Pre-treatment of Interferon-α stimulates DHX58 to prevent hepatic ferroptosis

Project description:Characterized by lethal iron accumulation and lipid peroxidation, ferroptosis plays critical roles in liver injury, especially caused by ischemia/reperfusion (I/R) of hepatic inflow occlusion during liver operation. However, the lack of effective and safe clinical precautionary measure is still the main problem in preventing hepatic ferroptosis. Here, we found that the excessive production of reactive oxygen species could decrease the expression of Interferon (IFN)-stimulated gene DExH-box helicase 58 (DHX58) in hepatocytes, and then promote hepatic ferroptosis, while pre-treatment using IFN-α increased DHX58 expression and prevented ferroptosis during I/R injury. Mechanistically, DHX58 with RNA-binding activity could constitutively associate the mRNA of glutathione peroxidase 4 (GPX4), a crucial ferroptosis suppressor, and then recruit the m6A reader YT521-B homology domain containing 2 (YTHDC2) to promote the translation of Gpx4 mRNA in m6A-dependent manner, thus enhancing GPX4 protein level and preventing hepatic ferroptosis. Therefore, we provide mechanistic evidence for the IFN-stimulated DHX58 in promoting the translation of m6A-modified Gpx4 mRNA, and suggest the promising clinical potential of IFN-α pre-treatment in the prevention of hepatic ferroptosis.

Interferon alpha treatment stimulates interferon gamma expression in type I NKT cells and enhances their antiviral effect against hepatitis C virus.

Project description:Interferon (IFN) inhibits hepatitis C virus (HCV) replication through up-regulation of intrahepatic IFN-stimulated gene expression but also through activation of host immune cells. In the present study, we analyzed the immune cell-mediated antiviral effects of IFN-α using HCV-infected mice. Urokinase-type plasminogen activator (uPA)-severe combined immunodeficiency (SCID) mice with transplanted human hepatocytes were infected with genotype 1b HCV and injected with human peripheral blood mononuclear cells (PBMCs). IFN-α treatment following human PBMC transplantation resulted in a significant reduction in serum HCV RNA titers and a higher human CD45-positive mononuclear cell chimerism compared to mice without human PBMC transplantation. In mice with human PBMCs treated with IFN-α, serum concentrations of IFN-γ increased, and natural killer T (NKT) cells, especially type I NKT cells, produced IFN-γ. Mice in which IFN-γ signaling was blocked using antibody or in which transplanted PBMCs were depleted for type I NKT cells showed similar levels of anti-HCV effect compared with mice treated only with IFN-α. These results show that IFN-α stimulates IFN-γ expression in type 1 NKT cells and enhances the inhibition of HCV replication. We propose that type 1 NKT cells might represent a new therapeutic target for chronic hepatitis C patients.
