Nanoparticles and the Immune System provides a reference text for toxicologists, materials scientists and regulators and covers the key issues of interaction of nanomaterials with the immune system. The book discusses several issues that toxicologists and regulators need to know: identification of endpoints that are relevant for assessing hazard, evaluating impact on immunologically frail populations, and how to evaluate chronic/cumulative effects. In addition, the book addresses the possibility of turning the immunomodulating properties of certain nanomaterials to our advantage for amplifying immune responses in certain diseases or preventive strategies (e.g. vaccination). Identifies endpoints relevant for assessing hazardous situations, evaluating the impact on immunologically frail populations and how to gauge chronic/cumulative effects Raises the awareness of the importance of knowing the effects of the new nanomaterials on our immune system

The immune system has the double role of maintaining tissue integrity and homeostasis and of protecting the organism from possible dangers, from invading pathogens to environmentally-borne dangerous chemicals. New chemicals recognisable by the immune system are engineered nanomaterials/ nanoparticles, new agents in our environment that are becoming common due to their presence in many products, from constructions and building material (e.g., solar cells, pigments and paints, tilesand masonry materials) to daily products (e.g., food packaging, cosmetics, and cigarettes). Human beings can be accidentally exposed to engineered nanomaterials when these are released from products containing them or during production in workplaces. Furthermore, intentional exposure occurs in medicine, as engineered nanoparticles are used as tools for improving delivery of drugs and vaccines, vaccine adjuvants and contrast agents in therapeutic, preventive and diagnostic strategies. Nanoparticles that come in contact with the immune system after unintentional exposure need to be eliminated from the organism as they represent a potential threat. In this case, however, due to their peculiar characteristics of size, shape, surface charge and persistence, nanoparticles may elicit undesirable reactions and have detrimental effects on the immune system, such as cytotoxicity, inflammation, anaphylaxis, immunosuppression. Conversely, nanomedicines need to escape immune recognition/elimination and must persist in the organism long enough for reaching their target and exerting their beneficial effects. Immune cells and molecules at the body surface (airway and digestive mucosae, skin) are the first that come in contact with nanomaterials upon accidental exposure, while immune effectors in blood are those that more easily come in contact with nanomedical products. Thus, evaluating the interaction of the immune system with nanoparticles/nanomaterials is a topic of key importance both in nanotoxicology and in nanomedicine. Immuno-nanosafety studies consider both accidental exposure to nanoparticles, which may occur by skin contact, ingestion or inhalation (at doses and with a frequency that are not known), and medical exposure, which takes place with a defined administration schedule (route, dose, frequency). Many studies focus on the interaction between the immune system and nanoparticles that, for medical purposes, have been specifically modified to stimulate immunity or to avoid immune recognition, as in the case of vaccine carriers/adjuvants or drug delivery systems, respectively. The aims of this Research Topic is to provide an overview of recent strategies: 1.for assessing the immunosafety of engineered nanomaterials/nanoparticles, in particular in terms of activation of inflammatory responses, such as complement activation and allergic reactions, based on the nanomaterial intrinsic characteristics and on the possible carry-over of bioactive contaminants such as LPS. Production of new nanoparticles taking into account their effects on immune responses, in order to avoid undesirable effects on one hand, and to design particles with desirable effects for medical applications on the other hand; 2.for designing more effective nanomedicines by either avoiding or exploiting their interaction with the immune systems, with particular focus on cancer diagnosis and therapy, and vaccination. This collection of articles gives a comprehensive view of the state-of-the-art of the interaction of nanoparticles with the immune system from the two perspectives of safety and medical use, and aims at providing immunologists with the relevant knowledge for designing improved strategies for immunologically safe nanomaterial applications.

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.

A huge effort is put into the science of nanoparticles and their production. In many cases it is unavoidable that nanoparticles are released into the environment, either during the production processes or during the use of a product made from these particles. It is also realized that combustion processes like traffic and power plants release nanoparticles into the atmosphere. However it is not known how nanoparticles interact with the human body, especially upon inhalation. At the same time research activities are devoted to understand how nano-sized medicine particles can be used to administer medicines via inhalation. In any case it is absolutely necessary to know how the nanoparticles interfere with the inhalation system, how they deposit and affect on the human system. Three main themes are discussed: Nanoparticle sources and production Nanoparticle inhalation and deposition Toxicological and medical consequences of nanoparticles Each theme is covered comprehensively, starting at nano-quantum effects up to technical and medical applications such as measuring equipment and inhalation instrumentation. This book brings together all sub-disciplines in the field related to aerosol nanoparticles. Each chapter is written by a world expert, giving the state of the art information and challenging open questions. The last chapter summarizes in an interdisciplinary way what is already known and what still is ahead of us.

This book provides a comprehensive overview of how use of micro- and nanotechnology (MNT) has allowed major new advance in vaccine development research, and the challenges that immunologists face in making further progress. MNT allows the creation of particles that exploit the inherent ability of the human immune system to recognize small particles such as viruses and toxins. In combination with minimal protective epitope design, this permits the creation of immunogenic particles that stimulate a response against the targeted pathogen. The finely tuned response of the human immune system to small particles makes it unsurprising that many of the lead adjuvants and vaccine delivery systems currently under investigation are based on nanoparticles. Provides a comprehensive and unparalleled overview of the role of micro- and nanotechnology in vaccine development Allows researchers to quickly familiarize themselves with the broad spectrum of vaccines and how micro- and nanotechnologies are applied to their development Includes a combination of overview chapters setting out general principles, and focused content dealing with specific vaccines, making it useful to readers from a variety of disciplines
