每天的时间决定癌症免疫疗法的反应
Wang等人的研究表明,肿瘤的免疫细胞浸润以及免疫细胞表型会以昼夜节律的方式摆动,可以利用这种方式优化癌症免疫疗法。在黑色素瘤小鼠模型中,肿瘤浸润白细胞(TILs)的数量在傍晚达到峰值,这是由于内皮细胞上的粘附分子ICAM-1水平波动所致。与早上相比,晚上用嵌合抗原受体(CAR)T细胞治疗能诱导肿瘤更大程度地缩小。此外,CD8+ T细胞上检查点分子PD1的表面表达在傍晚达到峰值,在黑色素瘤和结肠癌的小鼠模型中,使用PD1靶向抗体治疗在傍晚显示出效果,而在早晨则没有。在患有黑色素瘤的人类身上也发现了类似的TIL数量和表型的日时差异,尽管相位有所偏移,这也是昼伏夜出的人类与夜行性小鼠之间的差异。这些结果对免疫疗法时机的影响需要在未来的临床试验中进行检验。
