Book Description
Of the many special roles played by proteolytic enzymes in immune reactions, this book addresses different aspects of membrane peptidases, signal transduction via ligation of membrane peptidases (especially of dipeptidyl peptidase IV/CD26 and aminopeptidase N/CD13), and regulation of membrane peptidases in vivo and in vitro. A number of newly discovered peptidases (including cathepsin F, W and X, carboxypeptidase X, attractin) are described, with special emphasis given to the role of peptidases in immune and defense reactions and in the pathogenesis of inflammatory and other diseases, including rheumatoid arthritis, pancreatitis, multiple sclerosis, Alzheimer's disease and tumours of various origins. The focus on the involvement of a selection of proteolytic enzymes in immune reactions and diseases is a unique feature of this multifaceted work , which combines biochemical, immunological and clinical research reports with literary reviews of the field.

Book Description
Cells bristle with a battery of surface enzymes, of which the peptidases form the largest and best studied group. These ectopeptidases play crucial roles in many diverse biological functions, including the termination of peptide signals in the nervous system and at peripheral sites. Some of their key physiological roles, such as those of angiotensin- and endothelin-converting enzymes in generating vasoconstrictive agents and endopeptidase-24.11 in activating natriuretic peptides, enkephalins and tachykinins, have made them prime targets for the pharmaceutical industry. Interest among immunologists and haematologists was aroused when several were shown to be identical to cell-surface markers (CD antigens) on human leukocytes. Virologists have been excited to find that some double as receptors for certain viruses.

Book Description
Cell Surface Proteases provides a comprehensive overview of these important enzymes that catalyze the hydrolysis of a protein as it degrades to a simpler substance. In the 1990s, an explosion of new discoveries shed light on the role of cell surface proteases and extended it beyond degradation of extracellular matrix components to include its influence on growth factors, cell signaling, and other cellular events. This volume unites the scientific literature from across disciplines and teases out unified themes of interactions between cell surface proteases and interconnecting cell surface-related systems -- including integrins and other adhesion molecules. Scientists and students involved in developmental biology, cell biology and disease processes will find this an indispensable resource.* Provides an overview of the entire field of cell surface proteases in a single volume* Presents major issues and astonishing discoveries at the forefront of modern developmental biology and developmental medicine * A thematic volume in the longest-running forum for contemporary issues in developmental biology with over 30 years of coverage

Book Description
Proceedings of the International Conference on Dipeptidyl Aminopeptidases, held September 26-28, 2002, in Berlin, Germany. Dipeptidyl Aminopeptidases exert a potent modulatory role at an interface between immune mechanisms, metabolic responses and neuroendocrine pathways. Experimental models and clinical studies addressing the role of these enzymes and the effect of specific inhibitors pave the way to novel therapeutic concepts in immunology, rheumatology, oncology, reproductive medicine and diabetes. Leading experts in this field have contributed to this book which presents a state-of-the-art view on these enzymes, at a time when our understanding of their function is growing ever more rapidly and therapeutic options become imminent. The sections of the book focus on various topics: - Structure and function of dipeptidyl aminopeptidases, - DPP IV-like proteins, - Immune mechanisms and immune disorders, - Cancer and angiogenesis, - Diabetes and metabolism, - Therapeutic implications.

Book Description
The secretions of the exocrine pancreas provide for digestion of a meal into components that are then available for processing and absorption by the intestinal epithelium. Without the exocrine pancreas, malabsorption and malnutrition result. This chapter describes the cellular participants responsible for the secretion of digestive enzymes and fluid that in combination provide a pancreatic secretion that accomplishes the digestive functions of the gland. Key cellular participants, the acinar cell and the duct cell, are responsible for digestive enzyme and fluid secretion, respectively, of the exocrine pancreas. This chapter describes the neurohumoral pathways that mediate the pancreatic response to a meal as well as details of the cellular mechanisms that are necessary for the organ responses, including protein synthesis and transport and ion transports, and the regulation of these responses by intracellular signaling systems. Examples of pancreatic diseases resulting from dysfunction in cellular mechanisms provide emphasis of the importance of the normal physiologic mechanisms.

Book Description
The idea to compile recent results on the ectoenzymes aminopeptidase N/CD13 and dipeptidylpeptidase IV/CD26 arose from the great interest given by readers world-wide to the two proceedings volumes edited by us in 1997 and 2000 (Ansorge and Langner, 1997; Langner and Ansorge, 2000). These volumes contained the presentations at two symposia held in Magdeburg (Germany) in 1996 and 1999 under the title "Cellular peptidases in immune functions and diseases", which was also the name of the Sonderforschungsbereich in Magdeburg, sponsored by the Deutsche Forschungsgemeinschaft between 1995 and 2001. Our groups in Magdeburg and Halle during the last two decades have provided results on these two enzymes in cells of the hematopoietic system that justify a review in an edited monograph like the present one (see the reviews by Kahne et at. , 1999; Lendeckel et at. ,1999; Riemann et at. , 1999). There are, however, many other groups in Europe, US and Japan which made important contributions to this field and particularly in topics improving the understanding of physiological and pathophysiological roles ofAPN/CD13 and DPIV/CD26. Therefore we decided to invite some of them to contribute reviews of their results to this book. Having worked for about 40 years in the field of proteolysis, for both of us to see the development of activities and knowledge from protein chemistry and enzymology to physiology and pathophysiology and even to therapy is very stimulating and fascinating. Of course, this development also reflects the dramatic improvement and refinement of methods.

Book Description
Immunity and Inflammation in Health and Disease: Emerging Roles of Nutraceuticals and Functional Foods in Immune Support provides a comprehensive description of the various pathways by which the vertebrate immune system works, the signals that trigger immune response and how fnew and novel nutraceuticals and functional foods, can be used to contain inflammation and also to boost immunity and immune health. Inflammation is a tool to fight pathogens and the vertebrate immune system has a very complex network of cells to achieve this. However inflammation that goes awry is also the leding cause of several diseases ranging from cardiovascular diseases to diabetes. This book covers the entire gamut from the various cellular players in the inflammation-immune response to its ramifications in terms of protection against pathogens as well as in onset of metabolic, aging and auto-immune related diseases. Finally, the balancing role of dietary nutrients between host defence and immune support is also showcased. The first three scetions explain the various components of the immune system and their modes of activation. The fourth section deals with the ramifications of a robust and execessive inflammatory response. The fifth section is focused on the association between nutrition and immunity and how deficiencies in certain nutrients may affect immunocompetence. The sixth section chapters represent a vision of paradigm shifts within the field and discusses possible future directions. This bool will be a valuable reference for researchers studying immune health either in academia, or in the nutraceutical or functional food industries. Product developers in nutraceutical, supplement, functional food, and health food companies will also appreciate the information presented here. - Conceptualizes the key features in natural products which can boost immune function and immune health - Explains the intricate mechanistic aspects and balance behind immune health - Presents the pathophysiology of several diseases associated with immune system disruption
