Significant decreases in CCL3, CCL4, and CXCL2 were observed in the galea of TNF KO mice at day 14 post-infection (Fig. 3A), corresponding to the timepoint and anatomical location where granulocyte recruitment was maximally reduced (Fig. 1E; Additional File 1: Fig. S2E). The gene discussed is CXCL2; the disease is infection.
