There was an increase in the incidence of progression events with rises in HIV-1 RNA level > 5000 copies/ml and reductions in CD4 cell count under 200 x 10(6) cells/l. The events occurring with HIV-1 RNA < 5000 copies/ml were generally atypical.

Comparative RNA quantification of HIV-1 Group M and non-M with the Roche Cobas AmpliPrep/Cobas TaqMan HIV-1 v2.0 and Abbott Real-Time HIV-1 PCR

Prior to 1986, this was called human T-lymphotropic virus type III/lymphadenopathy-associated virus (HTLV-III/LAV). 2008-05-01 · Modulating HIV-1 RNA processing and utilization. McLaren M(1), Marsh K, Cochrane A. Author information: (1)Department of Molecular Genetics, University of Toronto, Toronto, Ontario. Expression of the integrated HIV-1 provirus is achieved by overcoming multiple barriers to the processing, transport and utilization of the viral RNA. HIV-1 RNA in the plasma of patients without antibodies to HIV-1 is indicative of acute or primary HIV-1 infection. The APTIMA HIV-1 RNA Qualitative Assay may also be used as an additional test, when it is reactive, to confirm HIV-1 infection in an individual whose specimen is repeatedly reactive for HIV-1 antibodies. RNA in the plasma of patients without antibodies to HIV-1 is indicative of acute or primary HIV-1 infection. The APTIMA HIV-1 RNA Qualitative Assay may also be used as an The major viral components of HIV-1 virions are full-length RNA (HIV-1 RNA) and its translation products.

Upon multivariate analysis, factors associated with detection of VLs between 20 and 49 copies/ml by the Cobas TaqMan HIV-1 v2.0 assay in an HIV clinic were the basal VL and time on antiretroviral therapy. HIV RNA AIDS RNA of HIV origin, a serum marker of a Pt's 'HIV-ness,' now the standard by which Pt response to antiretovirals is evaluated; HIV RNA levels correlate with CD4+ count, response to antiviral therapy, clinical stage and disease progression. HIV-1, the causative agent of acquired immunodeficiency syndrome (AIDS), contains an RNA genome that produces a chromosomally integrated DNA during the replicative cycle. Activation of HIV-1 gene expression by the transactivator Tat is dependent on an RNA regulatory element (TAR) located downstream of the transcription initiation site.

RNA-protein interactions are central fea-tures of many fundamental biological pro-cesses, including translation, mRNApro-cessing, and transcription. The HIV-1 Rev protein is an RNA-binding protein that regulates viral gene expression by affecting the relative amounts of spliced and un-spliced mRNAs that are exported to the cytoplasm.

It is roughly spherical with a diameter of about 120 nm, around 60 times smaller than a red blood cell. It is composed of two copies of positive-sense single-stranded RNA that codes for the virus's nine genes enclosed by a conical capsid composed of 2,000 copies of the viral protein p24.

Researchers claim that RNA tests are 99% effective, so there is no need to worry about the validity of the findings! This test detects human immunodeficiency virus type 1 (HIV-1) RNA from Group M, N and O subtypes; it does not detect HIV-1 proviral DNA. A result of "Not Detected" does not rule out HIV-1 RNA concentrations below the limit of detection of the assay or the presence of inhibitors in the patient specimen. For infants born to HIV-1-infected mothers, HIV-1 DNA or RNA tests are recommended at 0 to 2 days, 14 days, 1 to 2 months, and 4 to 6 months after birth. Two consecutive positive HIV-1 virologic test results (HIV-1 DNA and/or RNA) are necessary for confirming the diagnosis of HIV-1 infection in infants younger than 2 years of age. HIV-1 RNA contains m6A modifications that modulate viral infection and gene expression in CD4+ T cells. However, it remains unclear whether m6A modifications of HIV-1 RNA modulate innate immune responses in myeloid cells that are important for antiviral immunity. During HIV-1 assembly, the viral structural protein Gag recruits viral RNA (vRNA) to the plasma membrane (PM) from a pool of excess cellular RNAs.

Quantification of HIV-RNA (viral load measurements) can be used as a diagnostic test in certain situations; however, the HIV viral load is primarily used for management/monitoring of HIV-1-infected individuals. This topic will address the laboratory methods for quantitation of HIV-1 RNA and the use of viral load for clinical management.
