To analyze immune lung infiltration, lung suspensions were stained as previously described [20 (link)] using the following directly conjugated antibodies: CD3e FITC (Miltenyi, Miltenyi Biotec GmbH, Bergisch Gladbach, Germany, clone 145-2C11); CD11b PE (BD Biosciences, San Jose, CA USA, clone M1/70); CD11c PECY7 (Thermo Fisher Scientific-eBiosciences, clone N418); CD45 APCeFluor780 (Thermo Fisher Scientific-eBioscience, clone 30-F11); CD49b PE (Miltenyi, clone DX5); CD69 APC (Miltenyi, clone H1.2F3); CD103 APC (Miltenyi, clone REA789); B220 PERCPVio700 (Miltenyi, clone RA3-6B2); and mPDCA-1 PE (Miltenyi, clone JF05-1C2.4.1). A purified rat anti-mouse CD16/CD32 MAb (Thermo Fisher Scientific-eBioscience, clone 93) was used to block nonspecific binding to mouse Fc receptors. The cells were analyzed using a FACSCanto flow cytometer (BD Biosciences) and FlowJo software (TreeStar). All analyses were performed using gating on CD45+ live cells after doublet exclusion.
