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.

Target pattern recognition in innate immunity is responsible for the immediate, usually protective, responses shown against invading microorganisms, and it is the principal feature of self and non-self recognition by virtue of the recognition of structures on the microbial pathogens, which are not found on host cells. This is an area that has been very actively researched, over approximately the past 12 years, and therefore this volume provides a timely comprehensive, and up to date, summary of the types and range of cell surface, intracellular, and secreted, host proteins involved in the recognition of microbial products, and of the protective mechanisms triggered as a result of the recognition events. The Toll-like receptors, first described in Drosophila and now well-characterised on human cells, provide an excellent demonstration of the wide range of different microbial products recognised by this family of receptors and of the signalling pathways which are triggered thus leading to induction of inflammatory cytokines and the activation of genes producing antimicrobial products. In addition, several cell surface proteins involved in target pattern recognition have been described on the surfaces of macrophages (macrophage mannose receptor and macrophage scavenger receptors), and on dendritic cells (DEC205), and to be involved with the uptake and clearance of whole microorganisms and polyanioic ligands. Pattern recognition is also utilised by intracellular receptors, with NOD-like receptors in the cytosol recognizing microbial molecules and activating the production of inflammatory cytokines or pathways that induce the production of inflammatory molecules. Secreted proteins, such as the pentraxins, which includes the acute phase reacting, C-reactive protein (CRP) and serum amyloid protein (SAP), and the collectins (mannan binding lectin, lung surfactant protein A and D) and ficolins can also readily recruit killing and clearance systems. Indeed, the serum complement system, which is one of the major defence systems in the bloodstream, is efficiently activated by CR P on its binding to the phosphocholine groups of microbial phospholipids—and the subsequent interaction of the bound CR P with C1q—to give classical pathway activation, or MBL, or ficolin, binding to arrays of mannose or N-acetyl-glucosamine residues, respectively, on the surfaces of microorganisms—to give lectin pathway activation. Also, in addition to the activation and clearance events associated with complement activation by some of the secreted pattern recognition receptors, it is accepted that all these pattern recognition receptors can generally accelerate the uptake and clearance of microbes via phagocytic cells. In view of the growing interest in the cross-talk between innate and adaptive immunity, a thorough understanding of the initial recognition and triggering events, mediated via innate immune receptors, as addressed in this volume, is clearly very useful in helping to also fully understand the mechanisms of activation and control of the adaptive immune system—and to allow a full assessment of the relative roles played by innate immunity and adaptive immunity against a particular infection in higher organisms.

The recent explosion of information in innate immune pathways for recognition, effect or responses, and genetic regulation has given impetus to investigations into analogous pathways in the human immune response, which in turn has produced attendant insights into both normal physiology and immunopathology. This volume presents a compendium of methods and protocols for the investigation of human innate immunity with application to the study of normal immune function, immunosenescence, autoimmunity and infectious diseases. Among the topics covered are quantitative flow cytometry for Toll-like receptor expression and function; multidimensional single cell mass cytometry (CyTOF) in complex immune interactions and tumor immunity; imaging techniques such as Imagestream high resolution microscopy coupled to flow cytometry, immune cell infiltration of organotypic, biomimetic organs; high-throughput single cell secretion profiling; multiplexed transcriptomic profiling; microsatellite and microRNA methodologies, RNA interference; and the latest bioinformatics and biostatistical methodologies, including in-depth statistical modeling, genetic mapping, and systems approaches.

The innate immune system represents a critical arm of the immune response by providing immediate and robust host defense; however, human studies of its function are often limited by ethical, logistical, and technical obstacles. In Mouse Models of Innate Immunity: Methods and Protocols, experts in the field explore the design and execution of experiments used to thoroughly evaluate critical elements associated with the host innate immune response. The volume opens with methods that are essential for collecting and assessing various primary cells that are highly relevant to innate immunity, and it continues with in vivo protocols commonly used to evaluate the innate immune response in the mouse, including mouse models of respiratory infection, gastrointestinal inflammation, fungal and parasitic diseases, sepsis, and HIV-1 infection. Written in the highly 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 laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and easy to use, Mouse Models of Innate Immunity: Methods and Protocols will serve the research community by providing expert advice and protocols that allow both experienced and novice investigators to successfully plan, implement, and assess disease processes associated with the innate immune response.

This volume presents a collection of reviews derived from work presented at the Aegean Conference: “4th Crossroads between innate and adaptive immunity”. This meeting was the fourth in a series, and assembled a team of scientists working on mechanisms by which the innate immune system of the host senses pathogens, the cellular and signaling networks that orchestrate the innate response and antigen presentation and adaptive immunity. The importance of the crosstalk between innate immunity and the adaptive immune response has only recently started to be appreciated. Although it is well recognized that dendritic cells, NK cells, NK-T cells and T cells are all critical for the host response to pathogens, the respective fields that study the biology of these immune cells tend to exist in parallel worlds with minimum exchange of information and ideas. This fragmentation hinders the integration of these fields towards a unified theory of host response. The Aegean Conference “Crossroads between Innate and Adaptive Immunity” brought together leading international scientists and experts to address critical areas of Innate and Adaptive immunity something necessary for the development of more efficient scientific exchange and crosspollination between these fields. This conference attracted scientists from all over the world to discuss their latest findings on the various aspects of Innate and Adaptive immunity. The conference had limited participation and a scientific and social program that maximized scientific interchange through lecture presentations, poster sessions and informal discussions.

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.
