However, PI3, another AMP, as well as CCL20, which is needed for the recruitment of CCR6+ Th17 cells, seem to be co-induced by IL22, IL17F and IL1B. Interestingly, the psoriasis-associated AMPs S100A8 and S100A9, are located far away from Th17 cytokines and epithelial-specific AMPs in the dendrogram. Here, IL17F is linked to psoriasis.
