Effect of CM15 on Supported Lipid Bilayer Probed by Atomic Force Microscopy
Membranes, 2023 Antimicrobial peptides are key components of the immune system. These peptides affect the membrane in various ways; some form nano-sized pores, while others only produce minor defects.

Antimicrobial Peptide-Lipid Binding Interactions and Binding Selectivity [PDF]
Biophysical Journal, 2007 Surface pressure measurements, external reflection-Fourier transform infrared spectroscopy, and neutron reflectivity have been used to investigate the lipid-binding behavior of three antimicrobial peptides: melittin, magainin II, and cecropin P1. As expected, all three cationic peptides were shown to interact more strongly with the anionic lipid, 1,2 ...

Antimicrobial Tear Lipids in the Ocular Surface Defense
Frontiers in Cellular and Infection Microbiology, 2022 The concept of antimicrobial lipids as effectors of innate host defense is an emerging field. There is limited knowledge on the antimicrobial role of lipids in the ocular environment. Tears act as first line of defense to protect the ocular surface from infections.

mBio, 2022 AbstractThe bacterial cell membrane is an interface for cell envelope synthesis, protein secretion, virulence factor assembly and a target for host cationic antimicrobial peptides (CAMPs). To resist CAMP killing, several Gram-positive pathogens encode the multiple peptide resistance factor (MprF) enzyme that covalently attaches cationic amino acids to ...

Effects of Calcium Ions on the Antimicrobial Activity of Gramicidin A
Biomolecules, 2022 Gramicidin A (gA) is a linear antimicrobial peptide that can form a channel and specifically conduct monovalent cations such as H+ across the lipid membrane.

Lipid Clustering by Antimicrobial Polymers and Lectins [PDF]
Biophysical Journal, 2017 The current urge to understand the role of lipids in defense against pathogens is driven by two strategies: killing pathogens and protecting the cell from infection. Antimicrobial peptides and antimicrobial polymers offer a promising alternative to classical antibiotics through their action on membrane integrity.
