The fast development in the field of nanotechnology has led to a high variety of nanoparticles. Nanoparticles find importance in every sphere of human lives and more so in the recent years have tremendous applications in the sector of biomedical clinical medicine as diagnostic, prognostic and imaging tools. Their risk to human and animal life as well as to the environment is still unclear. Therefore, the study of the impact of nanoparticles on human and animal life is important. Volume I highlights the impact of nanoparticles on the human immune system. While discussing the basic biology of the immune system, this book highlights the downstream effect of nanoparticles on the human immune system. Research studies on the development of better and more effective nanoparticles with more precise and accurate effects and with toxic minimal side effects are discussed in the book. Both volumes are also included in a set ISBN 978-3-11-065666-4.

Drawing on indigenous and scientific knowledge of medicinal plants, Traditional Herbal Therapy for the Human Immune System presents the protective and therapeutic potential of plant-based drinks, supplements, nutraceuticals, synergy food, superfoods, and other products. Medicinal plants and their products can affect the immune system and act as immunomodulators. Medicinal plants are popularly used in folk medicine to accelerate the human immune defence and improve body reactions against infectious or exogenous injuries, as well as to suppress the abnormal immune response occurring in immune disorders. This book explains how medicinal plants can act as a source of vitamins and improve body functions such as enhanced oxygen circulation, maintained blood pressure and improved mood. It also outlines how specific properties of certain plants can help boost the immune system of humans with cancer, HIV, and COVID-19. Key features: Provides specific information on how to accelerate and or fortify the human immune system by using medicinal plants. Presents scientific understanding of herbs, shrubs, climbers and trees and their potential uses in conventional and herbal medicine systems. Discusses the specific role of herbal plants that act as antiviral and antibacterial agents and offer boosted immunity for cancer, H1N1 virus, relieving swine flu, HIV and COVID-19 patients. Part of the Exploring Medicinal Plants series, this book is useful for researchers and students, as well as policy makers and people working in industry, who have an interest in plant-derived medications.

Recent advances in the understanding of microbiota in health and diseases are presented in this special issue of Frontiers in Immunology and Frontiers in Microbiology as well as their impact on the immune system that can lead to the development of pathologies. Potential perspectives and biomarkers are also addressed. We offer this Research Topic involving 64 articles and 501 authors to discuss recent advances regarding: 1. An overview of the human microbiota and its capacity to interact with the human immune system and metabolic processes, 2. New developments in understanding the immune system’s strategies to respond to infections and escape strategies used by pathogens to counteract such responses, 3. The link between the microbiota and pathology in terms of autoimmunity, allergy, cancers and other diseases.

Leading international researchers and clinicians comprehensively review in detail what is known about the ability of diet to enhance human immune function in health, disease, and under various condition of stress. The authors offer state-of-the-art critical appraisals of the influences on the human immune system of several important vitamins and minerals both singly and in combination. The authors also examine how nutrition modulates immune function in various disease states and under three forms of stress-vigorous exercise, military conditions, and air pollution. A much-needed overview of the nutritional consequences of drug-disease interactions provides recommendations for potential nutritional interventions that could increase drug efficacy and/or reduce adverse side effects. "Conclusions" and "Take Home Messages" at the end of each chapter give physicians clinical instructions about special diets and dietary components for many immune-related disease states.

We acknowledge the initiation and support of this Research Topic by the International Union of Immunological Societies (IUIS). We hereby state publicly that the IUIS has had no editorial input in articles included in this Research Topic, thus ensuring that all aspects of this Research Topic are evaluated objectively, unbiased by any specific policy or opinion of the IUIS.

Immunologists today are interested in all of the diverse cell-types involved in host defense and have a deeper appreciation of the importance of innate immune mechanisms as a first line of protection against pathogens. This volume thus discusses the isolation and functional characterization of cells involved in innate immunity in mouse and man, including mast cells and eosinophils. Other focuses include natural killer cells, methods in statistics, in vivo imaging, genome engineering, and mutagenesis and culture that are adapted to the study of innate immunity in these hosts. These are complemented with a series of chapters dealing with alternative models: plants, worms, mosquitoes, flies, and fish. Together, these approaches and models are being used to dissect the complex interplay between hosts and pathogens and contribute to developing strategies to help fight infection. With chapters written by experts on the cutting-edge of this technology, Innate Immunity is an essential reference for immunologists, histologists, geneticists, and molecular biologists.

Dan Chiras once again offers a refreshing and student-friendly introduction to the structure, function, health, and homeostasis of the human body in a modernized ninth edition of Human Biology. This acclaimed text explores life from a variety of levels and perspectives, including cellular/molecular, by body system, through disease, and within the environment.
