摘要

Rosacea is one of the most common chronic inflammatory skin diseases that mainly affects the white adult population. The pathophysiology of rosacea is still not completely elucidated. Growing evidence indicates that the aberrant innate immune response might play an essential role in this disease.1Gallo R.L. Granstein R.D. Kang S. et al.Standard classification and pathophysiology of rosacea: the 2017 update by the National Rosacea Society Expert Committee.J Am Acad Dermatol. 2018; 78: 148-155Abstract Full Text Full Text PDF PubMed Scopus (224) Google Scholar S100 proteins are a family of small (9-13 kDa), calcium-binding molecules involved in the regulation of cell signaling, metabolism, and proliferation. A member of the S100 protein family, koebnerisin (S100A15), is an innate, antimicrobial peptide with diverse proinflammatory functions encoded by a gene located within the epidermal differentiation complex on chromosome 1q21. The S100A15 gene is transcribed into 2 alternate mRNA splice variants, the short (S100A15-S) and long (S100A15-L) isoforms, that share the same coding region but are differentially regulated.2Wolf R.

In response to some endogenous or exogenous stimuli, koebnerisin enhances immune-mediated inflammatory processes in the skin.2Wolf R. Ruzicka T. Yuspa S.H.

Dombrowski Y. Zwicker S. et al.Isotretinoin therapy changes the expression of antimicrobial peptides in acne vulgaris.Arch Dermatol Res. 2014; 306: 689-700Google Scholar In inflamed skin, koebnerisin is expressed by various cells, such as keratinocytes, fibroblast, endothelial cells, and dendritic cells.2Wolf R.

The objective of the present study was to investigate the expression and function of koebnerisin in rosacea. The study group consisted of patients with moderate and severe rosacea (n = 6). Skin biopsies were taken from inflammatory, erythematopapular lesions located on the face. All patients were white, had skin of phototype I-III, and were 47-66 (mean ± standard deviation 56.83 ± 7.03) years of age. The control group was matched by race, sex, and age and consisted of healthy volunteers who underwent facial plastic surgery procedures (n = 6). The expression of koebnerisin in skin lesions of patients with rosacea and controls was assessed by quantitative reverse transcription PCR and immunofluorescent analysis. The regulation and function of koebnerisin in rosacea-relevant human skin cell cultures, keratinocytes, and fibroblasts were assessed by quantitative reverse transcription PCR. In the present study, we found that koebnerisin was upregulated in rosacea lesional skin compared with healthy skin (Fig 1). Koebnerisin was overexpressed in the epidermis by suprabasal and basal keratinocytes as well as in the dermis. The upregulation of koebnerisin in the epidermis suggests its potential role in the regulation of keratinocytes proliferation and function. Moreover, by being overexpressed in rosacea skin lesions, koebnerisin might exert a proinflammatory effect. A previously conducted study showed that koebnerisin acts as a chemoattractant for monocytes and neutrophils, which play a significant role in the pathogenesis of rosacea.3Wolf R. Howard O.M. Dong H.F. et al.Chemotactic activity of S100A7 (Psoriasin) is mediated by the receptor for advanced glycation end products and potentiates inflammation with highly homologous but functionally distinct S100A15.J Immunol. 2008; 181: 1499-1506Crossref PubMed Scopus (136) Google Scholar Furthermore, it has been demonstrated that koebnerisin has the ability to prime keratinocytes and leukocytes for enhanced production of proinflammatory cytokines, eg, tumor necrosis factor α (TNF-α), interleukin (IL) 6, IL-8, and IL-1β.4Hegyi Z.

In the present study, we also showed that koebnerisin might play an additional proangiogenic role stimulating keratinocytes and fibroblasts to enhance the production of the potent proangiogenic mediator vascular endothelial growth factor, and we further demonstrated that koebnerisin primed fibroblasts for increased expression of matrix metalloproteinase 9 (Fig 2, C-F). Matrix metalloproteinase 9 has a destructive effect on dermal components and, thus, stimulates the innate immune response and inflammatory processes.1Gallo R.L. Granstein R.D.
