Biomaterials have existed for millennia as mechanical replacement structures following disease or injury. Biomaterial design has changed markedly from structural support with an "inert immune profile as the primary objective to designs that elicit an integrative local tissue response and a pro-repair immune cell phenotype. Immunomodulatory Biomaterials: Regulating the Immune Response with Biomaterials to Affect Clinical Outcome offers a single, comprehensive reference on biomaterials for modulation of the host response, for materials scientists, tissue engineers and those working in regenerative medicine. This book details methods, materials and strategies designed to regulate the host immune response following surgical implantation and thus facilitate specific local cell infiltration and tissue deposition. There has been a dramatic transformation in our understanding of the role of the immune system, both innate and adaptive; these changes include recognition of the plasticity of immune cells, especially macrophages, cross-talk between the immune system and stem cells, and the necessity for in situ transition between inflammatory and regulatory immune cell phenotypes. The exploitation of these findings and the design and manufacture of new biomaterials is occurring at an astounding pace. There is currently no book directed at the interdisciplinary principles guiding the design, manufacture, testing, and clinical translation of biomaterials that proactively regulate the host tissue immune response. The challenge for academia, industry, and regulatory agencies to encourage innovation while assuring safety and maximizing efficacy has never been greater. Given the highly interdisciplinary requirements for the design, manufacture and use of immunomodulatory biomaterials, this book will prove a useful single resource across disciplines. - Holistically covers the design, manufacture, testing, and clinical translation of biomaterials that proactively regulate the host tissue immune response - Provides a single reference for understanding and utilizing the host response in biomaterials design - An international collaboration of leading researchers in the field offering a novel insight into this fast-growing area

The prevention and control of infectious diseases represents, even today, an important public health problem for responsible national and international authorities. Newly emerging p.athogens such as human immunodeficiency virus (HIV) , legionella, and bovine spongiform encephalopathy (BSE) have captured current public awareness. Despite significant success against smallpox, polio myelitis, mumps, and measles, the vast majority of infectious diseases are yet to be satisfactorily controlled. Limited efficacy of some vaccines, e. g., against influenza viruses, or their nonavailability have hampered an effective control of many infections. A meaningful reduction of the health risks posed by microbial pathogens is of crucial importance. Increased efforts need to be exerted in areas of active and passive immunization as well as in stimulation of enhanced nonspecific resistance .. Progress in the field of infectious diseases can be accelerated when a generation of new improved vaccines are developed. These vaccines should be capable of activat ing the cellular and the humoral immune responses as well as inducing persistent immunological memory. Development of novel regimens for enhancing natural resistance against infections is also progressively gaining in importance. The urgency increases as chemotherapy against viral and other infections further continues to be plagued by a carousel of a limited number of licensed drugs, problems of side effects, and development of drug resistance. It is becoming expedient that future strategies embrace a policy directed towards triggering mechanisms capable of inducing specific and nonspecific host defences.

Molecular recognition undoubtedly governs any aspect of cellular interaction. To understand tumor cell growth regulation and spread, analysisof protein carbohydrate interactions can contribute to lead to the establishment of rational methods for diagnosis and therapy. Chemically and biochemically optimized preparation of adequate tools, their application for localization of receptor (tissue lectin) and ligand (cellular glycoconjugate) pairs in tumor cells and tumor sections and the usefulness of a lectin from a plant extract as potent immunomodulator indicate the prospect for a place of such techniques in pathology and oncology.
