C-type Natriuretic Peptide (CNP) is a hormone produced primarily in the brain and vascular endothelium. It plays a crucial role in regulating blood pressure and fluid balance by promoting vasodilation, which helps widen blood vessels. CNP is part of the natriuretic peptide family, which also includes Atrial Natriuretic Peptide (ANP) and B-type Natriuretic Peptide (BNP). CNP is involved in various physiological processes, including inhibiting the growth of smooth muscle cells and promoting the excretion of sodium in urine. Its actions contribute to cardiovascular health and may have therapeutic implications for conditions like heart failure and hypertension.
