Human natriuretic peptides exhibit antimicrobial activity

Eur J Med Res. 2001 May 29;6(5):215-8.


Here we describe a novel function for members of the well-characterized human natriuretic peptide family. Human "brain-type natriuretic peptide" (hBNP-32) as well as other members of this peptide class are antimicrobially active against Gram-positive and Gram-negative bacteria and yeast in a dose-dependent manner. This activity of natriuretic peptides is comparable to that of known antimicrobial peptides such as casocidins or magainins.
