Megjegyzések:	Endogenous retinoids like all-trans retinoic acid (ATRA) play important roles in skin homeostasis and skin-based immuneresponses. Moreover, retinoid signaling was found to be dysregulated in various skin diseases. The present study usedtopical application of selective agonists and antagonists for retinoic acid receptors (RARs) a and c and retinoid-X receptors(RXRs) for two weeks on mouse skin in order to determine the role of retinoid receptor subtypes in the gene regulation inskin. We observed pronounced epidermal hyperproliferation upon application of ATRA and synthetic agonists for RARc andRXR. ATRA and the RARc agonist further increased retinoid target gene expression (Rbp1, Crabp2, Krt4, Cyp26a1, Cyp26b1)and the chemokines Ccl17 and Ccl22. In contrast, a RARa agonist strongly decreased the expression of ATRA-synthesisenzymes, of retinoid target genes, markers of skin homeostasis, and various cytokines in the skin, thereby markedlyresembling the expression profile induced by RXR and RAR antagonists. Our results indicate that RARa and RARc subtypespossess different roles in the skin and may be of relevance for the auto-regulation of endogenous retinoid signaling in skin.We suggest that dysregulated retinoid signaling in the skin mediated by RXR, RARa and/or RARc may promote skin-basedinflammation and dysregulation of skin barrier properties
