This book is intended as an introductory text for use in immunology courses for medical students, advanced undergraduate biology students, graduate students, and scientists in other fields who want to know more about the immune system. It attempts to present the field of immunology from a consistent viewpoint, that of the host’s interaction with an environment containing many species of potentially harmful microbes. The justification for this approach is that the absence of one or more components of the immune system is virtually always made clear by an increased susceptibility to one or more specific infections. Thus, first and foremost, the immune system exists to protect the host from infection, and its evolutionary history must have been shaped largely by this challenge. Other aspects of immunology, such as allergy, autoimmunity, graft rejection, and immunity to tumors, are treated as variations on this basic protective function. In these cases the nature of the antigen is the major variable.
