Mutations 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 کاملImmune 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 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...
متن کاملIntrafamilial transmission of hepatitis C virus.
Family members of hepatitis C virus (HCV)-infected hemodialysis patients had a high rate (8.1%) of HCV infection and were often infected by the same genotype of HCV as the renal patients. Renal patients who had a longer history of hemodialysis or more frequent arteriovenous shunt replacement posed a higher risk to their household contacts, especially to their primary-care providers at home.
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...
