Heat-killed C cladosporioides prevents murine asthma in a Dectin-1–dependent manner. A, Wild-type C57BI/6 or Dectin-1−/− mice were exposed to heat-killed C cladosporioides spores, and AHR was assessed 48 hours later. B, Total and differential counts of BALF. Data are representative from 2 independent experiments and are expressed as mean and SEM. n = 4 to 6 mice per group. C clad HK, Heat-killed C cladosporioides; Eos, eosinophils; KO, knockout; Lymp, lymphocytes; Mac, macrophages; Neut, neutrophils; WT, wild type. **P < .01 and ***P < .001 as compared with saline. ##P < .01 and ###P < .001 as compared with wild-type mice exposed to C cladosporioides.
