白细胞介素-12(IL-12)是一种强有力的抗肿瘤细胞因子,可诱导和增强自然杀伤(NK)细胞、淋巴因子激活的杀伤(LAK)细胞和细胞毒性T淋巴细胞(CTL)的活性。IL-12还刺激T细胞和NK细胞产生IFN-γ。在这项研究中,我们用TNF基因转染甲基胆蒽诱导的纤维肉瘤(MCA-D),并在小鼠模型中研究TNF基因转导的癌症疫苗的治疗效果,以及全身给予重组IL-12(rIL-12)是否会增强疫苗的效果。TNF基因转导的癌疫苗或rIL-12的全身给药显示对预先建立的肿瘤的轻微或中度抑制。然而,同时应用疫苗和rIL-12导致完全根除。rIL-12与疫苗联合应用可增强CTL对亲代肿瘤细胞的杀伤作用,并协同增强脾细胞产生IFN-γ的能力。我们的研究结果表明,协同增强CTL活性和IFN-γ的产生可能在使用TNF基因转导的癌疫苗和rIL-12的联合治疗的抗肿瘤效果中起重要作用。
Interleukin-12 (IL-12) is a potent antitumor cytokine, which induces and enhances the activity of natural killer (NK) cells, lymphokine activated killer (LAK) cells and cytotoxic T lymphocytes (CTL). IL-12 also stimulates IFN-γ production from both T cells and NK cells. In this study, we transfected methylcholanthrene-induced fibrosarcoma (MCA-D) with TNF gene and investigated the therapeutic effect of TNF gene-transduced cancer vaccine and whether the vaccination effect is enhanced by systemic administration of recombinant IL-12 (rIL-12), in a murine model. TNF gene-transduced cancer vaccine or systemic administration of rIL-12 showed slight or moderate inhibition of pre-established tumor. However, simultaneous application of the vaccine and rIL-12 resulted in complete eradication. The cytotoxicity of CTL against parental tumor cells was enhanced with the combination of the vaccine and rIL-12, and IFN-γ production from spleen cells also increased synergistically. Our findings show that synergistic enhancement of CTL activity and IFN-γ production could play an important role in the antitumor effect of combination therapy using TNF gene-transduced cancer vaccine and rIL-12.
