Molecular Pathways Underlying the Therapeutic Effect of Stem Cells during Asthmatic Changes

Allergic asthma is a chronic inflammatory disease characterized by airway remodeling, hyperresponsiveness, and exacerbated inflammation. While most patients respond well to current treatments, a small subset remains resistant necessitating new therapeutic strategies. Due to their immunomodulatory properties, stem cells have been proposed as a promising treatment option for asthma. Stem cells can reduce airway inflammation and restore immune balance, demonstrating positive outcomes, particularly in cases of steroid-resistant asthma. However, the mechanisms underlying lung tissue repair are not clearly defined. On the other hand, there are limitations in using these cells and for clinical use of mesenchymal stem cells, which must be produced in accordance with Good Manufacturing Practice. This review article discusses the mechanisms by which stem cells may aid in asthma treatment and addresses and explores the challenges associated with their use. By addressing these areas, we can better understand the potential and limitations of stem cell therapy in asthma and develop more effective strategies to harness their therapeutic benefits for patients with uncontrolled asthma.
