What the researchers found
Lactoferricin-derived peptides bound bacterial LPS and showed antimicrobial activity against E. coli including LPS mutant strains, with activity correlating with LPS binding — confirming membrane interaction as the killing mechanism.
Why it matters
Advances understanding in antimicrobial-peptides, infection, receptor-signaling research.
