This volume provides in-depth reviews of model systems that exemplify the arms race in host-pathogen interactions. Somatic adaptations are responsible for the individualization of biological responses to the environment, and the continual struggle between host immune systems and invading pathogens has given rise to corresponding processes that produce molecular variation. Whether in mollusks or human beings, various host somatic mechanisms have evolved independently, providing responses to counter rapidly-changing pathogens. The pathways they utilize can include non-heritable changes involving RNA and post-translational modifications, or changes that produce somatic DNA recombination and mutation. For infectious organisms such as protozoans and flatworms, antigenic variation is central to their survival strategy. Evolving the ability to evade the host immune system not only increases their chances of survival but is also necessary for successful re-infection within the host population.

Basophils and mast cells are similar but unique secretory cells with a well-documented role in immediate-hypersensitivity reactions. The presence of these cells in various cell mediated hypersensitivity reactions, in tissues of multiple diseases, and as a component of the host reaction to injury and repair in numerous circumstances is well known. Release of stored and newly generated mediators of inflammation from basophils and mast cells contributes to the cascade of pathogenetic events in circumstances under which these release reactions occur. Despite insights acquired through studies of these pathologic events, the role of basophils and mast cells and their secretory products in health is not known. In this book, I review much of the structural information regarding basophils and mast cells of multiple species. Ultrastructural studies of rat mast cells historically precede and quantitatively exceed similar studies of basophils and mast cells of other species. Therefore, I first review these background studies as an entity. Then I discuss the contents of two prominent organelles-granules and lipid bodies-in basophils and mast cells of several species. The ultrastructural morphology of basophils and mast cells in three species is presented in detail to establish appropriate guidelines for their recognition and to provide general rules for analysis which are appropriate for the identification of these cells in other species as well."

This Methods in Molecular Biology book offers methods for studying inflammasome function, including generation of inflammasome stimuli, monitoring of caspase-1 activity and processing, activation of IL-1 cytokines, plus lab protocols, material lists and tips.

ISPP2009, the 13th International Symposium on Phototrophic Prokaryotes, was held in Montreal, Canada, from August 9 to August 14. This was only the second time that the ISPP series was in North America. ISPP2009 was well attended with about 280 registered participants from over 30 countries. A stimulating and inf- mative program showcased the recent developments in this ever-evolving eld. This is always one of my favourite conference series to attend because not only does it inform my speci c research passions, it broadly educates me in ways that improve my teaching and increase my breadth of understanding in a variety of outside areas. Indeed, the ISPP series brings together a broad spectrum of interests, techniques, and disciplines. Both established researchers and newcomers to this eld gave oral presentations in a large number (80) of plenary and parallel symposia sessions which proved to have active audience participation and lively discussions. A large number of excellent poster presentations supplemented the oral program. I think that the high quality of the scienti c presentations, as well as the enjoyable social events, was widely appreciated. Things ran very smoothly, from the original registration to the closing ceremony, thanks to Isabel Stengler and her team at IS Event Solutions.

A broad range of leading academics from Europe and North America reflect on the ways in which Dunning's work has influenced their own research and understanding of sport.

This volume was previously published as a special issue of the journal Sport in Society.

Interleukins are a family of proteins that regulate the maturation, diff- entiation, or activation of cells involved in immunity and inflammation, and belong to a broader family termed cytokines. Collectively these proteins are the key orchestrators of host defense and the response to tissue injury. There are currently 23 different interleukins (numbered from IL-1 to IL-23), although the full extent of the interleukin family will only become clear upon analysis of the human genome sequence. Most important, interleukins are central to the pathogenesis of a wide range of diseases that involve an immune com- nent, including such conditions as rheumatoid arthritis, multiple sclerosis, ulcerative colitis, psoriasis, and asthma. Interleukins have also been imp- cated in other conditions, including cancer, migraine, myocardial infarction, and depression. In essence, when cells are activated by interleukins, a program of gene expression is initiated in the target cell that alters the cell's phenotype, leading to enhanced immune reactivity, inflammation, and/or proliferation. Interleukins are therefore at the core of the cellular basis for many diseases. They are the subject of intense investigation by biomedical researchers and the targeting or use of interleukins in the clinic is proceeding apace. Approaches such as t- geting IL-4 in asthma or IL-1 in joint disease are being pursued, and it is likely that in the next 5-10 years a number of new therapies based on either inhib- ing or administering interleukins will be available.

