When I entered the field of allergy in the early 1970s, the standard textbook was a few hundred pages, and the specialty was so compact that texts were often authored entirely by a single individual and were never larger than one volume. Compare this with Allergy Frontiers: Epigenetics, Allergens, and Risk Factors, the present s- volume text with well over 150 contributors from throughout the world. This book captures the explosive growth of our specialty since the single-author textbooks referred to above. The unprecedented format of this work lies in its meticulous attention to detail yet comprehensive scope. For example, great detail is seen in manuscripts dealing with topics such as "Exosomes, naturally occurring minimal antigen presenting units" and "Neuropeptide S receptor 1 (NPSR1), an asthma susceptibility gene." The scope is exemplified by the unique approach to disease entities normally dealt with in a single chapter in most texts. For example, anaphylaxis, a topic usually confined to one chapter in most textbooks, is given five chapters in Allergy Frontiers. This approach allows the text to employ multiple contributors for a single topic, giving the reader the advantage of being introduced to more than one vi- point regarding a single disease.

Our understanding of the humoral (B-cell) immune system has increased dramatically in recent years. IVIG Therapy Today highlights new third generation IgG products for intravenous use. Commercial gammaglobulin preparations first appeared in the early 1980s, and, since that time, therapeutic applications of intravenous immune serum globulin, or IVIG, have been developed at a rapid pace. Uses include replacement therapy in patients with antibody deficiencies and immunoregulatory/immunomodulatory agents in treatment of the autoimmune diseases. In two major parts, IVIG Therapy Today first presents reviews of primary and acquired humoral/B-cell immune deficiencies, featuring IVIG as replacement therapy, then explores the immunomodulatory effects of IVIG in autoimmune disorders.Chapters cover a wealth of timely background information and clinical applications, including: IVIG replacement therapy in primary immune deficiency syndrome * IVIG in prevention and treatment of neonatal bacterial infections * potential use of monoclonal antibodies in neonatal infections * immune deficiencies in chronic lymphocytic leukemia and multiple myeloma * IVIG in treatment of children with idiopathic thrombocytopenic purpura and autoimmune cytopenias * IVIG therapy in neonatal isoimmune thrombocytopenic purpura and alloimmunization thrombocytopenias * IVIG in Kawasaki disease and other autoimmune diseases * use of intravenous serum globulin in patients with antiphospholipid antibodies and recurrent pregnancy losses * IVIG in neurologic diseases * IVIG in asthma management. Dr. Ballow has assembled an outstanding collection of state-of-the-art information, making IVIG Therapy Today an essential guide for specialists in clinical and experimental immunotherapy.

This work is concerned with Cystic Fibrosis (CF), the most common fatal genetic disease in the Caucasian population. The decade of the 1980s was one of spectacular progress in understanding the genetic and molecu lar basis of CF. The research breakthroughs of the decade began with the first fundamental insights, published in 1981-1983, into the basic cellular pathophysiology of CF with demonstrations of altered ion transport in spe cialized exocrine epithelial tissues (1-3). Research progress shifted into a triumph of "reverse genetics," using restriction-fragment-Iength polymor phism DNA technology (4), with the localization of the CF gene to a region of chromosome 7 (5-7). Understanding, accelerated by an explOSion of in vitro methodologies for epithelial cell culture and transformation, allowed and physiological studies (8-11); these focused, controlled biochemical with increasing precision, on the molecular pathology of distal steps in the regulatory pathways for epithelial ion transport (12-19). Finally, the "end of the beginning" occurred in late 1989 with one of the great achievements of molecular genetics, the isolation and cloning of the CF gene (20). As a result, we now have a CF gene product, the cystic fibrosis transmembrane regulator (CFfR), possessing predicted amino acid sequence, suggested tertiary structure, and possible transmembrane transport function (21). These amazing developments have set the stage for the next round of advances, which surely will include: 1.

Here is an up-to-date review of important new methods and results in anti-idiotypes, receptors, and molecular mimicry. It begins with a discussion of the theoretical background of the anti-idiotypic network, it's role in the regulation of immune response, and the physical characteristics of anti-idiotypic antibodies. It then goes on to explore many exciting applications in such areas as insulin action, thyroid cell function, the neurosciences, cardiology, virology, pharmacology, and reproduction.

