Abstract:

Overexpression of HER-2/neu oncogene is a frequent molecular event in multiple human cancer, including breast cancer (20%-40%), colorectal cancer (54%-100%), ovarian cancer (25%). Therefore, HER-2/neu protein is one of the candidate target antigens for cancer, and has been proved to have the potential to develop anti-breast cancer vaccines. At present, a series of studies have been carried out on different types of HER-2 vaccines, including whole-cell vaccines, full-sequence protein vaccines, peptide vaccines and DC-induced vaccines, and some progress has been made. A baidu Scholar, PubMed, Springer and ScienceDirect database search was performed to review the advanced of the preparation technology and the mechanism of antineoplastic activity of tumor vaccine based on HER-2/neu antigen. As the conclusions shown in the present paper, CD4+T and CD8+T were activated successfully and the anti-tumor specific immune response was induced by the antigen presenting cells (APCs) presented with the HER-2/neu tumor vaccine antigenic epitope. The immunological and anti-tumor activity would be improved by the change of vaccine design process, such as the reform of composition structure, fusion expression with immune-boosting short peptides and dendritic cell induced. The defect of drug resistance and repeated administration accompanied by HER-2 monoclonal antibody treatment and the serious toxicity of traditional chemotherapy drugs treatment could be reduced by HER-2 anti-tumor vaccine treatment with the stable anti-tumor activity in the clinic trail, which would provide a new perspective of tumor treatment.

Key words: HER-2/neu, tumor vaccine, dendritic cell, immune activity
