这里所描述的治疗时间表旨在模拟护理临床标准，并充分利用其影响汽车继治疗。 CAR T细胞的剂量，TMZ治疗方案，和放射治疗施用可以被修改，以提高在体内的T细胞活性，淋巴细胞缺失，以及肿瘤杀伤。 TMZ治疗方案可以增加以得到主机myeloablation和过继转移的细胞30的膨胀增加。此外，TMZ的lymphodepletive效果可以通过低剂量被概括（4 - 6 Gy）进行单级分的全身照射（TBI），从而绕过SO...

胶质母细胞瘤（GBM）是最常见的原发性恶性脑肿瘤，并且总是致命的。手术切除加上护理化疗和放疗的非特异性标准未能完全消除恶性细胞，导致少于15个月的患者一预后不佳这种疾病1。与此相反，免疫治疗提供了一种精确的方法用于特异性靶向肿瘤细胞，并因此具有作为一个非常有效的治疗平台抵押品毒性2-4的风险降低的潜力。 T细胞工程体外表达嵌合抗原受体（车）提供了一个通用的策略肿瘤免疫治疗。通过融合的抗体的胞外可变区与一种或多种细胞内的T细胞信号传导分子（多个），以代替全长主要组织相容性复合体的生成的CARs体（MHC）-restricted T细胞受体5。的抗体样抗原recogniti此模式上允许反应活性的抗原特异性T细胞识别并在没有MHC的响应肿瘤抗原，并且可以适合于几乎无限抗原剧目。 设计对多种肿瘤抗原的CAR T细胞表现出临床前功效和卓越的承诺在门诊6-9。具体而言，在GBM的上下文中，一辆汽车的T细胞平台靶向表皮生长因子受体变体III（EGFRvIII的），肿瘤特异性突变在细胞表面上表达的10，被证明延长生存胶质瘤的小鼠11。尽管他们的通用性，然而，汽车过继疗法的临床效益尚未完全实现，在部分肿瘤相关的免疫抑制和免疫逃避12-16以及在建立和维持抗原特异性T细胞在体内的挑战所致。借力护理（SOC）的标准与免疫治疗可以潜在地克服这几条升仿制品，从而在两者的临床前和临床的设置增强的功效。 SOC进行后切除GBM由大剂量替莫唑胺（TMZ），一个DNA烷化剂17，和全脑照射（WBI）1。这些治疗方法都是通过推测肿瘤MHC表达18-20上调及抗原的死肿瘤细胞17,19,21,22脱落，以协同与肿瘤疫苗。实际上，在加入的TMZ 20,23或18,24的WBI导致在临床前设置免疫为主的治疗增强抗肿瘤功效。此外，像许多非特异性的细胞毒性化学治疗剂，TMZ是已知的导致全身性淋巴细胞25,26，其可以被利用作为宿主调节过继疗法平台27-29的一种手段。 TMZ介导的淋巴细胞缺失已显示增强抗原特异性T细胞的频率和功能，导致一个ADOP的增加的效力略去治疗平台对颅内肿瘤的30。在CAR疗法的上下文中，淋巴细胞缺失用作宿主调节的通过减少内源性抑制性T细胞31的数目，并通过减少竞争因子33诱导的稳态增殖32，从而提高抗肿瘤活性11,34的装置。定GBM SOC与免疫平台之间的协同关系，评价新颖代管疗法和疫苗平台在SOC的上下文是用于绘制关于功效有意义的结论是至关重要的。 在这个协议中，我们概述了鼠EGFRvIII的特异性CAR T细胞一起TMZ和WBI的生成和静脉内给药于小鼠的EGFRvIII阳性颅内肿瘤（参见图1进行治疗的时间表）的方法。简言之，将汽车的T细胞是由逆转录病毒转导所作体外 。人胚胎肾（HEK）293T细胞用DNA /脂质复合物（包含CAR载体和PCL-生态质粒），以产生病毒，然后将其用于转导被收获并在平行培养的活化鼠脾细胞进行转染。在汽车发生的过程中，轴承的EGFRvIII阳性颅内肿瘤的鼠宿主施用分馏全脑的X射线照射和全身TMZ治疗的剂量相当于临床SOC。 CAR的T细胞，然后静脉内递送至lymphodepleted主机。 下面的过程是在七个不同的阶段中描述：（1）管理的替莫唑胺对荷瘤小鼠，（2）全脑荷瘤小鼠的辐射;（3）转染，（4）脾切除和T细胞的制备，（5 ）转导，（6）CAR T细胞培养和收获，以及荷瘤小鼠（7）CAR T细胞管理。这些阶段包括跨越6-7天，并同时执行多个步骤。

generation of car t cells for adoptive therapy in the context of glioblastoma standard of care

Adoptive T cell immunotherapy offers a promising strategy for specifically targeting and eliminating malignant gliomas. T cells can be engineered ex vivo to express chimeric antigen receptors specific for glioma antigens (CAR T cells). The expansion and function of adoptively transferred CAR T cells can be potentiated by the lymphodepletive and tumoricidal effects of standard of care chemotherapy and radiotherapy. We describe a method for generating CAR T cells targeting EGFRvIII, a glioma-specific antigen, and evaluating their efficacy when combined with a murine model of glioblastoma standard of care. T cells are engineered by transduction with a retroviral vector containing the anti-EGFRvIII CAR gene. Tumor-bearing animals are subjected to host conditioning by a course of temozolomide and whole brain irradiation at dose regimens designed to model clinical standard of care. CAR T cells are then delivered intravenously to primed hosts. This method can be used to evaluate the antitumor efficacy of CAR T cells in the context of standard of care.
