On the cover: Mice with an inducible deletion of the glucocorticoid receptor in alveolar type 2 cells were immunized and challenged with OVA to induce allergic airway inflammation. Leukocyte infiltration into the lung, bronchoconstriction and enhanced mucus production (Muc5B stained in brown) in mutant mice largely failed to resolve after dexamethasone treatment. Klaßen, C., A.
