Megjegyzések:	Retinoid-X receptor (RXR)- and retinoic acid receptor (RAR)-mediated signaling is induced by retinoic acids (RA), which are involved in the regulation of skin permeability, differentiation and immune response. Dysregulation of retinoid signaling is present in various skin disorders. Topically and systemically administered synthetic RAR or RXR agonists might influence retinoid-mediated signaling in the skin of RARE reporter animals and gene expression analysis for retinoid, skin homeostasis and skin inflammation marker genes and local retinoid concentrations. Mice were treated orally and topically with synthetic ligands and bioimaging, QRT-PCR and retinoid analysis were performed. Topical application of the synthetic RAR ligand AM580 significantly enhanced retinoid signaling in skin while topical application of the RXR ligand LG268 did not influence retinoic acid receptor response elements (RARE)-mediated signaling. Systemic treatments with LG268 decreased the expression of genes involved in skin homeostasis, RA synthesis and skin RA concentrations, while it increased various markers for skin inflammation and RA degradation, which corresponds to decreased skin RARE signaling. We conclude from these observations that increased systemic concentrations of an RXR -ligand may be one reason for reduced retinoid signaling, -reduced all-trans RA levels in the skin, reduced epidermal homeostasis and increased skin inflammation marker expression with potential relevance for various skin disorders, like atopic dermatitis.
