There are multiple definitions:

1. C-type natriuretic peptide(English)

   • represents the paracrine element of the natriuretic peptide axis which complements the endocrine actions of atrial natriuretic peptide and brain natriuretic peptide. It is produced by the endothelium and appears to play a prominent role in vascular and cardiac function, both physiologically and pathologically. This provides a rationale for the therapeutic potential of pharmacological interventions targeted to CNP signalling
