ITGAM and neoplasm: Representative images of tumor section slides with multiplexed immunofluorescence staining are shown in Figure 7A. The levels of CD45+/PD-L1+ cells and CD11b+/PD-L1+ cells were significantly higher on days 4 and 7 in mice treated using 177Lu TRT than in saline-injected controls, whereas no significant difference was observed on day 14 (Figure 7 B-C).
