摘　　要：AIM:To estimate the effect of a therapeutic vaccine against pancreatic carcinoma based on dendritic cell(DC)vaccine modified with tumor lysate and Interleukin-18 gene.METHODS:The BALB/C mice model of pancreatic arcinoma was induced with DMBA,DCvaccine was construted through pulsed with tumor lysate and transfected by the recombinant adenoviral vector encoding IL-18gene.The immnotherapeutic effects of DC vaccine on mice with pancreatic carcinoma were assessed (divided intoD-IL18-Lysate group,DC-Lysate group,DC-IL18 group,DC group,PBSgroup).RESULTS:After vaccination of the DC vaccine,the concentration of IL-18and IFN-γwere 2161±439ng·L^-1and435±72ng·L^-1inDC-IL18-Lysate group and there was significant difference compared with other groups(P<0.01)After vaccination of the DCcvaccine,the transplanted tumors were observed on 30days inDC-Lysate groups.on 16daysinDC-IL18groups.on3days in control group,but mice remained tumor-free for at least50days in DC-IL18-Lysate group and there was significant difference between DC-IL18-Lysate group and other groups(P<0.01).The median survival exceeds62days in DC-IL18-Lysate group.But the medsian surival was 48.6days in DC-Lysate group,33days in DC-IL-18group,17days in PBSgroup.The survival period was obviously prolonged in DC-IL18-Lysate group than in other groups(P<0.05,P<0.01).The weight of pancreatic tumor was0.22±0.083ginDC-IL18-Lysate group,1.45±0.74ginDC-Lysate group,1.89±1.34gin DC-IL18group,3.0±1.6ginDCgroup,2.9±2.0ginPBSgroup and the weight of tumor obviously reduced in DC-IL-18-Lysate group than in other groups(P<0.05,P<0.01).CONCLUSION:DC vaccine modified with tumo lysate and Interleukin-18gene can induce a specific and effective immune response against pancreatic cancinoma,cell. 关键词：干扰素-18 肿瘤细胞添解物树突状细胞胰腺癌大鼠免疫治疗
