这种新型细胞的作用机制在于,将针对NKG2DL的CAR导入NK细胞后,CAR能够与癌细胞上表达的配体相结合,进而直接激活NK细胞,最终显著提升细胞的抗肿瘤免疫能力。 一项关于“应用NKG2D CAR-NK细胞治疗结直肠癌”的临床研究表明,CAR-NK细胞在控制...

将CAR-NK 细胞的应用范围,从血液肿瘤领域扩展到实体瘤领域。目前多项临床研究证实了CAR-NK细胞在治疗胰腺癌、胶质母细胞瘤、肺癌、乳腺癌、肝细胞癌、结直肠癌、卵巢癌等多款实体瘤方面均具有可行性。
Chimeric antigen receptor NK (CAR-NK) cell therapy is a gene engineering technology. It first transforms a fragment of scFv, an antibody capable of recognizing a specific tumor antigen and then integrates the fragment into the transmembrane chain segment
与CAR-T疗法类似,CAR-NK疗法最初也是被用来治疗各种血液恶性肿瘤,如白血病、骨髓瘤、淋巴瘤等。其中,BCMA(B细胞成熟抗原)、CD38、CD138是多发性骨髓瘤(MM)的常用靶点,此外,CD19、CD20和CD22是治疗白血病和B细胞淋巴瘤的常用靶点(详见下图)。图1 血液恶性肿瘤细胞治疗的热门靶点 ▲图源“Cell Death & ...
如果您对目前的治疗方案存疑,或想寻求CAR-NK、NK细胞等国内外新型抗癌疗法帮助,可联系医学部进行初步评估,或申请国内外抗癌专家会诊,以获得更大的生存获益!参考资料 [1]Pan K,et al.AR race to cancer immunotherapy: from CAR T, CAR NK to CAR macrophage therapy. J Exp Clin Cancer Res. 2022 Mar ...

2024年NK、CAR-NK、CAR-T、TIL、TCR-T五大细胞疗法疗效数据盘点,完全缓解率突破50%,通杀血癌及实体瘤,开启抗癌"私人定制"时代 癌症作为一种极其狡猾且复杂的疾病,它擅长伪装且会不断进化,因此,“联合疗法至关重要”,在现阶段,仅仅依靠单一的治疗手段往往难以达到预期的治疗效果。在早期精准诊断的基础之上,以...
通过基因改造使CAR-NK细胞表达IL-15,可以增强NK细胞的代谢能力,并提供更持久的抗肿瘤反应。此外,与单次输注相比,两次输注表达CAR-NK细胞可提高存活率。 参考文献: Li L, Mohanty V, Dou J, Huang Y, et al. Loss of metabolic fitness drives tumor resistance after CAR-NK cell therapy and can be over...
