1568-DESynR:领域重组人工转录因子增强CAR-T功能

from 聊聊Sci

这篇文章介绍了科研人员开发的一种名为 DESynR 的高通量基因工程平台,该平台通过重新组合天然转录因子的不同功能域来合成非天然的新型基因。研究重点展示了合成的 AP-1 转录因子在增强 CAR T 细胞抗肿瘤功能方面显著优于自然进化的转录因子。实验数据表明,这些人工合成因子能诱导 T 细胞进入一种非天然的治疗优化状态,同时提升其细胞毒性、增殖能力和持久性。此外,这种设计方法在 ETS 和 FOX 蛋白家族中也得到了成功验证,证明了其广泛的适用性。研究揭示,合成因子通过与天然因子共享基因组结合位点,但以不同的方式调节基因表达,从而实现对免疫细胞功能的精准编程。综上所述,该研究为通过探索非进化基因序列来优化细胞疗法提供了全新的策略。References:Takacsi-Nagy O, Kasinathan S, Hartman A, et al.
