Compared with controls, mRNA levels miR-155 (p<0.001), IL-25 (p<0.05), and IL-33 (p<0.001) were increased in nasal mucosa tissues of AR patients and AR mice, and ILC2s ratios were enhanced in human peripheral blood (p<0.0001), which were much higher after intranasal administration with miR-155 agomir (p<0.0001).
Recombinant IL‑37 (rIL‑37) inhibited the production of IL‑1p and IL‑6, and enhanced the production of IL‑27 in PBMCs from the patients with AR and the control individuals. rIL‑37 also markedly decreased the expression of IL‑17 by CD4+ T cells in the patients with AR and controls.
This randomized, placebo-controlled dose-response study was performed to analyze the effects of SLIT on FOXP3, IL-17, IL-23, and IL-27 expressions in peripheral blood mononuclear cells (PBMC) of children with allergic rhinitis and their associations with clinical outcome.
