Dermcidin-derived peptides show a different mode of action than the cathelicidin LL-37 against Staphylococcus aureus.
Dermcidin (DCD) is an antimicrobial peptide which is constitutively expressed in eccrine sweat glands. By postsecretory proteolytic processing in sweat, the DCD protein gives rise to anionic and cationic DCD peptides with a broad spectrum of antimicrobial activity. Many antimicrobial peptides induce membrane permeabilization as part of their killing mechanism, which is accompanied by a loss of ...
متن کاملThe Human Antimicrobial Peptides Dermcidin and LL-37 Show Novel Distinct Pathways in Membrane Interactions
Mammals protect themselves from inflammation triggered by microorganisms through secretion of antimicrobial peptides (AMPs). One mechanism by which AMPs kill bacterial cells is perforating their membranes. Membrane interactions and pore formation were investigated for α-helical AMPs leading to the formulation of three basic mechanistic models: the barrel stave, toroidal, and carpet model. One m...
متن کاملEvaluating the Antiviral Activities of Human Cathelicidin LL-37 Peptide Against Rotavirus in Vitro
Background Rotavirus is the most prevalent cause of severe gastroenteritis, hospitalizations, and deaths among infants and young children, globally. No specific antiviral drug is available against rotavirus infection. Objective The current study aimed to assess the antiviral effect of human cathelicidin antimicrobial peptide LL-37 on rotavirus infection in vitro. Methods This study was con...
متن کاملEffect 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 کاملAntiviral Activity of the Human Cathelicidin, LL-37, and Derived Peptides on Seasonal and Pandemic Influenza A Viruses
Human LL-37, a cationic antimicrobial peptide, was recently shown to have antiviral activity against influenza A virus (IAV) strains in vitro and in vivo. In this study we compared the anti-influenza activity of LL-37 with that of several fragments derived from LL-37. We first tested the peptides against a seasonal H3N2 strain and the mouse adapted H1N1 strain, PR-8. The N-terminal fragment, LL...
