Book Description
In recent years, powered by evolving technologies and experimental design, studies have better illuminated the regulating role of proteolytic enzymes across human development and pathologies. Proteolytic Signaling in Health and Disease provides an in-depth discussion of fundamental physiological and developmental processes regulated by proteases, from protein turnover and autophagy to antigen processing and presentation and major histocompatibility complex (MHC) molecules. Moving on from basic biology, international chapter authors examine a range of pathological conditions associated with proteolysis, including inflammation, wound healing, and cancer. Later chapters discuss the newly discovered network of connected events among proteases (and their inhibitors), the so-called ‘protease web’, and how best to study it. This book also empowers new research with up-to-date analytical methods and step-by-step protocols for studying proteolytic signaling events. Examines biological events triggered by proteolytic enzyme activity across human development and pathologies Discusses the role of proteolytic signaling in inflammation, wound healing, and cancer, among other disease types Features methods and protocols supporting further study of proteolytic signaling events Includes chapter contributions from international leaders in the field

Book Description
This book bridges the gap between fundamental research and biomedical and pharmacological applications on proteases. It represents a comprehensive overview of the multifaceted field of proteases in cellular environment and highlights the recently elucidated functions of complex proteolytic systems in different diseases. Several established investigators have elucidated the crucial role of proteases in biological processes, including how proteolytic function and regulation can be combined to develop new strategies of therapeutic interventions. Proteases form one of the largest and most diverse families of enzymes known. It is now clear that proteases are involved in every aspect of life functions of an organism. Under physiological conditions, proteases are regulated by their endogenous inhibitors; however, when the activity of proteases is not regulated appropriately, disease processes can result in. So, there is absolute need for a stringent control of proteolytic activities in cells and tissues. Dysregulation of proteases may cause derangement of cellular signalling network resulting in different pathophysiological conditions such as vascular remodelling, atherosclerotic plaque progression, ulcer and rheumatoid arthritis, Alzheimer disease, cancer metastasis, tumor progression and inflammation. Additionally, many infective microorganisms require proteases for replication or use proteases as virulence factors, which have facilitated the development of protease-targeted therapies for a variety of parasitic diseases.

Book Description
We are pleased to present to our readers the Proceedings of the International Symposium "Proteases: Potential Role in Health and Disease" which was held in WUrzburg (FRG) during October 17-20, 1982. The topics discussed included those dealing with the physi ology and pathophysiology of proteases and their inhibitors, the interactions of proteases and hormones, the kallikrein-kinin system, complement and the coagulation system, the function of proteases in the kidney and the intestinal tract as well as the role of proteases in lung diseases, pancreatitis, arthritis and hypercatabolic states (multiple trauma, septicemia, acute renal failure). The papers presented answered many questions, but raised many more concerning the significance of proteases and their inhibitors in clinical medicine. It was unfortunately impossible in this volume to in clude the extended, lively and extremely stimulating discussions which were enjoyed by the participants during the conference. The meeting has provided a unique framework for close inter action between scientists from various disciplines, including bio chemistry, physiology, surgery, anaesthesiology, endocrinology, hematology, pulmonology and nephrology. We would like to express our thanks and appreciation for all those who have stimulated, encouraged and supported us to hold this symposium in WUrzburg. This endeavor could not have been possible without the generous financial support of the Paul-Martini Foundation (Mainz), Bayer AG (Leverkusen), Beiersdorf AG (Hamburg).

Book Description
Proteolysis is an irreversible posttranslational modification affecting each and every protein from its biosynthesis to its degradation. Limited proteolysis regulates targeting and activity throughout the lifetime of proteins. Balancing proteolysis is therefore crucial for physiological homeostasis. Control mechanisms include proteolytic maturation of zymogens resulting in active proteases and the shut down of proteolysis by counteracting endogenous protease inhibitors. Beyond the protein level, proteolytic enzymes are involved in key decisions during development that determine life and death – from single cells to adult individuals. In particular, we are becoming aware of the subtle role that proteases play in signaling events within proteolysis networks, in which the enzymes act synergistically and form alliances in a web-like fashion. Proteases come in different flavors. At least five families of mechanistically distinct enzymes and even more inhibitor families are known to date, many family members are still to be studied in detail. We have learned a lot about the diversity of the about 600 proteases in the human genome and begin to understand their physiological roles in the degradome. However, there are still many open questions regarding their actions in pathophysiology. It is in this area where the development of small molecule inhibitors as therapeutic agents is extremely promising. Approaching proteolysis as the most important, irreversible post-translational protein modification essentially requires an integrated effort of complementary research disciplines. In fact, proteolytic enzymes seem as diverse as the scientists working with these intriguing proteins. This book reflects the efforts of many in this exciting field of research where team and network formations are essential to move ahead.

Book Description
Proteolytic enzymes are found in all life forms, where they catalyze peptide bond hydrolysis during essential biological processes. Proteases of various pathogens have also been shown to use endogenous protease inhibitors to regulate the activity of host proteolytic enzymes encountered during infection. Proteolytic Enzymes and their Inhibitors in Infectious Pathogens brings together key experts to provide a thorough discussion of proteolytic enzymes and their endogenous inhibitors found in parasites, bacteria, and viruses. The book focuses on the respective roles of the different catalytic classes of proteolytic enzymes and their protein-protease inhibitors at the host-infectious organism interface, and how this knowledge may inform drug and vaccine design. Following a foundational overview of proteases and macromolecular inhibitors of pathogenic organisms, authors discuss recent research on distinct classes of proteolytic enzymes in pathogens. Classes include aspartic proteases, cysteine proteases, metalloproteases, serine proteases, and threonine proteases with experts contributing chapters on distinct enzymes and inhibitors. New methods to identify protease substrates and inhibitors are also provided, with step-by-step protocols to advance new research and drive drug discovery. Discusses proteolytic enzymes of parasites, bacteria, and viruses arranged by peptide bond cleavage classes, for improved integration of information across the infectious organisms Includes information on the structure and interaction with proteases of macromolecular protease inhibitors, and how these structures can be engineered to provide more potent and specific protease inhibitors Provides instructions in methods and technologies to identify physiological protease substrates, their cleavage specificities, and inhibitors Features rich illustrations and diagrams of core concepts, including informative three-dimensional protein structures and molecular interactions

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.
