knowledge regarding many aspects of the calcitropic and non-calcitropic physiology and pathophysiology of the CaSR.

Advances in Alzheimer’s disease (AD) research have been challenging and without major breakthroughs in understanding its pathological basis. The reigning hypothesis suggests AD is the result of extracellular amyloid deposition that seed to form amyloid plaques, which then grow and kill neighboring neurons. However, there are several inconsistencies with this hypothesis, not to mention the inability to show clinical benefit in several failed clinical trials by pharmaceuticals (i.e., from Pfizer, Eli Lilly, etc.), and it is in the field’s best interest to explore and test multiple hypotheses for pathology rather than drive the majority of research on this single amyloid theory. Reviewing many scientifically peer-reviewed publications, this book describes the "Inside-Out" hypothesis on how amyloid escapes the circulatory system through a dysfunctional blood-brain barrier to bind to the alpha 7 nicotinic acetylcholine receptor on pyramidal neurons. Over time, excessive amounts of amyloid appear to be internalized, resulting in neuron death and lysis. This simple mechanism readily explains plaque composition, size, shape, and location. Based on the current direction of research in the field, this hypothesis appears years from any research and development. The clear, compelling, and unifying "Inside-Out" hypothesis of AD is brought to life through a string of scientific publications, synthesizing many known features of disease pathology A high-level text on AD pathology, and suggestions for progress in a stagnating field Point-by-point discussion on the issues surrounding the current amyloid cascade, and possible reasons why current clinical trials have failed Contains high-quality photomicrographs in support of the "Inside-Out" hypothesis using single, double, and triple immunohistochemistry on human AD CNS tissues Chapters address the need for a unifying plaque nomenclature, the importance of intracellular amyloid, the blood-brain barrier, inflammation, and autoimmunity

Cerebral amyloid angiopathy (CAA) is a distinctive abnormality of small cerebral blood vessels, one that has intrigued neuroscientists for decades. The time seems right for a book which examines the phenomenon of CAA using a multifaceted approach: What does it produce clinically? How might CAA be imaged? What are the crucial biochemical/cellular events within cerebral vessel walls that lead to CAA? How can in vitro or transgenic experimental systems be used to understand the etiology of, or even potential treatments for, CAA? The editors have assembled key figures in the field of CAA research to examine these (and other) questions in a series of focused chapters that address specific issues of importance in understanding CAA and its clinical manifestations. Comprehending the biology and pathogenesis of this fascinating vascular lesion may even provide clues to less common forms of cerebral microvascular disease that have been recognized for decades (hypertensive microangiopathy) or more recently (CADASIL).
