The Expression of the Gene Coding for the Antibacterial Peptide LL-37 Is Induced in Human Keratinocytes during Inflammatory Disorders
Open accessAbstract
The epithelia constitute a major barrier to the environment and provide the first line of defense against invading microbes. Antimicrobial peptides are emerging as participants in the defense system of epithelial barriers in general. Originally we isolated the human antimicrobial peptide LL-37 from granulocytes. The gene (CAMP or cathelicidin antimicrobial peptide) coding for this peptide belongs to the cathelicidin family, whose members contain a conserved pro-part of the cathelin type. The human genome seems to have only one gene of this family, whereas some mammalian species have several cathelicidin genes. In the present work we demonstrate up-regulation of this human cathelicidin gene in inflammatory skin disorders, whereas in normal skin no induction was found. By in situ hybridization and immunohistochemistry the transcript and the peptide were located in keratinocytes throughout the epidermis of the inflammatory regions. In addition, the peptide was detected in partially pure fractions derived from psoriatic scales by immunoblotting. These fractions also exhibited antibacterial activity. We propose a protective role for LL-37, when the integrity of the skin barrier is damaged, participating in the first line of defense, and preventing local infection and systemic invasion of microbes.

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.
