P53基因产物是肿瘤免疫治疗的一个有吸引力的靶点。本研究旨在了解MVAp53疫苗在肿瘤患者体内诱导P53特异性细胞毒性T淋巴细胞体外扩增的潜力。结果表明,23例癌症患者中有14例出现P53特异性干扰素-γ的产生、脱颗粒、细胞增殖和P53高表达的肿瘤细胞株的裂解。这些实验表明,MVAp53刺激有可能诱导记忆T细胞库中P53特异性细胞毒T淋巴细胞的扩增。这些数据表明,MVAp53疫苗是癌症免疫治疗的理想候选疫苗。
The p53 gene product is an attractive target for tumor immunotherapy. The present study aims to understand the potential of MVAp53 vaccine to induce expansion of p53-specific cytotoxic T lymphocyte ex vivo in cancer patients. The result indicated that 14 of 23 cancer patients demonstrated p53-specific IFN-γ production, degranulation, cell proliferation, and lysis of p53 overexpressed human tumor cell lines. These experiments show that MVAp53 stimulation has the potential to induce the expansion of p53-specific cytotoxic T lymphocyte from the memory T cell repertoire. The data suggest that MVAp53 vaccine is an ideal candidate for cancer immunotherapy.
