虽然癌症的发生和进展可以通过细胞毒性 T 细胞控制,但众所周知,肿瘤特异性 CD8+T 细胞通过获得一组称为免疫检查点的抑制性受体而变得功能受损。其中,程序性死亡-1 (PD-1) 是最受认可的 T 细胞功能负调节因子之一。在非小细胞肺癌 (NSCLC) 中,表皮生长因子受体 (EGFR) 的异常激活已知会诱导 PD-L1 表达,进一步使用 EGFR 酪氨酸激酶抑制剂 (TKI) 吉非替尼治疗,可降低 NSCLC 上 PD-L1 的表达。鉴于经常观察到通过产生限制其疗效的二级位点突变而对吉非替尼治疗产生获得性耐药,了解激活 EGFR 信号传导在 NSCLC 中调节 PD-L1 的下游机制非常重要。在这项研究中,我们证明AKT-STAT3通路可能是调节EGFR活性异常的NSCLC表面PD-L1表达的潜在靶点,此外,抑制AKT或STAT3活性甚至可以下调吉非替尼耐药NSCLC中PD-L1的表达。这些结果强调了 AKT-STAT3 通路作为通过调节具有异常 EGFR 活性的癌细胞上的 PD-L1 表达来增强抗肿瘤免疫反应的有希望的靶标的重要性。
While cancer development and progression can be controlled by cytotoxic T cells, it is also known that tumor-specific CD8+T cells become functionally impaired by acquiring a group of inhibitory receptors known as immune checkpoints. Amongst those, programmed death-1 (PD-1) is one of the most recognized negative regulators of T cell function. In non-small lung cancers (NSCLCs), the aberrant activation of epidermal growth factor receptor (EGFR) is known to induce PD-L1 expression and further the treatment with gefitinib, a tyrosine kinase inhibitor (TKI) for EGFR, decrease the expression of PD-L1 on NSCLC. Given the acquired resistance to gefitinib treatment frequently observed by developing secondary-site mutations limiting its efficacy, it is important to understand the downstream mechanism of activated-EGFR signaling for regulating PD-L1 in NSCLC. In this study, we demonstrated that AKT-STAT3 pathway could be a potential target for regulating the surface expression of PD-L1 on NSCLCs with aberrant EGFR activity and, further, the inhibition of AKT or STAT3 activity could down-regulate the expression of PD-L1 even in gefitinib-resistant NSCLCs. These results highlight an importance of AKT-STAT3 pathway as a promising target for potentiating anti-tumor immune responses by regulating PD-L1 expression on cancer cells with aberrant EGFR activity.
