Abstract:
OBJECTIVETo investigate the anti-tumor effect of dendritic cells (DC) pulsed with G422 glioblastomas RNA in mice bearing intracranially G422 glioblastomas.
METHODSDCs were pulsed in vitro with glioblastomas G422 cell RNA. The tumor-bearing mice were injected intratumorally or subcutaneously with pulsed DCs, PBS, non-pulsed DCs. The survival duration of mice was recorded. Serum levels of cytokine IFN-gamma, IL-2, IL-10, IL-4 were detected. Pathological examination was performed.
RESULTSThe survival duration of mice with DC-based vaccine increased significantly(P<0.01). The serum IFN-gamma level was increased (P<0.01) and IL-10 level was decreased (P<0.05) after treatment. Pathological examination showed necrotic tumor in the treatment mice.
CONCLUSIONDC vaccination can significantly increase survival duration of mice with intratumoral or subcutaneous administration of vaccines.
