T cells in the immune system protect the human body from infection by pathogens and clear mutant cells through specific recognition by T cell receptors (TCRs). Cancer immunotherapy, by relying on this basic recognition method, boosts the antitumor efficacy of T cells by unleashing the inhibition of immune checkpoints and expands adaptive immunity by facilitating the adoptive transfer of genetically engineered T cells. T cells genetically equipped with chimeric antigen receptors (CARs) or TCRs have shown remarkable effectiveness in treating some hematological malignancies, although the efficacy of engineered T cells in treating solid tumors is far from satisfactory. In this review, we summarize the development of genetically engineered T cells, outline the most recent studies investigating genetically engineered T cells for cancer immunotherapy, and discuss strategies for improving the performance of these T cells in fighting cancers.
免疫系统中的 T 细胞通过 T 细胞受体(TCRs)的特异性识别,保护人体免受病原体感染并清除突变细胞。癌症免疫疗法依赖于这种基本识别方法,通过释放免疫检查点的抑制作用和促进基因工程 T 细胞的过继转移来增强 T 细胞的抗肿瘤疗效。嵌合抗原受体(CARs)或 TCR 基因修饰的 T 细胞在治疗某些血液系统恶性肿瘤方面显示出显著的疗效,尽管基因工程 T 细胞在治疗实体瘤方面的疗效还远不能令人满意。在这篇综述中,我们总结了基因工程 T 细胞的发展,概述了最近关于基因工程 T 细胞用于癌症免疫治疗的研究,并讨论了提高这些 T 细胞抗癌性能的策略。
