Figure Lengend Snippet: ( A – K ) Csk fl/fl Lyz2 wt/wt and Csk fl/fl Lyz2 cre/wt mice were subjected to K . pneumoniae intratracheal injection or sham surgery. After 24 hours, bacterial burden regarding the colony forming units (CFUs) in lung ( A ), bronchoalveolar fluid (BALF) ( B ), blood ( C ), and spleen ( D ) and neutrophil recruitment into the lungs ( E ) and BALF ( F ) were determined. ( G ) Neutrophil recruitment (CD45 + Gr-1 + LyB.2 + ) in Csk fl/fl Lyz2 wt/wt and Csk fl/fl Lyz2 cre/wt mice in the interstitial, intravascular, and BALF compartments following intratracheal instillation of K . pneumoniae . Cell count of monocytes (MO; CD45 + CD11b + CX3CR1 + Ly6C hi Ly6G – Gr-1 – ) ( H ), alveolar macrophages (AM; CD45 + CD64 + F4/80 + MARCO + SiglecF hi ) ( I ), natural killer cells (NK; CD45 + CD27 + CD335 + ) ( J ), and dendritic cells (DC; CD45 + CD27 – CD24 + CD11c + MHCII + ) ( K ) in lung tissue 24 hours after lung infection. n as indicated, mean ± SEM. * P < 0.05; ** P < 0.01; *** P < 0.001; **** P < 0.0001 by 1-way-ANOVA by Holm-Šídák multiple-comparison test ( A – D ), 1-way ANOVA with Tukey’s multiple-comparison test ( E , F , and H – K ), or 2-tailed Student’s t test ( G ).
Article Snippet: Alveolar macrophages were gated as CD45 + CD64 + F4/80 + MARCO + SiglecF hi using antibodies against CD45 (clone 30-F11, BioLegend), CD64 (clone X54-5/7.1, BioLegend), F4/80 (clone BM8, BioLegend), MARCO (clone 579511, R&D Systems), and SiglecF (clone S17007L, BioLegend).
