CCR2 and infection: We observed that i.d. infected CCR2−/− mice display delayed monocyte recruitment and a higher rate of neutrophils at 7 days post infection in the footpad lesion (Figure S10B) associated with an increased CFU count in the footpad lesion, popliteal draining LNs, and spleen (Figure 9), confirming the importance of monocyte recruitment in the local and systemic control of Brucella infection.
