TNF and Wilson disease: Hepatic expression of cytokine genes increased in WD (IL1β; P = 0.0254 vs. Cont, IL10; P = 0.038 vs. Cont) and/or WD + Fe (TNFα; P = 0.0035 vs. Cont and P = 0.0028 vs. Fe, IFNγ; P = 0.0001 vs. Cont and P = 0.0001 vs. Fe, IL1β; P = 0.0047 vs. Cont, IL10; P = 0.0013 vs. Cont and P = 0.0026 vs. Fe) groups (Fig. 6c–f); expression of TNFα and IFNγ was higher in WD + Fe than in WD group (TNFα; P = 0.0352, IFNγ; P = 0.0004).
