EGR1 increases the innervation density of epidermal sensory neurons via upregulation of ARTN in keratinocytes in atopic dermatitis

Atopic dermatitis (AD) is the chronic inflammatory skin disease accompanied with severe pruritus. To explore the roles of EGR1 in atopic dermatitis and the relationship between EGR1 and pruritus-scratching behavior, we used a atopic dermatitis-like mouse model driven by house dust mite (HDM) treatment in wild type and EGR1 KO mice, followed with RNA-sequencing analysis. Overall design: Comparative gene expression profiling analysis of RNA-seq data for skin tissue of Naïve-Egr1+/+ mice, HDM-challenged Egr1+/+, Naïve-Egr1-/-, and HDM-challenged Egr1-/-.
