Endogenous Signaling Agents

Meaning

Endogenous Signaling Agents are a diverse and essential group of biologically active molecules, including hormones, peptides, neurotransmitters, and cytokines, that are naturally produced and secreted within the body to regulate cellular activity and systemic homeostasis. These agents function as internal communicators, transmitting precise, time-sensitive instructions between cells, tissues, and organs via specific receptor interactions. They orchestrate all facets of human physiology, from mood regulation and metabolic rate to growth and reproductive cycles. Their proper synthesis, transport, and balanced action are central to overall health and optimal wellness.
