Nitric Oxide Signaling

Meaning

Nitric Oxide (NO) signaling is a critical paracrine and autocrine communication system utilizing the simple, gaseous molecule Nitric Oxide as a potent, short-lived messenger within the body. This signaling pathway is paramount in regulating vascular tone, platelet function, neurotransmission, and immune response. Maintaining robust NO bioavailability is a cornerstone of cardiovascular and metabolic health, often declining with age and endothelial dysfunction.
