The evolutionary origin of human hepatitis delta virus (HDV) replication by RNA-directed transcription is unclear. Here we identify two species of 5'-capped, approximately 18-25-nucleotide small RNAs. One was of antigenomic polarity, corresponding to the 5' end of hepatitis delta antigen (HDAg)

Several viral transcriptional activators have been shown to interact with the basal transcription factor TATA-binding protein (TBP). These associations have been implicated in facilitating the assembly of the transcriptional preinitiation complex. We report here that the hepatitis B virus protein X

Seed-specific expression is an appealing alternative technology for the production of recombinant proteins in transgenic plants. Whereas attractive yields of recombinant proteins have been achieved by this method, little attention has been paid to the intracellular deposition and the quality of such

Production of high-value recombinant proteins in transgenic seeds is an attractive and economically feasible alternative to conventional systems based on mammalian cells and bacteria. In contrast to leaves, seeds allow high-level accumulation of recombinant proteins in a relatively small volume and

Human immunodeficiency virus (HIV-1) and hepatitis B virus (HBV) spread via similar transmission pathways, and infection by HBV occurs in up to 32% of HIV-1 cases. Here, we describe the successful expression of novel recombinant HIV-1/HBV virus-like particles (VLPs) in Nicotiana tabacum and
