Immunity studies in sharks over the past three decades have produced some remarkable discoveries. If one message rings true, it is that alternative animal model systems, such as sharks and their relatives, have contributed very substantially to a better understanding of the development evolution of our own immune system.Immunobiology of the Shark describes the cellular, genetic, and molecular specifics of immune systems in sharks. Diverse approaches were employed to study the immunobiology of the shark from basic microscopic observations to detailed genome annotation. The book also raises a series of fascinating questions, which can be addressed experimentally using today’s technology. This book will be a valuable resource for mainstream immunologists, comparative immunologists, geneticists, ecologists, evolutionary biologists, and investigators engaged in shark research. The book also aims to illustrate the magnificence of these animals as model systems and underscores the importance of their study to further understand their complex, and often enigmatic, biology.

The complement system is a group of proteins which plays a major role in the processing and removal of microorganisms and tissue breakdown products from the circulation and extracellular spaces. The system is activated by a wide range of targets, and activation leads to the production of opsonins, chemotaxis of granulocytes, cell lysis and other biological activities. Inappropriate overactivation of the system contributes to inflammatory tissue damage in the host, while inadequate activation leads to accumulation of immune complexes and other debris in the circulation,, and susceptibility to infection. The biology and biochemistry of the system is now adequately understood, and attempts can be made to manipulate the activation and activities of the system for potential therapeutic purposes.The reviews in this volume summarise what is known of the ways in which the complement system can be activated, by interaction with antibodies, microorganisms, cell debris, and complex carbohydrates and how the activities and activation of the system have been modified, accidentally or by design, "in vitro" or "in vivo" by drugs, venoms, particulate carbohydrates, specific antibodies, synthetic peptides and other reagents.

The understanding, at the molecular level, of the interactions between innate and adaptive arms of the immune system is currently a hot topic, particularly to those interested in immunology - especially susceptibility to infectious diseases. This book provides a survey of topics, in the area of innate and adaptive immunity, which have been researched within the MRC Immunochemistry Unit, at Oxford University, over a period of forty years. The topics include: "antibody structure - for which the first Director of the Immunochemistry Unit, Professor RR Porter, was awarded a Nobel prize in 1972 "the characterization of membrane proteins on lymphoid cells - leading to the concept of these molecules belonging to an immunoglobulin super family "the proteins of the human serum complement system - one of the body's major defences against microbial infection "the human cell -surface integrins and the hyaluronan- binding proteins, which are involved in regulation of inflammation at cell surfaces and within the extracellular matrix "the family of collectin molecules - containing distinct globular carbohydrate -binding domains linked to collagen-like regions - which play important roles in innate immunity in the lungs and bloodstream by immediate recognition and clearance of microbial pathogens Each chapter in the book gives a brief historical background to a topic and then provides a survey of recent advances in the field and are written by internationally recognised renowned experts. The theme running through the chapters is that of protein structure-function relationships - including, amongst others, descriptions of quaternary structures of large oligomeric proteins, of Factor H and C1q binding to specific ligands, and of the chemistry of the mechanism of catalysis of covalent binding of activated C3 and C4 proteins to nucleophilic groups on microbial surfaces. In several chapters excellent descriptions are given with respect to how the immune system can be recruited to combat microbial infection - via proteins of both the innate and adaptive immune systems. The book also includes notable chapters which are excellent examples of the importance of how the isolation, characterisation, protein engineering and crystallisation has resulted in a full understanding of complex protein-protein interactions involved in the recognition and triggering events of important sections of the immune system: -Structure and Function of the C1 Complex - GÚrard J. Arlaud -Chemical Engineering of Therapeutic Antibodies - George T Stevenson -Leukocyte surface proteins - purification and characterisation - A. Neil Barclay -Cell Surface Integrins - Suet-Mien Tan and S.K. Alex Law This book is aimed primarily at established senior research scientists, postdoctoral research scientists and PhD students who have an interest in proteins of the immune system. However, the wide range of immunity system topics, while staying broadly within innate/adaptive immunity will also appeal to a wider audience.

The topic of this book, Collectins, is a family of proteins whose major function is in innate immunity, where Collectins act as pattern recognition receptors (PRRs). In general they recognize targets such as microbial surfaces and apoptotic cells, and once bound to a target, Collectins promote the clearance of microorganisms and damaged host tissue. New cell-surface proteins and glycoproteins, which act as Collectin receptors, are currently being identified. Some Collectins, particularly MBL, activate the complement system, which enhances the ability of antibodies to fight pathogens, via three MBL-associated proteases, the MASPs. Additionally, recent research has begun to show wider-ranging activities of Collectins, such as: ·         Their role in metabolism, and therefore their involvement in lifestyle diseases such as obesity and cardiovascular disease.·        Their ability to modulate the adaptive immune response, as well as to recognize and trigger apoptosis of cancer cells, which makes them effective in the annihilation of cancer cells with multiple mutations.·         The regulation of their expression by gonadal steroid hormones implicates them with critical roles in both male and female fertility.·         Altered levels of Collectins have been associated with various autoimmune diseases.This book brings together current knowledge of the structure, functions and biological activities of Collectins, to describe their integral role in human health.

This book explores the potential of multi-functional carbon nanotubes for biomedical applications. It combines contributions from chemistry, physics, biology, engineering, and medicine. The complete overview of the state-of-the-art addresses different synthesis and biofunctionalisation routes and shows the structural and magnetic properties of nanotubes relevant to biomedical applications. Particular emphasis is put on the interaction of carbon nanotubes with biological environments, i.e. toxicity, biocompatibility, cellular uptake, intracellular distribution, interaction with the immune system and environmental impact. The insertion of NMR-active substances allows diagnostic usage as markers and sensors, e.g. for imaging and contactless local temperature sensing. The potential of nanotubes for therapeutic applications is highlighted by studies on chemotherapeutic drug filling and release, targeting and magnetic hyperthermia studies for anti-cancer treatment at the cellular level.
