P03 aims to identify oncogenic drivers of the protein CMTM6 – a stabilizer of PD-L1 surface expression – in leukaemia cells. Preliminary data show a link between oncogenic signalling, CMTM6 and PD-L1 in AML cells. P03 will decipher the downstream signalling events that promote CMTM6 and PD L1 expression in leukaemia cells. The effect of CMTM6 deficiency in leukaemia cells on T cell activation, metabolism and exhaustion and leukaemia immune escape will be studied in vitro and in immunocompetent murine AML models. P03 will clarify how oncogenic upregulation of the CMTM6/PD L1 axis contributes to leukaemia immune escape and whether CMTM6 blockade/deletion can enhance anti-leukaemia immune responses.

P03 旨在识别白血病细胞中蛋白质 CMTM6（一种 PD-L1 表面表达的稳定剂）的致癌驱动因素。初步数据显示，CMTM6 和 AML 细胞中的 PD-L1 之间的致癌驱动因素将破译下游信号事件。促进白血病细胞中 CMTM6 和 PD L1 的表达 白血病细胞中 CMTM6 缺乏对 T 细胞活化、代谢和耗竭的影响。白血病免疫逃逸将在免疫活性小鼠 AML 模型中进行体外研究，P03 将阐明 CMTM6/PD L1 轴的致癌性上调如何促进白血病免疫逃逸，以及 CMTM6 阻断/缺失是否可以增强抗白血病免疫反应。
