Furthermore, whereas psoriasis-related genes, such as Cxcl2, Cxcl1, and Il1f6, were significantly induced in the skin of K14-IL17Aind Ctrl mice, the same genes were expressed neither in skin samples (Figure 5F) nor in keratinocytes isolated from mice harboring an additional deletion of IκBζ in keratinocytes (Figure 5G). The gene discussed is CXCL1; the disease is psoriasis.
