Cellular Communication Messengers

Meaning

Cellular Communication Messengers are the diverse molecules that facilitate signal transduction between cells, governing all physiological processes within the body. In endocrinology, this group primarily encompasses hormones, neurotransmitters, and cytokines, which transmit information across vast distances or localized cellular environments. These messengers dictate cell fate, metabolism, proliferation, and differentiation, forming the fundamental language of human physiology. Maintaining the clarity and integrity of these signals is paramount for systemic health and optimal function.
