Effect of antimicrobial peptides derived from human cathelicidin LL-37 on Entamoeba histolytica trophozoites.
The human cathelicidin hCAP18/LL-37 is an antimicrobial protein consisting of a conserved N-terminal prosequence called the cathelin-like domain and a C-terminal peptide called LL-37. This peptide contains 37 amino acid residues, and several truncated variants obtained from natural sources or by chemical synthesis differ in their capability to damage Gram positive and Gram negative bacteria as ...
متن کاملCathelicidin-BF, a Snake Cathelicidin-Derived Antimicrobial Peptide, Could Be an Excellent Therapeutic Agent for Acne Vulgaris
Cathelicidins are a family of antimicrobial peptides acting as multifunctional effector molecules in innate immunity. Cathelicidin-BF has been purified from the snake venoms of Bungarus fasciatus and it is the first identified cathelicidin antimicrobial peptide in reptiles. In this study, cathelicidin-BF was found exerting strong antibacterial activities against Propionibacterium acnes. Its min...
متن کاملAntibacterial activities of the cathelicidins prophenin (residues 62 to 79) and LL-37 in the presence of a lung surfactant preparation.
The antibacterial activities of the cathelicidin peptides LL-37 and an 18-residue C-terminal fragment of prophenin, corresponding to positions 62 to 79 of native prophenin (PF-18), were analyzed in the presence of a modified surfactant preparation isolated from minced porcine lungs. At low micromolar concentrations, both LL-37 and PF-18 showed significant activities against different serotypes ...
متن کاملHuman cathelicidin, hCAP-18, is processed to the antimicrobial peptide LL-37 by extracellular cleavage with proteinase 3.
Cathelicidins are a family of antimicrobial proteins found in the peroxidase-negative granules of neutrophils. The known biologic functions reside in the C-terminus, which must be cleaved from the holoprotein to become active. Bovine and porcine cathelicidins are cleaved by elastase from the azurophil granules to yield the active antimicrobial peptides. The aim of this study was to identify the...
متن کاملSkin infection management using novel antibacterial agents.
Pseudomonas aeruginosa and methicillin-resistant Staphylococcus aureus (MRSA) cause difficulties in the management of skin and soft tissue infections and have led to morbidity and mortality in hospital-acquired infections especially in susceptible individuals, those who are generally sick or immunosuppressed. Currently approaches in antibacterial agents offer opportunities to manage the trouble...
