Abstract
IL-4 plays an important role in the pathogenesis of atopic dermatitis (AD). Previously we showed that the expression of genes in chemotaxis, angiogenesis, inflammation and barrier functions is dysregulated in IL-4 transgenic (Tg) mice, a well-characterized AD mouse model. In this study, we aim to study differential expression of microRNAs in IL-4 Tg mice. As compared with wild-type mice, we found that 10 and 79 microRNAs are dysregulated in the skin of IL-4 mice before and after the onset of skin lesions, respectively. Bioinformatic analysis and previous reports show that these dysregulated microRNAs may be involved in the NF-κB, TLRs, IL-4/IL-13, MAPK and other pathways. We also found that miR-139-5p and miR-196b-3p are significantly up-regulated in the peripheral blood of IL-4 Tg mice. Taken together, our data have identified many dysregulated microRNAs in IL-4 Tg mice, which may play important roles in AD pathogenesis and pathophysiology.
