"This introductory text has been designed for use in immunology courses for undergraduate, medical, dental, and pharmacy students. It synthesizes the established facts of immunology into a comprehensible, coherent, and up-to-date account of how the immune system works. The human immune system is emphasized throughout, and the text has been designed to connect the established discoveries of basic research with the practicalities of clinical immunology. For the second edition, the book has been updated throughout, and now includes end-of-chapter questions to test the reader's mastery of important topics. Detailed answers to all questions are provided in the back of the book. The second edition also features enhanced and revised treatment of the complement system, including new figures and icons to clarify concepts; and even greater emphasis on human immunity; increased coverage of human genetics throughout; and expanded treatment of innate immunity, particularly the mucosal system."--BOOK JACKET.
