PD-L1是该家族中的第三个成员,多种肿瘤细胞高表达PD-L1在诱导肿瘤特异性T细胞凋亡和免疫逃逸过程中发挥重要作用,NSCLC的Ⅰ期临床试验显示PD-L1阳性可能是PD-1/PD-L1抑制剂有效的潜在生物标志物,目前PD-1/PD-L1抑制剂单药或与化疗和靶向药物联合治疗已进入NSCLC的Ⅰ-Ⅲ期临床试验,PD-L1在NSCLC患者临床标准治疗...
近日,清华大学药学院唐海东课题组在《Nature Communications》杂志在线发表了题为《树突状细胞的PD-L1分子削弱T细胞活化并调控免疫检查点阻断治疗的应答》(PD-L1 on dendritic cells attenuates T cell activation and regulates response to immune checkpoint blockade)的研究论文,揭示了树突状细胞上PD-L1分子在T细胞活化...
1,CD4+T细胞上的PD-L1结合配体后激活STAT3信号,抑制Th1极化和Th17分化。PD-L1信号还会诱导CD8+T细胞中T-bet-IFN-γ-无反应性表型,与PD-1信号同样具有抑制作用。2,PD-L1 + T细胞通过PD-L1-PD-1轴抑制效应T细胞。即使在没有内源性PD-L1时也可以促进肿瘤发生,表达PD-L1的T细胞可以和邻近T细胞上的PD-1结合,...
PD-L1-Vax肿瘤疫苗技术原理 无论是T细胞还是B细胞，他们对抗原的识别都依赖一种特殊的细胞——树突细胞(dendritic cell）也称DC细胞。DC细胞具有极强的抗原吞噬和加工处理能力，在不断吞噬抗原的过程中分化成熟，成熟的DC细胞可以携带抗原信号并传递给T/B细胞，接受抗原信号的T细胞会活化出具有特异性抗原杀伤能力的CTL...
PD-1 instructs a tumor-suppressive metabolic program that restricts glycolysis and restrains AP-1 activity in T cell lymphoma. Nat Cancer. 2023 Oct;4(10):1508-1525. doi: 10.1038/s43018-023-00635-7. Epub 2023 Sep 18. PMID: 37723306; PMCID: PMC10597841....
什么是PD-1和PD-L1? PD-1(programmed cell death protein 1)是程序性死亡受体1,是活化的T细胞表达的免疫检查点受体,是一种重要的免疫抑制分子。PD-1通过向下调节免疫系统对人体细胞的反应,以及通过抑制T细胞炎症活动来调节免疫系统并促进自身耐受。这可以预防自身免疫疾病,但它也...
Programmed cell death protein 1 (PD-1) ligation delimits immunogenic responses in T cells. However, the consequences of programmed cell death 1 ligand 1 (PD-L1) ligation in T cells are uncertain. We found that T cell expression of PD-L1 in cancer was regulated by tumor antigen and sterile...
