The intestine is the front line of the confrontation between pathogens and the immune system. However, it is also important to emphasize that we have a symbiotic relationship with innumerable bacteria in the intestine. In the gastrointestinal tract of mammals the lower intestine harbors around 1,000 12 species of anaerobic and aerobic bacteria, in densities up to 10 /mlinthe distal small intestine, the cecum, and the colon. A single layer of epithelial cells of the intestine protects the internal organs of the mammalian host from these bacteria. Below these epithelial cells the gut-associated lymphoid tissues (GALT), organized in Peyer's patches, cryptopatches, and isolated l- phoid follicles, as well as isolated, dispersed single cells in the epithelial layer (intraepithelial lymphocytes) and lamina propria, are composed of T l- phocytes, B lymphocytes, Ig-secreting plasma cells, and antigen-presenting cells such as dendritic cells. The importance of the gut barrier is striking, if we consider that in humans the epithelial surface, behind which the immune system faces and senses the endogenous bacteria, is estimated to be as large as a basketball court. Perhaps not surprising then, the gut contains appr- imately half of all lymphocytes of our immune system. Colonization of the intestine with the ?ora of commensal bacteria induces the development of the GALT, which in turn responds by the development of IgA-secreting plasma cells. Dimeric and multimeric IgAs can traverse the epithelial layer and are released in the gut lumen, where they bind bacteria.

This volume examines in detail the role of chronic inflammatory processes in the development of several types of cancer. Leading experts describe the latest results of molecular and cellular research on infection, cancer-related inflammation and tumorigenesis. Further, the clinical significance of these findings in preventing cancer progression and approaches to treating the diseases are discussed. Individual chapters cover cancer of the lung, colon, breast, brain, head and neck, pancreas, prostate, bladder, kidney, liver, cervix and skin as well as gastric cancer, sarcoma, lymphoma, leukemia and multiple myeloma.

The justification for yearbooks is greater than ever as we approach the third millennium, overwhelmed with information. This first edition of the Cytokine Yearbook summarizes the latest advances in the revolutionary field of cytokine research. The work is not a comprehensive reference work, but covers a selection of current themes. The intention is to keep paying attention to current topics in the Yearbooks to come. The editors invited a number of distinguished colleagues, who are international experts in their specific fields, resulting in a high scientific level of the contributions. This Yearbook is required reading for every scientist and physician working in the field of cytokines.

"De la vaporisation et de la centralisation du Moi. Tout est la. " Charles Baudelaire (journal entry) This anthology is my visit to Oz. On sabbatical in 1988, I chose to reeducate myself in general biology, first broadening my erudition as an immunologist, and then extending that horizon into evolutionary biology and embryology. I was particularly attracted to reflections on the nature of the self as an organ ismic concept. I went in search of reorientation as a confused physician scientist, and came back with this book. Baum's Wizard of Oz presented opportunities for growth, and herein lies the purpose of this volume: in providing updated statements concerning the nature of the organism from both scientific and metaphysical perspectives, we might ponder the philo sophical basis of our research in the hope of gaining insight into our endeavor, not to mention the possibility of its enrichment; it is this contem plative view of our research which offers a unique dimension to this anthology. To that end, the project follows my idiosyncratic prejudices. The anthology derives in large measure from the symposium, "Organism and the Origin of Self' held at Boston University, April 3-4, 1990, under the auspices of the Boston University Center for the Philosophy and History of Science, with generous support of Robert Cohen and Jon Westling, and the organizational skills of Deborah Wilkes. The Symposium presented three ver sions of the Self from the vantages of embryology, evolution and medicine."

Streptococci are Gram-positive bacteria that cause a wide spectrum of diseases, such as pharyngitis, necrotizing fasciitis and streptococcal toxic shock syndrome, as well as rheumatic fever and rheumatic heart disease as sequelae. Antibiotics alone have not been able to control the disease and in spite of many efforts an effective vaccine is not yet available. A prerequisite for novel and successful strategies for combating these bacteria is a complete understanding of the highly complex pathogenic mechanisms involved, which are analyzed in this volume. In ten chapters, prominent authors cover various aspects including streptococcal diseases and global burden, epidemiology, adaptation and transmission, and molecular mechanisms of different diseases, as well as sequelae, vaccine development and clinical management. This book will serve as a valuable reference work for scientists, students, clinicians and public health workers and provide new approaches to meeting the challenge of streptococcal diseases.

