Molecular Mechanisms of Dementia (Contemporary Neuroscience)

by Wilma Wasco Rudolph Tanzi

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.

Molecular Mechanisms of Hormone Action: 40. Colloquium, 6.-8. April 1989 (Colloquium der Gesellschaft für Biologische Chemie in Mosbach Baden #40)

by Ulrich Gehring Ernst J. M. Helmreich Günter Schultz

Recent years have seen tremendous progress in the field of hormone action and consequent signal transduction. The 40th Colloquium Mosbach was devoted to the discussion of results concerning the molecular process of hormone action, especially the processes following hormone binding to the corresponding receptors. Structural and functional aspects of steroid hormone receptors as well as ion-channel-coupled and enzyme-linked receptors were treated in detail. Particular interest focussed on the latest results concerning transcriptional control, protein phosphorylation, the role of G-Proteins, oncogene proteins, involvement of phospholipases and the regulation of ion channels.

Molecular Mechanisms of Inflammation: Induction, Resolution and Escape by Helicobacter pylori (Current Topics in Microbiology and Immunology #421)

by Steffen Backert

This book focuses on immune reactions and interactions of humans with Helicobacter pylori - a human pathogen connected to gastritis, peptic ulcers and even gastric cancer. With nearly half of the world’s population colonized, it has been characterized as one of the most successful pathogens for more than 100,000 years of co-evolution with its host. The respective chapters discuss not only how H. pylori infection is considered a paradigm for persistent bacterial infection and chronic inflammation, but also how the infection might be connected to host protection against gastro-esophageal diseases, asthma, and other allergic disease manifestations. Readers will gain essential insights into the roles of specific factors in the immune response and learn about the impact of genetic polymorphisms on the risk of gastric carcinogenesis. In addition, the book discusses the strategies used by this bacterium, which allow it to colonize specific sites in the stomach, interact with the microbiome, evade immune surveillance and undermine the resolution of inflammation during persistent infection. This volume presents a concise summary of recent advances in the areas of induction, resolution and escape of inflammation, innate and adaptive immunity, gastric disease development, as well as treatment and vaccination against H. pylori. Accordingly, it offers a valuable asset for scientists and clinicians alike.

Molecular Mechanisms of Membrane Traffic (Nato ASI Subseries H: #74)

by D. James Morre Kathryn E. Howell John J. M. Bergeron

The study of membrane traffic in reconstituted cell-free systems has generated an unprecedented amount of new information on the biochemistry, molecular biology and genetics of membrane-based molecular events that underly normal and abnormal cellular function. Many of the individual steps have now been isolated and dissected in simple systems that permit detailed molecular analyses of transport mechanisms and their regulation. Reconstituted events of intercompartment transport include inter-membrane recognition, and controlled membrane fusion-fission reactions. Among the many advances is the growi ng awareness of a remarkabl e evolutionary conservation of many of the components involved in the many steps of membrane traffic, this realization has accelerated greatly the pace of progress in the field. This book provides a collection of participant contributions from the 1992 Summer Research Conference, "Mol ecul ar Mechani sms of Membrane Traffi c, " jointly sponsored with NATO by the American Society of Cell Biology. The conference was held May 9-13, at the Airlie Conference Center in the Virginia countryside, near Warrenton. The conference was attended by 158 scientists. A unique feature was the high proportion of young scientists among the participants. Approximately 65% were students, postdoctoral fe 11 ows and young investigators. Each attendee contri buted to the conference with either a pl atform or poster presentation.

