Lactoferricin Kills Bacteria by Bending Their Membranes: Curvature Stress Mechanism

In VitroPreliminary evidence
The takeaway

Lactoferricin derivatives induced membrane curvature stress in bacterial membranes as their killing mechanism, with the degree of membrane bending correlating with antimicrobial potency.

Key finding

Lactoferricin derivatives killed bacteria by inducing membrane curvature stress (lipid phase transitions), with peptide-induced negative curvature str

What the researchers found

Lactoferricin derivatives killed bacteria by inducing membrane curvature stress (lipid phase transitions), with peptide-induced negative curvature strain correlating with antimicrobial activity — a biophysical mechanism beyond simple pore formation.

Why it matters
