The cellular receptor for murine coronavirus mouse hepatitis virus (MHV)-A59 is a member of the carcinoembryonic antigen (CEA) family of glycoproteins in the immunoglobulin superfamily. We isolated a cDNA clone (MHVR1) encoding the MHV receptor. The sequence of this clone predicts a 424-amino-acid glycoprotein with four immunoglobulinlike domains, a(More)
Mouse hepatitis virus-A59 (MHV-A59), a murine coronavirus, can utilize as a cellular receptor MHVR, a murine glycoprotein in the biliary glycoprotein (BGP) subfamily of the carcinoembryonic antigen (CEA) family in the immunoglobulin superfamily (G.S. Dveksler, M. N. Pensiero, C. B. Cardellichio, R. K. Williams, G.-S. Jiang, K. V. Holmes, and C. W.(More)
Association of the Infectious Diseases Society of America. Guidelines for prevention and treatment of opportunistic infections in HIV-infected adults and adoles-A NTIRETROVIRAL THERAPY (ART) CAN SUPPRESS THE level of human immunodeficiency virus (HIV) vi-remia (or " viral load ") to undetectable levels in the plasma of a substantial proportion of(More)
We have designed a computer program which rapidly scans nucleic acid sequences to select all possible pairs of oligonucleotides suitable for use as primers to direct efficient DNA amplification by the polymerase chain reaction. This program is based on a set of rules which define in generic terms both the sequence composition of the primers and the(More)
Tumor necrosis factor (TNF) induces an antiviral state in various cell lines. This antiviral state is quite similar to that established by interferon (IFN), e.g., TNF treatment of HEp-2 cells induces 2',5'-oligoadenylate synthetase activity. Both antiviral activity and synthetase induction are greatly reduced when TNF treatment occurs in the presence of a(More)
PCR is a technology born of the modern molecular biology era. The enzyme used for PCR, Taq DNA polymerase, supplied with the 10x buffer, is purchased as a cloned product, and the nucleoside triphosphates are ultrapure, buffered, and available at a convenient concentration. Yet, with all of these commercially available starting materials, PCR still fails,(More)
Mouse hepatitis virus (MHV) strain A59 uses as cellular receptors members of the carcinoembryonic antigen family in the immunoglobulin superfamily. Recombinant receptor proteins with deletions of whole or partial immunoglobulin domains were used to identify the regions of receptor glycoprotein recognized by virus and by antireceptor monoclonal antibody CC1,(More)
Monocytes cultured 7 to 10 days in recombinant human macrophage CSF (MCSF) were greater than 400-fold more susceptible to HIV infection than an equal number of cells cultured in medium alone. Levels of reverse transcriptase activity and p24 Ag in culture fluids of monocytes treated with MCSF 1 wk before and continuously after HIV infection were(More)
Fluid shear stress can stimulate secretion of tissue plasminogen activator (tPA) by cultured human endothelial cells, while plasminogen activator inhibitor type-1 secretion remains unstimulated. To determine whether hemodynamically induced changes in tPA messenger RNA (mRNA) levels also occur, primary cultures from the same harvest of primary human(More)
The need to broaden research directed at answering fundamental questions in HIV vaccine discovery through laboratory, nonhuman primate (NHP), and clinical research has recently been emphasized. In addition, the importance of attracting and retaining young researchers, developing better NHP models, and more closely linking NHP and clinical research is being(More)
