As the research has continued, it has become increasingly clear that natural killer (NK) cells are critical sentinels of the innate immune response, playing important roles in protecting the body from numerous pathogens and cancer in addition to contributing to normal pregnancy and impacting the outcomes of transplantation. While the first edition provided a valuable collection of classical cellular and in vivo techniques to study NK cell functions, the Second Edition of "Natural Killer Cell Protocols: Cellular and Molecular Methods" brings together more recently developed methods, more refined techniques, and detailed protocols designed to study NK cells within specialized tissue sites in both mice and humans. In this collection of methods, international leaders in the field cover topics ranging from the analysis of the various stages of NK cell development and maturation to specialized techniques for the identification of ligands for NK cell receptors. This volume also includes an appendix, providing a rich resource summarizing available reagents to study NK cells, cross-referencing KIR nomenclature, and detailing the many HLA ligands for various KIR family members. As a volume in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and thorough notes sections, highlighting tips on troubleshooting and avoiding known pitfalls. Comprehensive and cutting-edge, "Natural Killer Cell Protocols: Cellular and Molecular Methods, Second Edition" seeks to aid researchers and further advance our understanding of the functions, maturation, and regulation of these fascinating and dynamic cells."

Each chapter explains the physics of the mechanism at work, and reviews common geometries and devices to help readers decide the type of style of device required for various applications. This book is appropriate for graduate-level biomedical engineering and analytical chemistry students, as well as engineers and scientists working in the biotechnology industry.
Microbial cell wall structures play a significant role in maintaining cells' shape, as protecting layers against harmful agents, in cell adhesion and in positive and negative biological activities with host cells. All prokaryotes, whether they are bacteria or archaea, rely on their surface polymers for these multiple functions. Their surfaces serve as the indispensable primary interfaces between the cell and its surroundings, often mediating or catalyzing important interactions. "Prokaryotic Cell Wall Compounds" summarizes the current state of knowledge on the prokaryotic cell wall. Topics concerning bacterial and archaeal polymeric cell wall structures, biological activities, growth and inhibition, cell wall interactions and the applications of cell wall components, especially in the field of nanobiotechnology, are presented.
Strategies of Bacterial Interaction with Eukaryotic Cells *Tobias A. Oelschlaeger and Jorg Hacker 1. BENEFICIAL BACTERIAL-HOST INTERACTIONS Already during birth and soon thereafter mammals are colonized by bacte- ria belonging to the resident microbial flora. Cutaneous and mucosal sur- faces and the gastrointestinal tract are the areas which become colonized. These indigenous or autochthonous bacteria have a variety of beneficial effects on their hosts. They play a protective role by bacterial antagonism in fighting infections (Hoszowski and Truszczynski, 1997; Hentges, 1979). Pro- duction of vitamin K is another essential contribution of the resident microbial flora to the health of the host (Hill, 1997). Even more important, studies with germ-free animals demonstrated the involvement of the microbial flora on the development of the immune system. Such animals have underdeveloped and relatively undifferentiated lymphoid tissues and low concentrations of serum immune globulins ( Cebra et at., 1998). They TOBIAS A.

