在胶质母细胞瘤中,嵌合抗原受体(CAR)T细胞的局部递送是一种合理的治疗策略,可作为静脉给药的替代方案,以避开血脑屏障的阻碍。在此,我们开发了一种纤维蛋白凝胶,可负载CAR-T 细胞并促进其逐渐释放。利用胶质母细胞瘤次全切除术模型,我们证明,与直接将CAR-T 细胞接种到肿瘤切除腔相比,基于纤维蛋白凝胶在手术腔内递送CAR-T 细胞能够实现更优的抗肿瘤活性。
Regional delivery of chimeric antigen receptor (CAR) T cells in glioblastoma represents a rational therapeutic approach as an alternative to intravenous administration to avoid the blood-brain barrier impediment.
Here, we developed a fibrin gel that accommodates CAR-T cell loading and promotes their gradual release. Using a model of subtotal glioblastoma resection, we demonstrated that the fibrin-based gel delivery of CAR-T cells within the surgical cavity enables superior antitumor activity compared to CAR-T cells directly inoculated into the tumor resection cavity.
