Lung epithelial cells from Aoah−/− mice have defective innate responses to HDM. (A)
Aoah+/+ or Aoah−/− mice were instilled i.n. with HDM and 5 h later, cytokine/chemokine levels were measured in BALF using ELISA. Data were combined from three experiments. n = 6–9. (B) 5 h after HDM instillation, cytokine/chemokine mRNA were measured in lung homogenates using qPCR. Data were combined from two experiments. n = 6–8. (C) TLR signaling negative regulators Tnfaip3, SHIP, IRAK-M, and SOCS-1 mRNA levels were measured in lung homogenates. Data were combined from two experiments. n = 6–8. (D) 5 h after instillation of HDM, lung epithelial cells were sorted by using flow cytometry, and cytokine/chemokine mRNA were measured using qPCR. Data were combined from two experiments. n = 6–8. (E) Tnfaip3, SHIP, IRAK-M, and SOCS-1 mRNA levels were measured in sorted lung epithelial cells. Data were combined from two experiments. n = 6–8. (A–E) Mann-Whitney test was used. *, P < 0.05; **, P < 0.01; ***, P < 0.001.
