Monocytes are effectors of the inflammatory response to microbes. Human CD14(+) monocytes specialize in phagocytosis and production of reactive oxygen species and secrete inflammatory cytokines in response to a broad range of microbial cues. Here, we have characterized the functions of human monocytes that lack CD14 (CD14(dim)) and express CD16. CD14(dim)(More)
We have generated a recombinant Newcastle disease virus (NDV) that expresses the green fluorescence protein (GFP) in infected chicken embryo fibroblasts (CEFs). This virus is interferon (IFN) sensitive, and pretreatment of cells with chicken alpha/beta IFN (IFN-alpha/beta) completely blocks viral GFP expression. Prior transfection of plasmid DNA induces an(More)
Replication of the RNAs of influenza virus occurs in the nucleus of infected cells. The nucleoprotein (NP) has been shown to be important for the import of the viral RNA into the nucleus and has been proposed to contain at least three different nuclear localization signals (NLSs). Here, an import assay in digitonin-permeabilized cells was used to further(More)
It has been demonstrated that the V protein of Newcastle disease virus (NDV) functions as an alpha/beta interferon (IFN-alpha/beta) antagonist (M. S. Park, M. L. Shaw, J. Muñoz-Jordan, J. F. Cros, T. Nakaya, N. Bouvier, P. Palese, A. García-Sastre, and C. F. Basler, J. Virol. 77:1501-1511, 2003). We now show that the NDV V protein plays an important role in(More)

The mitogen-activated extracellular signal-regulated kinase (MEK) pathway is one of the best-characterized kinase cascades in cancer cell biology. It is triggered by either growth factors or activating mutations of major oncogenic proteins in this pathway, the most common being Ras and Raf. Deregulation of this pathway is frequently observed and plays a(More)
Naturally occurring strains of Newcastle disease virus (NDV) have shown oncolytic therapeutic efficacy in preclinical studies and are currently in clinical trials. Here, we have evaluated the possibility to enhance the cancer therapeutic potential of NDV by means of reverse genetics. Mice bearing s.c. implanted CT26 tumors were treated with intratumoral(More)
Severe acute respiratory syndrome (SARS) is caused by a novel coronavirus termed SARS-CoV. We and others have previously shown that the replication of SARS-CoV can be suppressed by exogenously added interferon (IFN), a cytokine which is normally synthesized by cells as a reaction to virus infection. Here, we demonstrate that SARS-CoV escapes IFN-mediated(More)
Respiratory syncytial virus (RSV) is a major cause of severe lower respiratory tract disease in infants and the elderly, but no safe and effective RSV vaccine is yet available. For reasons that are not well understood, RSV is only weakly immunogenic, and reinfection occurs throughout life. This has complicated the search for an effective live attenuated(More)
