Mesenchymal stem cells (MSCs) have been used clinically and experimentally to relieve severe immune-related diseases due to their immunomodulatory properties, but these are impaired by inflammation. Oral lichen planus (OLP) is a T cell-mediated chronic inflammatory mucosal disease. In the present study, we found MSCs from OLP with higher expression of interleukin (IL)-6, tumour necrosis factor alpha (TNF-α), transforming growth factor beta (TGF-β) and IL-10 compared with control. Total glucosides of paeony (TGP) significantly improves the immunomodulatory function of MSCs by inhibiting IL-6 and TNF-α expression and increasing TGF-β and IL-10 expression. Moreover, TGP can downregulate p-STAT3 expression through upregulation of miR-124. The changes of IL-6, TGF-β and p-STAT3 were further confirmed by overexpression and knockdown of miR-124 in MSCs. Taken together, the immune-regulating function of MSCs can be improved by TGP via the miR-124/STAT3 pathway.
