Activation of the aryl hydrocarbon receptor dampens the severity of inflammatory skin conditions.

View SamplesEnvironmental stimuli are known to contribute to psoriasis pathogenesis and that of other autoimmune diseases, but the mechanism is unknown. Here we show that the aryl hydrocarbon receptor (AhR), a transcription factor that senses environmental stimuli, modulates pathology in psoriasis. AhR-activating ligands reduced inflammation in the lesional skin of psoriasis patients, whereas AhR antagonists upregulated inflammation. Similarly, AhR signaling via the endogenous FICZ ligand reduced the inflammatory response in the imiquimod-induced model of psoriasis and AhR deficient mice exhibited a substantial exacerbation of the disease, compared to AhR sufficient controls. Non-haematopoietic cells, in particular keratinocytes, were responsible for this hyper-inflammatory response, which involved increased reactivity to IL-1beta and upregulation of AP-1 family members of transcription factors. Thus, our data suggest a critical role for AhR in the regulation of inflammatory responses and open the possibility for novel therapeutic strategies in chronic inflammatory disorders. Overall design: Total RNA obtained from skin explants taken from psoriatic patients or healthy donors cultured in the presence of AhR agonist or antagonist

Specimen part
View SamplesDifferential gene expression was analyzed for FACS sorted Math1::Cre; ROSA-tdTomato from hand dissected cochlear nuclei of wild type and Hoxa2/Hoxb2 mutant mice Overall design: In order to investigate the role of Hoxa2 and Hoxb2 transcription factors in a subset of cells of the cochlear nucleus, we generated double conditional knock-out by crossing the deleter line Math1::Cre crossed with Rosa tdTomato; Hoxa2fl/fl; Hoxb2fl/fl and Rosa tdTomato wild type background. FACS sorted cells from hand dissected cochlear nuclei were than processed and RNA-seq performed (see extract protocol and library construction protocol).

View SamplesOxidative stress as a result of cigarette smoking is an important etiological factor in the pathogenesis of chronic obstructive pulmonary disease (COPD), a chronic steroid-insensitive inflammatory disease of the airways. The activity of the transcriptional co-repressor Histone deacetylase-2 (HDAC2) is dramatically reduced in COPD and cells exposed to oxidative stress or cigarette smoke. Moreover, curcumin (diferuloylmethane), a dietary polyphenol, at concentrations upto 1uM specifically restores cigarette smoke extract (CSE)- or oxidative stress- impaired HDAC2 activity. The aim of this study was to therefore identify any links through those gene sets that are affected by oxidative stress and subsequent treatment with curcumin in order to determine whether or not this could explain the impact of curcumin on restoration of oxidant impaired HDAC2 transcriptional co-repressor activity.
Curcumin restores corticosteroid function in monocytes exposed to oxidants by maintaining HDAC2.
