ABSTRACT
To explore the relationship between the genetic diversity and biological functional site of human immunodeficiency virus HIV-1 gp120 and the pathogenesis of AIDS dementia complex (ADC), the full length sequences of gp120 gene was amplified with PCR from genomic DNA which was extracted from lymphoid and different brain department (periaortic lymphoid, temporal gray/white matter junction, periventricular tissue, choroids plexus, occipital white matter and occipital gray/white matter junction.) of a patient who died of ADC. PCR products were cloned into the pGEM-T vector and positive clones were sequenced. The analysis of neighbor-joining tree, N-glycosylation sites, values of ds/dn, and loop were then all performed. The samples were all identified as HIV-1 B and genetic variation existed in HIV-1 gp120 isolated from different tissues. Compared with standard HIV-1B gp120, biological functional sites of HIV-1 gp120 isolated from the patient changed to some extent. In addition, there were differences in some biological functional sites of HIV-1 gp120 between lymphoid and brain. Therefore, genetic diversity and alterations of some biological functional sites of HIV-1 gp120 might be associated with the pathogenesis of ADC.
