    Genomic structure of an attenuated quasi species of HIV-1 from a blood transfusion donor and recipients (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1995-11-10
    Description: A blood donor infected with human immunodeficiency virus-type 1 (HIV-1) and a cohort of six blood or blood product recipients infected from this donor remain free of HIV-1-related disease with stable and normal CD4 lymphocyte counts 10 to 14 years after infection. HIV-1 sequences from either virus isolates or patient peripheral blood mononuclear cells had similar deletions in the nef gene and in the region of overlap of nef and the U3 region of the long terminal repeat (LTR). Full-length sequencing of one isolate genome and amplification of selected HIV-1 genome regions from other cohort members revealed no other abnormalities of obvious functional significance. These data show that survival after HIV infection can be determined by the HIV genome and support the importance of nef or the U3 region of the LTR in determining the pathogenicity of HIV-1.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Deacon, N J -- Tsykin, A -- Solomon, A -- Smith, K -- Ludford-Menting, M -- Hooker, D J -- McPhee, D A -- Greenway, A L -- Ellett, A -- Chatfield, C -- Lawson, V A -- Crowe, S -- Maerz, A -- Sonza, S -- Learmont, J -- Sullivan, J S -- Cunningham, A -- Dwyer, D -- Dowton, D -- Mills, J -- New York, N.Y. -- Science. 1995 Nov 10;270(5238):988-91.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉AIDS Molecular Biology Unit, Macfarlane Burnet Centre for Medical Research, Fairfield, Victoria, Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7481804" target="_blank"〉PubMed〈/a〉

    Autologous red cell agglutination assay for HIV-1 antibodies: simplified test with whole blood (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-09-09
    Description: An antibody detection procedure based on agglutination of autologous red cells has been developed for samples of whole blood. A nonagglutinating monoclonal antibody to human red blood cells conjugated to a synthetic peptide antigen (in this case residues 579 to 601 of the HIV-1 envelope precursor, Arg-Ile-Leu-Ala-Val-Glu-Arg-Tyr-Leu-Lys-Asp-Gln-Gln-Leu-Leu-Gly-Ile-Trp- Gly-Cys - Ser-Gly-Lys) permitted the detection of antibodies to the human immunodeficiency virus type 1 (HIV-1) in 10 microliters of whole blood within 2 minutes. Agglutination was specifically inhibited by addition of synthetic peptide antigen but not by unrelated peptides. The frequency of false positive results was 0.1% with HIV-1 seronegative blood donors (n = 874). The false negative results were approximately 1% (n = 81). The autologous red cell agglutination test is potentially suitable for simple, rapid, qualitative screening for antibodies to a variety of antigens of medical and veterinary diagnostic significance.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kemp, B E -- Rylatt, D B -- Bundesen, P G -- Doherty, R R -- McPhee, D A -- Stapleton, D -- Cottis, L E -- Wilson, K -- John, M A -- Khan, J M -- New York, N.Y. -- Science. 1988 Sep 9;241(4871):1352-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, University of Melbourne, Repatriation General Hospital, Victoria, Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3413497" target="_blank"〉PubMed〈/a〉
