The lung of each mouse was lavaged with 3 × 0.5 ml of sterile saline according to previously described59 (link),60 (link). The BALF was centrifuged at 250 × g for 10 min. The pellet was resuspended with 1 ml of sterile saline, and then the cells were mounted on a slide by cytospin centrifuge (Hettich ROTOFIX 32 A) at 1000 rpm for 3 min.
