The increased concentration of cytokines including IL-6, IL-18, and IFN-γ in ACD rats could be reversed by the FK administration, while IL-10 expressed the opposite result; the expression level of TLR4, pERK1/2, and NF-κB could be downregulated by the treatment with FK in the ACD rat. Here, IL10 is linked to granular corneal dystrophy type II.
