Question: why is bnp called brain?
Answer: Later on, a new compound from pig brain was found, which had similar natriuretic and diuretic effects as ANP (Sudoh et al., 1988). This peptide was named brain (B-type) natriuretic peptide (BNP) whose actual site of synthesis is the ventricular myocardium (Mukoyama et al., 1991).
