嵌合抗原受体(CAR)T细胞疗法已成为治疗白血病和淋巴瘤的一种成功选择。这些令人鼓舞的结局凸显了将过继细胞疗法用于其他肿瘤适应证,尤其是实体瘤的潜力。然而,CAR-T 细胞治疗实体瘤尚未取得成功。与液体肿瘤不同,实体瘤会形成不利的肿瘤微环境(TME)。CAR-T 细胞必须迁移至TME,在其中存活并保持功能,才能清除肿瘤。但目前尚无通用的临床前模型,能够系统测试候选CAR及靶点在体内浸润并清除人实体瘤的能力。本文提供一套详细方案,用于在携带表达抗原的人实体瘤的免疫缺陷(NSG)小鼠中评估人CAR CD4+辅助性T细胞和CD8+细胞毒性T细胞。
Chimeric antigen receptor (CAR) T cell therapy has proven to be a successful treatment option for leukemias and lymphomas. These encouraging outcomes underscore the potential of adoptive cell therapy for other oncology applications, namely, solid tumors.
However, CAR T cells are yet to succeed in treating solid tumors. Unlike liquid tumors, solid tumors create a hostile tumor microenvironment (TME). CAR T cells must traffic to the TME, survive, and retain their function to eradicate the tumor. Nevertheless, there is no universal preclinical model to systematically test candidate CARs and CAR targets for their capacity to infiltrate and eliminate human solid tumors in vivo.
Here, we provide a detailed protocol to evaluate human CAR CD4 + helper T cells and CD8 + cytotoxic T cells in immunodeficient (NSG) mice bearing antigen-expressing human solid tumors.
