Extended Data Fig. 1 |. IL-33 is mainly expressed in airway epithelium cells both in humans and mice.
a, Microscopy of the immunofluorescent (IF) stained SPC (green) expressing AT2 cells and IL-33(red) expressing cells in lung tissue from WT Balb/c mice without any stimulations. b, Representative microscopy of the immunohistochemically (IHC) stained IL-33 (brown) in airway epithelium respective in inflamed asthma patients and non–inflamed lung tissues. Scale bars 50 μm. Data are representative of two independent experiments.
