description | Atopic dermatitis (AD) is the most common inflammatory skin disease. Stat3 mutation is a major cause of hyper IgE syndrome (HIES), which consistently represent AD like eczematous dermatitis. Based on multi-dimensional transcriptome analysis in pre- and post-flares skin, dermatitis phenotype was controlled by sequential two steps of Stat3 deficiency and environmental pathogenic stimuli. The Stat3 deficiency determined the barrier integrity that lowered threshold of inflammation, but this step was not sufficient to form pathogenicity. Transcriptome data indicated that emergence of dermatitis phenotype need to trigger robust activation of Nfkbia pathway and TH2 cells. Continuous colonization of Staphylococcus aureus was an environmental stimulus to lower the activation threshold of TH2 inflammation in the skin.
