Biological Signaling

Meaning

Biological signaling refers to the complex system of communication that governs all cellular activities within an organism, enabling cells to perceive and respond to their environment and to each other. This intricate network involves the production, release, and detection of chemical messengers, such as hormones, neurotransmitters, and growth factors. Effective biological signaling is fundamental to maintaining physiological homeostasis, coordinating development, and facilitating adaptive responses to stress or disease. Disruptions in these pathways are central to the pathogenesis of many chronic conditions, including endocrine disorders and metabolic syndrome.
