Welcome to the City of Groningen, the center of the North of the Netherlands. Groningen is proud of the long lasting tradition of scientific symposia organised by the Sanquin Blood Bank. These Sanquin International Symposia on Blood Transfusion have become a true traditional event in Groningen, marking the early academic year and have contributed to the specific reputation of Groningen and its University in the scientific field of Transfusion Medicine. The growing tradition has also contributed to initiatives of both University, Province and the City of Groningen to bring science and industry together - BioMedCity Groningen. Such repu- tion does not just happen, but is the result of creative and scientific leadership, of vision and an open mind, to explore in a team spirit horizons. Groningen is particularly proud of this reputation thanks to its leadership, the Sanquin Blood Bank North-East. This year in particular the theme chosen some two years ago is extremely timely as it illustrates the activities and scientific interest of an integrated team which includes our regional Sanquin Blood Bank North-East and fits in the City initiatives within the concept of BioMedCity, Groningen.

This book stems from a conference held at Magdeburg-Herrenkrug, Germany, in November 1996 on "Cellular Peptidases in Immune Functions and Diseases. " This sympo- sium was designed to bring together scientists from diverse areas of expertise to discuss issues of newly identified relevance of proteolytic processes and their role as molecular regulators in the immune system and in diseases. The meeting was organized by the Son- derforschungsbereich 387 of the Deutsche Forschungsgemeinschaft "ZelluHire Proteasen, Bedeutung fiir Immunmechanismen und entziindliche Erkrankungen," which links re- search groups from the Otto von Guericke University Magdeburg and the Martin Luther University Halle. It has become clear during the last decade that proteolysis, the processing and degrada- tion of peptides and proteins, has to be considered as a special level of epigenetic control of practically all processes of life and-an understanding dating from the last three years or so--also of cell death or apoptosis. There is also increasing evidence that proteolysis does play a crucial role in all areas of immune functions as well as in inflammatory and neoplastic diseases. Cellular proteases have central functions in natural (nonspecific) as well as acquired in the cognitive phase (antigen processing and presen- (specific) immunity. They are involved tation), in the activation phase (e. g. , generation and processing of cytokines, function of CD26, CD 13, processing of transcription factors) as well as in the effector phase of the im- mune response (e. g. , complement system, granzymes, elastase, proteinase 3.

This detailed book serves as a systematic examination of the analytical methods to study the transcription factor NF- B in physiology and disease. It provides an up-to-date guidebook to navigate both conventional and highly specialized methods to detect and analyze the different signaling pathways of NF- B activation and contextualize them within organismal physiology and disease pathogenesis, using genetic and biochemical techniques and some of the most advanced computational and systems biology methods. Additionally, the volume includes several examples of approaches utilized by leading experts in the NF- B field to analyze and modulate NF- B signaling in specific physiological and disease contexts, along with some of the most promising approaches to pharmacologically target the NF- B pathway in human disease. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, NF- B Transcription Factors: Methods and Protocols is an up-to-date guide intended for both basic and translational scientists who are working in the dynamic NF- B field.

This book provides a lucid summary of behavioral, neural and endocrine regulation of immune responses and of the effects of immune system activity on neural and endocrine functions and behavior. The underlying premise is that the brain and immune system represent a single, integrated system of defense. The discussion includes such topics and stress induced modulation of innate resistance and adaptive immunity in influenza viral infections.

There is increasing evidence that the CD1 system has been conserved throughout mammalian evolution and is capable of presenting structurally diverse diacyglycerol, sphingolipid, polyisoprenol and lipopeptide antigens. These features of CD1 antigen presentation systems now point to a new and expanded view of the natural function of ab T cells, which involves surveillance of both the protein and lipid components of target cells. Further, cellular systems that were previously considered to have functions in lipid metabolism can now be studied in context of their immunological functions. This volume provides a comprehensive discussion of these basic aspects of CD1 biology and summarizes the most recent research into the role of CD1 in infectious, autoimmune, allergic and neoplastic disease.

Aegean Conferences is an independent, nonprofit, educational organization directed and managed by the scientific community. The board is made up of nine researchers/scientists in various disciplines from Harvard, Brown, University of Pennsylvania, UCSD, Princeton, Biovista and the Foundation for Biomedical Research Academy of Athens. The board both invites and approves unsolicited proposals for Conferences in all fields of Science, Engineering, Arts, and Humanities. The purpose of the Conferences is to bring together individuals with common interests to examine the emerging and most advanced aspects of their particular field.