The HLA molecules are important regulators of the immune response through mediating antigen presentation and interaction between key immune mediating cells. They are also the major histocompatibility barriers to transplantation, which is the clinical paradigm of the self versus non self concept. It is now recognized that this diverse range of gene systems involved in the control of the immune response have been shown to be important in many aspects of clinical practice. As a result many new molecular and cellular methods have been developed for identifying these genes and their polymorphisms, and immunogenetic laboratories specializing in these methods have developed to support transplantation and other clinical programs. "Immunogenetics: Methods and Applications in Clinical Practice "focuses on methods for human clinical practice. The emphasis rests on those assays which are of established or potential clinical utility and are likely to be included in the repertoire of tests provided by a routine diagnostic and service laboratory. This volume also contains several review chapters of the MHC complex, the KIR complex, the human immunoglobulin allotypes, as well as reviews of the methods for the detection of alloreactive NK cells and the detection of HLA antibodies by solid phase assays. Written in the 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 protocols, and notes on troubleshooting and avoiding known pitfalls.

Authoritative and easily accessible, "Immunogenetics: Methods and Applications in Clinical Practice "seeks to serve both the immunogenetics community and the wider scientific community with a collection of detailed information and helpful tips attained by many years of experience in the field.

During the past decade a significant international research effort has been directed towards understanding the composition and regulation of the preocular tear film. This effort has been motivated by the recognition that the tear film plays an essential role in maintaining corneal and conjunctival integrity, protecting against microbial challenge and preserving visual acuity. In addition, research has been stimulated by the knowledge that alteration or deficiency of the tear film, which occurs in countless individuals throughout the world, may lead to desiccation of the ocular surface, ulceration and perforation of the cornea, an increased incidence of infectious disease, and potentially, pronounced visual disability and blindness. 7 To promote further progress in this field of vision research, the International Conference on the Lacrimal Gland, Tear Film and Dry Eye Syndromes: Basic Science and Clinical Relevance was held in the Southampton Princess Resort in Bermuda from November 14 to 17, 1992. This meeting was designed to assess critically the current knowledge and 'state of the art' research on the structure and function of lacrimal tissue and tears in both health and disease. The goal of this conference was to provide an international exchange of information that would be of value to basic scientists involved in eye research, to physicians in the ophthalmological community, and to pharmaceutical companies with an interest in the treatment of lacrimal gland, tear film or ocular surface disorders (e. g. Sjogren's syndrome).

This volume features contributions from participants of the ESRF symposium on "Immunotherapy in 2020a "Visions and Trends for Targeting Inflammatory Diseases" held in Potsdam near Berlin, Germany, in October 2006.

The symposium presentations covered the main mechanisms of immunoregulation such as peripheral and central tolerance, epigenetic programming, immunologic memory, and regulatory networks in inflammation as well as novel experimental and clinical approaches for targeting inflammation in autoimmunity and transplantation. An important related question is how recent findings in immunological research can lead to improved diagnostics, new drugs, and better therapies. The targeting of novel pathways and immunoregulatory mechanisms, the challenge of immunologic memory for lastingly successful anti-inflammatory therapy, new approaches for adoptive T cell and polyclonal antibody therapies, and the individualization of immunomodulatory therapies are thereby topics of this volume.

Malaria remains an alarming emergency in developing countries. It is thus urgent to identify any parasite or host molecules that can serve as new affordable markers for early diagnosis of disease complications or as new targets for vector control. In this context, human and mosquito lysozymes are good candidate molecules, as their involvement in malaria has been recently reported by several independent groups. This book reviews the grounded knowledge on malaria etiology and physiopathology, as well as the current approaches for diagnosis, therapy, and vector control. In addition, the emerging evidence on the involvement of human and mosquito lysozymes in malaria from available experimental models and clinical studies is thoroughly discussed, as is the potential use of other antimicrobial peptides against malaria. Intriguingly, the contributors propose that old well-known molecules such as lysozymes might be used as new targets for cost-effective strategies to fight malaria.