The study of immunology encompasses a vast and ever-growing body of information that in some way or other incorporates most areas of medical biological research. As the body of information in the medical sciences continues to increase its rate of expansion, one of the greatest challenges to investigators will be to integrate this information in a manner that is intellectually fruitful and productive. Considering the intended scope of this text, we could not pretend to have gone too far toward achieving such an integration--and considering the pace of change, in its very best form a measured approximation of such lofty goals might be the most we could hope for. Nevertheless, in these pages we have sought to produce a collection of information that is at once concise and up-to-date regarding areas where important developments are impacting on the way we understand the vertebrate immune system. In addition, although the information is geared toward advanced study, we have discussed some basic elements and concepts that we hope make the text a useful resource for both the immunologist and the nonspecialist. The intention is to provide the researcher, clinician, or advanced undergraduate student with a brief ov- view of specific components of the immune system, and to provide a place from which to begin further detailed study if necessary. To this end, we made every effort to supply extensive referencing--although limitations in space prevented exhaustive or complete referencing in some cases.

Whereas plant and insect infections are commonly caused by fungi, only a small minority of the vast diversity of fungal species is pathogenic to humans. Despite this, fungal infections cause considerable morbidity and mortality worldwide. This volume is dedicated to the biology, clinical presentation and management of invasive fungal infections. Major pathogenic fungi are introduced by world-leading experts and the basic principles of fungal virulence are reviewed in the light of new results and experimental technologies that offer unprecedented insights into invasive infections caused by Aspergillus, Candida, Cryptococcus, Pneumocystis and Mucorales. In parallel, the clinical presentation of invasive fungal infections and current approaches to their diagnosis and treatment are summarized to provide an overview of human pathogenic fungi, linking pathogen biology to the clinical presentation of disease.

We are celebrating this year the hundred years anniversary of allergen-specific immunotherapy. In 1911 Leonard Noon published his seminal work "Prophylactic inoculation against hay fever" describing his attempts to achieve active immunity against "grass pollen toxin" by administering increasing doses of grass pollen extract before the grass pollen season to allergic patients. Although it was unknown at that time that allergy represents an immunological hypersensitivity disease, the treatment was effective and many observations made by Noon remained valid until today. Today allergen-specific immunotherapy is well established as the only allergen-specific and disease-modifying treatment for IgE-mediated allergies and has long-lasting effects. In fact, more than 25% of the population suffer from IgE-mediated allergies which therefore represent a major health burden of our society, particularly because untreated allergy often progresses to severe disabling forms of disease, such as asthma and sometimes kills sensitized people through anaphylaxis.

ince the early 1980s, the HIV epidemic has been raging within the S 1 United States and around the world. Drug therapy for HIV infection has not been curative, prompting the search for alternative strategies to control HIV infection within infected persons. One potential alterna tive to drug therapy is a developing medical technology termed gene therapy. 2 Gene therapy involves introducing genetic elements into popu lations of cells in order to correct or prevent a pathologic process. A large number of gene therapy strategies have been developed in an at tempt to inhibit HIV expression and spread. These strategies fall into two general categories, genetic modification of cells in order to elicit an immune response against HIV and genetic modification of the target cells of HIV infection in order to block HIV expression and reproduction. In the first strategy, termed genetic immunotherapy by some, genetic material encoding HIV proteins is introduced into patient's cells in order to stimulate a cellular immune response above and beyond 3 5 that stimulated by the viral infection itself. - Two general genetic im munotherapy strategies have been developed. Genes encoding HIV pro teins have been directly injected into the dermis or muscle tissue of patients. These genes have been encoded in plasmids or viral DNA and have been injected either in the form of naked DNA or complexed with lipids."

Leading clinical experts survey the latest information available on the key rheumatic and allergic issues that physicians face in treating the HIV-infected patient. The physicians focus on the rheumatologic and dermatologic manifestations of HIV-1 infection, which include arthritis, myopathies, vasculitis, sicca syndrome, other autoimmune phenomena, and psoriasis. They also examine the question of allergic reactions in HIV patients, including drug hypersensitivity, with special attention given to adverse reactions to trimethoprim-sulfamethoxazole, the most frequently prescribed anti-infective. Practical advice for the diagnosis and treatment of these problems is given in full.

