Emphasizes the fundamental concepts and principles of human immunology that students need to know, without overwhelming them with extraneous material. It leads the reader to a firm understanding of basic principles, using full-color illustrations; short, easy-to-read chapters; color tables that summarize key information clinical cases; and much moreall in a conveniently sized volume that's easy to carry. Presents all of the most important principles that govern the function of the immune system. Extrapolates key concepts from the vast amount of experimental data that has emerged. Focuses on the cellular interactions in immune responses rather than describing in detail many of the underlying biochemical and molecular mechanisms. Emphasizes immune responses in human rather than experimental animals, drawing upon parallels with experimental situations only when necessary. Uses illustrations, diagrams, figures, charts and tables to highlight important principles, and illustrates.
