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 our study, we firstly identified a LUAD-specific circRNA, circRNA-002178 could act as sponge for miR-34a to relive the repression of miR-34a for PDL1 and promote PDL1 expression in tumor cells. Activated T cells were found to be high expressed several miRNAs19....

Cancer response to immunotherapy depends on the infiltration of CD8T cells and the presence of tumor-associated macrophages within tumors. Still, little is known about the determinants of these factors. We show that LIF assumes a crucial role in the regulation of CD8T cell tumor infiltration, ...
PD-L1 expression is associated with tumor FOXP3 (+) regulatory T-cell infiltration of breast cancer and poor prognosis of patient[J]. J Cancer, 2016, 7 (7) :784-793. Faraj SF, Munari E, Guner G, et al. Assessment of tumor infiltrating Iymphocytes as prognostic markers in resected ...
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 ...
Provided are antibodies that specifically bind to Programmed Death-1 (PD1, Pdcd-1, or CD279) and inhibit PD1-mediated cellular signaling and activities in immune cells, antibodies b
However, pharmacodynamics indicated a sustained mean occupancy of > 70% of PD-1 molecules on circulating T cells > or = 2 months following infusion, regardless of dose. In nine patients examined, tumor cell surface B7-H1 expression appeared to correlate with the likelihood of response to ...
