Endogenous Signaling

Meaning

Endogenous signaling refers to the complex communication processes that originate from within the organism itself, utilizing native molecules such as hormones, cytokines, and neurotransmitters to transmit information between cells and tissues. This intrinsic system ensures physiological homeostasis, coordinating functions from metabolism and reproduction to stress response and immune regulation. Understanding these internal signals is paramount for clinical intervention in endocrine disorders.
