NaR9 effectively protects mice from airway hyperresponsiveness (AHR) and Th2-mediated lung inflammation. (a) Protocol used for NaR9 treatment. (b) AHR of the mice indicated was measured by administering methacholine (Mch). (c, d) In bronchoalveolar lavage fluid (BALF), total numbers of cells and numbers of eosinophils were counted. (e) Proportions of eosinophils and neutrophils in BALF were measured by flow cytometry using the markers indicated. (f) Representative images of hematoxylin and eosin stained histologic sections of mouse lungs. Scale bars, 200 μm. The inflammatory score (0 to 3) was statistically analyzed. (g) Lung Il13, Il5, and Hprt mRNA levels were measured in the mice indicated. (h) Mediastinal lymph node cells from house dust mite (HDM)-sensitized mice were restimulated with HDM (10 or 30 μg/mL). Five days later, IL-5, IL-13, and IL-17a were measured in the culture supernatants by ELISA. Data are presented as means ± SD of three independent experiments (n = 4 or 5 each). n.s. not significant, WT wild type, i.t. intratracheally, Rrs respiratory resistance.
