How Antimicrobial Peptides Choose Bacterial vs Human Membranes: The Lipid Selectivity Rules
Antimicrobial peptide-lipid binding studies revealed the molecular basis for selectivity: electrostatic attraction to bacterial anionic lipids combined with hydrophobic insertion patterns that differ between bacterial and human membranes.
Quick Facts
What This Study Found
Antimicrobial peptide selectivity for bacteria depends on preferential electrostatic binding to anionic bacterial membrane lipids (PG, CL) over zwitterionic human membrane lipids (PC, SM), with hydrophobic insertion depth determining killing efficiency — the molecular basis for therapeutic selectivity.