In recent years, epigenetic approaches to existing scientific problems have offered many new and exciting perspectives. This book focuses on epigenetic approaches to study asthma and allergy research. The authors briefly review cellular factors, immune signaling, and inflammatory pathways in allergy and asthma, as well as genetic influences in the pathogenesis of atopic disorders. Diseases that have been clearly linked to an epigenetic dysregulation will be discussed, as well as the role of epigenetics in the origin of complex diseases. The authors will examine the impact of environment factors in the predisposition to atopic disorders, and they will also describe the major unanswered questions and future perspectives of an exciting new field that studies allergic diseases from the epigenetic point of view.

In the two decades since the elusive "slow reacting substance of anaphylaxis" (SRS-A) was identified as a product of the action of the 5-lipoxygenase enzyme on arachidonic acid, it has been well established that the leukotrienes are key mediators of both alIergy and inflammation. Their release by alIergen or other challenge has been demonstrated in the lungs of asthmatic subjects, and measurement of urinary leukotriene concentrations in such patients has been shown to be a valuable, non invasive indicator. Significant progress has been made towards the characterization of the leukotriene receptor subtypes, exemplified by the cloning of the LTB4 receptor earlier this year. Coupled with this there has been a continued elucidation of signal transduction mechanisms underlying receptor activation. Consequent upon these advances has been the development of potent antagonists of the CysLT receptor, J and both these and inhibitors of leukotriene biosynthesis have entered clinical practice in the therapy of asthma. In this clinical setting antagonists of the CysLTJ receptor have been shown to be an effective therapy in chronic asthmatics, against antigen- and exercise-induced bronchoconstriction, and in aspirin-intolerant asthmatics. The advent of this new class of agents promises to change the way in which asthmatic patients are currently treated."

Skin diseases caused by aquatic organisms are continually on the increase owing to the great number of people who now converge on the hydrosphere for holidays, sports and professional activities. Aquatic skin diseases are no longer only a seasonal affliction but can be observed at any period, thanks to the tourist boom promoting aquatic holidaymaking throughout the year. This book aims to contribute to the knowledge of some aquatic animals that have only developed a poisonous apparatus to protect themselves and adapt to their environment, as well as of the various clinical pictures induced by different pathogenic mechanisms. Besides the afflictions caused by biotoxins, skin reactions to microscopic organisms present in seawater, freshwater, swimming pools and aquariums are described, together with some non-biotic forms induced by direct contact with salt and freshwater. A better knowledge of the aquatic environment may help people to enjoy this enthralling habitat at lesser risk.

Progress in Basic and Clinical Immunology is a result of the 14th European Immunology Meeting - EFIS 2000, held in Poznan, Poland, on 23-27 September 2000. EFIS 2000 gathered over 1400 immunologists from all over the world. It was an exceptionally memorable meeting for a number of reasons: 1) it was held in the last year of the century and the millennium, thus provoking conclusions of past achievements of immunology and projections for the future; 2) it was held in Poland, a country that is a symbol of struggle for freedom for a large number of scientists originating from the 'Eastern Bloc' countries; and 3) EFIS celebrated its 25th anniversary at this occasion. This comprehensive volume contains 62 chapters grouped into 11 sections: T-cells, Immune Receptors, Antigen Presentation/Dendritic Cells, Cytokines, Immunodeficiencies, Autoimmunity, Allergy/Inflammation, Immunotherapy, Vaccines, Tumor Immunology, and Cancer Immunotherapy.

