IL5 and asthma: What's more, as shown in Table 4, the levels of IL‐1β (p = 0.025), IL‐5 (ratio of acute asthma episodes to stable asthma episodes (p = 0.024), IL‐6 (p = 0.018), TNF‐α (p = 0.011), IFN‐γ (p = 0.011), CCL17 (p = 0.025), CCL22 (p = 0.021), IL‐12p70 (p = 0.015), C−X−C‐motif chemokine 10 (CXCL10) (p = 0.048), CCL4 (p = 0.023), CCL2 (p = 0.048), CCL13 (p = 0.025), IL‐4 (p = 0.018), IL‐13 (p = 0.024), and CCL11 (p = 0.028) were found to be downregulated in the serum of patients with stable asthma compared to those with acute asthma.
