Abstract
Human neutrophil peptide-1 (HNP-1), a defensin with antimicrobial properties, is also thought to promote wound healing. To elucidate the mechanism by which wound healing is facilitated by this factor, we investigated the effect of HNP-1 on the expression of interstitial collagenase (matrix metalloproteinase 1, MMP-1), collagen types I and III, and tissue inhibitor of metalloproteinase 1 (TIMP-1) by cultured fibroblasts by means of RT-PCR and ELISA. Our results showed that synthetic HNP-1 increased the expression of proα1(I) collagen mRNA and protein. In contrast, the expression of MMP-1 was decreased at both the mRNA and protein levels. Our observations suggest that HNP-1 may promote wound repair by enhancing extracellular matrix deposition and by controlling its degradation.
