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 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.

Thematic Review Series: Skin Lipids. Antimicrobial lipids at the skin surface [PDF]

Journal of Lipid Research, 2008
The skin surface represents our interface with the external environment, and as such, is our first line of defense against microbial colonization and infection. Lipids at the skin surface are thought to underlie at least part of an antimicrobial barrier.

Trehalose Lipid Biosurfactant Reduces Adhesion of Microbial Pathogens to Polystyrene and Silicone Surfaces: An Experimental and Computational Approach

Frontiers in Microbiology, 2018
Rhodococcus fascians BD8, isolated from Arctic soil, was found to produce biosurfactant when grown on n-hexadecane as the sole carbon source. The glycolipid product was identified as the trehalose lipid with a molecular mass of 848 g mol−1.

Antimicrobial Lipids from Plants and Marine Organisms: An Overview of the Current State-of-the-Art and Future Prospects

Antibiotics, 2020
In the actual post-antibiotic era, novel ways of rethinking antimicrobial research approaches are more urgent than ever. Natural compounds with antimicrobial activity such as fatty acids and monoacylglycerols have been investigated for decades ...

Study of the Physicochemical and Biological Properties of the Lipid Complex of Marine Microalgae Isolated from the Coastal Areas of the Eastern Water Area of the Baltic Sea

Molecules, 2022
The Baltic Sea algae species composition includes marine euryhaline, freshwater euryhaline, and true brackish water forms. This study aimed to isolate a lipid–pigment complex from microalgae of the Baltic Sea (Kaliningrad region) and investigate its ...

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.

Polymyxin Resistance and Heteroresistance Are Common in Clinical Isolates of Achromobacter Species and Correlate with Modifications of the Lipid A Moiety of Lipopolysaccharide

Microbiology Spectrum, 2023
The Achromobacter genus includes opportunistic pathogens that can cause chronic infections in immunocompromised patients, especially in people with cystic fibrosis (CF). Treatment of Achromobacter infections is complicated by antimicrobial resistance. In

Lipids and the Permeability and Antimicrobial Barriers of the Skin

Journal of Lipids, 2018
The primary purpose of the epidermis of terrestrial vertebrates is to produce the stratum corneum, which serves as the interface between the organism and the environment. As such, the stratum corneum provides a permeability barrier which both limits water loss through the skin and provides a relatively tough permeability barrier.
