Antimicrobial Peptide in Human Blood Ultrafiltrate

Liver-Expressed Antimicrobial Peptide 2 (Human) LEAP-2 [prepro LEAP-2 (38-77)] exerts antibacterial activities against Gram-positive, Gram-negative bacteria, and yeast (IC50 value was around 5 µM against Saccharomyces. cerevisiae). Interestingly, the amino-terminally truncated form, prepro-LEAP-2 (44-77), has not affected the viability of the germs tested. This 40 amino acid residue peptide, LEAP-2, has been reported to be circulating in human blood. LEAP-2 should prove to be variable in studying its role in self-defense in humans, as well as its role as an antibacterial peptide in the family of the well-established α-/β-defensin.
