The results of Western blotting showed that the levels of STING, phospho‐TBK1/TBK1 (p‐TBK1/TBK1), phospho‐IRF3/IRF3 (p‐IRF3/IRF3), CXCL10 and inflammatory cytokines (IFN‐β, NF‐κB p65, TNF‐α, pro‐inflammatory cytokine interleukin‐1 beta [pro‐IL‐1β], IL‐17A and IL‐23) in the skin tissue of the mice were higher in the DM + IMQ group (Figure 3B,C). Here, TBK1 is linked to diabetes mellitus.