Oelschlaeger and Jorg Hacker also show defects in specific immune responsiveness and in nonspecific resistance induced by endotoxin, which may account for their lowered resis- tance. A more typical example of symbiotic interaction of bacteria with a host are bacteria like Ruminococcus in the gut of ruminants, essential for degradation of cellulose (Hobson, 1988). The closest benefical bacterial-host interactions are those of intracellular symbiotic bacteria and their host cells.
Stem Cells and CNS Development critically reviews recent findings
on stem cells, their involvement in neurogenesis and gliogenesis,
and the therapeutic implications of these findings. It defines by
consensus the classes of stem cells in the nervous system, compares
their similarities and differences, discusses the gains made in
identifying human homologs of neural stem cells, and describes how
these cells are beginning to be used
The present volume is the first in the advances in oncobiology series. It is meant to be useful not only to clinical and non-clinical oncologists but also to graduate students and medical students. The individual chapters are presented as self-contained summaries of current knowledge rather than as reviews. The last chapter deals with the subject of chemotherapy.
The root is the organ that functions as the interface between the plant and the earth environment. Many human management practices involving crops, forests and natural vegetation also affect plant growth through the soil and roots. Understanding the morphology and function of roots from the cellular level to the level of the whole root system is required for both plant production and environmental protection. This book is at the forefront of plant root science (rhizology), catering to professional plant scientists and graduate students. It covers root development, stress physiology, ecology, and associations with microorganisms. The chapters are selected papers originally presented at the 6th Symposium of the International Society of Root Research, where plant biologists, ecologists, soil microbiologists, crop scientists, forestry scientists, and environmental scientists, among others, gathered to discuss current research results and to establish rhizology as a newly integrated research area.
The last few years have witnessed an explosion of both interest and knowledge about apoptosis, the process by which a cell actively commits suicide. The number of publications on the topic has increased from nothing in the early 1980s to more than 10,000 papers annually today. It is now well recognized that apoptosis is essential in many aspects of normal development and is required for maintaining tissue homeostasis. The idea that life requires death seems somewhat paradoxical, but cell suicide is essential for an animal to survive. For example, without selective destruction of "non-self" T cells, an animal would lack immunity. Similarly, meaningful neural connections in the brain are whittled from a mass of cells. Further, developmental cell remodeling during tissue maturation involves programmed cell death as the major mechanism for functional and structural safe transition of undifferentiated cells to more specialized counterparts. Apoptosis research, with roots in biochemistry, developmental and cell biology, genetics, and immunology, embraces this long-ignored natural law. Failure to properly regulate apoptosis can have catastrophic consequences. Cancer and many diseases (AIDS, Alzheimer's disease, Parkinson's disease, heart attack, stroke, etc. ) are thought to arise from deregulation of apoptosis. As apoptosis emerges as a key biological regulatory mechanism, it has become harder and harder to keep up with new developments in this field.

Most organisms and populations have to cope with hostile environments, threatening their existence. Their ability to respond phenotypically and genetically to these challenges and to evolve adaptive mechanisms is, therefore, crucial. The contributions to this book aim at understanding, from a evolutionary perspective, the impact of stress on biological systems. Scientists, applying different approaches spanning from the molecular and the protein level to individuals, populations and ecosystems, explore how organisms adapt to extreme environments, how stress changes genetic structure and affects life histories, how organisms cope with thermal stress through acclimation, and how environmental and genetic stress induce fluctuating asymmetry, shape selection pressure and cause extinction of populations. Finally, it discusses the role of stress in evolutionary change, from stress induced mutations and selection to speciation and evolution at the geological time scale. The book contains reviews and novel scientific results on the subject. It will be of interest to both researchers and graduate students and may serve as a text for graduate courses.
The aim of the former editions remains unchanged in the present updated version, namely to put forward a general and comprehensive review on complement. It is intended not only for individual investigators working in this specific field, but also for those who are less familiar with it. Students or younger scientists will hopefully be stimulated and attracted by the fascination of complement biology. Again, it was clear from the beginning that the field has experienced an explosive expansion in various directions and continues to accumulate data too large to be dealt with by a single author in a critical and coherent manner. The editors are grateful that the invited authors, all of them leading scientists in their field, helped again to make The Complement System a true mirror of the state of the art. Some parallels in the various chapters were accepted, as was a particular emphasis on newer developments in some chapters.

This book is a direct result of 10 years of the well-known
"Autoimmunity Days" in Israel, which are increasingly becoming an
international focal point for autoimmunity scientists. Top
researchers provide coverage of the most important knowledge
generated during the last decade. The volume can therefore be seen
almost as a textbook on autoimmunity, projecting from the last
decade to the next millennium.
The revolution in biological research initiated by the
demonstration that particular DNA molecules could be isolated,
recombined in novel ways, and conveniently replicated to high copy
number in vivo for further study, that is, the recombinant DNA era,
has spawned many additional advances, both methodological and
intellectual, that have enhanced our understanding of cellular
processes to an astonishing degree. As part of the subsequent
outpouring of information, research exploring the mechanisms of
gene regulation, both in prokaryotes and eukaryotes (but
particularly the latter), has been particularly well represented.
Although no one technical approach can be said to have brought the
filed to its current level of sophistication, the ability to map
the interactions of trans-acting factors with their DNA recognition
sequences to a high level of precision has certainly been one of
the more important advances. This "footprinting" approach has
become almost ubiquitous in gene regulatory studies; however, it is
in its ""in vivo"" application that ambiguities, confusions, and
inconsistencies that may arise from a purely ""in vitro""-based
approach can often be resolved and placed in their proper
perspective. Put more simply, that an interaction can be
demonstrated to occur between purified factors and a particular
piece of DNA in a test tube does not, of course, say anything
regarding whether such interactions are occurring "in vivo." The
ability to probe for such interactions as they occur inside cells,
with due attention paid to the relevant developmental stage, or to
the tissue specificity of the interaction being probed, has made
"in vivo" footprinting approach an invaluable adjunct to the "gene
jockey's" arsenal of weapons.
Fas Signaling is focused on the signaling mechanisms and biology of the prototypic death receptor Fas, also called CD95 or APO-1. The chapters of this book cover, besides the well recognized apoptosis-related functions of Fas, its emerging role as a proinflammatory cytokine and as an inducer of alternative forms of cell death. Fas Signaling aims to provide the reader with an up-to-date survey of the various aspects of Fas biology and the open questions of the field are addressed. This title is intended for Ph.D and post-doctoral students starting to work in the field, but is also useful for everyone with an interest in the biology of this exciting molecule.

