【摘要】:多形性胶质母细胞瘤(glioblastoma multiforme,GBM)是恶性程度最高的脑胶质瘤,传统手术结合放、化疗疗效有限。嵌合抗原受体是由单一分子组成的抗原重组受体,重新定向T细胞的特异性和功能,由CD28或4-1BB构成的第二代CAR-T能识别抗原,完全活化T细胞并增强T细胞功能和持久性,是新兴GBM疗法的关注焦点。本文从CAR-T研究现状出发,主要介绍其发展历程和GBM相关的有效靶点,综述其理论基础,着重以白介素13受体α2、表皮生长因子受体变异Ⅶ、人表皮生长因子受体2和酪氨酸蛋白激酶受体A2这四种胶质瘤相关抗原为例,探讨靶点的结构、功能特性、前期研究和临床研究前景。选择性表达在GBM的白介素13受体α2在临床Ⅰ期治疗复发性GBM是安全有效的;表皮生长因子受体变异Ⅷ只存在于癌细胞和胶质母细胞瘤干细胞,与预后不良密切相关,正在进行Ⅰ、Ⅱ期临床试验;表皮生长因子受体2和酪氨酸蛋白激酶受体A也取得重大进展。这些特异性CAR-T可能成为治疗相应靶向阳性的GBM的重要免疫疗法。本文集中总结了目前CAR-T治疗GBM的应用价值及挑战。
[Abstract]:Glioblastoma multiforme GBM (glioblastoma multiforme GBM) is the most malignant glioma with limited curative effect of conventional surgery combined with radiotherapy and chemotherapy. Chimeric antigen receptor is a recombinant antigen receptor composed of a single molecule, which redirects the specificity and function of T cells. The second generation CAR-T composed of CD28 or 4-1BB can recognize antigens, activate T cells and enhance the function and persistence of T cells, which is the focus of new GBM therapy. This paper mainly introduces its development process and effective targets related to GBM, and summarizes its theoretical basis, focusing on interleukin-13 receptor 伪 _ 2, epidermal growth factor receptor variation 鈪,
