摘要

针对实体瘤的适应性细胞疗法包括增强和再融合免疫细胞，以靶向肿瘤细胞。随着诱导多能干细胞技术的发展，T细胞和NK细胞等免疫细胞产品可用于ACT。然而，抑制性受体（如 TIGIT）的表达可能会限制这些免疫效应细胞的功能。在这项研究中，我们产生了一种同基因TIGIT基因敲除的iPSC细胞系，有可能防止抑制性信号传导和衰竭，从而为细胞免疫疗法应用创造出强效的 "现成 "免疫细胞产品。这种方法可以为抗击实体瘤提供一个新的领域。

Generation of a homozygous TIGIT gene knockout (TIGIT−/−) human iPSC line (MUSIi001-A-3) using CRISPR/Cas9 system

Adoptive cell therapy for solid cancers involves enhancing and reinfusing immune cells to target tumor cells. The advancement of induced pluripotent stem cell technology enables the generation of immune cell products like T and NK cells for ACT. However, the expression of inhibitory receptors, such as TIGIT, may limit the functionality of these immune effector cells. In this study, we generated a homozygous TIGIT gene knockout iPSC line to potentially prevent inhibitory signaling and exhaustion, thereby creating potent “off-the-shelf” immune cell products for cellular immunotherapy applications. This approach could offer a new frontier in the fight against solid tumors.
