Consistent with our in vitro findings, the expression of CXCL10 and GBP5, as well as the combined expression z-scores of genes in the enriched MHC-class II and cytokine signaling pathways, were significantly lower in skin biopsies with higher EGF expression compared to those with lower EGF expression among individuals with psoriasis. This evidence concerns the gene CXCL10 and psoriasis.
