Mice were challenged with either vehicle, one of three allergens (HDM, CRE, Alt)
or one of three nucleotides (ATP, UPD-glucose, ADP), and euthanized 2 and 72
hours after challenge. (A) IL-33 expression in bronchoalveolar
lavage fluid (BALF) collected 2 hours post challenge. Total number of
eosinophils (B) and lymphocytes (C) recruited to the
BALF at 72 hours post challenge, based on flow cytometry analysis. Veh: vehicle.
HDM: house dust mite. CRE: cockroach. Alt: alternaria.
