| Abstract: | Objective To observe the cytotoxic T lymphocyte(CTL)induced with the DNA vaccine prepared by the co-expression of HIV-1CN gp 120 and IL-2 genes. Methods The plasmid pGPIL-2 for the coexpression of HW-1 Gag-gp 120 and IL-2 genes was transfected to BHK-21 cells under the mediation of liposome, and the expressed product was identified by indirect immumofluorescence method. Murine splenocytes were immunized with the pGPIL-2, and the CFL killing activity of the mice was detected. Results The CTL killing activity to the target cells transfected with HIV-1CN chimeric gene was effectively induced by pCPIL-2. Conclusion The study provides an important basis for further developing the DNA vaccine against the current HIV-1 strain in China. |