This volume will include mini-reviews derived from work to be presented at the Aegean Conference: Second Crossroads between Innate and Adaptive Immunity, in Crete, Greece, June 17-22, 2007. This meeting is designed to serve as a forum to discuss the most recent progress in complement research as it pertains to human disease pathogenesis and therapeutics. The rapid pace of development in complement basic research and the advent and application of new experimental approaches in this field have now allowed us to take an integrated view of the in vivo biology of the complement system. The availability of new reagents (e.g. synthetic and recombinant inhibitors) and animal models (e.g. transgenic and knockout mice) has enabled us to address, in an in vivo setting, its involvement in various pathophysiological conditions. Such studies are shedding new light on the pathogenetic mechanism of complement-related diseases such as autoimmune diseases and inflammatory tissue damage as well as defining new areas of high interest such as the developmental biology of complement. They also provide the basis for developing new therapeutic strategies for these diseases through manipulation of in vivo complement activity. This volume will serve as a resource where the latest development in these specific areas will be discussed in a more focused and detailed manner.

Natural killer (NK) cells have been at the forefront of immunology for two decades. During that time, a great amount of information about these cells has been obtained. They are important in antiinfectious and antitumoral defense and shape the adaptive immune response. In addition, they can act as immunoregulatory cells. In recent years, the therapeutic potential of NK cells in cancer immunotherapy has become increasingly evident. This book describes in detail current knowledge about NK cells and covers a broad range of NK cell-related topics, including those that are not frequently reviewed, e.g. NK cells and allergy or NK cells and skin diseases.

Origins of Human Socialization introduces a new concept on the origins of basic human instinct. The book combines the three disciplinary approaches, including neuroscience, paleoanthropology and developmental psychology as an intertwined foundation for prosocial behavior. It argues that humans have the basic brain mechanisms for prosocial activity, offering new insights into more sophisticated social behavior. It also examines both visual and auditory systems in both humans and animals to explain the evolution of social interactions. Written by world-renowned researcher Dr. Donald Pfaff, this book is the first to explore why we have basic social instinct and how it works. For centuries, researchers have argued over the foundations of human behavior in society. Anthropologists point to transitions from hunter/gathers to urban dwellers leading to human domestication. Developmental psychologists highlight social competences in babies. Neuroscientists focus on specific genetic and neurochemical mechanisms that attribute to social behavior. This book brings all of these important areas together in an interdisciplinary approach that helps readers understand how they are linked.

About 7 million people worldwide are suffering from various inherited neuromuscular diseases. Gene therapy brings the hope of treating these diseases at their genetic roots. Muscle Gene Therapy is the only book dedicated to this topic. The first edition was published in 2010 when the field was just about to enter its prime time. The progress made since then has been unprecedented. The number of diseases that have been targeted by gene therapy has increased tremendously. The gene therapy toolbox is expanded greatly with many creative novel strategies (such as genome editing and therapy with disease-modifying genes). Most importantly, clinical benefits have begun to emerge in human patients. To reflect rapid advances in the field, we have compiled the second edition of Muscle Gene Therapy with contributions from experts that have conducted gene therapy studies either in animal models and/or in human patients. The new edition offers a much needed, up-to-date overview and perspective on the foundation and current status of neuromuscular disease gene therapy. It provides a framework to the development and regulatory approval of muscle gene therapy drugs in the upcoming years. This book is a must-have for anyone who is interested in neuromuscular disease gene therapy including those in the research arena (established investigators and trainees in the fields of clinical practice, veterinary medicine and basic biomedical sciences), funding and regulatory agencies, and patient community.

Subsequent chapters focus on different classes of microorganisms and psychiatric illnesses and emphasize diverse research approaches ranging from preclinical models to therapeutic interventions.

The present volume focuses on microbial invasion strategies of pathogen uptake. An accompanying volume (Vol. 5) in the series presents the phagocytic process from the viewpiont of the host cell.
This field of study is growing rapidly after a somewhat slow start over recent decades. This collection of invited chapters attempts to reflect current research and brings together cell biologists, microbiologists, and immunologists wiht disthemes, hopefully like a symphony rather than a boring catalogue. It will be evident that editorial bias favors intracellular parasitism and medically important organisms. The neutrophil is far more than a supporting player to the macrophage and some attempt is made to remind the reader of some of its unique skills. To retain a manageable size, the emphasis is on relatively early events such as mutual recognition, cell entry, and response, rather than on longterm changes in gene expression by either host cell or pahtogen. Viruses are excluded not because of lack of importance but because of somewhat different research approaches, although it is becoming increasingly clear that large viruses (e.g. "Vaccinia") and "Listeria monocytogenes," share common strategies in invasion and intercellular spread.
