Cutaneous Injury Induces the Release of Cathelicidin Anti-Microbial Peptides Active Against Group A Streptococcus
Open accessAbstract
Cathelicidins are a family of peptides thought to provide an innate defensive barrier against a variety of potential microbial pathogens. The human and mouse cathelicidins (LL-37 and CRAMP, respectively) are expressed at select epithelial interfaces where they have been proposed to kill a number of gram-negative and gram-positive bacteria. To determine if these peptides play a part in the protection of skin against wound infections, the anti-microbial activity of LL-37 and CRAMP was determined against the common wound pathogen group A Streptococcus, and their expression was examined after cutaneous injury. We observed a large increase in the expression of cathelicidins in human and murine skin after sterile incision, or in mouse following infection by group A Streptococcus. The appearance of cathelicidins in skin was due to both synthesis within epidermal keratinocytes and deposition from granulocyctes that migrate to the site of injury. Synthesis and deposition in the wound was accompanied by processing from the inactive prostorage form to the mature C-terminal peptide. Analysis of anti-microbial activity of this C-terminal peptide against group A Streptococcus revealed that both LL-37 and CRAMP potently inhibited bacterial growth. Action against group A Streptococcus occurred in conditions that typically abolish the activity of anti-microbial peptides against other organisms. Thus, cathelicidins are well suited to provide defense against infections due to group A Streptococcus, and represent an important element of cutaneous innate immunity.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
