Methods: The immune checkpoint PD-L1 was analyzed using qPCR, immunoblots, and immunofluorescence. Melanoma sensitivity towards T cells was investigated via cytotoxicity, cell viability, and IL-2 assays employing CTLL-2 cells. Results: Maltol was found to reduce melanin co...
PD－L1的受体为PD－1，其胞质区含有免疫受体酪氨酸抑制基序，为抑制性的受体。静止的T细胞不表达PD－1受体，T细胞活化后开始表达PD－1［2-3］。当PDL1与活化T细胞表面的PD－1结合后，可抑制活化T细胞的增殖并且诱导产生IL－10等免疫负向调控细胞因子，抑制过度的免疫应答，有利于维持机体的免疫自稳，防止自身...
However, only a subset of patients exhibit a durable response—i.e., only approximately 10–40% of patients treated with anti- Programmed cell death protein 1 (PD-1)/Programmed death-ligand 1 (PD-L1) antibody monotherapy exhibited a durable response; the remaining majority population received ...

Programmed death ligand 1 (PD-L1) expressed on tumor cell surfaces mediates tumor-induced immunoresistance by inhibiting PD1-expressing tumor-infiltrating T cells. Here, we explored whether a soluble form of PD1 (sPD1-Ig), which blocks PD-L1, could synergize with TERT-TR-regulated HSVtk to ...
Expression of Programmed Death-Ligand 1 (PD-L1) is also reduced, declining from 1.34 卤 0.23 ng/mg protein (n=5) to 0.50 卤 0.05 ng/mg protein (n=6) following ARSB treatment. Inverse to the effect on galectin-3, SHP2, the ubiquitous non-receptor tyrosine phosphatase (PTPN11), binds...
And with these changes, the mRNA expression levels of IL-12, IFN-纬, IL-2, IL-10, TNF-伪 and PD-L1 in tumor microenvironment and IL-12, IFN-纬, IL-2 in spleen were also significantly increased (P<0.05). Altogether, our results indicate that a sufficient amountN. caninumtachyzoites...