A synthesis of current concepts about the evaluation, treatment, and future directions in MS. On the evaluation side, the authors review the use of MRI, magnetic resonance spectroscopy, functional MRI, and three-dimensional MRI, and consider the rapidly developing body of pathologic information they have yielded. On the treatment side, the focus is on recently approved medications (Novantrone), new indications for medications (CHAMPS Trial), medications in development (Oral Interferon Tau, Oral Copaxone, and Oral Cellcept), immunosuppressive therapy for both progressive disease and symptomatic therapy; the current medications for treating relapsing-remitting MS (Avonex, Betaseron, and Copaxone) are also discussed. For future directions, the authors present the current best thinking, as well as the latest discoveries in immunology relating to MS, including groundbreaking B-cell research and its applications to specific immunotherapies, and the use of immune markers for tracking the disease.

Immune Mechanisms in Inflammatory Bowel Disease is a highly, concise update of the most recent advances in the immunobiology, genetics and microbiology related to Inflammatory Bowel Disease. This book broadly treats the topics that lead to understanding of the pathogenesis of this disease in an organized, systematic approach.

The understanding of the role of dendritic cells (DCs) in immune responses has come a long way since Steinmann and colleagues described these cells in 1972. - tensive research during the intervening period has provided a good understanding of the complexity of the DC system and its pivotal role in immunity. It is also now clearer how different subsets of DCs interact and regulate each other and how DC populations affect the function of other cells of the immune system. The improved understanding of their role in immune response has led to the idea that modulation of DC functions by, for example, pharmacological agents could be used as a pot- tial therapeutic approach in some pathological conditions. The actual applicability and therapeutic potential of all these approaches is yet to be fully demonstrated but nonetheless, animal models of human diseases are proving to be very helpful in the evaluation of manipulated DCs as a new treatment in diseases like cancer, auto- munity or asthma. DCs are integral to the initiation and regulation of immune response (Banchereau et al. 2000). The outcome of antigen presentation by DCs is determined by their maturation status, which can be induced by their interaction with danger signals. To recognise a wide array of pathogen-associated molecular patterns (PAMP), DCs express a number of pattern recognition receptors (PRR) such as Toll-like rec- tors (TLRs) and C-type lectin receptors (CLR) that recognise structural components of pathogens and discriminate between self and non-self molecules.

W. B. Harrison, B. A. C. Dijkmans During the last decade intervention has been instituted for all kinds of disease- even in a premorbid state, as early as possible, to control the activity of the disease, to avoid further damage and to maintain quality of life. Apart from the principle 'Treat now, not later," emphasis is laid on aggressive initial therapy. These adagia have influenced in recent times all fields of medicine, from oncology to infectious diseases and also - the topic of the present edition - the "autoimmune diseases." As an example of the latter, rheumatoid arthritis (RA) demonstrates how the attitude of physicians has been changed. From an expectant point of view in the eighties (primum nil nocere) the attitude has been changed, as we approached and entered the new millennium, to initial ag gressive therapy especially in patients with a poor prognosis. Despite the advance of instituting monotherapy with a single optimised disease-modifying anti-rheumatic drug (DMARD) - with methotrexate as prototype agent in RA - adequate disease re mission is not often achieved, and adverse events may well prevent the use of higher dosages of the single agent in question. Therefore, the next step was to combine two or more DMARDs. The choice of combining DMARDs can be purely practical and based upon the anti-rheumatics most used in daily practice, for instance methotrexate and sulphasalazine. The choice of combining drugs can be influenced by different toxicity patterns to avoid cumulative toxicity."

Whole new areas of immunological research are emerging from the analysis of experimental data, going beyond statistics and parameter estimation into what an applied mathematician would recognise as modelling of dynamical systems. Stochastic methods are increasingly important, because stochastic models are closer to the Brownian reality of the cellular and sub-cellular world.

Integrating Population Outcomes, Biological Mechanisms and Research Methods in the Study of Human Milk and Lactation is the product of the 10th Conference of the International Society for Research on Human Milk and Lactation, held on September 15-19, 2000, in Tucson, Arizona. The presented sessions at the meeting are as diverse as the volume itself. These sessions include the impact of micronutrient deficiencies during lactation on maternal and infant health, the premature infant, developmental immunology, breastfeeding in the industrialized world, and viral transmission in milk. Whenever possible, the sessions were organized to include human population research, research showing the biological underpinnings of the effects on human health, and important methodological issues. This volume is a contemporary and influential tool for human milk biologists, breastfeeding epidemiologists, biochemists, immunologists, clinical specialists, and all professionals and researchers in the field.

