Schematic presentation of the double-switch model of AD proposed by Domínguez-Hüttinger et al.5 The authors analyzed the literature and constructed a mathematical model with which they performed in silico experiments and assessed the dynamics of the skin and immune systems over time, testing innumerous conditions by changing model parameters. These investigations led to establishment of the double-switch model. The skin barrier defect allows microbial invasion of the epidermal layers, which activates pattern recognition receptors (PRR; depicted by yellow stars) in keratinocytes. This activation status is reversible (reversible switch). The activation of keratinocytes is conveyed to DCs, which promote the differentiation of naive T cells into TH2 cells. TH2 cell differentiation is considered irreversible in the model (irreversible switch). Differentiated TH2 cells further dysregulate keratinocyte functions.
