- Abstract:
- Human skin equivalents emerged as novel tools inpreclinical dermatological research. It is being claimed that theymay bridge the translational gap between preclinical and clinicalresearch, yet only a few studies have investigated their suitabilityfor preclinical drug testing so far. Therefore, we investigated ifinflammatory skin equivalents, which emulate hallmarks of atopicdermatitis (AD), are suitable to assess the anti-inflammatory effectsof dexamethasone (DXM) in a cream formulation or loaded ontodendritic core-multishell nanoparticles. Topical DXM applicationresulted in significantly decreased expression of the proinflamma-tory cytokine TSLP, increased expression of the skin barrierprotein involucrin, and facilitated glucocorticoid receptor trans-location in a dose-dependent manner. Further, DXM treatmentinhibited gene expression of extracellular matrix components, potentially indicative of the known skin atrophy-inducing side effectsof glucocorticoids. Overall, we were able to successfully assess the anti-inflammatory effects of DXM and the superiority of thenanoparticle formulation. Nevertheless the identification of robust readout parameters proved challenging and requires careful studydesign.
