Signaling within and between cells is one of the most important aspects of modern biochemistry and cell biology. An understanding of signalling pathways is vital to a wide range of biologists, from those who are investigating the causes of cancer, to those who are concerned about the impact of environmental pollutants on the ecosystem. The way cells adapt to changing environments, and the way cell dysfunction causes disease, is underpinned by cell signalling events. presents a carefully structured and highly accessible introduction to this intricate and rapidly growing field. Starting with an overview of cell signalling and highlighting its importance in many biological systems, the book goes on to explore the key components of extracellular and intracellular signalling mechanisms, before examining how these components come together to create signalling pathways. A focus on common components and concepts, rather than mechanistic detail, allows the reader to gain a thorough understanding of the principles that underpin cell signalling.
