Because the high expression of IL-17 in psoriasis may come from γδT cells, we detected IL-17A–producing γδT in lymph nodes of WT and K14-WFDC12 transgenic mice. There was no statistically significant difference in the proportion of IL-17A–producing γδT17 cells in lymph nodes in steady state (Figures S3E, F), but there was statistically significant difference in the proportion of IL-17A–producing γδT17 cells in lymph nodes after IMQ-induced psoriasis mice model (Figures 4F, G). This evidence concerns the gene IL17A and psoriasis.