The role of the immune response in both the pathology of liver disease and in the modulation ofliver injury has been the subject of intense research. This book aims to present the current understanding of the involvement of the immune response in liver disease. The first chapters examine the role of the immune response in viral infections of the liver. These viruses cause hepatitis of varying severity and it is thought that many of the mechanisms responsible for liver cell injury are immunologically mediated. In addition three of these viruses, hepatitic B, C, and D, are associated with persistent infection and chronic liver disease. The role of the immune response in viral persistence is discussed. Further chapters are devoted to the three major autoimmune liver diseases which are thought to be the result of loss of tolerance to autologous liver tissue. There has been much recent research on cellular immune responses in these diseases but knowledge of the immunological processes which lead to the breakdown of tolerance and the mechanisms of tissue damage are limited. Other research has concentrated on the identification of the antigens which are the targets of this immune response. Linkage disequilibrium between MHC alleles and autoimmune diseases has suggested a role for immunogenetic factors.

The term humanized mouse in this text refers to a mouse in which human tissues and cells have been transplanted and show the same biological function as they do in the human body. That is, the physiological properties and functions of tra- planted human tissues and cells can be analyzed in the mouse instead of using a living human body. It should therefore be possible to study the pathophysiology and treatment of human diseases in mice with good reproducibility. Thus, the hum- ized mouse can be used as a potent tool in both basic and clinical research in the future. The development of appropriate immunodeficient mice has been indispensable in the creation of the humanized mouse, which has been achieved through many years of efforts by several laboratories. The first stage on the road to the humanized mouse was the report on nude mice by Isaacson and Cattanach in 1962. Thereafter, nude mice were studied in detail by Falanagan and, in 1968, Pantelouris found that these mice have no thymus gland, which suggested that the mice lack transplan- tion immunity against xenografts such as human hematopoietic stem cells. At the Nude Mouse Workshops (organized by Regard, Povlsen, Nomura and colleagues) that were held nine times between 1972 and 1997, the possibility of creating a humanized mouse using nude mice was extensively examined. The results, however, showed that certain human cancers can be engrafted in nude mice, but unfortunately engraftment of normal human tissue was almost impossible.

Fluorescence is a very powerful tool for work at the frontier of cell biology, photobiology and bioinstrumentation. The stated aim of the workshop was to highlight the significance of fluorescence work for the understanding of cell and tissue physiology, physiopathology and pharmacology, particulary in terms of the analytical use of fluorescent probes in oncology. In the organization of the workshop a multidisciplinary approach was selected. The purpose of the Advanced Research Workshop (ARW) was to bring together researchers in the various disciplines of tissue optics, imaging, microspectrofluorometry and state of the art probes, in order to explore the full benefits that can be derived in biomedicine through the convergence of these approaches. When applied to in vivo and in situ studies, fluorescence and related optical methods enable us to explore within tissues, cells and organelles photon effects previously understood only in solution photochemistry. Processes which can be studied at the molecular level by photophysics, photochemistry and physical chemistry can be evaluated in living tissue by fluorescence spectroscopy and imaging at the intracellular level in terms of structure and function. Thus, fluorescence adds a new dimension to cell biology and physiology. This approach is now supported by a full and versatile, rapidly growing armamentarium of new selective probes for organelles, enzymes, cations, cytoskeleton and metabolic control.

"Recent studies have discovered new known and characterized cytokines, allowing for advancement in miniaturization of micro-analytical methods as well as the extensive development of bio-informatics and nanotechnology. These advancements have allowed researchers to reduces sample sizes making for more accurate determinations then previously possible. In Cytokine Protocols: Second Edition, expert researchers in the field detail many of the methods which are now commonly used to study cytokines. These methods and techniques for studying cytokines include historical importance and the importance of researchers using bioassay, quantification, and characterization of cytokine related RNAs, posttranscriptional modifications of RNA, either naturally or artificially, and observations at the protein level. Written in the highly successful Methods in Molecular Biology (TM) series format, the chapters include the kind of detailed description and implementation advice that is crucial for getting optimal results in the laboratory. Authoritative and practical, Cytokine Protocols: Second Edition seeks to aid scientists in furthering the crucially important advancement of cytokine research."

