Description:
Biological variability of human immunodeficiency virus type-1 (HIV-1) is involved in the pathogenesis of acquired immunodeficiency syndrome (AIDS). Syncytium-inducing (SI) HIV-1 variants emerge in 50 percent of infected individuals during infection, preceding accelerated CD4+ T cell loss and rapid progression to AIDS. The V1 to V2 and V3 region of the viral envelope glycoprotein gp120 contained the major determinants of SI capacity. The configuration of a hypervariable locus in the V2 domain appeared to be predictive for non-SI to SI phenotype conversion. Early prediction of HIV-1 phenotype evolution may be useful for clinical monitoring and treatment of asymptomatic infection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Groenink, M -- Fouchier, R A -- Broersen, S -- Baker, C H -- Koot, M -- van't Wout, A B -- Huisman, H G -- Miedema, F -- Tersmette, M -- Schuitemaker, H -- New York, N.Y. -- Science. 1993 Jun 4;260(5113):1513-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Clinical Viro-Immunology, Central Laboratory of the Netherlands Red Cross Blood Transfusion Service, Amsterdam.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8502996" target="_blank"〉PubMed〈/a〉
