The same batch of human bronchial epithelial cells in exponential growth phase was randomly divided into five groups： blank group （A）, 300 ng/mL HDM group （B）, 1000 ng/mL HDM group （C）, 3000 ng/mL HDM group （D）, and 300 ng/mL HDM＋100 ng/mL DEX group （E）. The IL-29 mRNA expression was detected by quantitative reverse transcription polymerase chain reaction （qRT-PCR）. The IL-29 protein expression in cell sus- pension was detected by ELISA. The results showed that after stimulation with HDM for 24 h, the ex- pression oflL-29 was increased significantly, and after co-stimulation with HDM and DEX for 24 h, the expression oflL-29 in group E was significantly lower than that in the groups stimulated by HDM alone but higher than that in the group A. The differences between the different groups were significant （F=132.957, P〈0.01）. Additionally, the higher the concentration of HDM was, the more significant the increase in the IL-29 expression was. In conclusion, IL-29 may play a role in the progression of airway allergic disease including asthma.展开更多
