Bacterial membrane lipids in the action of antimicrobial agents
Journal of Peptide Science, 2010AbstractMany antimicrobial agents that target bacteria are cationic and can interact with the anionic lipid components that are exposed on the bacterial membrane. Bacteria vary widely in the nature of the major lipid components that are in the cell membrane.

Antimicrobial Lipids from the Hemolymph of Brachyuran Crabs
Applied Biochemistry and Biotechnology, 2009The potential of marine crabs as a source of biologically active products is largely unexplored. In the present study, antimicrobial activity of the hemolymph (plasma) and hemocytes (plasma cells) of six brachyuran crabs was investigated against 16 pathogenic strains.

Lipid-Based Nanopharmaceuticals in Antimicrobial Therapy
2017Nanotechnology and its direct application in medicine offer a platform for advanced therapeutic strategies against infections. The small size of nanosystems (nanocarriers) distinguishes their features from other delivery systems since nanocarriers may penetrate biological membranes, improve drug bioavailability, assure cellular internalization and ...

Antimicrobial lipids in nano-carriers for antibacterial delivery
Journal of Drug Targeting, 2019Antimicrobial lipids have been recognised as broad-spectrum antibacterial agents. They can directly act on and lyse bacterial cell membrane, and inhibit bacterial growth through a range of mechanisms. Antimicrobial lipids include free fatty acids, monoglycerides, cholesteryl ester, sphingolipids and etc., with the first two being the most extensively ...

Antimicrobial Particles from Cationic Lipid and Polyelectrolytes
Langmuir, 2010Hybrid nanoparticles from cationic lipid and polymers were prepared and characterized regarding physical properties and antimicrobial activity. Carboxymethylcellulose (CMC) and polydiallyldimethylammonium chloride (PDDA) were sequentially added to cationic bilayer fragments (BF) prepared from ultrasonic dispersion in water of the synthetic and cationic

Role of lipids in the interaction of antimicrobial peptides with membranes
Progress in Lipid Research, 2012Antimicrobial peptides (AMPs) take part in the immune system by mounting a first line of defense against pathogens. Recurrent structural and functional aspects are observed among peptides from different sources, particularly the net cationicity and amphipathicity. However, the membrane seems to be the key determinant of their action, either as the main

Disturbances of antimicrobial lipids in atopic dermatitis
JDDG: Journal der Deutschen Dermatologischen Gesellschaft, 2006SummaryPatients with atopic dermatitis exhibit an increased susceptibility to cutaneous infections, especially to pathological colonization with superantigen‐secreting Staphylococcus aureus. Recent attention has been focused on antimicrobial peptides, especially on cathelicidin and human β‐defensin‐2, which are under‐expressed in atopic skin ...

The Antimicrobial Function of Milk lipids
2010Milk lipids serve not only as nutrients but as antimicrobial agents that constitute a defense system against microbial infections that occur at mucosal surfaces. The lipid fraction of milk develops antimicrobial activity in the gastrointestinal tract of suckling neonates as a result of lipolytic activity which converts milk triglycerides to ...

The most obvious function of the sebaceous gland is to excrete sebum [1, 2]. For a long time hyperseborrhea has been considered as a major etiopathogenetic factor for the development of acne. However, current research provides evidence that sebum quantity per se cannot be the only responsible factor, as demonstrated by the success of treatment with ...
