ABSTRACT
Objective:
To construct DNA vaccines expressing prostate-specific membrane antigen(PSMA) and/or granulocyte-macrophage colony-stimulating factor(GM-CSF) and to determine their immunoactivity.Methods:
Recombinant plasmids pIRES-PSMA-mGM-CSF,pIRES-PSMA,and pIRES-mGM-CSF were constructed with DNA vaccine vector pIRES.After identified by endonuclease digestion,the above 3 plasmids and blank pIRES vector were used to immunize C56BL/6 mice(n=15).LDH release assay was used to exam the cytotoxicity of cytolytic T lymphocytes in each group.Results:
We successfully constructed the above mentioned recombinant plasmids.Mice in pIRES-PSMA-mGM-CSF immunized group had the highest specific cytotoxicity,followed by pIRES-PSMA and pIRES-mGM-CSF immunized groups.The blank pIRES group had the lowest cytotoxicity(P
