IFNG and autoimmune hepatitis: In AIH patients, intrahepatic sulfatide-reactive type II NKT cells showed a differing cytokine profile in comparison to healthy subjects: TNFα expression was significantly higher in AIH patients compared to healthy subjects (77.8% of intrahepatic type II NKT cells were TNFα+ in AIH patients vs. 61.25% in healthy subjects; p < 0.05; Figure 7A), and IFNγ expression was significantly lower (32.7% of intrahepatic type II NKT cells were IFNγ+ in AIH patients vs. 69% in healthy subjects; p < 0.05; Figure 7B).
