Virus-specific cofactor requirement and chimeric hepatitis C virus/GB virus B nonstructural protein 3.
GB virus B (GBV-B) is closely related to hepatitis C virus (HCV) and causes acute hepatitis in tamarins (Saguinus species), making it an attractive surrogate virus for in vivo testing of anti-HCV inhibitors in a small monkey model. It has been reported that the nonstructural protein 3 (NS3) serine protease of GBV-B shares similar substrate specificity with its counterpart in HCV. Authentic prot...
متن کاملHepatitis C virus p7 and NS2 proteins are essential for production of infectious virus.
Hepatitis C virus (HCV) infection is a global health concern affecting an estimated 3% of the world's population. Recently, cell culture systems have been established, allowing recapitulation of the complete virus life cycle for the first time. Since the HCV proteins p7 and NS2 are not predicted to be major components of the virion, nor are they required for RNA replication, we investigated whe...
متن کاملThe Absence of Hepatitis C Virus Infection Among Patients with Hepatitis B virus in Mashhad, Iran
Background and Aims: Many studies have provided evidence for the role of hepatitis B and C viruses in the development of liver cancer. Although the routine treatment is available for both conditions, no definite guideline is available to treat patients dually infected with HBV and HCV. This study was performed to determine the frequency of HBV/HCV-coinfection in Mashhad, North-East of Iran. Mat...
متن کاملGB virus-C (hepatitis G virus) nostalgia.
The newly discovered human flavivirus identified as GB virus-C [1] and hepatitis G virus (HGV) [2], presents intriguing challenges in virology, epidemiology, and blood banking. Its clinical relevance for hepatology, however, appears to have been short-lived. Murthy and colleagues in this issue of Kidney International [3] provide additional evidence that the virus is not associated with clinical...
متن کاملFunctional analyses of GB virus B p13 protein: development of a recombinant GB virus B hepatitis virus with a p7 protein.
GB virus B (GBV-B), which infects tamarins, is the virus most closely related to hepatitis C virus (HCV). HCV has a protein (p7) that is believed to form an ion channel. It is critical for viability. In vitro studies suggest that GBV-B has an analogous but larger protein (p13). We found that substitutions of the -1 and/or -3 residues of the putative cleavage sites (amino acid 613/614 and 732/73...
