    DNA amplification for direct detection of HIV-1 in DNA of peripheral blood mononuclear cells (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-01-15
    Description: By means of a selective DNA amplification technique called polymerase chain reaction, proviral sequences of the human immunodeficiency virus (HIV-1) were identified directly in DNA isolated from peripheral blood mononuclear cells (PBMCs) of persons seropositive but not in DNA isolated from PBMCs of persons seronegative for the virus. Primer pairs from multiple regions of the HIV-1 genome were used to achieve maximum sensitivity of provirus detection. HIV-1 sequences were detected in 100% of DNA specimens from seropositive, homosexual men from whom the virus was isolated by coculture, but in none of the DNA specimens from a control group of seronegative, virus culture-negative persons. However, HIV-1 sequences were detected in 64% of DNA specimens from seropositive, virus culture-negative homosexual men. This method of DNA amplification made it possible to obtain results within 3 days, whereas virus isolation takes up to 3 to 4 weeks. The method may therefore be used to complement or replace virus isolation as a routine means of determining HIV-1 infection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ou, C Y -- Kwok, S -- Mitchell, S W -- Mack, D H -- Sninsky, J J -- Krebs, J W -- Feorino, P -- Warfield, D -- Schochetman, G -- New York, N.Y. -- Science. 1988 Jan 15;239(4837):295-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Infectious Diseases, Centers for Disease Control, Atlanta, GA 30333.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3336784" target="_blank"〉PubMed〈/a〉

    Human chromosome 12 is required for elevated HIV-1 expression in human-hamster hybrid cells (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-10-27
    Description: Host cell factors act together with regulatory genes of the human immunodeficiency virus (HIV) to control virus production. Human-Chinese hamster ovary hybrid cell clones were used to probe for human chromosomes involved in regulating HIV gene expression. DNA transfection experiments showed that 4 of 18 clones had high levels of HIV gene expression measured by both extracellular virus production and transactivation of the HIV long terminal repeat in the presence of the trans-activator (tat) gene. Karyotype analyses revealed a 94% concordance (17/18) between human chromosome 12 and HIV gene expression. Other chromosomes had an 11 to 72% concordance with virus production.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hart, C E -- Ou, C Y -- Galphin, J C -- Moore, J -- Bacheler, L T -- Wasmuth, J J -- Petteway, S R Jr -- Schochetman, G -- New York, N.Y. -- Science. 1989 Oct 27;246(4929):488-91.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centers for Disease Control, Atlanta, GA 30333.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2683071" target="_blank"〉PubMed〈/a〉

    Molecular epidemiology of HIV transmission in a dental practice (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-05-22
    Description: Human immunodeficiency virus type 1 (HIV-1) transmission from infected patients to health-care workers has been well documented, but transmission from an infected health-care worker to a patient has not been reported. After identification of an acquired immunodeficiency syndrome (AIDS) patient who had no known risk factors for HIV infection but who had undergone an invasive procedure performed by a dentist with AIDS, six other patients of this dentist were found to be HIV-infected. Molecular biologic studies were conducted to complement the epidemiologic investigation. Portions of the HIV proviral envelope gene from each of the seven patients, the dentist, and 35 HIV-infected persons from the local geographic area were amplified by polymerase chain reaction and sequenced. Three separate comparative genetic analyses--genetic distance measurements, phylogenetic tree analysis, and amino acid signature pattern analysis--showed that the viruses from the dentist and five dental patients were closely related. These data, together with the epidemiologic investigation, indicated that these patients became infected with HIV while receiving care from a dentist with AIDS.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ou, C Y -- Ciesielski, C A -- Myers, G -- Bandea, C I -- Luo, C C -- Korber, B T -- Mullins, J I -- Schochetman, G -- Berkelman, R L -- Economou, A N -- New York, N.Y. -- Science. 1992 May 22;256(5060):1165-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of HIV/AIDS, Centers for Disease Control, Atlanta, GA 30333.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1589796" target="_blank"〉PubMed〈/a〉

    No evidence of murine-like gammaretroviruses in CFS patients previously identified as XMRV-infected (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-06-02
    Description: Members of the gammaretroviruses--such as murine leukemia viruses (MLVs), most notably XMRV [xenotropic murine leukemia virus (X-MLV)-related virus--have been reported to be present in the blood of patients with chronic fatigue syndrome (CFS). We evaluated blood samples from 61 patients with CFS from a single clinical practice, 43 of whom had previously been identified as XMRV-positive. Our analysis included polymerase chain reaction and reverse transcription polymerase chain reaction procedures for detection of viral nucleic acids and assays for detection of infectious virus and virus-specific antibodies. We found no evidence of XMRV or other MLVs in these blood samples. In addition, we found that these gammaretroviruses were strongly (X-MLV) or partially (XMRV) susceptible to inactivation by sera from CFS patients and healthy controls, which suggested that establishment of a successful MLV infection in humans would be unlikely. Consistent with previous reports, we detected MLV sequences in commercial laboratory reagents. Our results indicate that previous evidence linking XMRV and MLVs to CFS is likely attributable to laboratory contamination.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Knox, Konstance -- Carrigan, Donald -- Simmons, Graham -- Teque, Fernando -- Zhou, Yanchen -- Hackett, John Jr -- Qiu, Xiaoxing -- Luk, Ka-Cheung -- Schochetman, Gerald -- Knox, Allyn -- Kogelnik, Andreas M -- Levy, Jay A -- New York, N.Y. -- Science. 2011 Jul 1;333(6038):94-7. doi: 10.1126/science.1204963.

    Viral epitopes and monoclonal antibodies: isolation of blocking antibodies that inhibit virus neutralization (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-07-24
    Description: The inability of pathogenic animal viruses to be completely neutralized by antibodies can lead to chronic viral infections in which infectious virus persists even in the presence of excess neutralizing antibody. A mechanism that results in this nonneutralized fraction of virus was defined by the topographical relationships of viral epitopes identified with monoclonal antibodies wherein monoclonal antibodies bind to virus and sterically block the binding of neutralizing antibodies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Massey, R J -- Schochetman, G -- N01-CO-75380/CO/NCI NIH HHS/ -- New York, N.Y. -- Science. 1981 Jul 24;213(4506):447-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6264601" target="_blank"〉PubMed〈/a〉
