中文摘要

CAR-T 治疗血液恶性肿瘤临床成功显著,但实体瘤疗效受靶抗原异质性限制。为克服这一问题,研究者构建过表达LIGHT的CAR-T 细胞。LIGHT可结合癌细胞上的淋巴毒素β受体及免疫细胞上的疱疹病毒进入介质受体。此类细胞既能通过CAR依赖机制识别抗原,也能通过LIGHT与癌细胞受体相互作用产生抗原非依赖性杀伤;同时具有免疫刺激作用,可改善细胞增殖和细胞毒特征。结果提示LIGHT表达型CAR-T 可能清除抗原阴性肿瘤细胞,降低抗原阴性复发风险。

Chimeric antigen receptor (CAR) T-cell therapy has resulted in remarkable clinical success in the treatment of B-cell malignancies.

However, its clinical efficacy in solid tumors is limited, primarily by target antigen heterogeneity. To overcome antigen heterogeneity, we developed CAR T cells that overexpress LIGHT, a ligand of both lymphotoxin- receptor on cancer cells and herpes virus entry mediator on immune cells. LIGHT-expressing CAR T cells displayed both antigen-directed cytotoxicity mediated by the CAR and antigen-independent killing mediated through the interaction of LIGHT with lymphotoxin- receptor on cancer cells.

Moreover, CAR T cells expressing LIGHT had immunostimulatory properties that improved the cells' proliferation and cytolytic profile. These data indicate that LIGHT-expressing CAR T cells may provide a way to eliminate antigen-negative tumor cells to prevent antigen-negative disease relapse.
