Book excerpt: This volume in the Current Topics in Membranes series discusses the biology of chemokines and their binding partners, chemokine receptors, in normal and disease-related states. Chemokines are small proteins that are important in normal immune responses. Recent research demonstrates a role for these proteins in a variety of diseases such as heart disease, allergy, asthma, and cancer. As a result of the discovery of this link to disease, the topic of chemokines and drugs that block their actions has become an intense are of study. This book presents the topics of chemokines, chemokine receptors, and related pathologies in an integrated manner that provides the reader with a comprehensive and up-to-date knowledge of these topics. Provides a comprehensive overview of the history, molecular biology, cell biology, pharmacology, physiology, and pathophysiology of chemokines and their receptors Each chapter discusses "future directions and unanswered questions" of chemokine biology Serves as a road map for future research
