在转移性泌尿生殖系统癌中,CTC+/PD-L1+患者以及CD4和CD8 T细胞计数较低与总生存期较短相关。CTC和淋巴细胞之间的直接相互作用研究有限,但免疫检查点疗法已被证明对实体肿瘤治疗有效,尤其是与PD-L1表达相关。然而,需要更多的机制研究来深入了解这些相互作用。
相反,通过受体(如在 T 细胞中表达的 PD-1、CTLA-4、TIM-3 和 LAG3)与其各自在 APC 和其他微环境细胞中表达的配体之间的相互作用,共抑制信号转导会抑制 T 细胞激活。例如,PD-L1 或 PD-L2 与 PD-1 受体之间的相互作用会去磷酸化 T 细胞受体信号转导通路的主要组分,从而使 T 细胞中的 TCR 信号转导...

We believe that these chemokines lure placental immune cells towards erythroid cells so that erythroid cells can induce anergy in those immune cells via cell-bound ligands such as PD-L1, enzymes such as ARG1, and secreted factors such as TGF尾-1....
PD-1(+) CD8(+) T cells are exhausted in tumours and functional in draining lymph nodes of colorectal cancer patients. "14-0458 was used in Flow cytometry/Cell sorting to evaluate the role of PD-1-PD-L1 pathway in CD8(+) T-cell functions in tumour-draining lymph nodes (TDLNs) and ...
Moreover, the percentage of PD-L1+ or PD-L2+ erythroid cells is higher in the placenta than in the spleen of pregnant mice. However, fetal liver erythroid cells do not express PD-L1 or PD-L2. Blockade of PD-L1 restores immunoreactivity during pregnancy, which is expressed in increased ...
第二队列中,PD-L1表达水平>25%的患者才可入组,患者皆为EGFR/ALK阴性 第三队列中,入组的患者PD-L1表达都需>90%,患者皆为EGFR/ALK阴性 入组患者接受每两周一次的10mg/kg的度伐利尤单抗,直至出现疾病进展或者不耐受毒性反应。 03 研究结果 总体来说,在三...
接着,团队通过结构域交换实验发现,PD-1 的胞外结构域和胞内结构域在这一功能差异中都起到了关键作用。然后,作者将注意力转向了胞外结构域,利用生物层干涉法(biolayer interferometry)、共聚焦显微成像(confocal imaging)和全内反射荧光显微...
