C1q is the target recognition protein of the classical complement pathway and a major connecting link between innate and acquired immunity. As a charge pattern recognition molecule of innate immunity, C1q can engage a broad range of ligands derived from self, non-self and altered self via its heterotrimeric globular (gC1q) domain and thus trigger the classical complement pathway. The trimeric gC1q signature domain has been identified in a variety of non-complement proteins that can be grouped together as a C1q family. C1q circulates in serum as part of the C1 complex, in association with a catalytic tetrameric assembly of two homologous yet distinct serine proteases, C1r and C1s. Binding of C1q to appropriate targets leads to sequential activation of C1r and C1s, the latter being able to cleave complement components C4 and C2 thereby triggering the complement cascade. Activation of the classical pathway plays an important role in innate immune protection against pathogens and damaged elements from self. However, its involvement has been shown in various pathologies including ischemia-reperfusion injury and hereditary angioedema. Unexpected roles for the classical pathway have also been discovered recently, linked to both physiological and pathological aspects of development, including brain and cancer cells. These new perspectives should arouse renewed interest in a search for specific inhibitors of the classical pathway. In addition, C1q has recently been shown to have a number of functions that are independent of the activation of the classical pathway. This research topic is aimed at providing a state-of-the-art overview of the classical pathway, including, but not restricted to emerging functions of C1q and of the C1 complex, as well as pathological consequences of C1 activation or of the presence of anti-C1q autoantibodies . Contributions are included in the areas such as structural basis of C1q ligand recognition, C1q family proteins, inhibitors of the classical pathway identified in pathogens and improved derived inhibitors, structural determinants of the substrate specificities of C1r and C1s, elucidation of the architecture of C1, structural and functional homology of C1 with the initiating complexes of the lectin complement pathway, and novel involvement of C1q in processes such as ageing, cancer, synaptic pruning, and pregnancy.

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.

This book presents current understanding of the importance of modern immunology in the etiopathogenesis of human diseases and explores how this understanding is impacting on diagnosis, prognosis, treatment, and prophylaxis. As the core of modern immunology, the “danger/injury model” is introduced and addressed throughout the book. Volume I of the book describes the network of damage-associated molecular pattern molecules (DAMPs) and examines the central role of DAMPs in cellular stress responses and associated regulated cell death, the promotion and resolution of inflammation, the activation of innate lymphoid cells and unconventional T cells, the stimulation of adaptive immunity, and tissue repair. The significance of DAMPs in a wide range of human diseases will then be explored in Volume II of the book, with discussion of the implications of injury-induced innate immunity for present and future treatments. This book is written for professionals from all medical and paramedical disciplines who are interested in the introduction of innovative data from immunity and inflammation research into clinical practice. The readership will include practitioners and clinicians such as hematologists, rheumatologists, traumatologists, oncologists, intensive care anesthetists, endocrinologists such as diabetologists, psychiatrists, neurologists, pharmacists, and transplantologists.

Janis Kuby’s groundbreaking introduction to immunology was the first textbook for the course actually written to be a textbook. Like no other text, it combined an experimental emphasis with extensive pedagogical features to help students grasp basic concepts. Now in a thoroughly updated new edition, Kuby Immunology remains the only undergraduate introduction to immunology written by teachers of the course. In the Kuby tradition, authors Jenni Punt, Sharon Stranford, Patricia Jones, and Judy Owen present the most current topics in an experimental context, conveying the excitement of scientific discovery, and highlight important advances, but do so with the focus on the big picture of the study of immune response, enhanced by unsurpassed pedagogical support for the first-time learner. Punt, Stranford, Jones, and Owen bring an enormous range of teaching and research experiences to the text, as well as a dedication to continue the experiment-based, pedagogical-driven approach of Janis Kuby. For this edition, they have worked chapter by chapter to streamline the coverage, to address topics that students have the most trouble grasping, and to continually remind students where the topic at hand fits in the study of immunology as a whole.
