Abstract: (6936 Views)
Background: Allergic Asthma is an inflammatory disease of the respiratory system that is well known by increased inflammatory cells in the airways and causes difficulty in respiration. The prevalence of allergic asthma is increasing worldwide, and it has become a significant cause of health challenge especially in developed countries. Inhaled β2-agonists and Inhaled or oral corticosteroids are common medications for treating the disease, but they cannot be used for long periods of time because of frequently occurring side effects and they can’t change the main pathogenesis of the problem. Deficiency in regulatory system against inflammation could be an important factor in allergic asthma. Mesenchymal stem cells (MSCs) have potential of cellular immunosuppressive therapy of inflammatory disorders. The aim of present study was to evaluate the effects of MSC therapy on mechanisms of allergic asthma in mice model.
Methods: This experimental study was conducted from August 2014 to March 2015. The animals were housed and maintained in Biotechnology Center of Urmia University, Iran. Mice were sensitized by intra-peritoneal injection of ovalbumin (OVA) and aluminum hydroxide emulsion and then were challenged intra-nasally with OVA. Before allergen challenge on day 14, experimental mice received tail vein injection of MSCs in PBS. Regulatory T cells of spleen, cytokines and IgE analysis were carried out using lungs wash as well as serum samples.
Results: Our results showed that MSCs significantly reduced total cells and eosinophilia, serum OVA-specific IgE concentration in OVA-sensitized and challenged mice. Also results showed that MSCs markedly inhibited expressions of Th2 cytokines and elevated levels of Treg cells and Treg cytokines.
Conclusion: In the present study, we demonstrated the inhibitory effect of MSCs on airway inflammation using mice model of allergic asthma. The mice were sensitized with OVA and compared to the results of dexamethasone administration. Our results demonstrated that administration of MSCs could be used as a potential therapeutic approach for the allergic asthma.
