OBJECTIVE: To clone and express the HIV-1B gp120 genes isolated at different organizations from a patient died of AIDS dementia complex (ADC) in eukaryotic cells.
METHODS: Using the genomic DNA isolated from peripheral lymphnodes, choroid plexus and occipital white matter from a patient died of ADC as the template, HIV-1B gp120 gene was amplified with PCR. After sequenced, HIV-1B gp120 was inserted into pcDNA3.1 (+) and recombinant expressing vector gp120/pcDNA3.1 (+) was constructed succeffuly confirming with sequencing. Then expressing vector was transfected into eukaryotic cells U87 using liposome transfection and expression of HIV-1B gp120 gene was assayed with indirect immunofluorescence.
RESULTS: HIV-1B gp120 genes isolated from peripheral lymphnodes, choroid plexus and occipital white matter of the ADC patient were successfully cloned and recombinant expressing vector gp120/pcDNA3; 1 (+) could express envelope glycoprotein HIV-1B gp120 in U87 cells.
CONCLUSION: All the HIV-1B gp120 gene isolated at the different organizations of the same ADC patient could express in U87 cells, which may supply a valuable basis for studying the neurotoxicity and neurotoxic mechanism of HIV-1 gp120 protein.