During the last decade, rapid progress has been made in the area of microbial immu- nity. New conceptual frameworks have emerged with regard to the processing and presen- tation of peptides and nonpeptide antigens from microbes, especially bacteria, to T cells in the context of classical MHC class I and nonconventional MHC I molecules. Experimen- tal models have been instrumental in defining some of these pathways for generating pro- tective immune responses against microbes, which form the basis for the design of new vaccines. New evidence has stressed the importance of innate immunity in microbial in- fections. The concept of dichotomy within T helper cells has revealed the role of these cell types in resistance and susceptibility to microbial-mediated pathology. These latest devel- opments in microbial immunity are discussed in this volume. Natural killer cell development is known to be regulated by the presence of MHC class I antigens. Receptors for MHC class I molecules on NK cells have been discovered. Interaction of these receptors with their specific ligands leads to inhibition of cytotoxicity. Vinay Kumar and colleagues review NK cell differentiation and ontogeny, and functions of NK cells in experimental animals. Lewis Lanier discusses the role of a newly discov- ered molecule, DAP 12, in KIR and other receptor-mediated signal transduction in NK cells. Eric Long describes the regulation of immune response by inhibitory receptors.

Allergy is one of the major health problems of most modern societies. Allergic diseases have increased in prevalence during the last decades; the reasons for this increase are unknown, there are only hypothetical concepts for explanation. The series New Trends in Allergy now covers five volumes origin- ing from special international symposia, started in 1980 and held every 5 years, which highlight specific areas of progress in allergy research and practice. The idea behind the 5-year interval between these s- posia is that real new developments do not occur very often and c- tainly not every year. The contents of this book focus on specific areas where progress in allergy research has shown fascinating developments, such as: - Elucidation of the complex genetic basis of atopy - The influence of environmental pollutants as well as natural biolo- cal environmental factors on allergy - Gene-environment interactions in the development of allergy - Psycho-neuro-immunological aspects of allergic sensitisation and disease - The nature and function of dendritic cells in skin and mucous m- branes - Interactions between lymphocytes and effector cells, such as mast cells, eosinophils and neutrophils - Allergen carriers, allergen release and bioavailability, allergen str- ture - Atopic eczema - Asthma and rhinoconjunctivitis - Food allergy and anaphylaxis - Pharmacotherapy - Unspecific (e. g.

This monograph covers the entire field of blood group serology, with its main emphasis on the chemical and biochemical basis of blood group specificity. Full consideration is given to molecular biology investigations, in particular to studies on the structure of blood group genes and the molecular biological basis of alleles and rare blood group variants, whereby relevant literature up to the year 2000 is covered. The text is supplemented by numerous illustrations and tables, and detailed reference lists.

Progress in basic and clinical immunology within the last two decades has provided profound insight into the immune system and its role in preventing endogenous and exogenous damage. In contrast, disbalances within this system can result in autoimmune disorders which may affect diverse organs and result in distinct clinical pictures. In many of these, however, the individual etiopathogenetic mechanisms are poorly understood and even more their clinical symptoms are hard to treat. The book offers insight into basic mechanisms of autoimmune disorders. It includes neurological, gastrointestinal, ophthalmological and skin diseases as well as current and future therapeutic options including immunomodulatory drugs and different vaccination strategies. By addressing diverse organ systems, both singular and shared features are elaborated. Thus an exchange of ideas is intended across research on single organ systems within a truly interdisciplinary setting.

Antibodies are crucial to the fine specificity of the immune system. An effective functioning of these molecules requires interaction with immune cells. Receptors for antibodies, Fc receptors, provide this critical link between the humoral and cellular branches of the immune system. This book presents a comprehensive overview of the different Fc receptors currently recognized. The first part of the book contains state-of-the-art overviews on the biological role of FcR. The latest information on FcR heterogeneity, FcR physiology, FcR-ligand recognition, their crucial coordinating role in immunity, interactions with other immunoreceptors, and the role of FcR in immunoglobulin transport and catabolism are discussed. The clinical importance of FcR is developed in the second part of the book. The well-recognized roles of FcR in allergy, inflammation, infectious diseases, autoimmune disorders, and immunotherapeutic importance are reviewed. The information in this book is easily accessible and should be helpful for researchers and clinical specialists as a convenient overview of the field, as well as a comprehensive introduction for students starting in this area of research.

Focusing on the rapidly increasing interaction between biotechnology and advanced fiberoptics/electronics, Biosensors with Fiberoptics emphasizes the three major phases of the developmental process from concept to marketplace: research, development, and applications. With contributions by leading experts directly involved in key areas of this exciting, fast-paced field, the book describes novel biosensor technologies and such current and potential applications as: chemical sensing * fluorescent labels * evanescent-wave biosensors and immunosensors * clinical applications * immunoassay kinetics * luminescence * monitoring of environmental toxins. Researchers and clinicians in a broad spectrum of disciplines will find Wise and Wingard's Biosensors with FIBEROPTICS an extremely practical, up-to-date reference text.

