Beschreibung:
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〉
