基于免疫检查点的阻断疗法是肿瘤治疗的重大变革。PD-1是应用最广泛的免疫检查点抑制剂靶点,在治疗黑色素瘤和非小细胞肺癌等肿瘤中获得较好的临床收益(详见BioArt报道:Nature背靠背 | IL-2和PD-1阻断协同治疗中干细胞样CD25+CD8+T细胞的...

单药的研究均未有明显效果,而与其他检查点抑制剂联合使用才有些受益(LAG-3+PD-1显著优于PD-1,暂不谈“协同”还是“辅助”)。 看起来LAG3更合适作为一个辅助靶点,目前获批上市的药物为百时美施贵宝(BMS)开发的LAG3+PD1(Relatimab/Nivolumab),联合其他靶点如PD-L1、CTLA-4、TIGIT、TIM3最高阶段也只到2期。
or reduced PD-L1 expression, suggesting that the activatingJAK2p.V617F mutation could confer sensitivity to both JAK inhibitors and anti-PD1 immunotherapy... SD Li,M Ma,H Li,... - 《Genome Medicine》 被引量: 4发表: 2017年 Inflammatory Microenvironment and Specific T Cells in Myeloproliferativ...
为了明确Tfr细胞的增殖和分化异质性,作者首先将无免疫障碍病患者的扁桃体样本中的Tfh(CD4+/CD25lo/PD1hi/CXCR5hi)、CD25hi Tfh(CD4+/CD25hi/PD1hi/CXCR5hi)、Tfr(CD4+/CD25hi/PD1dim/CXCR5 dim)和Treg(CD4+/CD25hi/PD1-/CXCR5-)细胞通过分选的方式进行富集(图1A)。一系列功能验证实验表明这种细胞富集方式不...
In general, the ratio of PD-1 + Treg/PD-1 + CD8>1 could be regarded as an independent predictor of prognosis in advanced gastric cancer patients. Moreover, PD-1 + Treg/PD-1 + CD8 < 1 and high expression of TLS could indicate better neoadjuvant therapy response ...
Medical management易由于治疗抵抗性增加而复发。免疫治疗可生成 immunological memory generation(免疫学记忆),从而克服该缺点。adoptive cell therapy (CAR T, TCR, TIL)将会在本文中被讨论。没有原癌基因驱动的病人通过阻断PD1/PDL1检查点也能取得良好疗效。疫苗联合ICI(免疫检查抑制剂)能实现很好治疗效果。
(TregII cells) are phenotypically closest to intratumoral Tregcells, including in their expression of CCR8. Analyses of T cell antigen receptor repertoires further support the hypothesis that intratumoral Tregcells may originate primarily from peripheral blood TregII cells. Moreover, the signaling ...
Moreover, TIL PD1+CD8+ T-cells from Prdm1fl/flFoxp3YFP-Cre mice expressed increased levels of Ki-67 compared to WT counterparts (Additional file 12e). Given the recent finding that PD-1 expression balance between Teff and Treg cells can predict the clinical efficacy of PD-1 blockade ...
2022年1月27日,日本国家癌症研究中心Hiroyoshi Nishikawa教授课题组在Cancer Cell上在线发表题为Lactic acid promotes PD-1 expression in regulatory T cells in highly glycolytic tumor microenvironments的研究论文,发现乳酸可在高度糖酵解的肿瘤...
