Abstract
AIM: To probe into the possibility of dendritic cells (DC) in preventing solid carcinomas such as gastric cancer (GC).
METHODS: Immunotherapy was proformed by DC sensitized by mRNA of gastric cancer cells.
RESULTS: The indices such as the production rate of ascites of mice (75%), the metastasis rate of tumor (25%), the survival rate of animals (75%) and the average weight of tumor (2.04±0.33 g) showed that the condition of the mice treated by DC was better than that in the control group (P< 0.01). And the level of gene expression of IL-12, IFN and IL-18 in local tumor tissue was significantly raised (P < 0.01) and the amount of local CD4+ (0.71±0.25/m2) and CD8+ (0.67±0.22/m2) cells was increased (P < 0.05) and the cytotoxicity of TIL was remarkably enhanced.
CONCLUSION: DC transfected with mRNA isolated from mouse tumor cells may effectively control the growth of tumor and ameliorate the symptoms, suggesting that a certain therapeutic efficiency for mice carrying tumor can be realized.
