研究概要

早期联合治疗改变了细胞因子谱,增加了治疗动物血清中的干扰素-γ和肿瘤坏死因子-α,并下调了 CD8+ T 细胞中程序性细胞死亡蛋白 1 的表达。因此,树突状细胞与 NK 细胞之间的协同和认知相互作用,加之多柔比星治疗,促进了针对淋巴瘤的免疫反应和杀肿瘤活性。

研究思路结论见上方概要

肿瘤微环境中具有刺激作用的NK 细胞-树突状细胞轴可能在刺激细胞毒性T细胞和驱动抗癌免疫反应中发挥关键作用。

我们建立了一种新颖的治疗方案,巧妙地将多柔比星化疗与树突状细胞和NK 细胞的免疫疗法相结合,用于对抗一种高度侵袭性和恶性的淋巴瘤,称为道尔顿淋巴瘤。

我们的数据表明,过继性细胞疗法与化疗的二元联合应用几乎可治愈(95%)早期实验性淋巴瘤。对于中期癌症,成功率显著降低,但仍令人印象深刻(75%)。我们的结果表明,在早期癌症中应用联合疗法不仅显著缩小了肿瘤体积并延长了实验动物的寿命,还重新激活了免疫系统,包括恢复树突状细胞和NK 细胞的效应功能。这一新方案限制了肿瘤细胞在血管化器官中的转移,并重新武装了由树突状细胞以及 CD4 + 和 CD8 + T 细胞介导的适应性免疫应答。

We established a novel treatment protocol by adroitly combining chemotherapy with doxorubicin and immunotherapy with dendritic cells and natural killer cells against a highly aggressive and malignant lymphoma called Dalton's lymphoma.

Our data suggest that binary application of adoptive cell therapy and chemotherapy nearly cures (95%) early-stage experimental lymphoma. In the case of mid-stage cancer, the success rate was significantly lower but still impressive (75%). Our results demonstrated that the application of combination therapy in early-stage cancer significantly reduced the tumor volume and extended the lifespan of the experimental animal in addition to reinvigorating the immune system, including restoring the effector functions of dendritic cells and natural killer cells. The novel protocol limits the metastasis of tumor cells in vascularized organs and rearms the adaptive immune response mediated by dendritic cells and CD4 + and CD8 + T cells.

Combination therapy in the early stage alters the cytokine profile, increases interferon-γ and tumor necrosis factor-α in the serum of treated animals and downregulates programmed cell death protein 1 expression in CD8 + T cells. Thus, cooperative and cognitive interactions between dendritic cells and natural killer cells in addition to therapy with doxorubicin promote the immune response and tumoricidal activities against lymphoma.
