Of 13 different strains of hepatitis C virus (HCV) in the inoculum used, only 1 persisted in human lymphocyte cell lines infected in vitro (N. Nakajima, M. Hijikata, H. Yoshikura, and Y. K. Shimizu, J. Virol. 70:3325-3329, 1996). To determine whether that particular strain (designated H1-2) has a tropism for lymphocytes in vivo, we sequenced hypervariable region 1 (HVR1) of the genome of HCV re...
The possible role of candidate receptors in the cellular penetration of HCV from serum of infected patients remains unclear. SR-BI/Cla1 interacts with plasma HDL, native and modified LDL, and VLDL, and facilitates cellular cholesterol efflux to lipoprotein acceptors. SR-BI/Cla1 binds HCV E2 protein and interacts with HCV pseudotypes via the HVR1 of the E2 envelope glycoprotein. Our data reveal ...
Determining the origins of those buried within undocumented cemeteries is of incredible importance to historical archaeologists and, in many cases, the nearby communities. In the case of Avondale Burial Place, a cemetery in Bibb County, Georgia, in use from 1820 to 1950, all written documentation of those interred within it has been lost. Osteological and archaeological evidence alone could not...
Molecular characterization of early hepatitis C virus (HCV) infection remains rare. Ten out of 78 patients of a hematology/oncology center were found to be HCV RNA positive two to four months after hospitalization. Only two of the ten patients were anti-HCV positive. HCV hypervariable region 1 (HVR1) was amplified in seven patients (including one anti-HCV positive) and analyzed by next generati...
We describe an improved genetic immunization strategy for eliciting a full spectrum of anti-hepatitis C virus (HCV) envelope 2 (E2) glycoprotein responses in mammals through electrical gene transfer (EGT) of plasmid DNA into muscle fibers. Intramuscular injection of a plasmid encoding a cross-reactive hypervariable region 1 (HVR1) peptide mimic fused at the N terminus of the E2 ectodomain, foll...
Hepatitis C virus (HCV) persists in the majority of those infected despite host immune responses. Evidence has accrued that selectively fixed mutations in the envelope genes (E1 and E2) are associated with viral persistence, particularly those that occur within the first hypervariable region of E2 (HVR1). However, the individual amino acid residues under selection have not been identified, nor ...

Mitochondrial DNA (mtDNA) sequences have been retrieved so far from twelve Neandertal (Homo neanderthalensis) specimens: Feldhofer 1 and 2 in Germany [1,2], Mezmaiskaya in Russia [3], Monte Lessini in Italy [4], Vindija 75, 77 and 80 in Croatia [5,6], Engis 2 and Scladina in Belgium [6,7], La Chapelle-auxSaints and Rochers de Villeneuve in France [6,8] and Sidron 441 in Spain [9]. There are onl...
