这种差异导致了两种CAR T细胞在早期激活信号强度、细胞因子分泌、细胞毒性功能和持久性等方面的不同表现。 1.2.3 Mechanism of action(作用机制) CAR T细胞通过多种机制发挥抗肿瘤作用: 直接细胞毒性:CAR T细胞识别并结合靶细胞后,通过释放穿孔素和颗粒酶(如颗粒酶B)诱导靶细胞凋亡。此外,CAR T细胞还可以通过Fas-Fas...
一般基于药物作用机制(Mechanism of Action, MoA)选择Nab检测方法,但同时也要考虑方法学性能和药物免疫原性风险,采用符合目的的方式进行Nab方法学的选择。因此,对于CAR-T细胞的Nab检测,首先基于细胞的平台进行评价。可以是基于流式平台的Nab分析,也可以是基于MSD的细胞法Nab分析。 图2:基于细胞的Nab分析方法图示 如果...

The genetic alterations that are made to the T cells have been optimized to elicit a greater anti-tumor response. One of the genes that is inserted into the T cell is a portion of a T-cell receptor, called CD3ζ, linked to a module that targets a cancer cell. Additional costimulatory m...

Development and mechanism of action of CAR-T cells Chimeric antigen receptor (CAR) T cell therapy was developed using autologous peripheral blood to separate patients’ T cells, which are then engineered ex vivo to express synthetic receptors that can recognize TAAs. After the cells are expanded ...
Recently, clinical use of CAR-T cells for the treatment of relapsed, refractory hematological malignancies and multiple myeloma has achieved good results; at the same time, CAR-T cells can also be used to treat solid tumors. According to the different indications and mechanism of action of CAR...
Another mechanism is the use of transcriptional activation in response to recognition of user-specified antigens, using synthetic Notch (synNotch) receptors [42, 43]. This allows the activation of the CAR-T cells only in the context of the tumor. Other approaches include the inclusion in the ...