Biomedical scientists widely acknowledge that individuals' immune respon siveness is important in resistance to infections by microorganisms, including fungi. Because of the devastating acquired immunodeficiency syndrome (AIDS) epidemic, caused by the human immunodeficiency retrovirus, it is now accepted that suppressed immune responses, especially cellular immu nity, are important contributors to increased individual susceptibility to opportunistic infections-including infections caused by fungi which were at one time thought to be very lowly or nonpathogenic. Within the last few years, there has been an almost explosive increase in interest and studies concerning the nature and mechanisms of the immune response to fungal infections. Many immunologists who are not well versed in mycology have begun to study the nature and mechanisms of antifungal immunity using a wide variety of newer as well as more conventional immunologic technologies, both in vivo and in vitro. Up to the 1980s, however, there was little interest among basic immunologists concerning fungal immunity. This situation has changed dramatically in the past half decade, mainly because of AIDS."

Cancer care is undergoing a radical transformation as novel technologies are directed toward new treatments and personalized medicine. The most dramatic advances in the treatment of cancer have come from therapeutics that augment the immune response to tumors. The immune checkpoint inhibitors are the best-known and most highly advanced examples of Immune Therapeutics targeting tumor cells and include approved antibody drugs directed at the cell surface proteins CTLA4 and PD-1. These are now considered foundational treatments for several solid tumor indications, and that list of indications is growing quickly. More broadly, antibodies have become workhorse molecules across the entire immunotherapy landscape. Antibodies to novel targets modulate the activity of diverse immune cell regulatory proteins. Engineered antibodies can induce tumor cell death or expose tumor cells to poisonous toxins (ADCC and ADC, respectively). Bi-specific antibodies can engage multiple tumor targets simultaneously, or can redirect lymphocytes to attack tumor cells. The antigen-binding domains within antibodies can be spliced onto cell stimulatory domains and transduced into T cells or NK cells, creating remarkable tumor-specific cellular therapeutics (CAR-T, CAR-NK). Beyond antibody-based therapies there are highly diverse and differentiated technology tool kits being applied to immunotherapy. Small molecule drugs are being developed to attack the tumor microenvironment, novel tumor vaccine approaches are showing great promise, patient lymphocytes are being isolated, expanded and reintroduced to patients, gene-editing techniques are becoming widely deployed, and a vast number of new tumor targets, and mutated tumor proteins (neoantigens), are being discovered. The past decade has seen unprecedented success in the treatment of diverse cancers. The authors of this volume have been asked to not only review progress to date, but importantly, to look ahead, and anticipate the evolution of cancer treatment across diverse Immune Therapeutic approaches. Our hypothesis is that the advances we are seeing across the immunotherapy landscape will further evolve and synergize, leading us finally to outright cures for many cancers.

Most complex biological systems, such as enzyme pathways, are effec tively controlled near the beginning of the process. There is increasing evidence that the same is true for the immune system, with the initial interactions between antigen, antigen-presenting cells, and T cells hav ing a paramount influence on the ensuing events. Thus, analysis of the early stages of the immune responses has been a preoccupation of many immunologists. This has been considerably aided by the capac ity to expand these early events, and 'immortalize' them as clones of T cells, for detailed analysis. The discovery by Morgan, Ruscetti, and Gallo (Science 193, 1007, 1976) of T-cell growth factor (now termed interleukin-2 or IL-2) has had a major impact in immunology that is far from over. The greater ease of handling murine tissues experimentally, with the availability of more precisely defined reagents such as inbred strains, has meant that, to date, most of the work on long-term T-cell cultures has been per formed in the mouse, as summarized by Fathman and Fitch (eds., Iso lation, Characterization and Utilization of T Lymphocyte Clones, Aca demic Press, NY, 1982). However, the limitations of working with human tissues are counterbalanced by the great long-term importance of understanding disorders of human immune regulation, especially since it is becoming evident that these are far from rare. Immune deficiencies such as agammaglobulinemia and T-cell deficiencies are not common, but immune hyperresponsiveness occurring in allergy and allergiC diseases (e. g."