Molecular Mechanisms of Microbial Adhesion: Proceedings of the Second Gulf Shores Symposium, held at Gulf Shores State Park Resort, May 6–8 1988, sponsored by the Department of Biochemistry, Schools of Medicine and Dentistry, University of Alabama at Birmingham, Birmingham, Alabama

by Lech Switalski Magnus Höök Edwin Beachey

It has been 80 years since the subject of bacterial adhesion to surfaces was first brought forth, but only in the last two decades has the importance of this subject been recognized by medical microbiologists. The fact that bacterial attachment to the host tissue is a prerequisite for infection understandably led to the hope that infections could be prevented by blocking the adhesion of pathogenic bacteria. Progress in this field has been so rapid that it has become difficult to keep up with recent developments. This book contains the proceedings of the symposium on the Molecular Mechanisms of Microbial Adhesion, May 6-8, 1988. Both the symposium and this book were intended as an up-to-date review of the most recent findings concerning the adhesion of medically important bacteria. In addition, this book contains critical and provocative overviews of the past, present and future of this field.

Molecular Mechanisms of Neurotransmitter Release (Contemporary Neuroscience)

by Zhao-Wen Wang

Neurons in the nervous system organize into complex networks and their functions are precisely controlled. The most important means for neurons to communicate with each other is transmission through chemical synapses, where the release of neurotransmitters by the presynaptic nerve terminal of one neuron influences the function of a second neuron. Since the discovery of chemical neurotransmission by Otto Loewi in the 1920s, great progress has been made in our understanding of mol- ular mechanisms of neurotransmitter release. The last decade has seen an explosion of knowledge in this field. The aim of Molecular Mechanisms of Neurotransmitter Release is to provide up-to-date, in-depth coverage of essentially all major mole- lar mechanisms of neurotransmitter release. The contributors have made great efforts to write concisely but with sufficient background information, and to use figures/diagrams to present clearly key concepts or experiments. It is hoped that this book may serve as a learning tool for neuroscience students, a solid reference for neuroscientists, and a source of knowledge for people who have a general interest in neuroscience. I was fortunate to be able to gather contributions from a group of outstanding scientists. I thank them for their efforts. In particular, I want to thank Dr. Erik Jorgensen who offered valuable suggestions about the book in addition to contrib- ing an excellent chapter. I thank US National Science Foundation and National Institute of Health for their supports.

Molecular Mechanisms of Neurotransmitter Release (Advances in Neurobiology #33)

by Zhao-Wen Wang

Neurons communicate with each other by releasing neurotransmitters. This book provides comprehensive coverage of the molecular mechanisms involved in neurotransmitter release. The topics covered in the book range from the architecture and cytomatrix proteins of presynaptic sites, to the modes of synaptic vesicle exocytosis (full-collapse and kiss-and-run), and from the key molecules mediating synaptic vesicle fusion (SNAREs) to those that closely interact with them (UNC-13/Munc13, UNC-18/Munc18, tomosyn, and complexins). The book also delves into the calcium sensors of synaptic vesicle fusion (synaptotagmins and Doc2s), the sources of calcium that trigger synaptic exocytosis (voltage-gated calcium channels and ryanodine receptors), and the regulation of neurotransmitter release by potassium channels, cell adhesion molecules, lipids, aryl hydrocarbon receptor-interacting protein (AIP), presenilins, and calstabins. To aid in understanding and illustrate key concepts, the book includes sufficient background information and a wealth of illustrations and diagrams. The new edition includes major updates to previous chapters, as well as several new chapters that reflect the recent advances in the field. Comprehensive and cutting-edge, Molecular Mechanisms of Neurotransmitter Release, 2nd edition, is a valuable learning resource for neuroscience students and a solid reference for neuroscientists.

Molecular Mechanisms of Parasite Invasion (Subcellular Biochemistry #47)

by Barbara A. Burleigh Dominique Soldati

All of the parasitic organisms highlighted in this new book represent medically important human pathogens that contribute significantly to the global burden of disease. As such there is intense interest in understanding the molecular basis of infection by these pathogens—not only with regard to their clinical relevance but also the fascinating biology they reveal. For most of the parasites discussed here the ability to penetrate biological barriers and/or to establish intracellular residence is critical to survival of the pathogen in the mammalian hosts. For other parasites, a tissue invasive phenotype is a key virulence determinant. In the ensuing 18 chapters, select members of this diverse set of protozoan parasites, as well as some examples of the extremely reduced fungal parasites classified as Microsporidia, are discussed within the context of the fascinating molecular strategies employed by these organisms to migrate across biological barriers and to establish residence within target host cells.

