DEmiRs affecting CD4+ T cell development. Hypothetical network of DEmiRs affecting T helper (Th) cell maturation. Downregulated miR-128 is known to promote Th cell development towards the Th2 side while negatively regulating Th1 cell maturation. Additionally, IL6 production is increased by downregulated miR-128 while TGFβ production is enhanced by downregulated miR-744. We hypothesize that this leads to an increased Th2/Th17 immune response upon antigen challenge rendering certain horses susceptible to develop severe equine asthma. This hypothesis is supported by a previous finding of downregulated interferon gamma (IFNG) and upregulated C-X-C motif chemokine ligand 13 (CXCL13) in PBMCs of the same affected horses.
