Li et al. (Li et al., 2018) investigated the effects and mechanisms of ar-turmerone in a mouse model of imiquimod-induced psoriasis and concluded that ar-turmerone inhibited CD8+ T cell metastasis in the epidermis, decreased the expression of NF-κB, COX-2 and IL-6 levels, reduced the phosphorylation of p38MAPK, and downregulated the expression of IL-17, IL-22, and IL-23 mRNA. The gene discussed is IL6; the disease is psoriasis.