Molecular Mechanisms of Phagocytosis (Medical Intelligence Unit)

by Carlos Rosales

Although, Phagocytosis was first described nearly 120 year ago, we are just recently beginning to understand the molecules that phagocytic cells use to bring about this complex cell function. Molecular Mechanisms of Phagocytosis was prepared as a series of up-to-date essays (chapters) that describe the present knowledge on the various steps of the phagocytic process from initial cell contact, through internalization of the foreign particle, to the final phagosome formation where the phagocytosed particle is destroyed.

Molecular Mechanisms of Programmed Cell Death

by Yun-BoShi Jia-RuiWu DavidScott John A. Cidlowski YufangShi

The 2002 Nobel Prize in Physiology or Medicine was awarded to Sydney Brenner, H. Robert Horvitz, and John E. Sulston for their seminal discoveries concerning "genetic regulation of organ development and programmed cell death." This clearly marked the prime importance of understanding the molecular mechanisms controlling cell death. The 1 st International Symposium on Programmed Cell Death was held in the Shanghai Science Center of the Chinese Academy of Sciences on September 8-12, 1996. A number of key issues in apoptosis were discussed at the meeting, and progress in major areas of apopto­ sis research was summarized by expert participants at the meeting and published by Plenum Publishing Corporation as a book entitled Programmed Cell Death. In the last six years, we have witnessed a real explosion in our knowledge on how cells undergo apoptosis, thereby participating in various developmental and pathophysiological processes. At this ever­ exciting time, we organized the 2nd International Symposium on Programmed Cell Death.

Molecular Mechanisms of Retina Pathology and Ways of its Correction

by Svetlana Trofimova

This book discusses the pathology of the retina, and reviews current research on the use of cell replacement therapy and short peptides to restore functional activity in retinal neurons. As the book describes, pathologies of the retina, including age-related macular degeneration, diabetic retinopathy, and retinitis pigmentosa, present a long-standing challenge in the practice of clinical ophthalmology. Modern treatment for these conditions, which lead to irreversible blindness, includes laser exposure, surgical intervention, and drugs. These treatments aim to reduce the risk of new complications in the eye; pathogenetic therapy of degenerative diseases of the retina is practically absent in current ophthalmic practice. The first section of the book reviews the molecular mechanisms of age-related macular degeneration, diabetic retinopathy, and retinitis pigmentosa, and reports on methods of treatment. The second section presents the results of recent experimental studies of the effects of short peptides on pluripotent embryonic cells; on proliferative activity in retinal cells and pigment epithelium; on expression of markers of differentiation or retinal neurons and pigment epithelium; and on the course of hereditary retinal pigmentation in Campbell rats. The third section offers results of clinical studies on the effectiveness of short peptides in patients with macular degeneration, and in patients with retinitis pigmentosa. The author concludes that the regular use of peptides in the treatment of degenerative diseases of the retina can slow the progression of the pathological process and preserve the patient’s vision for some 10-15 years. In addition, in 80 percent of patients, it is possible to increase visual function by increasing visual acuity, improving the boundaries of the visual field and the fundus.

Molecular Mechanisms of Spondyloarthropathies

by Carlos López-Larrea Roberto Díaz-Peña

It is now over ten years since we edited the first edition of HLA-B27 in the Development of Spondyloarthropathies (SpA). It is obvious that over this period an enormous amount of information concerning SpA and HLA-B27 has accumulated, and this has been reflected in the knowledge of molecular mechanism of the spondyloarthropathies. Discussion for such a book took initial form at the outstanding 4th Gent Symposium on SpA in October 2006, but was not formally commissioned by Landes Bioscience until early 2007. Molecular Mechanisms of Spondyloarthropathies aims to synthesize this growing knowledge and present all the current studies concerning the basic research of SpA. Over the last decade, enormous progress has been made in the understanding of the molecular and cellular processes that lead to disease pathology. Recognition of the pathways involved in the pathogenic mechanisms of disease and the potential to target specific immune effector functions have opened the door to a wide range of innovative treatment opportunities for the SpA. Thus, we believe that the understanding of the specific molecular mechanisms involved would help to design highly specific drugs in the future. The contributors are among the best in their field and reflect the state of the art of research and current opinion of rheumatologists and immunologists.

