Furthermore, inflammatory cytokines relevant to psoriasis pathogenesis, including Il17a, Tnfa, and Il1b, as well as neutrophil‐attracting chemokines, such as Cxcl1 and Csf3, were significantly upregulated at the mRNA level in Fads2‐silenced skin lesions compared to controls (Figure 2I). Here, IL17A is linked to psoriasis.
