Infos

Signal Transduction is a well-illustrated, coherent look at cellular signaling processes. Beginning with the basics, it explains how cells respond to external cues, hormones, growth factors, cytokines, cell surfaces, etc., and then shows how these inputs are integrated and coordinated. The extensive color artwork provides the reader with a clearer comprehension of key topics, and margin notes are incorporated to highlight milestones in the evolution of signal transduction. This book serves as an invaluable resource for advanced undergraduates, graduate researchers, and established scientists working in cell biology, pharmacology, immunology, and related fields.

Key Features
* Coherent, precise text providing insight in depth to a subject that is central to cell biology and fundamental to many areas of biomedicine
* Extensive conceptual colour artwork assists with the comprehension of key topics
* Extensive referencing provides an invaluable link to the core and historical literature
* Margin notes highlighting milestones in the evolution of our understanding of signalling mechanisms