Molecular Mechanisms of Tumor Cell Resistance to Chemotherapy: Targeted Therapies to Reverse Resistance (Resistance to Targeted Anti-Cancer Therapeutics #1)

by Benjamin Bonavida

​​​​​This volume gives the latest developments in on the mechanisms of cancer cell resistance to apoptotic stimuli, which eventually result in cancer progression and metastasis. One of the main challenges in cancer research is to develop new therapies to combat resistant tumors. The development of new effective therapies will be dependent on delineating the biochemical, molecular, and genetic mechanisms that regulate tumor cell resistance to cytotoxic drug-induced apoptosis. These mechanisms should reveal gene products that directly regulate resistance in order to develop new drugs that target these resistance factors and such new drugs may either be selective or common to various cancers. If successful, new drugs may not be toxic and may be used effectively in combination with subtoxic conventional drugs to achieve synergy and to reverse tumor cell resistance. The research developments presented in this book can be translated to produce better clinical responses to resistant tumors.

Molecular Mechanisms Underpinning the Development of Obesity

by Clévio Nóbrega Raquel Rodriguez-López

Obesity is a multi-factorial disease, in which an excess of accumulated body fat can reach levels capable of affecting health. It results from an interplay between environmental factors, eating behavior, genes, epigenetics, and neuronal stimuli. The main aim of this book is to provide a state-of-the-art revision about the molecular mechanisms underpinning the development of obesity, reviewing the current knowledge in areas like monogenic and polygenic obesity forms, but also providing an updated view of the emerging knowledge about epigenetics, nutrigenomics, and neuronal aspects that also contribute to obesity.

Molecular Medicine: How Science Works

by Carsten Carlberg Eunike Velleuer Ferdinand Molnár

The fascinating area of molecular medicine provides a molecular and cellular description of health and disease. Starting with the understanding of gene regulation and epigenetics, i.e., the interplay of transcription factors and chromatin, this book will provide an fundamental basis of nearly all processes in physiology, both in health as well as in most common disorders, such as cancer, diabetes as well as in autoimmune diseases. Most non-communicable human diseases have a genetic (= inherited) as well as an epigenetic component. The later one is based on our lifestyle choices and environmental exposures. Many common diseases, such as type 2 diabetes, can be explained only to some 20% via a genetic predisposition. We cannot change the genes that we are born with but we can take care of the remaining 80% being primarily based on our epigenome. Therefore, there is a high level of individual responsibility for staying healthy. Thus, not only biologists and biochemists should be aware of this topic, but all students of biomedical disciplines will benefit from being introduced into the concepts of molecular medicine. This will provide them with a good basis for their specialized disciplines of modern life science research. The book is subdivided into 42 chapters that are linked to a series of lecture courses in “Molecular Medicine and Genetics”, “Molecular Immunology”, “Cancer Biology” and “Nutrigenomics” that is given by one of us (C. Carlberg) in different forms since 2002 at the University of Eastern Finland in Kuopio. This book represents an updated version and fusion of the books textbooks “Mechanisms of Gene Regulation: How Science Works” (ISBN 978-3-030-52321-3), “Human Epigenetics: How Science Works” (ISBN 978-3-030-22907-8). “Molecular Immunology: How Science Works” (ISBN 978-3-031-04024-5), “Cancer Biology: How Science Works” (ISBN 978-3-030-75699-4) and “Nutrigenomics: How Science Works” (ISBN 978-3-030-36948-4). By combining basic understanding of cellular mechanism with clinical examples, the authors hope to make this textbook a personal experience. A glossary in the appendix will explain the major specialist’s terms.