It has been said that the development of vaccines against a variety of infectious diseases is among the greatest triumphs of immunology. Indeed, several pathogens have lost their horror through the availability of effective vaccination measures. Unfortunately, this does not hold true for the pathogens dealt within this volume. Malaria, schistosomiasis, leishmaniasis, leprosy, and tuberculosis together are prevalent in more than 100 countries, and over 400 million persons suffer from these diseases. It is becoming increasingly clear that the failure to control these infections in a satisfactory way is directly related to the complexity oftheir interactions with the immune system. These agents have lived with their hosts for long enough to give both-host and parasite-ample opportunity to develop a highly sophisticated interrelationship. The central role of T lymphocytes both in acquired resistance to and pathogenesis of these microbes is well appreciated. In the beginning it may have been thought that acq uired resistance against infectious agents is nothing but another aspect of the immune response, studied with soluble and particulate antigens. This simple concept has gradually changed, and it has become clear that the viability not only of the immune cells but also of the 'antigens' adds another dimension to the game. Several achievements in cellular immunology and molecular biology have now made it possible to better understand at least some mechanisms in this intricate interplay.

Carbohydrate as the primary product of photosynthesis has a vital role in the maintenance of life on this planet. Until relatively recently, interest in complex carbohydrates focussed on their structural role in the extracellular matrix/ cell wall of animal, plant, and microbial cells and on their role as energy sources (e.g., starch and glycogen) and struc tural components (e.g., cellulose) in natural products. There was, however, indirect evidence that carbohydrates could play an informational role; this evidence was from the find ing last century that plant lectins caused specific agglutina tion of certain animal cells and, more recently, that the agglutination was mediated by interactions between the plant lectin and cell surface carbohydrates. It is now clear that endogenous carbohydrate binding proteins are important in cell-cell recognition phenomena in animal systems. Recently, impressive evidence has been presented that complex oligosaccharides, derived from cell walls, are also important in plant recognition events, for example in signalling the defence mechanisms of a plant to respond to attack by insects and microbial pathogens."

Phagocytic cells and complement are probably the most important components of host defense against bacteria which, after overcoming the mucosal and epithelial barriers, multiply in the subepithelial tissue and may threaten to disseminate and invade the blood stream and different organs. Questions concerning the factors which regulate the interactions of the bacterial cell with host defenses are a challenge to research and lead to practical applications for the prevention, treatment and diagnosis of infectious diseases. The questions of expression and regulation of virulence related bacterial genes and gene products, the specific mechanisms of defence reactions by complement and phagocytic cells, their mutual interactions with bacteria and especially bacterial surfaces are focused. Considerations on how to translate this knowledge into the management of infectious diseases are also included.

The development of innovative molecular techniques such as pulse-field gel electro phoresis, cDNA subtraction libraries and chromosome hopping libraries coupled with the increasing popularity in the prospect of sequencing mammalian genomes, has triggered a resurgence of interest in finding and characterizing genes that playa role in modifying immune processes and diseases. Genetically defined strains of mice (e. g., inbred strains and recently derived stocks of wild mice) provide ideal models for examining the genetic control of diseases as a result of their syntenic relationship with man in genetic composition as well as linkage conserva tion. Due to the relative ease of producing a specific genotype via appropriate breeding schedules, murine models may provide the only hope for unravelling those complex disease processes under mUltigenic control. This issue of CTMI is a collection of papers on the characterization and mapping of genes involved in mutations and dysregulated immune responses which produce disease phenotypes. These papers were presented at a workshop which was devoted to examining reverse genetic approaches at localizing, cloning and characterizing genes involved in a variety of developmental, autoimmune, neoplastic and infectious disease processes. In the first of three sections, a series of papers outline the most currently used methods of mapping and isolating genes whose products are unknown. The papers, following, are devoted to specific gene systems whose dysregulation is likely to produce mutant or disease phenotypes."
