Within the CD11b+ Ly6G− compartment the proportions of Ly6Chi MHCII− monocytic cells, Ly6Chi MHCII+ intermediate cells, Ly6C− MHCIIhi CD64+ macrophages and Ly6C− MHCIIlo CD64+ macrophages were similar in colon and SI tumors and not altered by AOM treatment (Figure 3C). The gene discussed is ITGAM; the disease is infectious otitis media.
