该试验由两种基因工程细胞系:PD-1效应细胞(PD-1 Effector Cells),即稳定表达人PD-1受体和转录因子诱导的荧光素酶报告基因的Jurkat T细胞;PD-L1 aAPC/CHO-K1细胞(aAPC PDL1 CHO Cell Line),是一种稳定表达人PD-L1和一种以抗原非依赖方式激活同源TCR的细胞表面蛋白的CHO-K1细胞。 当两种细胞共培养时,PD-1/...
PD1 (hPD1) and mouse PD1 (mPD1), as well as in vitro solid phase-based ELISA assay and cellular-based assays involving human Jurkat T cells expressing human/mouse PD1 and/or PDL1, B cell epitopes/mimotopes of Nivolumab and an anti-mPD1 mAb (with a blocking capacity) were identified. ...
2022年1月14日,来自美国德克萨斯大学圣安东尼奥分校医学系的Tyler J. Curiel教授课题组在Nat RevCancer(IF: 60.7)杂志上发表题为“Programmed cell death 1 ligand 1 signals in cancer cells”的综述[1]。本文简要讨论了肿瘤细胞固有PD1信号和非肿瘤细胞固有PDL...
【文献精选——文献精读】Programmed cell death 1 ligand 1 signals in cancer cells(癌细胞中的程序性细胞死亡1配体1信号) 表面表达的PDL1信号传递到免疫细胞PD1以抑制抗肿瘤免疫的范例有助于开发有效和革命性的免疫疗法,使用抗体阻断这些细胞外部相互作用。最近发现的...
DNA损伤反应(DDR)通路的遗传改变是B细胞恶性肿瘤中化学免疫疗法(CIT)耐药的常见机制。之前已经表明,CIT的协同作用依赖于化疗引起的肿瘤细胞和巨噬细胞之间的分泌串扰。然而,恶性细胞中DNA损伤途径的改变如何在功能上影响CIT的复杂相互作用和结果仍有待阐明。近日,来自德国科隆大学医院的研究人员在Blood杂志上发表文章,报道...

cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as atezolizumab or durvalumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Adding iadademstat to either ...
from getting worse. Immunotherapy with monoclonal antibodies, such as durvalumab and monalizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Saruparib is a PARP inhibitor. PARP is a protein that helps repair ...
优选地,检测的方法如下:步骤a:对来自于非小细胞肺癌患者的外周血标本用所述滤膜进行过滤,以获得外周血循环肿瘤细胞;步骤b:对步骤a获得的滤膜进行固定;步骤c:对步骤b获得的滤膜进行原位检测,以确定PDL1表达情况。更优选地,在步骤c中,使用免疫荧光双标方法对所述滤膜进行原位检测。尤其优选地,如果在步骤c中检测到...
