Biomolecular Signaling

Meaning

Biomolecular signaling refers to the intricate process by which cells communicate with one another and respond to changes in their internal or external environment. This fundamental physiological process involves the transmission of information through specific molecules, such as hormones, neurotransmitters, and growth factors. It is the cellular language essential for coordinating complex systemic functions, including metabolism, reproduction, and stress response. Proper signaling ensures homeostasis and allows the endocrine system to maintain its delicate balance across the lifespan.
