摘要
The human immunodeficiency virus （HIV） lentiviral vector is an ideal vector for gene therapy. In the present study, the wild-type HIV-1 genome was segregated into four plasmids, and an optimized novel HIV-1 lentiviral vector containing green fluorescent protein and vesicular stomatitis virus G pseudo-capsule was constructed. The plasmids were pHR-CMV-EGFP, pCMVΔ8.9, pRSV-Rev, pCMV-VSV-G. The four plasmid system was co-transfected into 293T cells, and green fluorescent protein expression was observed. The present study obtained lentiviral particles by high-speed centrifugation, and the lentiviral particle titer was 4 × 108 TU/mL after centrifugation. Thus, an optimized novel HIV-1 lentiviral vector was successfully constructed.
