As opposed to the peritumor regions, the amount of CD3+ T cells and the amount of PD-L1+ cells were positively correlated in the intratumor regions (Figure 1E, remaining). Syngeneic mouse model tests proven that TAMs indicated PD-L1 and tumors treated with anti-PD-L1 demonstrated smaller sized diameters than those treated with IgG. In these mice, anti-PD-L1 […]
