The treatment of keratinocytes with this cytokine cocktail induced a strong psoriasis-like inflammatory response characterized by the production of inflammatory mediators IL-36γ, IL-8, and Chemokine (C-C motif) ligand 20 (CCL20) (Figure S1A) and a loss of the keratinocyte differentiation marker cytokeratin-10 in stratified RHEs (Figure S1B). This evidence concerns the gene CCL20 and psoriasis.
