目的

制作成细胞因子缓释微粒原位瘤苗(CytoMPS-ISV),观测CytoMPS-ISV抗瘤作用及其免疫效应。

方法

C57BL/6J小鼠皮下移植性肝癌模型瘤内注射CytoMPS 3次制作CytoMPS-ISV,观察其抗肿瘤作用及小鼠生存率;流式细胞仪检测小鼠外周血淋巴细胞变化,免疫组化法检测肿瘤组织的CD4+、CD8+和NK1.1+细胞浸润情况,体外检测小鼠脾CTL和NK细胞的杀瘤活性,检测疫苗诱导脾CTL的抗体阻断作用。

结果

与PBS注射组和对照组相比,瘤内注射CytoMPS后肿瘤生长受到显著抑制(P<0.01)。瘤内注射CytoMPS组血液中及局部浸润的CD4+、CD8+和NK细胞明显高于PBS组和对照组(P<0.05);淋巴细胞杀伤试验结果显示瘤内注射CytoMPS组小鼠的脾CTL对靶细胞的杀伤率明显高于PBS组(P<0.01)和对照组(P<0.05);抗体阻断作用试验显示接种疫苗的小鼠脾CTL的杀瘤活性可被抗CD8+、抗MHC-I单克隆抗体所阻断,但不被抗CD4+、抗MHC-II单克隆抗体所阻断。

结论

CytoMPS-ISV可以显著抑制肿瘤生长,能明显增强机体的抗肿瘤免疫作用,其诱导的CTL杀瘤特性是由MHC-I限制的CD8+ T细胞所介导。

Objective

To prepare the CytoMPS-related in situ vaccine (CytoMPS-ISV) and observe its protective and therapeutic antitumor effects in treatment of mice hepatoma.

Methods

Three times of intratumoral injection of CytoMPS in C57BL/6J mice subcutaneous hepatoma were performed, and the tumor growth and mice survival rates were observed. The proportions of peripheral blood lymphocytes were detected by FACS. The killing efficacy of cytotoxic T lymphocytes(CTLs) derived from spleens of CytoMPS-ISV vaccinated mice was evaluated with and without antibody-blocking preparation. Extent of tumor-infiltrating CD4+、CD8+ and NK1.1+ cells were also detected with immunohistochemical stain(IHC).

Results

Compared with the control group, the tumor growth in CytoMPS-ISV group was significantly inhibited(P<0.01). Moreover, the proportions of CD4+, CD8+ T cell and natural killer cell (NK) in peripheral blood in CytoMPS-ISV group were significantly higher, so were those of tumor-infiltrating lymphocytes in CytoMPS group. Compared with those in the control groups, the cytotoxicities of splenic CTL in CytoMPS-ISV group were significantly enhanced, which could be blocked by anti-mouse MHC Class I and anti-mouse CD8 antibody, but not by anti-mouse MHC Class II and anti-mouse CD4 antibody.

Conclusion

CytoMPS-ISV can significantly inhibit tumor growth and induce anti-tumor immunity. The killing efficacy of CytoMPS-ISV-induced CTLs is related to CD8+ T cells restricted by MHC-I.
