Significant higher amounts of MIP-1α (Figure S10A), RANTES (Figure S10B), and TNF (Figure S10C) were produced by WT Hoxb8 neutrophils after HKMT- and LPS-stimulation or A. phagocytophilum infection compared to medium controls at 24–96 h p.i. For IL-6, this was only found for treatment with HKMT or LPS, but not for infection with A. phagocytophilum (Figure S10D). The gene discussed is CCL5; the disease is infection.
