Bio-Signaling Compounds

Meaning

Molecules that serve as crucial transmitters of information, communicating between cells or operating within a cell, thereby initiating a precisely controlled cascade of biochemical responses that regulate all physiological processes. This broad and vital category encompasses classical hormones, complex neurotransmitters, localized cytokines, essential growth factors, and other intercellular messengers. These compounds are fundamental to the coordinated function of the endocrine, nervous, and immune systems, orchestrating the body’s complex life processes.
