中文摘要

尽管嵌合抗原受体(CAR)T细胞疗法治疗B细胞急性淋巴细胞白血病缓解率较高,但对毒性和疾病复发的担忧仍然存在。不同启动子可调节细胞表面CAR分子表达水平。本研究系统比较了4种不同启动子(MND、MSCV、EF-1和CMV)。结果显示,尽管这些启动子特征相近,MND启动子的病毒包装和转导效率更高。此外,MND启动子可增加参与细胞毒过程的初始T细胞比例,从而增强抗白血病疗效。

Although Chimeric antigen receptor (CAR) T cell therapy has demonstrated a high remission rate in B cell acute lymphoblastic leukaemia, concerns regarding toxicity and disease recurrence remain. Different promoters can modulate the expression levels of CAR molecules on the cell surface. In this study, we systematically compared four distinct promoters (MND, MSCV, EF-1 and CMV).

Our findings revealed that while these promoters exhibited similar characteristics, the MND promoter demonstrated superior viral packaging and transduction efficiency.

Furthermore, it enhanced the anti-leukaemia efficacy by increasing the proportion of na ve T cells involved in the cytotoxic process.
