Research advances of mesenchymal stem cell in allergic rhinitis

Allergic rhinitis is a chronic nasal mucosal inflammation characterized by upper airway hyperresponsiveness, involving a variety of immune cells and inflammatory mediators. Drugs, immunotherapy, and surgical operation are the principal treatments at present. The study found that mesenchymal stem cells have the ability of immune regulation and have a promising clinical application in the treatment of allergic rhinitis. In this review, the action mechanism of mesenchymal stem cells, the immunomodulatory effect of mesenchymal stem cells on the key cells of allergic rhinitis, and the challenges of clinical application are reviewed, to provide new directions for the treatment of allergic rhinitis.
