Finally, we validated the expression level of CST1 in Th2-high asthma group, Th2-low asthma group, and healthy control group (Figure 7E), and the diagnostic efficiency of CST1 in distinguishing Th2-high asthma from Th2-low asthma by using the GSE67472 dataset (Figure 7F). This evidence concerns the gene CST1 and asthma.
