signaling networks

Signaling networks are complex systems of pathways that cells use to communicate and coordinate their actions. They involve molecules, called signals, that travel within or between cells—like messages—triggering specific responses such as growth, movement, or survival. These networks organize how cells react to changes in their environment, ensuring proper function and health. Think of them as a detailed communication system within the body, where signals are the messages, and the network’s structure ensures the right response happens at the right time.
