Abstract: ObjectiveTo investigate whether immune adjuvant can enhance the immunity of dendritic cell vaccine against murine breast cancer. Methods4 groups of mice with tumor are injected saline, immume adjuvant, dendritic cell (DC) vaccine and DC vaccine coupled with immune vaccine, respectively. Tumor volume and weight are measured 21 d later.ResultsThe tumor size in the DC vaccine coupled with immune vaccine group was significantly small compared with control group (P=0.001) and the DC vaccine group (P=0.047).ConclusionImmune adjuvant can enhance the immunity of dendritic cell vaccine against murine breast cancer.

Key words: dendritic cell, immune adjuvant, breast carcinoma
