The inducible isoforms of the enzymes cyclooxygenase (COX 2), nitric oxide synthase (iNOS) and heme oxygenase 1 (HO-1) have generated great interest as possible therapeutic targets in inflammation. This book is the first publication to address the importance of all three enzymes and the consequences of their interactions to the inflammatory process. The book brings together overviews by leading researchers in the field of the current status of knowledge of COX, NOS and HO in inflammation. These overviews cover a series of new concepts in the mechanism of inflammation. Topics include inducible enzyme involvement in inflammatory processes including the role in vascular permeability, leukocycte migration, granuloma formation, angiogenesis, neuroinflammation and algesia. New findings from transgenic animal models are reviewed. Other chapters address the importance of these enzymes in inflammatory disease states including rheumatoid arthritis, atherosclerosis and multiple sclerosis. The possibility of selective inhibitors or inducers of COX, NOS and HO, and their use in the clinic is discussed. The subject matter of this book is of interest to rheumatologists, pathologists, pharmacologists, neuroscientists and anyone with an academic interest in the mechanisms of inflammation.

Inflammation has been described as the basis of many pathologies of human disease. When one considers the updated signs of inflammation, they would be vasodilation, cell migration, and, in the case of chronic inflam- tion, cell proliferation, often with an underlying autoimmune basis. Gen- ally, inflammation may be divided into acute, chronic, and autoimmune, - though the editors believe that most, if not all, chronic states are often the result of an autoimmune response to an endogenous antigen. Thus, a proper understanding of the inflammatory basis may provide clues to new therap- tic targets not only in classical inflammatory diseases, but atherosclerosis, cancer, and ischemic heart disease as well. The lack of advances in classical inflammatory diseases, such as rh- matoid arthritis, may in part arise from a failure to classify the disease into different forms. That different forms exist is exemplified in patients with d- fering responses to existing antiinflammatory drugs, ranging from nonresponders to very positive responders for a particular nonsteroidal an- inflammatory drug (NSAID). Though researchers have progressively unr- eled the mechanisms, the story is far from complete. It should also be noted that the inflammatory response is part of the innate immune response, or to use John Hunter's words in 1795, "inflammation is a salutary response." That may be applied in particular to the defensive response to invading micro- ganisms.
