基于嵌合抗原受体(CAR)的免疫疗法显示出治疗功效。然而,额外的遗传修饰对于增强CAR-T细胞的功效和安全性是必要的。例如,从CAR-T细胞产生抗肿瘤细胞因子可能会增强其肿瘤杀伤活性,但人们担心抗癌分子的组成型表达会引起全身性副作用。因此,重要的是将外源基因表达限制在肿瘤部位。在这项研究中,我们的目标是开发开关启动子,它将响应来自CAR的激活信号。我们制备了一个开关盒,其按两个SV 40 polyA、四个NFAT-RE、最小IL-2启动子、ZsGreen 1和BGH polyA序列的顺序排列。将编码开关盒的基因转移到CD 19靶向的CAR表达PBMC中。与CD 19阳性靶细胞共培养强烈诱导PBMC中的ZsGreen 1表达。
英文摘要
Chimeric antigen receptor (CAR)-based immunotherapy shows therapeutic efficacy. However additional genetic modification is necessary for enhancement of the efficacy and safety of CAR-T cells. For example, production of an antitumor cytokine from CAR-T cells can potentially enhance their tumor-killing activity, but there are concerns that constitutive expression of anticancer molecules will cause systemic side effects. Therefore, it is important that exogenous gene expression is confined to the tumor sites. In this study, we aimed at developing switch promoters that would respond to activation signals from a CAR. We prepared a switch cassette that was arranged in order of two SV40 polyAs, four NFAT-REs, a minimal IL-2 promoter, ZsGreen1, and a BGH polyA sequence. Genes encoding switch cassettes were transferred into CD19-targeted CAR-expressing PBMCs. ZsGreen1 expression in PBMCs was strongly induced by co-culture with CD19-positive target cells.
