Immunomodulatory Biomaterials

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 interactions of the biomaterials with the host immune system is crucial for their functionality. This book aims to provide the reader with a better understanding of the role of the immune system in biomaterial applications. For this end, the book has dedicated chapters for i) explaining immune cells taking part in immune response to biomaterials/immune systems interface; ii) the effect of biomaterial shape, form and physicochemical properties on the response of immune system; iii) biofilm formation on implanted materials as a failure of immune system/biomaterial interactions; iv) tissue-specific effects of immune response and its consequences for tissue engineering and regenerative medicine; v) immune reaction in a clinical context (periodontology). In the field of biomaterials there are significant advances in using immunomodulation techniques to improve the success rates of implantable materials. For better understanding of such techniques it is required to have a full grasp of the biomaterial–immune system interactions. This would greatly enhance the understanding of why the human body reacts to implants in a certain way and how to improve the clinical outcomes by developing immune-instructive biomaterials. Provides keen insight into biomaterial–immune cell interactions Presents an explanation of state-of-the-art methodologies in immunomodulation Offers a concise and simple-to-understand treatment of biomaterial–immune cell interactions for materials scientists in a biology heavy topic Explores a comprehensive overview of biomaterial related complications Provides extensive references at the end of each chapter to enhance study for this very hot research area

This book presents the recent developments in immunomodulatory biomaterials for cell-based therapies in various diseases, including diabetes, cancer, cardiovascular disease, and bone regeneration. The authors first cover the fundamentals of conventional immunology and immunomodulation, before focusing on the history, advantages, and challenges of cell therapies. Biological cell therapy has gained immense attention for various diseases due to unique advantages it has over chemical drugs regarding cost, ease of production, toxicity, and therapeutic efficacy. However, these cell-based therapies need an inert delivery system that can locally deliver cells and minimally elicit foreign body response. The book discusses the foreign body response to the immunomodulatory biomaterials as well as the current and future strategies for potential mitigation of considerable immune responses toward immunomodulatory biomaterials and devices.

Immunomodulatory Effects of Nanomaterials: Assessment and Analysis provides an overview of the modulatory impact of nanomaterials on the immune system, as well as evaluative and analytical methods for assessing effects. Sections cover a range of common nanomaterials for biomedical use and how different properties can elicit varied responses from the immune system. The immunomodulatory effects of these materials are then discussed, with coverage on adverse and/or toxic effects on the immune system, as well as desired modulatory effects to improve efficacy of applied therapeutics. Readers will also learn about the best evaluation methods for immunomodulatory effects of nanomaterials and associated risks. This book is a useful reference for academics and researchers with an interest in immunology, but it is also idea for those working in the fields of materials science, biomedical engineering, pharmaceutical science, immunology and toxicology. Details a range of common nanomaterials and how their specific properties and characteristics interact with the immune system Discusses the immunomodulatory effects of nanomaterials, from unintentional and potentially harmful, to intentional and desired effects on the immune system Explores methods for evaluation of immunomodulatory effects of nanomaterials, as well as precautions and risks for data analysis and interpretation

The generation of tridimensional tissues, assembled from scaffolding materials populated with biologically functional cells, is the great challenge and hope of tissue bioengineering and regenerative medicine. The generation of biomaterials capable of harnessing the immune system has been particularly successful. This book provides a comprehensive view of how immune cells can be manipulated to suppresses inflammation, deliver vaccines, fight cancer cells, promote tissue regeneration or inhibit blood clotting and bacterial infections by functionally engineered biomaterials. However, long-lived polymers, such as those employed in orthopedic surgery or vascular stents, can often induce an immune reaction to their basic components. As a result, this book is also an important step towards coming to understand how to manipulate biomaterials to optimize their beneficial effects and downplay detrimental immune responses.
