Leukocyte adhesion molecules have been the subject of intense basic and preclinical research. Results from clinical trials obtained sofar with antibodies directed towards these surface proteins offer promise for the prevention of graft rejection and effective treatment of acute and chronic inflammatory disease. This volume presents a comprehensive review of contemporary research on the structure, function and regulation of leukocyte adhesion molecules and their ligands, from the molecular to the clinical level. The blend of basic science and clinical applications presented in Structure, Function and Regulation of Molecules Involved in Leukocyte Adhesion provides clear evidence of the biological importance of cell-cell interactions and the many potential clinical dividends afforded by understanding the molecular basis of cell adhesion. It will appeal to a broad range of readers in immunology and cell biology.
Leukocyte adhesion molecules promise to be highly effective as antigens in the antibody-directed leucocyte elimination treatment prior to grafting or in cases of acute and chronic inflammatory disease. This comprehensive review of contemporary research provides thorough discussions of the structure of these molecules, their in vitro function, and the role that they play in vivo as evidenced by results shown in inflammatory models where antibodies against these molecules are given to inhibit their function. The blend of basic science and clinical applications provides clear evidence of the biological relevance of cell-cell interactions and the many potential clinical dividends afforded by understanding the molecular basis of cell adhesion.
Inflammatory cell recruitment requires the concerted action of at least five major sets of adhesion molecules: integrins, immunoglobulin-like molecules, selectins, carbohydrate structures serving as selectin ligands, and certain ectoenzymes. This volume gives a comprehensive overview on the most relevant leukocyte and endothelial adhesion molecules. The chapters are written by leaders in the field and focus on the biology, structure, function, and regulation of adhesion molecules. Currently approved adhesion molecule-based therapies are reviewed and an outlook for future approaches is also provided. The book is of interest to clinicians and scientists from immunology, physiology, cancer research, rheumatology, allergology, infectious diseases, gastroenterology, pulmonology and cardiology.
The localized attachment of circulating leukocytes to endothelium has been recognized as the cellular hallmark of the inflammatory response. This adhesive interaction, a necessary antecedent to the emigration of leukocytes from the blood into the tissues, is mediated by vascular adhesion molecules. Leukocyte Recruitment, Endothelial Cell Adhesion Molecules and Transcriptional Control: Insights for Drug Discovery outlines some of the cellular and molecular mechanisms of inflammation with contributions from top researchers. This volume provides an overview of three of these endothelial adhesion molecules, as examples of key mediators of leukocyte recruitment. It reviews the structure and regulation of these cell surface proteins and focus on the rapidly expanding field of transcriptional regulation of these inducible proteins, and closes with a discussion of drug discovery possibilities that target the regulation of leukocyte recruitment. This book will be of interest for any researchers, in academia or industry, looking for an overview of leukocyte recruitment or novel approaches to drug discovery.
Provides an overview of the structure, transcription regulation and binding characteristics of cellular adhesion molecules and their ligands in the maintenance of function, immunological reactions and inflammatory processes with organ systems. The text examines the role of adhesion molecules in biological processes such as morphogenesis, blood coagulation, tumour metastasis, bone tissue remodelling and transplant rejection.
This book covers the structure and classification of adhesion molecules in relation to signaling pathways and gene expression. It discusses immunohistochemical localization, neutrophil migration, and junctional, functional, and inflammatory adhesion molecules in pathologies such as leukocyte decompression sickness and ischemia reperfusion injury.

The microcirculation is highly responsive to, and a vital participant in, the inflammatory response. All segments of the microvasculature (arterioles, capillaries, and venules) exhibit characteristic phenotypic changes during inflammation that appear to be directed toward enhancing the delivery of inflammatory cells to the injured/infected tissue, isolating the region from healthy tissue and the systemic circulation, and setting the stage for tissue repair and regeneration. The best characterized responses of the microcirculation to inflammation include impaired vasomotor function, reduced capillary perfusion, adhesion of leukocytes and platelets, activation of the coagulation cascade, and enhanced thrombosis, increased vascular permeability, and an increase in the rate of proliferation of blood and lymphatic vessels. A variety of cells that normally circulate in blood (leukocytes, platelets) or reside within the vessel wall (endothelial cells, pericytes) or in the perivascular space (mast cells, macrophages) are activated in response to inflammation. The activation products and chemical mediators released from these cells act through different well-characterized signaling pathways to induce the phenotypic changes in microvessel function that accompany inflammation. Drugs that target a specific microvascular response to inflammation, such as leukocyte-endothelial cell adhesion or angiogenesis, have shown promise in both the preclinical and clinical studies of inflammatory disease. Future research efforts in this area will likely identify new avenues for therapeutic intervention in inflammation.

The consequences of diseases involving the immune system such as AIDS, and chronic inflammatory diseases such as bronchial-asthma, rheumatoid arthritis and atherosclerosis, now account for a considerable economic burden to governments worldwide. In response there has been an enormous research effort investigating the basic mechanisms underlying such diseases, and a tremendous drive to identify novel therapeutic applications for their prevention and treatment. Though a plethora of immunological studies have been published in recent years, little has been written about the implications of such research for drugs development. As a consequence, this area has not gained the prominence of other fields such as molecular pharmacology or neuropharmacology, and a focul information source for the many pharmacologists interested in diseases of the immune system remains unpublished. The Handbook of Immunopharmacology series provides such a source through the commissioning of a comprehensive collection of volumes on all aspects of immunopharmacology. Editors have been sought after for each volume who are not only active in their respective areas of expertise, but who also have a distinctly pharmacological bias to their research. The series follows three main themes, each represented by volumes on individual component topics. The first covers each of the major cell types and classes of inflammatory mediators ("cells and mediators"). The second covers each of the major organ systems and the diseases involving the immune and inflammatory responses that can effect them ("systems"). The third covers different classes of drugs currently used to treat these diseases as well as those under development ("drugs"). This volume provides a comprehensive overview of the adhsion molecules, processes and concepts that govern both inflammatory and infectious diseases, and also deals in detail with the specific in vivo pathways involved. The first chapter introduces some of the molecules that mediate leukocyte adhesion and ranges from their discovery using monoclonal antibodies and a congenital adhesion deficiency, to their antagonism in preliminary clinical trials as novel therapeutics. An in-depth analysis of the structure, distribution and function of the cell surface glycoproteins that regulates lymphocyte (specific immune response), granulocyte (acute inflammatory response) and metastatic cell (malignant processes) adhesions respectively is provided by the next three chapters. Chapters 5 and 7 detail the molecular structure, intracellular pathways, specificty of carbohydrate interactions, and signalling of the molecules that regulate leukocyte-leukocyte and leukocyte-mesenchymal cell interactions. There follows an exploration into the contributions of specific molecules in inflammatory diseases in various organs from chapters 8-11. The concluding part is unique to this volume by reviewing the comparable, and in some cases same, cell surface molecules that mediate virus, bacteria and parasite interactions with host cells. The research is far from complete, but Adhesion Molecules is extremely comprehensive and will be a valuable resource for many a year to come.
