Signaling Molecules
Signaling molecules are substances which are released between cells in the body and act as a means of communication. They control cell development, differentiation and behavior, alerting other cells to start or stop certain actions. They are essential for cell growth and organ formation. They are particularly important in the immune system where they trigger the response to foreign invaders or stimulate tissue healing. They are also crucial in the endocrine system, where they are responsible for hormone production and regulation of metabolism. Signaling molecules have numerous applications in medicine, such as cancer treatments, and they are important in biological research, to further our understanding of how cells communicate with each other.
