Figure Lengend Snippet: A CRC cell lines were treated with the indicated concentrations of TER for 72 h. Cell viability assessed using the CCK assay is shown. B Human CRC cell lines were co-cultured with hPD-1 Jurkat-T cells and treated with the indicated concentrations of TER for 72 h. C PD-L1 protein expression in CRC cells co-cultured with hPD-1 Jurkat-T cells and treated with TER for 72 h. GAPDH was used as a loading control. The results are shown as the mean ± SEM. * <0.05, ** p < 0.01, *** p < 0.001, and **** p < 0.0001 compared with the respective control.

Article Snippet: Next, 5 μL of 0.5 mg/mL biotinylated hPD-1 (#71109, BPS Bioscience) was added, and the plates were incubated for 2 h at room temperature.

Figure Lengend Snippet: A The viability of hPD-1 Jurkat-T cells and hPD-L1 CHO cells following treatment with the indicated concentrations of TER for 24 h. B Luciferase activity measured using a PD-1/PD-L1 blockade bioassay. hPD-1 Jurkat-T cells (effector cells) were co-cultured with hPD-L1-expressing aAPC/CHO-K1 cells (target cells) in the presence of indicated concentrations of TER. The luminescence signal indicates the level of TCR signaling activation. αPD-L1 was used as a positive control. * <0.05, ** p < 0.01, *** p < 0.001, and **** p < 0.0001 compared with the respective control.

Figure Lengend Snippet: A The viability of hPD-L1 MC38 cells following treatment with the indicated concentrations of TER for 72 h. B CD8 + T cells were isolated from tumors of hPD-1 knock-in mice bearing hPD-L1 MC38 tumors. These tumor-infiltrating CD8 + T cells were co-cultured with hPD-L1 MC38 cells as target cells in the presence of TER for 72 h. Cell viability measured using the CCK assay is depicted. C PD-L1 expression in hPD-L1 MC38 cells, as assessed by western blot analysis using protein lysates from co-culture conditions. GAPDH was used as a loading control. D The levels of immune-related factors, including GrB, IL-2, and IFN-γ, measured in the co-culture supernatant by ELISA. * <0.05, ** p < 0.01, *** p < 0.001, and **** p < 0.0001 compared with the respective control.

Figure Lengend Snippet: A Body weight of hPD-1 knock-in mice during the treatment period. The mice were treated with vehicle or TER (10 or 30 mpk) for the indicated time. B Spleen weight of mice at the endpoint of the experiment. C Tumor volume was measured over time in hPD-1 knock-in mice bearing hPD-L1 MC38 tumors treated with vehicle or TER (10 or 30 mpk). Representative images of excised tumors from each group are shown. D Tumor weight at the endpoint of the experiment. E Flow cytometry analysis of CD8 + T-cell populations in tumors from each treatment group. F PD-L1 expression in tumors from each group, as assessed by western blot analysis. GAPDH was used as a loading control. G IHC staining of tumor sections for immune-related markers, including CD8 + T cells and GrB. Representative images from each group are shown, and the quantitation of marker-positive cells per field is presented. * <0.05, ** p < 0.01, *** p < 0.001, and **** p < 0.0001 compared with the respective control.
