Immune tolerance split between hepatitis B virus precore and core proteins.
The function of the hepatitis B virus (HBV) precore or HBeAg is largely unknown because it is not required for viral assembly, infection, or replication. However, the HBeAg does appear to play a role in viral persistence. It has been suggested that the HBeAg may promote HBV chronicity by functioning as an immunoregulatory protein. As a model of chronic HBeAg exposure and to examine the toleroge...
متن کاملMutations in the Basal Core Promoter and Precore/Core Regions of Hepatitis B Virus in Patients Co-Infected With Human Immunodeficiency Virus
ABSTRACT Background and objectives: Globally, about one third of the population has been infected with Hepatitis B virus (HBV) and more than 400 million people have become chronically infected. Nearly, 20-25% of all carriers develop serious liver diseases such as cirrhosis, chronic hepatitis and hepatocellular carcinoma (HCC). According to t...
متن کاملMutations of Basal Core Promoter and Precore Regions in Hepatitis B Virus Genotypes B and C
BACKGROUND Mutations in basal core promoter (BCP) and precore regions of hepatitis B virus (HBV) are associated with course and treatment outcomes of chronic HBV infection. While BCP and precore mutation analysis have been carried out in adult patients between different genotypes, this analysis has rarely been performed for chronically infected children. OBJECTIVES The aim of this study was t...
متن کاملmutations of basal core promoter and precore regions in hepatitis b virus genotypes b and c
conclusions the mutation ratio difference between genotypes b and c in children was higher than that of adults and several combined mutations were exclusively detected in children with chronic hbv genotype c infection associated with higher viral load. objectives the aim of this study was to assess the mutation profiles of bcp and precore regions in different hbv genotypes in chronically infect...
متن کاملThe impact of hepatitis B virus precore/core gene carboxyl terminal mutations on viral biosynthesis and the host immune response.
BACKGROUND We aimed to elucidate the impact of hepatitis B virus (HBV) precore/core gene mutations on spontaneous hepatitis B e antigen (HBeAg) seroconversion, HBV biosynthesis, and the human immune responses in chronic HBV-infected patients. METHODS We analyzed the HBV precore/core gene sequences by cloning method in 33 chronic HBV-infected patients during the inflammatory phase before spo...
