On the cover: Thickening of the airway epithelium induced by exposure to FIZZ1, a resistin-like molecule that is highly upregulated in the epithelium in mice after one challenge with the severe asthma-associated allergen Alternaria. H&E-stained lung section is shown. Doherty, T. A., N. Khorram, K. Sugimoto, D. Sheppard, P. Rosenthal, J. Y. Cho, A. Pham, M. Miller, M. Croft, and D. H. Broide. 2012. Alternaria induces STAT6-dependent acute airway eosinophila and epithelial FIZZ1 expression that promotes airway fibrosis and epithelial thickness. J. Immunol. 188: 2622–2629.
