Abstract

Chimeric antigen receptor (CAR)-modified T (CAR-T) cell therapy has been proven to be a powerful tool for the treatment of cancer, however, the limits are obvious, especially for solid tumors. Therefore, constantly optimizing the structure of CAR to improve its therapeutic effect is necessary. In this study, we generated three different third-generation CARs targeting IL13Rα2, with the same scFv, but different transmembrane domains (TMDs) from CD4, CD8 or CD28 (IL13-CD4TM-28.BB.ζ, IL13-CD8TM-28.BB.ζ and IL13-CD28TM-28.BB.ζ). CARs were transduced into primary T cells using retroviruses. The anti-GBM efficacy of CAR-T cells was monitored by flow cytometry and real-time cell analysis (RTCA) in vitro and examined in two xenograft mouse models. The differentially expressed genes related to different anti-GBM activity were screened by high throughput RNA sequencing. We observed that T cells transduced with these three CARs have similar anti-tumor activity when co-cultured with U373 cells which expressed higher IL13Rα2 but exhibited different anti-tumor activity when co-cultured with U251 cells that expressed lower IL13Rα2. All the three groups of CAR-T cells can be activated by U373 cells, but only IL13-CD28TM-28.BB.ζ CAR-T cells could be activated and expressed increased IFN-γ after co-culturing with U251 cells. IL13-CD28TM-28.BB.ζ CAR-T cells exhibited the best anti-tumor activity in xenograft mouse models which can infiltrate into the tumors. The superior anti-tumor efficacy of IL13-CD28TM-28.BB.ζ CAR-T cells was partially owing to differentially expressed extracellular assembly, extracellular matrix, cell migration and adhesion-related genes which contribute to the lower activation threshold, increased cell proliferation, and elevated migration capacity.

摘要

嵌合抗原受体 (CAR)-修饰 T (CAR-T) 细胞疗法已被证明是治疗癌症的有力工具,然而,其局限性是显而易见的,尤其是对于实体瘤。因此,不断优化 CAR 的结构以提高其治疗效果是必要的。在这项研究中,我们生成了三种针对 IL13Rα2 的第三代 CAR,它们具有相同的 scFv,但来自 CD4、CD8 或 CD28 的跨膜结构域 (TMD) 不同 (IL13-CD4TM-28.BB.ζ、IL13-CD8TM-28.BB.ζ 和 IL13-CD28TM-28.BB.ζ)。CAR 通过逆转录病毒转导到原代 T 细胞中。通过流式细胞术和实时细胞分析 (RTCA) 在体外监测 CAR-T 细胞对 GBM 的疗效,并在两个异种移植小鼠模型中进行了检查。通过高通量 RNA 测序筛选与不同抗 GBM 活性相关的差异表达基因。我们观察到,当与表达更高 IL13Rα2 的 U373 细胞共培养时,转导这三种 CAR 的 T 细胞具有相似的抗肿瘤活性,但当与表达较低 IL13Rα2 的 U251 细胞共培养时,它们具有不同的抗肿瘤活性。所有三组 CAR-T 细胞都可以被 U373 细胞激活,但只有 IL13-CD28TM-28.BB.ζ CAR-T 细胞在与 U251 细胞共培养后可以被激活并表达增加的 IFN-γ。IL13-CD28TM-28.BB.ζ CAR-T 细胞在异种移植小鼠模型中表现出最佳的抗肿瘤活性,可浸润肿瘤。IL13-CD28TM-28.BB.ζ CAR-T 细胞的抗肿瘤疗效较好,部分原因是差异表达的细胞外组装、细胞外基质、细胞迁移和黏附相关基因,这些基因有助于降低激活阈值、增加细胞增殖和提高迁移能力。
