Prions are infectious proteins responsible for diseases such as Creutzfeldt-Jakob disease and "mad cow" disease. They are misfolded versions of normal proteins that replicate by converting their normal cellular counterparts into abnormal prion proteins that disrupt cell function and can be transmitted to other cells and individuals. This book examines our under-standing of their structure, biochemistry, and pathophysiology.
Prion-related diseases, known as transmissible spongiform encephalopathies (TSEs), are infectious, fatal neurodegenerative disorders for which there is no cure, treatment, nor even a means for early diagnosis. The horrific advent of Mad Cow Disease -- transmitted to humans through eating meat from steers sickened by bovine spongiform encephalopathy
The author, a 1997 recipient of the Noble Prize in medicine, describes the years he spent researching and demonstrating how the infectious proteins known as prions were responsible for brain diseases and how his theory has now become widely accepted in the science establishment.
This volume is a new edition of the most authoritative book on Prion Biology, first published in 1999 and edited by the Nobel Prize-winning founder of the field. This expanded edition has been completely updated, and includes chapters on therapeutics, and diagnostic methods and approaches.
Human Prion Diseases, Volume 153 is designed to update the reader on the latest advances and clinical aspects of prion diseases. The book is organized into five sections, including the pathophysiology of prions and a description of animal and human diseases. This is followed by detailed reports on recent advances in diagnosis strategies for the development of novel anti-prion molecules and possible designs of clinical trials in such a rare disease. An introductory chapter gives an extensive historical background of prion research, with a final chapter highlighting recent progress, and more importantly, unsolved problems. - Offers an authoritative overview of prion diseases in humans, detailing the pathogenesis of the disease, clinical investigations, and the diagnosis of both the genetic and acquired forms - Provides clarity and context by presenting prion diseases in relation to other neurodegenerative diseases in humans - Emphasizes the unique properties of prion diseases and consequent problems they can cause, both clinically and in public health terms
In Advancing Prion Science, the Institute of Medicine's Committee on Transmissible Spongiform Encephalopathies Assessment of Relevant Science recommends priorities for research and investment to the Department of Defense's National Prion Research Program (NPRP). Transmissible spongiform encephalopathies (TSEs), also called prion diseases, are invariably fatal neurodegenerative infectious diseases that include bovine spongiform encephalopathy (commonly called mad cow disease), chronic wasting disease, scrapie, and Creutzfeldt-Jakob disease. To develop antemortem diagnostics or therapies for TSEs, the committee concludes that NPRP should invest in basic research specifically to elucidate the structural features of prions, the molecular mechanisms of prion replication, the mechanisms of TSE pathogenesis, and the physiological function of prions' normal cellular isoform. Advancing Prion Science provides the first comprehensive reference on present knowledge about all aspects of TSEs' from basic science to the U.S. research infrastructure, from diagnostics to surveillance, and from prevention to treatment. This report summarizes the progress thus far.
A series of remarkable discoveries in the past three decades have led to the molecular and genetic characterization of the transmissible pathogen causing scrapie in animals and a quartet of human illnesses: kuru, Jakob-Creutzfeld disease, Gerstmann-Sträussler-Scheinker disease, and fatal familial insomnia. To distinguish this pathogen from viruses and viroids, the term "prion" was introduced to emphasize its proteinaceous and infectious nature. Stanley B. Prusiner, editor of this volume, was awarded the 1997 Nobel Prize in Physiology and Medicine for his pioneering discovery of prions. The book reviews advances in studies of prions, which - as considereable evidence indicates - are novel pathogens composed only of protein.
The number of neurological conditions associated with the mutant "prion" protein continues to grow. The list includes BSE and scrapie, which affect cattle and sheep respectively, and Creutzfeldt-Jacob Disease, which affects humans. This is an area of intense interest to neuroscientists,veterinary scientists, and clinicians. It has also attracted significant media attention because of the potential risks to humans. This book brings together leading researchers in the field to provide the most up-to-date and authoritative summary available of the field. Contents include human and animal prion diseases; pathology and cell biology of prion diseases; and prion protein structure.
Neurogenetics, Part II, Volume 148, the latest release in the Handbook of Clinical Neurology, provides the latest information on the genetic methodologies that are having a significant impact on the study of neurological and psychiatric disorders. Using genetic science, researchers have identified over 200 genes that cause or contribute to neurological disorders. Still an evolving field of study, defining the relationship between genes and neurological and psychiatric disorders is expected to dramatically grow in scope. Part II builds on the foundation of Part I, expanding the coverage to dementias, paroxysmal disorders, neuromuscular disorders, white matter and demyelination diseases, cerebrovascular diseases, adult psychiatric disorders and cancer and phacomatoses. - Contains comprehensive coverage of neurogenetics - Details the latest science and its impact on our understanding of neurological, psychiatric disorders - Presents a focused reference for clinical practitioners and the neuroscience/neurogenetics research community
A conformational transition of the cellular prion protein (PrPC) into an aberrantly folded isoform designated scrapie prion protein (PrPSc) is the hallmark of a variety of neurodegenerative disorders collectively called prion diseases. They include Creutzfeldt-Jakob disease and Gerstmann-Stäussler-Scheinker syndrome in humans, scrapie in sheep, bovine spongiform encephalopathy (BSE) in cattle and chronic wasting disease (CWD) in free-ranging deer. In contrast to the deadly properties of misfolded PrP, PrPC seems to possess a neuroprotective activity. More-over, animal models indicated that the stress-protective activity of PrPC and the neurotoxic effects of PrPSc are somehow interconnected. In this timely book, leading scientists in the field have come together to highlight the apparently incongruous activities of different PrP conformers. The articles outline current research on celluar pathways implicated in the formation and signaling of neurotoxic and physiological PrP isoforms and delineate future research direction. Topics covered include the physiologcial activity of PrPC and its possible role as a neurotrophic factor, the finding that aberrant PrP conformers can cause neurodegeneration in the absence of infectious prion propagation, the requirement of the GPI anchor of PrPC for the neurotoxic effects of scrapie prions, the pathways implicated in the formation and neurotoxic properties of cytosolically localized PrP, the impact of metal ions on the processing of PrP, and the role of autophagy in the propagation and clearance of PrPSc. The book is fully illustrated and chapters include comprehensive reference sections. Essential reading for scientists involved in prion research.
