Intracellular signaling

Intracellular signaling refers to the communication that occurs within a cell to help it respond to various stimuli and maintain its functions. When a cell receives a signal, such as a hormone or nutrient, it triggers a series of chemical reactions inside. These reactions involve proteins and other molecules that work together like a relay team, passing messages along pathways to initiate processes like growth, division, or metabolism. This internal signaling network is crucial for cells to adapt to changes, coordinate activities, and ensure overall health and functionality.
