Herpes simplex virus type 1 (HSV-1) mutants defective for envelope glycoprotein C (gC) and gB are highly impaired in the ability to attach to cell surface heparan sulfate (HS) moieties of proteoglycans, the initial virus receptor. Here we report studies aimed at defining the HS binding element of HSV-1 (strain KOS) gB and determining whether this structure is functionally independent of gB's ro...
Molecular epidemiology of GB type C virus among individuals exposed to hepatitis C virus in Cameroon
GB vims-C (GBV-C)仇epatitis G vims (HGV) is a positive, single-strand RNA virus that has been classified in the family Flaviviridae. Interestlngly, GBVIC/HGV appears to have a truncated or absent core protein at the amino teminus of the polyprotein. GBV-C/HGV is transmitted parenterally and probably sexually. Most GBV-C作iGV infections appear to be asymptomatiC, persistent, and no correlation bet...
BACKGROUND GB virus C (GBV-C) is an apathogenic virus that inhibits human immunodeficiency virus (HIV) replication in vitro. Mother-to-child transmission (MTCT) of GBV-C has been observed in multiple small studies. Our study examined the rate and correlates of MTCT of GBV-C in a large cohort of GBV-C-HIV-coinfected pregnant women in Thailand. METHODS Maternal delivery plasma specimens from 24...
The present study aimed at standardizing a real-time quantitative polymerase chain reaction assay to evaluate the presence of GBV-C/HGV RNA. A "TaqMan" assay using primers and probe derived from the 5¢ NCR region was developed and validated. Two hundred and fifty-three plasma samples from HIV-infected women were tested for GBV-C viremia and antibody against the envelope protein 2. GBV-C RNA was...
The novel flavivirus GB virus C/hepatitis G virus (GBV-C/HGV) has been detected in approximately 2% of blood donors in the United States, and neutralizing antibody to the envelope protein (E2), a marker of previous infection with GBV-C/HGV, is present in approximately 9% of donors. The rate of GBV-C/HGV infection among American children is unknown. To determine whether viral infection might occ...
GB virus type C (GBV-C) is a human flavivirus that may cause persistent infection, although most infected individuals clear viremia and develop antibodies to the envelope glycoprotein E2. To study GBV-C E2 antigenicity and cell binding, murine anti-E2 monoclonal antibodies (MAbs) were evaluated to topologically map immunogenic sites on GBV-C E2 and for the ability to detect or block recombinant...
Liposomes have been used primarily as a model system for studying biological membranes. Numerous chemical, biochemical and biophysical methods have been used to elucidate the various aspects of the interaction between proteins or peptides and phospholipids. Having in mind the potential use of synthetic lipopeptides as antiviral therapies and aiming for a better understanding of the molecular in...
