Abstract:
To study the cellular immune response and the anti-tumor effects induced by intramuscular DNA immunization with HER2/neu extracellular domain gene. Methods: HER2/neu oncogene extracellular domain gene was isolated and inserted to pCDNA3 expression vector. The cellular immune response and its anti-tumor effects were analyzed after intramuscular DNA immunization. Results: A specific cytotoxic activity by spleen cells from HER2/neu ECD gene immunized mice was found in vitro. Tumor growth was inhibited after tumor challenge in vivo in immunized mice. Conclusion: Specific cellular immune response and anti-tumor effect were elicited by HER2/neu extracellular domain gene immunization.
