CD274 and neoplasm: Notably, although, the proportion of Kaede Green+ CD8 T cells within responder or non-responder tumors was comparable with isotype controls, again indicating that the proportion of CD8 T cells recruited into the tumor was not altered by the targeting PD-L1 tumor (Fig. S5 S), we further observed that anti–PD-L1 Abs increased both the proportion and number of TCF-1+ PD-1+ CD8 T cells within the tumor (Fig. S5, T–X).
