这项研究引入了一种新型纳米酶,可触发协同性铁和,增强癌细胞免疫性. 这种方法,结合化疗和免疫疗法,通过重编程瘤微环境,有效地根除瘤.
科学领域:
- 生物医学工程 生物医学工程
- 纳米技术纳米技术
- 癌症研究 癌症研究
背景情况:
- 固体瘤通常由于免疫性较低和T细胞透率较低而抵抗免疫疗法,从而限制了免疫检查点阻塞 (ICB) 的有效性.
- 开发增强瘤免疫性策略对于改善免疫治疗结果至关重要.
研究的目的:
- 开发一种双离子位点单原子纳米酶 (dis-SAzyme),能够诱导协同性铁和,以增强抗癌免疫力.
- 为了评估多克索鲁比载的,癌细胞膜伪装的dis-SAzyme (dis-SAzyme-Dox@M) 与肝细胞癌治疗的ICB疗法相结合的疗效.
主要方法:
- 构建一个Fe3+/Cu2+双离子位点单原子纳米酶 (dis-SAzyme),具有对反应性氧物种 (ROS) 生成和抗氧化剂耗尽的催化活性.
- 伪装多克索鲁比载的disa-SAzyme与癌细胞膜进行向瘤传递.
- 研究dis-SAzyme-Dox@M对瘤相关的巨细胞,树突细胞和T细胞透的影响.
- 在肝细胞癌模型中评估dis-SAzyme-Dox@M与αPD-1结合的体内治疗疗效.
主要成果:
- Dis-SAzyme诱导了协同作用的铁和,增强了瘤免疫性.
- Dis-SAzyme-Dox@M在癌细胞和两极化瘤相关的巨细胞中选择性诱导铁亡/亡,使其转向抗瘤M1表型.
- 治疗增加了CD8+ T细胞的透,并减少了瘤微环境中的CD4+调节性T细胞.
- 对dis-SAzyme-Dox@M和αPD-1的联合治疗在体内实现了显著的瘤根除.
结论:
- 通过结合催化疗法,化疗和免疫调节,Dis-SAzyme-Dox@M代表了增强免疫疗法的有希望的策略.
- 这种方法为设计先进的纳米酶提供了一个新的视角,以克服固体瘤中免疫疗法耐药性的问题.
