How the Immune System Works is not a comprehensive textbook. It’s the book thousands of students have used to help them understand what’s in their big, thick, immunology texts. In this book, Dr. Sompayrac cuts through the jargon and details to reveal, in simple language, the essence of this complex subject. Fifteen easy to follow lectures, featuring the uniquely popular humorous style and engaging analogies developed by Dr Sompayrac, provide an introduction to the ‘bigger picture’, followed by practical discussion on how each of the components interacts with one another. Now featuring full-color diagrams, this book has been rigorously updated for its fourth edition to reflect today’s immunology teaching and includes updated discussion of B and T cell memory, T cell activation, vaccines, immunodeficiency, and cancer. Whether you are completely new to immunology, or require a refresher, How the Immune System Works is an enjoyable way of engaging with the key concepts – you need know nothing of the workings of the immune system to benefit from this book! How the Immune System Works is now accompanied by a FREE enhanced Wiley Desktop Edition - the interactive, digital version of the book - featuring downloadable text and images, highlighting and note taking facilities, book-marking, cross-referencing, in-text searching, and linking to references and glossary terms. It is also available from CourseSmart for instant, online and offline access for studying anytime, anywhere.
