At a Glance series sets out to summarise the essential information about a particular subject for the student requiring a quick introduction or a guide to revision. This is achieved by taking each part of the subject in turn and condensing it into a two-page spread with a schematic diagram on the left and a concise explanation on the right. This book presents a broad look at immunology with the aid of a series of thoughtfully constructed sketches to show the mechanisms involved in immunological processes. It covers: the scope of immunology cellular and hormonal factors immunology of infectious disease antibody formation, structure and function immunology of cancer hypersensitivity autoimmunity and immunodeficiency. The sixth edition features two new spreads on antigen recognition and processing, and cell interactions which together comprise the antibody response which is now divided into two sections. Throughout this new edition, the major emphasis has been the advances of our knowledge of the genetic basis of immunology. The appendix of CD classification has also been updated.
