To develop effective anti-lung cancer vaccines, we directly mixed mycobacterial heat shock protein 65 (MHSP65) and tumor cell lysate (TCL) from Lewis lung cancer cells in vitro and tested its efficacy on stimulating anti-tumor immunity. Our results showed that MHSP65-TCL immunization significantly inhibited the growth of lung cancer in mice and prolonged the survival of lung cancer bearing mice. In vivo and in vitro data suggest that MHSP65-TCL could induce specific CTL responses and non-specific immunity, both of which could contribute to the tumor inhibition. Thus, this report provides an easy approach to prepare an efficient TCL based tumor vaccine.
为了开发有效的肺癌疫苗,我们在体外直接混合分枝杆菌热休克蛋白 65(MHSP65)和来自 Lewis 肺癌细胞的肿瘤细胞裂解物(TCL),并测试其刺激抗肿瘤免疫的功效。我们的结果表明,MHSP65-TCL 免疫接种显著抑制了肺癌在小鼠中的生长,并延长了肺癌荷瘤小鼠的生存时间。体内和体外数据表明,MHSP65-TCL 可以诱导特异性 CTL 反应和非特异性免疫,两者都有助于肿瘤抑制。因此,本报告提供了一种制备高效 TCL 基础肿瘤疫苗的简便方法。
