Cell Signalling

Cell Signalling provides an introduction to signalling within and between cells—one of the most important aspects of biochemistry and cell biology. It is composed of four parts, and Part 1 provides an overview of signalling and looks at the history and techniques of cell signalling. Part 2 considers components that comprise signalling pathways. For example, this part looks at extracellular signals, such as hormones, and discusses the detection of extracellular signals. Part 3 centres on selected examples of signalling pathways and events. These include insulin and the signal transduction cascades it invokes; perception of the environment; signalling in development and for the regulation of gene expression; and life, death, and apoptosis. The last part presents some final thoughts on cell signalling and looks to the future.
