Cell Signalling starts with a brief history and general principles of cell signalling. It then turns to an examination of signals and their perception. It also discusses modifications to proteins that control cell signalling. Next, it looks at intracellular signals. The text also covers cell development before explaining cell signalling disorders, cancers, and apoptosis. Towards the end, the text moves on to stress responses and the changing cell environment. Finally, the book looks to the future, including challenges and perspectives in cell signalling, such as how its manipulation may enable new medical treatments or increase efficiency in agriculture.
