Peptide quantification by liquid chromatography–mass spectrometry (LC–MS) combines the
high resolving power of reversed-phase (RP) chromatography with the excellent selectivity …

We report the isolation and characterization of a novel human peptide with antimicrobial
activity, termed LEAP-1 (liver-expressed antimicrobial peptide). Using a mass spectrometric …

A renal natriuretic peptide and the ‘renal urodilatin system’ were identified after the
observation that immunoassayable ANP in urine may not be identical to the circulating cardiac …

We report the isolation and characterization of a novel peptide with significant sequence
homology to β‐defensins from human blood filtrate. The human β‐defensin‐1 (hBD‐1) is a short …

β‐Defensins are antibiotic peptides involved in host defense at the epithelial surface. Three
human β‐defensins (hBDs)‐‐hBD‐1, hBD‐2, and hBD‐3‐‐have been identified so far. We …

Sexual intercourse is the major route of HIV transmission. To identify endogenous factors
that affect the efficiency of sexual viral transmission, we screened a complex peptide/protein …

Previous studies have shown the implication of β-defensins in host defense of the human
body. The human β-defensins 1 and 2 (hBD-1, hBD-2) have been isolated by biochemical …

A variety of molecules in human blood have been implicated in the inhibition of HIV-1. However,
it remained elusive which circulating natural compounds are most effective in controlling …

Here we report the isolation and characterization of an antibacterial peptide from bovine
milk inhibiting the growth of Escherichia coli, and Staphylococcus carnosus. The primary …

The large intestine of breast‐fed infants is colonized predominantly by bifidobacteria, which
have a protective effect against acute diarrhea. In this study we report for the first time the …
