This review presents the current state of knowledge regarding multifunctional role of human skin antimicrobial peptides (AMPs), including (a) protection from microbial infection, (b) improvement of skin barrier homoeostasis, (c) modulation of inflammation responses, and (d) promotion of wound healing. In addition, association of AMPs with skin Antimicrobial peptides and the skin In recent years, hundreds of naturally occurring peptide antibiotics have been discovered based on their ability to inhibit the growth of microbial pathogens. These antimicrobial peptides (AMPs) participate in the innate immune response by providing a rapid first-line defence against infection. Despite these microbial threats, skin is surprisingly highly resistant against infections. Various studies in the last decade discovered a chemical cutaneous defense system based on the production of antimicrobial proteins. These antimicrobial proteins act as a first defense line through their broad spectrum of potent antimicrobial activity.

Skin secretions from many species of anurans (frogs and toads) are a rich source of peptides with broad-spectrum antimicrobial activities that may be developed into agents with therapeutic potential, particularly for topical applications. 2002-03-01 · Two groups of antimicrobial peptides have been isolated from skin secretions of Bombina maxima. Peptides in the first group, named maximins 1, 2, 3, 4 and 5, are structurally related to bombinin-like peptides (BLPs). Unlike BLPs, sequence variations in maximins occurred all through the molecules. While tylotoin, a peptide from salamander skin with no antimicrobial activity, increased recruitment of macrophages to the wound site and promoted transforming growth factor (TGF)-β release from macrophages (Mu et al., 2014), the peptide CW49 from frog skin reduced macrophage recruitment and secretion of pro-inflammatory cytokines and might thus be used for the treatment of non-healing wounds The antimicrobial peptide cathelicidin (LL-37) is expressed in eccrine and duct cells in the skin as well as mast cells and respiratory epithelial cells in the lung and gut, under inflammatory This article is an overview of antimicrobial peptides found in anurans skin secretions.

Its cellular source is the keratinocyte, which terminally differentiates in the uppermost parts of the skin, eventually forming the stratum corneum, the horny layer. Other peptides with antimicrobial activity, such as adrenomedullin [53], cystatin [54], secretory leukocyte protease inhibitor [55] and neutrophil gelatinase-associated lipocalin [56], have also been observed in skin. A wide variety of skin conditions have been examined for changes in the expression pattern of AMPs. Cathelicidin is Se hela listan på Se hela listan på 2011-04-01 · Antimicrobial peptides belonging to the peptide glycine–leucine–amide family have been isolated from skin secretions of X. laevis (PGLa), X. amieti (PGLa-AM1 and PGLa-AM2), X. borealis (PGLa-B1 and PGLa-B2), and S. tropicalis (peptide XT-5) [reviewed in (Mechkarska et al., 2010)] but an ortholog was not identified in the X. clivii secretions.

These features of AMPs are actively involved in maintaining of the skin barrier homeostasis. In the skin, both resident and infiltrating cells synthesize and secrete small peptides that demonstrate broad-spectrum antimicrobial activity against bacteria, fungi, and enveloped viruses. Antimicrobial peptides also act as multifunctional immune effectors by stimulating cytokine and chemokine production, angiogenesis, and wound healing.
