Elastin microfibril interface-located protein 1 in fibroblasts is regulated by amphiregulin and interleukin-1α produced by keratinocytes
Objective
The structure of elastic fibres changes with ageing. Elastin microfibril interface–located protein 1 (EMILIN-1) is known to contribute to structural changes in elastic fibres. EMILIN-1 is one of the components of elastic fibres and also colocalizes with oxytalan fibres near the epidermis. Therefore, EMILIN-1 may be affected by epidermal–dermal interactions. The purpose of this study is to identify the key factors involved in epidermal–dermal interactions during the structural degeneration of elastic fibres.
Methods
Keratinocytes and fibroblasts were co-cultured, and changes in elastic fibre-related proteins were evaluated. Additionally, cytokine arrays were used to identify the factors involved in epidermal–dermal interactions.
Results
EMILIN-1 expression in fibroblasts was increased in the presence of keratinocytes, and its expression decreased when keratinocytes were stressed. Amphiregulin (AREG) and interleukin-1α (IL-1α) were identified as the keratinocyte-derived cytokines that influence the production of EMILIN-1, which is secreted by the fibroblasts. EMILIN-1 expression was promoted by AREG and decreased by IL-1α via an increase in cathepsin K (a catabolic enzyme). AREG and IL-1α were associated with changes in EMILIN-1 levels in fibroblasts.
Conclusion
The findings suggest that the suppression of IL-1α expression and promotion of AREG expression in the epidermis could be a new approach that prevents the wrinkles and sagging caused by the structural changes in elastic fibres.
期刊介绍:
The Journal publishes original refereed papers, review papers and correspondence in the fields of cosmetic research. It is read by practising cosmetic scientists and dermatologists, as well as specialists in more diverse disciplines that are developing new products which contact the skin, hair, nails or mucous membranes.
The aim of the Journal is to present current scientific research, both pure and applied, in: cosmetics, toiletries, perfumery and allied fields. Areas that are of particular interest include: studies in skin physiology and interactions with cosmetic ingredients, innovation in claim substantiation methods (in silico, in vitro, ex vivo, in vivo), human and in vitro safety testing of cosmetic ingredients and products, physical chemistry and technology of emulsion and dispersed systems, theory and application of surfactants, new developments in olfactive research, aerosol technology and selected aspects of analytical chemistry.
