All mice with oxazolone-induced dermatitis had a dramatic increase in IL-1β, IL-4, IL-6, IL-10, TNF-α, IFN-γ, IL-16, IL-17C, IL-17E, IL-17F, IL-21, IL-22, and MIP-3a, whereas the concentrations of IL-12p70, IL-2, IL-17A, and IL-23 were lower in dermatitis mice (Figure 3f,g). This evidence concerns the gene IL2 and dermatitis.
