title: Molecular cloning and in vitro evaluation of an infectious simian-human immunodeficiency virus containing env of a primary Chinese HIV-1 subtype C isolate.
abstract: Human immunodeficiency virus (HIV) clade C is the most prevalent subtype and accounts for approximately 50% of all HIV infections worldwide. In China, the prevalent HIV strains are B'/C subtypes, in which the envelope belongs to subtype C. To evaluate potential AIDS vaccines targeting Chinese viral strains in non-human primate models, we constructed an infectious simian-human immunodeficiency virus (SHIV) that expresses most of the envelope of a primary HIV strain, which was isolated from a HIV-positive intravenous drug user from XinJiang province in China. The resulting chimeric SHIV-XJ02170 was infectious in human, rhesus monkey and cynomolgus monkey peripheral blood mononuclear cells (PBMC) and used CCR5 exclusively as coreceptor.
