C-Type Natriuretic Peptide (CNP) is a hormone produced primarily in the brain and blood vessels. It plays a crucial role in regulating blood pressure and fluid balance in the body. CNP helps to dilate blood vessels, which can lower blood pressure and promote the excretion of sodium through urine. CNP is part of the natriuretic peptide family, which includes Atrial Natriuretic Peptide (ANP) and B-Type Natriuretic Peptide (BNP). These peptides are involved in cardiovascular health and are often studied for their potential roles in heart disease and other conditions related to fluid overload.
