Endogenous TSLP neutralization decreased Alternaria extract (Alt‐Ext)‐induced type‐2 airway inflammation. A, Anti‐TSLP antibody (α‐TSLP) or the isotype antibody was administered subcutaneously 1 h prior to first Alt‐Ext‐challenge. Bronchoalveolar lavage fluid (BALF) and lung were harvested 24 h after the 4th Alt‐Ext‐challenge. B, Cell differentials in BALF. C, The protein level of IL‐4, IL‐5, and IL‐13 in the lung homogenates. The data are a combination of 2 independent experiments and shown as mean ± SD (n = 4‐9). *P < .05
