FCER1A and asthma: The expression levels of FCER1A (Figure 3A) and TLR‐9 (Figure 3F) in IL‐5‐ or IL‐17‐activated eosinophils and those of aryl hydrocarbon receptor (Figure 3C) and TLR‐7 (Figure 3E) in IL‐5‐activated eosinophils were significantly higher for patients with asthma than for normal individuals.
