PD1 protein expression in TILs, but not PDL1 in tumor cells, was a favorable prognostic factor in TNBC. PD1/ PDL1 mRNA and protein expressions were inconsistent.doi:10.1080/15384047.2018.1423919Xinyu RenHuanwen WuJunliang LuYuhan ZhangZhiyong Liang...
GC patients with high level PDL1 expression in tumor cells or in immune cells were both associated with better survival compared with those with negative expression (5-year OS, 61% vs. 48%, P = 0.000, and 55% vs. 45%, P < 0.0001, respectively). As con... 展开 关键词: gastric ...
S4C). The superior functional fitness of circulating CD28- T cells may be ascribed to the reported CD28 inactivation occurring also at low PD1 densities, while TCR signaling is impacted mostly by PD1high expression [18]. We may also envision that in the tumor, a potentially higher PD1/PDL1 ...
Till we refine this further, PD-L1 expression (on tumor cells versus tumor infiltrating immune cells) may still be more of a prognostic marker with evolving predicting potential, but not necessarily something that would help guide selection of patients. If it has to be introduced into eligibility...
Programmed cell death 1 ligand 1 (PDL1) shows broad expression on both haematopoietic and non-haematopoietic cells, positioning the PD1 pathway as a key regulator of immune cell functions in both secondary lymphoid organs and in non-lymphoid tissues. PD1 limits the activation and function of poten...
Purposes:We previously demonstrated that Snail expression in tumor cells promotes bone metastasis not only by enhancing motility and bone polarity of tumor cells, but also by hindering anti-tumor immunity via increase of immunoregulatory... C Kudo-Saito,T Fuwa,K Murakami - 《Cancer Research》 被引...

抗PD1/PDL1治疗中,原发性耐药可能是肿瘤通过形成敌对的肿瘤微环境(Tumor microenvironment,TME)来阻碍T细胞的肿瘤清除过程,其耐药机制主要有: (a)高突变肿瘤更容易产生新的肿瘤抗原,减少抗原免疫原性,诱导肿瘤排斥反应; (b)B2M突变导致肿瘤抗原递呈失败; (c)原发性JAK1/2基因突变导致癌细胞对IFN-γ信号抵抗,抑制...

In ccRCC, PD-L1 expression is often upregulated, which correlates with poor prognosis and increased tumor aggressiveness. The engagement of PD1 by PD-L1 on tumor cells inhibits the anti-tumor immune response, allowing for unchecked tumor growth and progression [15]. Additionally, the tumor microen...
