At the same time, IL-17RB (9.83 ± 0.35), RORα (7.18 ± 0.71), and GATA-3 (4.86 ± 0.66) mRNA expression levels in the bronchiolitis group were greater than those (9.19 ± 0.58, 5.46 ± 1.09, and 4.19 ± 0.90, respectively) in the control group, and the differences between the two groups were statistically significant (P < 0.05, see Fig. 2). The gene discussed is GATA3; the disease is bronchiolitis.
