The Third Edition of the Cytokine Handbook provides encyclopedic coverage of the hemopoietic growth factors and the interleukin and interferon families of molecules, cytokine by cytokine. This new edition is completely revised to bring the reader the most up-to-date information on all of the important cytokines and cytokine receptors with the inclusion of new members of the interleukin family (up to IL-18), in depth treatment of cytokine receptors, as well as individual chapters on stem cell factor and flt3 ligand, gene therapy, and the chemokines. The Cytokine Handbook explains in detail the immunology and molecular biology of these molecules and their receptors, and discusses in additional chapters their therapeutic potential, assay systems, and phylogeny. It is written in an easy-to-follow style and includes an extensive bibliography. This book is a must for the library of any researcher or clinician interested in, or bewildered by, the diversity of cytokines.
