Hepatitis C virus (HCV) displays high genetic diversity. Inter-host sequence variability may mainly reflect a neutral drift evolution. In contrast, intra-host evolution may be driven by an adaptive selection to host responses to infection. Here, HCV E2 intra-host evolution in two patients during the course and follow-up of successive treatments with(More)
Hypervariable region 1 (HVR1) of the hepatitis C virus (HCV) genome was directly sequenced from 12 chronically infected patients who had not responded to interferon (IFN) treatment. Due to the quasispecies nature of HCV circulating genomes, serum samples from four patients showing different evolutionary characteristics were further analysed. Serial samples(More)
The Autographa californica multiple nucleopolyhedrovirus (AcMNPV) ac109 core gene has been previously characterized as an essential late gene. Our results showed that budded virions could be detected in supernatants of infected Sf-9 cells, even when ac109 knockout viruses displayed a single-cell infection phenotype. Moreover, confocal microscopy analysis(More)
Baculoviruses are able to enter into mammalian cells, where they can express a transgene that is placed under an appropriate promoter, without producing infectious progeny. ORF109 encodes an essential baculovirus protein that participates in the interaction of the baculovirus with mammalian cells. To date, the mechanisms underlying this interaction are not(More)
