髓系抑制细胞(MDSCs)的聚集是实现合适的抗肿瘤免疫反应和成功治疗肿瘤的主要障碍之一。肿瘤宿主中的MDSCs主要是中性粒细胞(PMN-MDSCs)。然而,对MDSCs发育的调控机制仍然知之甚少。在这篇报道中,我们发现干扰素调节因子4(IRF4)在PMN-MDSCs的发展中起关键作用,而不是单核细胞MDSCs。IRF4缺乏导致PMN-MDSCs显著升高,增强了PMN-MDSCs的抑制活性,增加了肿瘤的生长和转移。机制研究表明,IRF4蛋白上调了c-Myc的表达。C-Myc的过表达几乎消除了IRF4缺失对PMN-MDSCs发育的影响。重要的是,在临床癌症患者中,IRF4的表达水平与PMN-MDSCs频率和肿瘤的发展呈负相关,而与c-Myc的表达呈正相关。综上所述,本研究表明,IRF4是一种新的肿瘤PMN-MDSCs发展调节因子,可能对肿瘤进展具有预测价值。
The accumulation of myeloid-derived suppressor cells (MDSCs) is one of the major obstacles to achieve an appropriate anti-tumor immune response and successful tumor immunotherapy. MDSCs in tumor-bearing hosts are primarily polymorphonuclear (PMN-MDSCs). However, the mechanisms regulating the development of MDSCs remain poorly understood. In this report, we showed that interferon regulatory factor 4 (IRF4) plays a key role in the development of PMN-MDSCs, but not monocytic MDSCs. IRF4 deficiency caused a significant elevation of PMN-MDSCs and enhanced the suppressive activity of PMN-MDSCs, increasing tumor growth and metastasis in mice. Mechanistic studies showed that c-Myc was up-regulated by the IRF4 protein. Over-expression of c-Myc almost abrogated the effects of IRF4 deletion on PMN-MDSCs development. Importantly, the IRF4 expression level was negatively correlated with the PMN-MDSCs frequency and tumor development but positively correlated with c-Myc expression in clinical cancer patients. In summary, this study demonstrated that IRF4 represents a novel regulator of PMN-MDSCs development in cancer, which may have predictive value for tumor progression.