The development of liposomes as a drug delivery system has fluctuated since its introduction in the late 1960's by A.D. Bangham. While academic research of liposomes as a model membrane system has always flourished, as the exponential growth of papers can testify, the application of these findings to medically useful products has gone through several crises. Following the original optimism in the 70's and early 80's, a period of severe skepticism ensued at the end of the 80's and beginning of the 90's, culminating in a moderate but real optimism in the mid 90's, as a result of a successful launch of the first products in the US and Europe. In this collection of papers, the editors have gathered the most promising ideas, approaches, applications and commercial developments, thereby presenting an up-to-date compilation of the present status of the field. This includes such broad areas as anti-cancer chemotherapy immune stimulation and infectious diseases. Currently, the major areas of progress are in delivery of anti-fungal agents by conventional liposomes or lipid-based carriers and systemic anticancer therapy using long-circulating liposomes. The future applications as characterized by the direction of present day research is in specific targeting and delivery of informational molecules such as DNA plasmids (genes), antisense oligonucleotides or ribozymes. Other future developments may be in topical delivery, vaccination and in diagnostics. Features of this book: Contributions from almost all the leading labs in the field Up-to-date, critical reviews bridged by editors' introductions Organized into a logical framework."

The Endoplasmic Reticulum (ER) is an organelle with extraordinary signaling and homeostatic functions. It is the organelle responsible for protein folding, maturation, quality control and trafficking of proteins destined for the plasma membrane or for secretion into the extracellular environment. Failure, overloading or malfunctioning of any of the signaling or quality control mechanisms occurring in the ER may provoke a stress condition known as ER stress . Accumulating evidence indicates that ER stress may dramatically perturb interactions between the cell and its environment, and contribute to the development of human diseases, ranging from metabolic diseases and cancer to neurodegenerative diseases, or impact therapeutic outcome. This book primarily focuses on the pathophysiology of ER stress. It introduces the molecular bases of ER stress, the emerging relevance of the ER-mitochondria cross-talk, the signaling pathways engaged and cellular responses to ER stress, including the adaptive Unfolded Protein Response (UPR), autophagy as well as cell death. Next the book addresses the role of ER stress in physiology and in the etiology of relevant pathological conditions, like carcinogenesis and inflammation, neurodegeneration and metabolic disease. The last chapter describes how ER stress pathways can be targeted for therapeutic benefit. Altogether, this book will provide the reader with an exhaustive view of ER stress biology and the latest insights in the role of ER stress in relevant human diseases."
How do you keep track of basic information on the proteins you work
with? Where do you find details of their physicochemical
properties, amino acid sequences, and structure? Are you tired of
scanning review articles, primary papers, and databases to locate
that elusive fact?
Gaining an understanding of the mechanisms by which cells process and respond to extracellular cues has become a major goal in many areas of bi- ogy and has attracted the attentions of almost every traditional discipline within the biological sciences. At the heart of these divergent endeavors are common methods that can aid biochemists, physiologists, and pharmacologists in ta- ling the specific questions addressed by their research. In Receptor Signal Transduction Protocols, a diverse array of meth- ologies employed to interrogate ligand--receptor and receptor-effector int- actions are described by authors who have devised and successfully applied them. The authors blend excellent descriptions and applications of fairly well established methodologies with new technologies at the cutting-edge of signal transduction research and as such I hope the present volume will complement and extend a previous excellent volume in this series edited by David Kendall and Stephen Hill (Methods Molecular Biology, vol. 41, Signal Transd- tion Protocols). |