Our own experience shows that there is no simple, yet of good scientific and clinical quality guide for practitioners and patients on gastrointestinal diseases. In the proposed book we will cover a vast area in the field, from GI tract physiology to disease diagnosis and treatment, in a comprehensive and approachable manner. The guide will not replace online resources (often used by patients) or specialized editions addressing experienced medical doctors, but rather fill the gap between those two. Our aim is to design this book so that it appeals to a wider audience; yet - if needed - encourages to explore the field further.

This book provides an essential update on the startling array of novel insecticidal toxins and drugs produced by the fascinating bacterium Photorhabdus. The respective chapters describe everything from the detailed molecular biology of the 'Toxin complexes' or Tc's to the complexity of insect immune response in relation to both the bacterium and its nematode vector. The volume covers both primary (toxin production and regulation) and secondary (natural product synthesis and regulation) metabolism and emphasises the potential use of toxins and drugs in both agriculture and medicine. It also discusses in detail two totally novel quorum sensing mechanisms and the likely role of LuxR solos in sensing the presence of different bacterial hosts. Lastly, the book explores the unique case of P. asymbiotica, which seems to have evolved the ability to infect both insects and humans. This synthesis proves that Photorhabdus truly does offer a 'gold mine' for the discovery of novel insecticidal proteins and novel natural products with potential uses in agriculture and medicine alike.

The knowledge of Th17 cells and other cell populations which secrete IL-17A, and/or IL-22 has expanded tremendously since the publication of the first edition "Th17 Cells: Role in Inflammation and Autoimmune Disease" in 2008. The present volume has been completely revised with the addition of new chapters on the IL-17 receptor family and signaling, and an in-depth review of IL-22 and innate lymphoid cells. The differentiation of na ve T cells into regulatory T cells and Th17 cells as well as the plasticity of Th17 cells is discussed. The role of IL-22 in cutaneous inflammation including psoriasis has been reviewed. In addition, the volume contains critical updates on autoimmunity, organ transplantation, tumor immunology and genetic mouse models for mechanistic studies. Lastly, the latest clinical progress in neutralizing antibodies to IL-17A, IL-17RA not only confirms the therapeutic promise foreseen in 2008, but also improves our knowledge of the pathogenesis of autoimmune diseases. In summary, this is a timely update and important review of the clinical and experimental aspects of IL-17, IL-22 and their producing cells.

Seventeen years after its initial description, nuclear factor-KB (NF-KB) endures as one of the most studied transcription factors. NF-KB has attracted widespread interest based on the variety of stimuli that activate it, the diverse genes and bio logical responses that it controls, the striking evolutionary conservation of struc ture and function among species, and its involvement in a variety of human diseases. The biochemical basis by which several stimuli converge to activate NF-KB has been largely elucidated during recent years. While first discovered as a key regulatory factor of the immune system, NF-KB is now recognized as an important player in the functioning of many organs and cell types. The ongoing examination of NF-KB signaling has revealed its ever expanding role in immune and inflammatory responses, but also in cancer and development. For this reason, numerous efforts are underway to develop safe inhibitors of NF-KB to be used in the treatment of both chronic and acute disease situations. The present book is the first to review and synthesize our knowledge of this interesting transcription factor. As such, the choice of subjects to review was daunting. To set the stage, an introductory chapter on activators and target genes, as well as the role they play in several responses, has been included."

During the past fifty years, thousands of natural products have been isolated from plants, fungi, and bacteria. Apart from intense searches by pharmaceutical companies for medicinals and the concentrated effort mounted by the National Cancer Institute, many of these have not been tested in biological systems. The major reasons for this appear to be, at least, twofold. First, individual researchers looking for biologically active natural products will often isolate only small amounts of material sufficient to determine a structure and calculate the specific activity for their particular bioassay systems: insufficient funds preclude re-isolating the compound unless industrial potential is foreseen. Second, the difficulty with which original structures were proved prior to 1972. This required the isolation of relatively large quantities of a natural product and there followed extensive degradation, elemental analyses of the parent and its fragments, then synthesis, piece by piece, of the molecule. All this took time and energy. No wonder that when the structure was proved the chemist was enervated. And coupled to this was the fact that many chemists were not trained to test their materials in biological systems. In contrast, today a natural product can be isolated, its mass and molecular formula determined and, if there is some serendipity, crystals may be obtained for single crystal x-ray analysis. If conditions are near perfect, it is possible to isolate and identify a novel compound in a month.

 TOR, the Target of Rapamycin was discovered a little over ten years ago in a genetic screen in S. cerevisiae in search of mutants resistant to the cytostatic effects of the antimycotic, rapamycin. Recent studies have placed TOR at the interface between nutrient sensing and the regulation of major anbolic and catabolic responses. The editors have gathered the leading figures in the field of TOR and its role in cellular homeostasis and human diseases.
