For the anti‐inflammatory and anti‐proliferation property, lower levels of p‐STAT3, p‐Akt and PCNA were observed in IMQ+NB group (Figure 4K,L, quantification results in Figure S9H,I, Supporting Information) as well as mRNA levels of psoriasis‐associated cytokines (Il‐6, Il‐1α, Il‐1β, Il‐17A, Il‐17F, Il‐22, Il‐23, Tnfα) (Figure 4M). Here, IL17A is linked to psoriasis.
