CCL2 and infection: Importantly, the infection of MCP-1 KO mice with these pathogens showed that the migration of inflammatory monocytes and neutrophils from the bone marrow to the blood (Figure 2B,C) causes a reduction of 6.76 ± 1.55% to 2.17 ± 1.14% (p = 0.049) and from 12.67 ± 1.37% to 4.13 ± 0.99% (p = 0.043), respectively, for A. baumannii infection.
