CD70 and neoplasm: To investigate the mechanism of action of LAIR1 in M2-like MΦ, we performed scRNA-Seq analysis (the cell population categorization used in the analysis is shown in Supplemental Figure 12) using tumor samples from total 6 KR158B-CD70-Luc TB mice treated with IgG or anti-Lair1 antibody, which showed a trend of antitumor efficacy (Supplemental Figure 13A).
