Visna lentiviruses have a natural tropism for cells of the macrophage lineage of sheep and goats, but virus replication in these cells in vivo is restricted so that only small quantities of virus are produced. One restricting factor suggested in previous studies is that virus replication is dependent on the maturity of the cells: the more mature the cell, the less restrictive the replication of the virus. Since monocytes in peripheral blood are precursors of macrophages, we investigated the effect of cell maturation on virus replication under limited control conditions in vitro by inoculating blood leukocytes with virus and retarding …

Two Transcription Products Of The Vesicular Stomatitis Virus Genome May Control L-Cell Protein Synthesis, David D. Dunigan, Jean M. Lucas-Lenard Feb 1983

When mouse L-cells are infected with vesicular stomatitis virus, there is a decrease in the rate of protein synthesis ranging from 20 to 85% of that in mock-infected cells. Vesicular stomatitis virus, irradiated with increasing doses of UV light, eventually loses this capacity to inhibit protein synthesis. The UV inactivation curve was biphasic, suggesting that transcription of two regions of the viral genome is necessary for the virus to become inactivated in this capacity. The first transcription product corresponded to about 373 nucleotides, and the second corresponded to about 42 nucleotides. Inhibition of transcription of the larger product by irradiating …

Head-to-head comparisons of conventional influenza vaccines with adenovirus (Ad) gene-based vaccines demonstrated that these viral vectors can mediate more potent protection against influenza virus infection in animal models. In most cases, Ad vaccines are engineered to be replication-defective (RD-Ad) vectors. In contrast, replication-competent Ad (RC-Ad) vaccines are markedly more potent but risk causing adenovirus diseases in vaccine recipients and health care workers. To harness antigen gene replication but avoid production of infectious virions, we developed “single-cycle” adenovirus (SC-Ad) vectors. Previous work demonstrated that SC-Ads amplify transgene expression 100-fold and produce markedly stronger and more persistent immune responses than RD-Ad vectors …
