Lung cells were blocked with anti‐mouse CD16/32 (101319; Biolegend) and then stained with antibodies PerCP anti‐mouse/human CD11b (101229; Biolegend), Brilliant Violet 421 anti‐mouse F4/80 (123137; Biolegend), APC/Cy7 anti‐mouse CD45 (103116; Biolegend), PerCP/Cy5.5 anti‐mouse CD11c (117328; Biolegend), PE Siglec‐F (552126; BD Biosciences), PerCP/Cy5.5 anti‐mouse CD4 (100540; Biolegend), PE/Cy7 anti‐mouse CD3ε (100320; Biolegend), Brilliant Violet 421 anti‐mouse CD335 (NKp46) (137612; Biolegend), APC anti‐mouse CD8a (100712; Biolegend), Brilliant Violet 421 anti‐mouse Ly‐6G/Ly‐6C (Gr1) (108433; Biolegend) and Zombie Aqua Fixable Viability Kit (423102; Biolegend). Flow cytometric data acquisition was performed on BD FACS Canto II machine and data analysis was performed using FlowJo software.
Gating for CD45+AquaZombie−Siglec‐F+CD11c+Gr1− cells was used for AMs; CD45+AquaZombie−F4/80+CD11b+Gr1− for IMs CD45+AquaZombie−NKp46+ for natural killer (NK) cells, CD45+AquaZombie−CD3+CD8+ for CD8 T cells.
