In view of rapidly growing research in the deregulation of proteases and their impact in human health and diseases, this book will highlight existing and emerging research in this exciting area. In-depth critical state-of-the-art reviews will be written by established investigators on proteases dysfunctions associated with pathogenesis of different diseases that are known to occur due to deregulation of proteolytic systems. Multidisciplinary approaches demonstrating biochemical and signal transduction mechanisms associated with deregulation of proteases leading to manifestation of the diseases will be discussed. The book highlights the roles of both intracellular and extracellular proteases in health and disease.
