IFNG transcripts were mostly expressed in lesional LP (median/section:4), IL13 (median/section:1.5) and IL17A (median/section:9) in AD and psoriasis, respectively, (Fig. 2n–p, Supplementary Fig. 3b) with an emphasized expression in upper skin layers (Fig. 3a, b, Supplementary Fig. 3a, c). This evidence concerns the gene IL17A and Alzheimer disease.
