From the beginning, immunologists have maintained a unique nomenclature that has often mystified and even baffled their colleagues in other fields, causing them to liken immunology to a black box. With more than 1,200 illustrations that depict every concept of importance, the Illustrated Dictionary of Immunology, Second Edition provides immunologists and nonimmunologists alikea single-volume resource for the many terms encountered in contemporary immunological literature. Encyclopedic in scope, the content ranges from photographs of historical figures to molecular structures of recently characterized cytokines, the major histocompatibility complex molecules, immunoglobulins, and molecules of related interest to immunologists. These descriptive illustrations provide a concise and thorough understanding of the subject. In the years since publication of the first edition, there has been an exponential increase in immunological information and this updated text represents these advances.
