This book, the proceedings of Falk Symposium 133 on Mechanisms of Intestinal Inflammation: Implications for Therapeutic Intervention in IBD', held in Berlin, Germany, on 10-11 June 2003, summarizes present knowledge in the area of unspecific and specific immune reactions in the gut, recording the gaps in our knowledge and, in particular, presenting the possibilities of targeted intervention. The link to inflammatory bowel diseases - Crohn's disease and ulcerative colitis - is always in focus. Chapters by an international panel of basic scientists, clinical researchers and clinicians also record the problems which can originate through today's possible modulation of the immune reaction, setting the basis for review of clinical problems. This book is valuable readings for all scientists and physicians, who, from different perspectives, have an interest in research on IBD and in the clinical management of these diseases.
