Despite rapidly increasing interest in developmental immunotoxicology, there is not yet a textbook focused on this hot area of research. Developmental Immunotoxicology fills the void with overviews of immune system development in experimental animal and human models, and discusses the complex issues related to the evolution of developmental immunology and risk assessment. This text describes different models used to study developmental immunotoxicology and examples of specific developmental immunotoxic agents, including therapeutics. The text concludes with several chapters that describe the role of neuroimmune interactions as they relate to developmental immunotoxicology. Using a didactic approach, Developmental Immunotoxicology provides an explanatory overview of this cutting-edge field for toxicologists, immunologists, and developmental biologists. It provides a lucid account of this area of research-proposing answers to some questions and stimulating debate on those questions yet to be addressed by the research community.
