ITGAM and neoplasm: After identification of DC by Zbtb46-GFP and their CD11c expression, we observed that similar to D4M tumors, a considerable proportion of DC in tumor-draining LN expressed FcγRI/CD64, which has been described as a monocytic/macrophage marker.46 50 Besides this CD64+ DC we split the CD64− DC into XCR1+ cDC1 and CD11b+ cDC2 (figure 5A).
