    Author: Zhou Z, Zhang D, Ren H.
    Journal: Zhonghua Gan Zang Bing Za Zhi; 1999 Mar; 7(1):3-5. PubMed ID: 10366971.
    Abstract:
    OBJECTIVE: To investigate the effectiveness of recombined retrovirus vector in gene therapy. METHODS: The retroviral vector PLXSN-S was constructed and transferred into PA317 by means of electroporation, then HepG2, P815, and EL4 cells were infected with the pseudovirus produced from PA317. In the meantime the gene immunization of PLXSN-S was also studied. RESULTS: HBsAg was expressed variously in the eukaryotic cells mentioned above and successfully evoked antibody response and CTL response to HBsAg after gene immunization. CONCLUSION: Intramuscular DNA immunization represents an efficient technique for priming CTL and antibody response to HBsAg. PLXSN may be used as an effective vector to carry genes of interest to target cells and immunization with it's DNA vaccine might be clinically useful for gene therapy.
