TNF and autoimmune hepatitis: ELISA analysis showed that concentrations of the inflammatory cytokines TNF-α, IFNγ, and IL-17 and the fibrotic cytokine TGF-β levels were significantly increased in the livers of AIH mice compared to the control group, while the anti-inflammatory cytokine IL-10 levels were significantly decreased (Figure 1(f); P < 0.05).
