The APOBEC3 family of mammalian cytidine deaminases, including APOBEC3G (A3G), has been shown to function as innate antiviral factors against retroviruses and can also suppress the replication of the hepatitis B virus (HBV). The mechanism by which A3G inhibits HBV replication remains to be elucidated. In this study, we show that the inhibitory effect of APOBEC3 proteins on HBV replication was m...
OBJECTIVES To investigate the presence of hepatitis B virus (HBV) DNA and hepatitis C virus (HCV) RNA in HIV-infected patients initiating antiretroviral therapy in Cameroon. METHODS Baseline blood samples from 169 patients were tested retrospectively for hepatitis B surface antigens (HBsAg), anti-hepatitis B core (anti-HBc), anti-HCV and - if HBsAg or anti-HCV result was positive or indetermi...
Abstract: Viral hepatitis (Hepatitis B Virus (HBV) & Hepatitis C (HCV)) related liver disease is a leading cause of morbidity and mortality especially in the patients with advanced renal failure who are treated dialysis, this due to high number blood transfusion sessions and/or cross contamination from dialysis circuits. Aims Objectives: This study aimed determine prevalence HBV HCV infecti...
UNLABELLED We have previously shown that Toll-like receptor (TLR)-activated murine nonparenchymal liver cells [(NPC); Kupffer cells (KC), liver sinusoidal endothelial cells (LSEC)] can suppress hepatitis B virus (HBV) replication. Therefore, the aim of this study was to investigate whether HBV has the ability to counteract the TLR-mediated control of its replication. Freshly purified murine hep...
BACKGROUND Hepatitis B virus (HBV) and hepatitis C virus (HCV) co-infections contributes to a substantial proportion of liver disease worldwide. The aim of this study was to assess the clinical and virological features of HBV-HCV co-infection. METHODS Demographic data were collected for 3238 high-risk people from an HCV-endemic region in China. Laboratory tests included HCV antibody and HBV s...
Liver cancer in men is the second leading cause of cancer death and hepatocellular carcinoma (HCC) accounts for 70%-85% of the total liver cancer worldwide. Chronic infection with hepatitis B virus (HBV) is the major cause of HCC. Chronic, intermittently active inflammation provides "fertile field" for "mutation, selection, and adaptation" of HBV and the infected hepatocytes, a long-term evolut...
The Chemagic Viral DNA/RNA kit was evaluated for extraction of cytomegalovirus (CMV), hepatitis B virus (HBV), and hepatitis G virus (HGV) by using the QIAamp DNA Blood Mini kit and the QIAamp Viral RNA Mini kit as reference protocols. The extraction efficiencies of the different kits for CMV DNA and HBV DNA were not distinguishable, but the extraction efficiency for HGV RNA was better with the...
Hepatitis delta virus (HDV) is a defective RNA virus with similarities to unusual subviral pathogens of higher plants. It requires hepatitis B virus (HBV) for its replication/transmission, and HBV-infected humans are the only established host. HDV causes both severe acute hepatitis and rapidly progressive chronic disease in some individuals. The HDV life cycle involves remarkable features, such...
The C-terminal domain (CTD) of Hepatitis B virus (HBV) core protein is involved in regulating multiple stages of the HBV lifecycle. CTD phosphorylation correlates with pregenomic-RNA encapsidation during capsid assembly, reverse transcription, and viral transport, although the mechanisms remain unknown. In vitro, purified HBV core protein (Cp183) binds any RNA and assembles aggressively, indepe...
Background & Objectives: Hepatitis type G virus (HGV) is a flavivirus with RNA genome which has high nucleotide and amino acid similarity with HCV. HGV can infect blood lymphocytes for long period and may have role in inducing or complicating the clinical outcomes in patients with hematological malignancies. Therefore in this study the prevalence of HGV, HCV, and HBV infections were evaluated i...
