ONLINE COVER Brush Strokes. The cover features an immunofluorescence image showing three brush cells in mouse tracheal epithelium that co-express the chemosensory cell marker doublecortin-like kinase 1 (DCLK1; green) and the cytokine interleukin-25 (IL-25; red). Airway brush cells display a characteristic tuft of microvilli at their apical tip and express receptors also found in taste-sensing cells. Bankova et al. report that aeroallergen inhalation induces an increase in IL-25–producing brush cells that depends on the lipid mediator leukotriene E4 activating the cysteinyl leukotriene 3 receptor.
