Correlations between genetic polymorphism of IFN-λ family gene and HBV infection, virus replication and clearance / 生物工程学报

Hepatitis B virus (HBV) infection is one of the most serious public health problems. HBV infection could lead to hepatitis B, and even further develop into hepatic cirrhosis and hepatocellular carcinoma. Interferon lambda (IFN-λ) is a member of the interferon (IFN) family and an important cytokine for antiviral defense. There are four members in IFN-λ family, including IFN-λ1, IFN-λ2, IFN-λ3, and IFN-λ4. The genetic polymorphisms in the IFN-λ genes are associated with HBV replication and treatment response of HBV patients. In this review, we summarized the roles of genetic polymorphisms of the IFN-λ genes played in HBV infection, disease progression and treatment, with the aim to better understand their function. This review could serve as a reference for the HBV prevention and treatment of HBV patients, as well as for future clinical usage.

Function of the IL28B gene in Hepatitis B virus infection / 生物工程学报

Hepatitis B virus (HBV) that causes Hepatitis B with a high chronic rate, could lead to hepatic cirrhosis and hepatocellular carcinoma. The IL28B gene belongs to a new interferon family λ and its genetic polymorphisms are identified to be associated with treatment effect and viral clearance. The purpose of this review is to discuss the role of the IL28B gene in treatment response and viral clearance of HBV-infected individuals, and further to reveal the mechanisms. This review could provide a theoretical basis for personalized medicines of HBV patients.
