MARCO and infection: Consistent with higher Ccl2 expression in WT mice at 12 and 16 hours after infection, the percentage (Figure 6E) and total number (Figure 6F) of inflammatory Ly6Chi monocytes (CD45+CD11c–CD11b+Ly6ChiLy6G–) in the dLN was significantly greater in WT mice at 12 and 16 hours after infection compared with MARCO–/– mice.
