In this Viewpoint, Fauci and colleagues from NIAID review the evidence underlying 2016 Prevention Access Campaign's "Undetectable = Untransmittable (U U)" HIV public health initiative, arguing that science now supports elimination of stigma associated with infection.

The cellular receptor for murine coronavirus mouse hepatitis virus (MHV)-A59 is a member of the carcinoembryonic antigen (CEA) family glycoproteins in immunoglobulin superfamily. We isolated cDNA clone (MHVR1) encoding MHV receptor. sequence this predicts 424-amino-acid glycoprotein with four immunoglobulinlike domains, transmembrane domain, and short intracytoplasmic tail, MHVR1 closely related to CEA-related mmCGM1 (Mus musculus gene member). Western blot (immunoblot) analysis performed...

Abstract Fluid shear stress can stimulate secretion of tissue plasminogen activator (tPA) by cultured human endothelial cells, while inhibitor type‐1 remains unstimulated. To determine whether hemodynamically induced changes in tPA messenger RNA (mRNA) levels also occur, primary cultures from the same harvst umbilical vein cells were either maintained stationary culture or exposed to arterial (25 dynes/cm 2 ) for 24 hours. Total cellular was isolated stressed and relative mRNA glyceraldehyde...

Abstract Cytokines are important mediators of effector lymphoid cell function during an immune response, but their expression in vivo response has not been well documented. We analyzed the kinetics cytokine gene course primary to goat antibody mouse IgD antibody. Total RNA was purified from spleens taken freshly killed BALB/c mice 1 7 days after immunization. The reverse transcriptase polymerase chain reaction used evaluate seven genes, all which encode cytokines that secreted by T cells and...

The need to broaden research directed at answering fundamental questions in HIV vaccine discovery through laboratory, nonhuman primate (NHP), and clinical has recently been emphasized. In addition, the importance of attracting retaining young researchers, developing better NHP models, more closely linking is being stressed. an era a level budget for biomedical U.S. National Institutes Health (NIH), HIV/AIDS efforts will be carefully prioritized such that resources energize can identified....

Mouse hepatitis virus-A59 (MHV-A59), a murine coronavirus, can utilize as cellular receptor MHVR, glycoprotein in the biliary (BGP) subfamily of carcinoembryonic antigen (CEA) family immunoglobulin superfamily (G.S. Dveksler, M. N. Pensiero, C. B. Cardellichio, R. K. Williams, G.-S. Jiang, V. Holmes, and W. Dieffenbach, J. Virol. 65:6881-6891, 1991). Several different BGP isoforms are expressed tissues mouse strains, we have explored which these glycoproteins serve functional receptors for...

As the third decade since AIDS was first recognized comes to an end, extraordinary advances have occurred in understanding, treatment, and prevention of HIV infection AIDS. a result these successes, it is now time focus on future challenges. Paramount among reaching goal truly controlling ultimately ending pandemic. To that researchers public health personnel worldwide are aggressively pursuing 3 key areas scientific research. Given availability highly effective therapeutic regimens for...

The primary pathophysiologic finding of the viral disease known as Korean hemorrhagic fever, etiological agent which is Hantaan virus (HTV), vascular instability. To investigate whether HTV was able to infect cells derived from human tissue and alter their behavior, we infected in vitro adult endothelial saphenous veins (HSVEC). We were detect presence antigens both by immunofluorescence Western blot (immunoblot) analysis early day 1 postinfection. HSVEC with produce infectious during first...

In this paper we report that macrophages can be stimulated to express detectable levels of IFN-γ-specific mRNA. Macrophages from lipopolysaccharide (LPS)-responsive, C3H/OuJ mice are induced by LPS increase steady-state mRNA, while those LPS-hyporesponsive C3H/HeJ not. This interstrain variation is apparently the result LPS-specific signal differences since derived both Lpsn and Lpsd mouse strains able produce comparable mRNA following stimulation with polyinosinic-polycytidylic acid. The...

Abstract Monocytes cultured 7 to 10 days in recombinant human macrophage CSF (MCSF) were greater than 400-fold more susceptible HIV infection an equal number of cells medium alone. Levels reverse transcriptase activity and p24 Ag culture fluids monocytes treated with MCSF 1 wk before continuously after significantly those control without MCSF. HIV-induced cytopathic effects the MCSF-treated cultures also increased both frequency extent. At any given viral inoculum, HIV-infected cells, level...

Interferon alpha (IFN-alpha) induces significant antiretroviral activities that affect the ability of human immunodeficiency virus (HIV) to infect and replicate in its principal target cells, CD4+ T cells macrophages. A major endogenous source IFN-alpha during any infection is macrophage. Thus, macrophages have potential produce both HIV. In this study, we examined production other cytokines by macrophage colony-stimulating factor (M-CSF)-treated cultured monocytes HIV infection. Tumor...

In a survey of 15 different virus isolates, no IFN-alpha or IFN-beta activity was detected in culture fluids HIV-infected T cells monocytes. Exogenous rIFN-alpha added to lymphoblast monocyte cultures induced restriction replication the amphotropic HIV that infect both cell types. With IFN-treated cells, levels reverse transcriptase (RT) were half those control cultures, but frequency infected p24 Ag released unchanged. contrast modest effect IFN on IFN-induced antiviral monocytes quite...

Mouse hepatitis virus (MHV) strain A59 uses as cellular receptors members of the carcinoembryonic antigen family in immunoglobulin superfamily. Recombinant receptor proteins with deletions whole or partial domains were used to identify regions glycoprotein recognized by and antireceptor monoclonal antibody CC1, which blocks infection murine cells. Monoclonal CC1 MHV-A59 virions bound only recombinant containing entire first domain MHV receptor. To determine could serve functional receptors,...

Tumor necrosis factor (TNF) induces an antiviral state in various cell lines. This is quite similar to that established by interferon (IFN), e.g., TNF treatment of HEp-2 cells 2',5'-oligoadenylate synthetase activity. Both activity and induction are greatly reduced when occurs the presence a beta subtype 1 (IFN-beta 1)-neutralizing antiserum. However, no one has yet directly demonstrated IFN-beta induction, either as supernatants from TNF-treated or IFN-specific mRNA Northern (RNA) blot...

In July 2010, the Obama Administration released a National HIV/AIDS Strategy for United States to refocus national attention on responding domestic HIV epidemic. The goals of strategy are reduce incidence; increase access care and optimize health outcomes among people living with HIV; HIV-related disparities. identifies small number action steps that will align efforts across federal, state, local, tribal levels government, maximally impact this article, we outline key programmatic research...
