在这里,我们提出了一种用于产生和验证缺氧敏感的嵌合抗原受体 (CAR)-T 细胞的方案。该方案介绍了基于慢病毒的缺氧敏感 CAR-T 细胞的产生及其表征,包括缺氧依赖性 CAR 表达和选择性细胞毒性的验证。
我们的研究主要集中在癌症免疫疗法上,特别是基于 CAR T 细胞的免疫疗法。在过去的 10 年里,我们一直在探索新的策略,使 CAR T 细胞能够特异性地靶向肿瘤,同时最大限度地减少副作用,甚至完全没有副作用。人们一直在探索新的策略来提高基于 CAR T 细胞的免疫疗法的安全性和有效性,特别是通过靶向肿瘤微环境,例如缺氧条件的 CAR,如该方案所示。
有趣的是,最近的研究表明,缺氧条件下的 CAR T 不仅大大提高了安全性,还减少了 CAR T 耗竭并增强了实体瘤的疗效。缺氧是肿瘤微环境的一个特征。我们的研究旨在帮助癌症免疫治疗领域的研究人员了解缺氧敏感的 CAR T 细胞的概念、它们的构建以及如何建立缺氧模型进行评估。
