We report that CD39-expressing-melanoma cells inhibited both T-cell proliferation and the generation of cytotoxic effectors in an adenosine-dependent manner, and that treatment with a CD39-blocking antibody alleviated tumor-mediated immunosuppression. Thus, blocking CD39 ectonucleotidase may represent a novel immunotherapeutic strategy to restore antitumor immunity.
我们报告称,表达CD39的黑色素瘤细胞以腺苷依赖的方式抑制T细胞增殖和细胞毒性效应物的产生,并且用抗CD39阻断抗体治疗可减轻肿瘤介导的免疫抑制。因此,阻断CD39外核苷酸酶可能代表一种恢复抗肿瘤免疫力的新型免疫治疗策略。
