Immunogenicity of dengue virus E antigen gene in BALB/c mice / 中国免疫学杂志

Objective:To study the possibility of dengue virus E gene vaccine.Methods:The recombinant eukaryotic expression plasmid pcDNA3 E was first transfected into NIH3T3 cells by lipofectin SDS PAGE and Western blotting analyzed the expression of E gene Then the recombinant plasmid was intramuscularly injected to BALB/c mice,and the specific humoral and cellular immunity were tested Results:The recombinant plasmid DNA could induce specific immune reactions and the immune response could last a long time Conclusion:The dengue virus E gene vaccine could induce specific immune reaction,which might have provided some material and new experimential data for the further study of dengue vaccines
