Signal Transduction

Signal transduction is the process in which cellular signals are transmitted from outside the cell, across the cell membrane and into the cell, and then further mediated inside the cell. It plays an important role in cellular communication as it helps to relay signals to the cell and inform it of changes in its environment. Signal transduction is integral for biological processes including cell growth and differentiation, development, immunity and homeostasis. Its significance is especially evident in the development of cancer, where it can be used to help pinpoint what pathways are disrupted within the cell and by which molecules, allowing medical professionals to more accurately diagnose and treat the disease. Ultimately, signal transduction is critical to understanding the complex biological mechanisms that underpin many aspects of life.
