Airway β-Defensin-1 Protein Is Elevated in COPD and Severe Asthma

Figure 3

β-defensin-1 and asthma severity. The airway expression of β-defensin-1 protein is higher in severe asthma (SA; ) compared with controlled asthma (CA, ) and uncontrolled asthma (UA, ) (Kruskal-Wallis test; ). The bars represent the median of each group. Dunn’s post hoc testing versus controlled asthma. Dunn’s post hoc testing versus uncontrolled asthma.
