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.

Neurochemistry is a flourishing academic field that contributes to our understanding of molecular, cellular and medical neurobiology. As a scientific discipline, neurochemistry studies the role of chemicals that build the nervous system, it explores the function of neurons and glial cells in health and disease, it discovers aspects of cell metabolism and neurotransmission, and it reveals how degenerative processes are at work in the nervous system. Accordingly, this book contains chapters from a variety of topics that fall into the following broad sections: I. Neural Membranes and Intracellular Signaling, II. Neural Processing and Intercellular Signaling, III. Growth, Development and Differentiation, and IV. Neurodegenerative Diseases. The book presents comprehensive reviews in these different areas written by experts in their respective fields. Neurodegeneration and neuronal diseases are featured prominently and are a recurring theme throughout most chapters. This book will be a most valuable resource for neurochemists and other scientists alike. In addition, it will contribute to the training of current and future neurochemists and, hopefully, will lead us on the path to curing some of the biggest challenges in human health.

The extracellular matrix (ECM) is the focus of much interest in biology and bioengineering. Increasing understanding of the influence of the ECM on cell behaviour has led to the exciting possibilities of tissue engineering. Aside from new therapeutic tools, understanding the ECM is of course fundamental to basic cell biology research. Mimicking the Extracellular Matrix approaches this topic from both basic science and practical engineering perspectives. Seven topics are approached each in a pair of chapters, one with a biological approach and its partner with a bioengineering approach. Topics include the mechanical properties of the ECM, which outlines current knowledge of the ECM physical structure and reviewing state-of-the-art strategies to mimic its native microenvironments. The organisational characteristics of the ECM form the focus of another pair of chapters, where the collagen triple helix is discussed, followed by a review of advances in artificial reproduction of well-ordered systems using self-assembling peptides, or peptide amphiphiles. The balanced approach of this text gives it a broad appeal to those interested in the ECM from a range of backgrounds and disciplines. Suitable for undergraduates, postgraduates, and academics, this text aims to unify the current knowledge of ECM biology and matrix-mimicking biomaterials.

The amyloid precursor protein APP plays a key role in the pathogenesis of Alzheimer’s disease (AD), as proteolytical cleavage of APP gives rise to the Aβ peptide which is deposited in the brains of Alzheimer patients. Despite this, our knowledge of the normal cell biological and physiological functions of APP and the closely related APLPs is limited. This may have hampered our understanding of AD, since evidence has accumulated that not only the production of the Aβ peptide but also the loss of APP-mediated functions may contribute to AD pathogenesis. Thus, it appears timely and highly relevant to elucidate the functions of the APP gene family from the molecular level to their role in the intact organism, i.e. in the context of nervous system development, synapse formation and adult synapse function, as well as neural homeostasis and aging. Why is our understanding of the APP functions so limited? APP and the APLPs are multifunctional proteins that undergo complex proteolytical processing. They give rise to an almost bewildering array of different fragments that may each subserve specific functions. While Aβ is aggregation prone and neurotoxic, the large secreted ectodomain APPsα - produced in the non-amyloidogenic α-secretase pathway - has been shown to be neurotrophic, neuroprotective and relevant for synaptic plasticity, learning and memory. Recently, novel APP cleavage pathways and enzymes have been discovered that have gained much attention not only with respect to AD but also regarding their role in normal brain physiology. In addition to the various cleavage products, there is also solid evidence that APP family proteins mediate important functions as transmembrane cell surface molecules, most notably in synaptic adhesion and cell surface signaling. Elucidating in more detail the molecular mechanisms underlying these divers functions thus calls for an interdisciplinary approach ranging from the structural level to the analysis in model organisms. Thus, in this research topic of Frontiers we compile reviews and original studies, covering our current knowledge of the physiological functions of this intriguing and medically important protein family.

Almost four decades of innovative and intensive research on Alzheimer’s disease (AD) have brought major advances in our understanding of its pathogenesis, improved tools for diagnosis, and strategies for its treatment. This research has helped build a solid foundation of knowledge in the neurosciences and biological basis of AD and AD-related neurological disorders. Scientific background and insightful hypotheses are of major relevance in order to approach to an effective therapy for this devastating disease. Current Hypotheses and Research Milestones in Alzheimer's Disease contains 20 seminal chapters by authors with varying views on the neuroanatomical, neuropathological, neuropsychological, neurological, and molecular aspects of AD. These chapters grew out of “Current Hypothesis on Alzheimer’s Disease”, held in Viña del Mar, Chile, in November of 2007. Participants included the world’s leading Alzheimer’s researchers, whose work has illuminated AD investigations during the past few decades. Students, academics and medical professionals will find this text an invaluable addition to the study of this important subject.

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.

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

This book represents the third in a series of International Conferences related to Alzheimer's (AD) and Parkinson's (PD) diseases. The first one took place in Eilat, Israel, in 1985; and the second one in Kyoto, Japan, in 1989. This book contains the full text of oral and poster presentations from the Third International Conference on Alzheimer's and Parkinson's Diseases: Recent Developments, held in Chicago, Illinois, U.S.A. on November 1-6, 1993. The Chicago Conference was attended by 270 participants. The Scientific Program was divided into nine oral sessions, a keynote presentation, and a poster session. The conference culminated in a Round Table Discussion involving all of the participants in the conference. The four and one-half day meeting served as an excellent medium for surveying the current status of clinical and preclinical developments in AD and PD. There were 59 oral presentations and 93 posters. This book incorporates a majority of both.

This book consists of five sections. The first section details methods for analyzing both presynaptic and postsynaptic function and emphasizes the molecular aspects of synapses. It describes ongoing studies of neurotransmitter release, voltage- sensitive ion channels, and electronic transmission at gap junctions. The second section focuses on the growing menagerie of neurotransmitters: their catagorization into chemical families, their relation to ion channels, their modulation by second messenger systems and their role in pharmacologic action. The third section considers the important relationship of transmitter diversity and synaptic types to the behavior of actual cellular networks. All of the studies described in these sections point to the necessity of considering interactions between anatomy, chemistry, physiology and pharmacology if synaptic function is to be understood at any one of these levels of analysis.
