Figure 3From: Treatment with a sphingosine analog after the inception of house dust mite-induced airway inflammation alleviates key features of experimental asthma AAL-R interferes with hallmarks of asthma induced by HDM. A) The degree of airway responsiveness was assessed by monitoring the change of respiratory system resistance (Rrs) during doubling doses of MCh. Paraffin-embedded tissue sections of lung stained with either H&E to assess B) inflammatory infiltrates in the peribronchial/perivascular regions or C) PAS to label mucus-producing cells. n = 4–5 mice per group and *indicates significant differences P <0.05. bar = 150 μm.Back to article page
