(A) Splenic Lm quantification in WT or CD169-DTR mice at 24 and 48 hpi. Each symbol represents an individual mouse. Data are shown as means ± SEM (*P < 0.05 and **P < 0.005, Mann-Whitney test). (B) Confocal images of WT or CD169-DTR mice at 24 hpi. Spleen sections stained for Lm (green) and Ly6G (red). Lm are rendered using spots. White arrowheads indicate Lm foci devoid of neutrophil clusters. Scale bars, 100 μm. (C) Confocal images of spleen sections from WT or CD169-DTR mice at 24 hpi showing organized clustering versus disrupted hierarchical clustering of innate immune cells. Lm are rendered with spots in green. CD169+ macrophages are shown in blue, NK cells are shown in red, and CD11b+ cells are shown in turquoise. Scale bars, 100 μm. (D) Representative images of spleen sections showing IFN-γ (yellow), NK1.1 (red), and Lm (white). Lm are rendered with spots. Scale bars, 80 μm. (E and F) Lm numbers quantified from (E) lungs and (F) brains of WT or CD169-DTR mice. ND, not detected. Each symbol represents an individual mouse. Data are shown as means ± SEM (*P < 0.05 and **P < 0.005, Mann-Whitney test). All data are representative of two to four separate experiments with two to four mice per group. Oriana A. Perez et al.
