Complex Biochemical Signaling

Meaning

The highly intricate and multi-layered network of molecular interactions, including cascades of hormones, growth factors, and neurotransmitters, that govern cellular behavior and systemic homeostasis. This signaling involves numerous parallel and intersecting pathways, enabling cells to integrate diverse external and internal cues to produce a finely tuned physiological response. Dysregulation in this complex system is a hallmark of many chronic diseases and aging, leading to systemic functional decline.