The development of radioimmunoassay (RIA) by R.S. Yalow and S.A. Berson in 1959 opens up a new avenue in ultra sensitive analysis of trace substances in complex biological systems. In recognition of the enormous contributions of RIA to basic research in biology and to routine clinical tests in laboratory medicine, R.S. Yalow, the co-developer of RIA, was awarded, in 1977, the Nobel Prize for Medicine and Physiology. The basic principle of RIA is elegantly simple. It is based on a specific, competitive binding reaction between the analyte and the radio-labeled analog of the analyte for the specific antibody raised to the analyte. The combination of high specificity and affinity of an antibody molecule makes it a very versatile analytical reagent capable of reacting specifically with analytes at a very low concentration in a complex solution such as serum. The sensitivity of RIA is provided by using a radioactive tracer."

This monograph reviews information published since 1997 on the group B coxsackieviruses (CVB), a large and important group of human enteroviruses. The CVB were discovered in the mid-20th century, during the search for other poliovirus types, and within a very few years of this discovery, the CVB had been implicated as causes of human myocarditis and pancreatitis. The study of the CVB is still inextricably linked with the fate of their well-known relatives, the polioviruses, for as poliovirus eradication proceeds around the world, the CVB emerge more prominently as the enteroviruses best suited for continuing studies in enteroviral molecular biology as well as understanding the mechanisms underlying enteroviral pathogenesis. This volume reviews and presents modern views on the spectrum of CVB biologies, from interaction of the virus with its receptor through replication, speciation, and induction of disease.

"Mycobacterium tuberculosis" is one of the most notorious pathogens on earth, causing the death of approximately 1.5 million people annually. A major problem in the fight against tuberculosis is the emergence of strains that have acquired resistance to all available antibiotics. One key to the success of "M. tuberculosis" as a pathogen is its ability to circumvent host immune responses at different levels. This is not only a result of the special makeup of "M. tuberculosis" in terms of genetic diversity and DNA metabolism and its possession of specialized secretion systems, but also of its ability to hijack the host s innate immune defence mechanisms.

In this volume, researchers from different disciplines provide a topical overview of the diverse mechanisms that contribute to the virulence of "M. tuberculosis," ranging from their genetic, metabolic and molecular makeup, as well as the complex strategies these bacteria utilize to escape immune destruction within infected hosts."

The fifth of the annual research conferences of the American Institute for Cancer Research was held September l-2, 1994, at the L'Enfant Plaza Hotel in Washington, DC. Appropriately, in view of current directions in research, the theme was "Diet and Cancer: Molecular Mechanisms of Interactions." This proceedings volume contains chapters from the platform presentations and abstracts from the poster session held on the end of the first day. The subtopics for the tl;rree sessions held were "Retinoids, Vitamins A and Din Cancer Prevention and Therapy," "Choline and Lipids: Signal Transduction, Gene Expression and Growth Regulation," and "Dietary Factors and Regulation of Oncogenes, Growth and Differentiation. " A general overview on vitamins A and D emphasized that A and D, in addition to their established roles in vision, reproduction, and bone mineral homeostasis, may play significant roles in regulating cell function. Vitamin A metabolites, trans-retinoic acid and 9-cis-retinoic acid, regulate growth and differentiation. Furthermore, vitamin A deprived animals were more susceptible to both spontaneous and carcinogen-induced tumors. Epidemiological studies showed a correlation between low A intake and higher incidences of certain types of human cancers. Conversely, all-trans retinoic acid is useful in treatment and control of certain types of cancer. Physiologically, Vitamin D is converted to the active form, l,25-dihydroxyvitamin D (VD). VD regulates hormone production and secretion, myocardial contractility, vascu 3 3 3 lar tone, and growth inhibition and differentiation."
