Abstract:
Objective:To investigate specific cellular immune response to the HPV16E7 prophylactic vaccine in mice.Methods:BALB/c mice were randomly divided into 3 groups:experimental group (treated with pcDNA3.1-HPV16E7),control group Ⅰ(treated with pcDNA3.1) and control group Ⅱ(treated with N.S.).Mice were injected (i.m.) pcDNA3.1-HPV16E7,pcDNA3.1 and N.S. one time per week,respectively.After three immunization,the blood samples from eye sockets and the supernatant cultured of spleen cells were taken for measurement IFN-? and the number of CD4 +?CD8 +T-lymphocyte by ELISA and FACS assay.Antigen-specific splenocyte proliferation assay in vitro was detected by MTT method.Results:The splenocytes actively proliferated,the number of CD4 +T lymphocyte and the quantitation of IFN-? in spleen and serum in the experimental group were significantly higher than the control group Ⅰ and Ⅱ.Conclusion:The pcDNA3.1-HPV16E7 DNA vaccine can induce specific cellular immune response in BALB/c mice.
