Anti-CD11b mAb administration to non-immunized mice led to modest depletion of all subsets of peritoneal myeloid cells (macrophage, DC and MDSC) at day 59 after tumor challenge, with the strongest effect being a ~4-fold depletion of granulocytic MDSCs (Supplemental Fig. 4). The gene discussed is ITGAM; the disease is neoplasm.
