In AIH group, serum galectin-9 levels weakly correlated with alanine aminotransferase levels or total bilirubin (TB) and strongly correlated with C-X-C motif chemokine 10 (CXCL10) and Mac-2 binding protein glycosylation isomer (M2BPGi) levels, but did not correlate with the histological grade of liver fibrosis.
We aimed to examine the relationship between circulating cytokines/chemokines and the Mac-2 binding protein glycosylation isomer (M2BPGi) levels in Japanese patients with autoimmune hepatitis (AIH).We investigated the relationship between circulating cytokines/chemokines and M2BPGi levels in Japanese patients with AIH.
In PBC, gene expression relating to structural constituents and contractions of muscle such as actin and myosin were enhanced, in contrast to the downregulation of genes relating to protein binding in AIH.
We hypothesized that, anti-CD200 inhibited the phosphorylation of SHIP1, the expression of T-bet, GATA3 and FoxP3 mRNA and CD4<sup>+</sup> T differentiation to protect the liver from autoimmune hepatitis.
Compared with HC, resistin levels were raised in AIH (P = 0.017) and PSC (P = 0.03); compared with NAFLD, levels were elevated in CD (P = 0.041), AIH (P < 0.001) and PSC (P < 0.001).
As we previously showed in cases with chronic hepatitis B or C, in situ hybridization in both AIH and PBC cases demonstrated the expression of IP-10 mRNA in hepatocytes around focal or lobular necrosis surrounded by infiltrating mononuclear cells, whereas IP-10 mRNA was not expressed in areas around the damaged bile ducts in PBC cases.
We measured serum sICAM-1 and IP-10 by ELISA and found the levels were significantly higher in AIH patients (n = 77) compared with chronic viral hepatitis C patients (n = 32).
This study showed that the direct and indirect effect of IL-37 on macrophages could reduce the hepatic TNF-α expression, and also modulate IL-1β/IL-12 and IL-10/IL-1Ra expression to suppress the hepatic IFN-γ expression, thus suppressing the development of T cell-dependent liver injury such as autoimmune hepatitis.
We observed significantly lower levels of albumin, higher levels of aminotransferases, bilirubin, INR, IgG, higher IAIHG score and more severe histological findings in A-AIH than in C-AIH.
This former group of patients on the basis of the histology has been subdivided in the "genuine" acute onset (83 pts) and acute "on chronic" onset (45 pts) At onset, clinical acute AIH showed significantly higher ALT, bilirubin and INR levels (p < 0.001 for all), lower albumin values (p = 0.001), similar IgG levels; Response to treatment was similar between the two groups.
Here, we have demonstrated that the pseudokinase mixed lineage kinase domain-like protein (MLKL), which plays a key role in the execution of receptor-interacting protein (RIP) kinase-dependent necroptosis, is upregulated and activated in human autoimmune hepatitis and in a murine model of inflammation-dependent hepatitis.
PD-L1 and PD-L2 expressions were well correlated with the level of IFN-gamma; however, relatively decreased induction for PD-L1 and PD-L2 by IFN-gamma was observed in AIH or PBC than in CHC.
This study showed that the direct and indirect effect of IL-37 on macrophages could reduce the hepatic TNF-α expression, and also modulate IL-1β/IL-12 and IL-10/IL-1Ra expression to suppress the hepatic IFN-γ expression, thus suppressing the development of T cell-dependent liver injury such as autoimmune hepatitis.
This study suggests that nicotine increases α7-nAChR-mediated cholinergic activity in KCs resulting in decrease of ConA-induced autoimmune hepatitis through inhibiting NF-κB signaling.
This indicated that tissue inhibitor of metalloproteinase-1 and interstitial collagenase expression in autoimmune chronic active hepatitis were also coordinately up-regulated.3.
We hypothesized that, anti-CD200 inhibited the phosphorylation of SHIP1, the expression of T-bet, GATA3 and FoxP3 mRNA and CD4<sup>+</sup> T differentiation to protect the liver from autoimmune hepatitis.
These finding indicate that O-GlcNAc glycosylation plays a critical role in the activation of Notch signaling, which could promote Treg differentiation in the liver to inhibit T cell infiltration and control disease development in autoimmune hepatitis.
