摘要

Multiple sclerosis (MS) is a common degenerative disorder of the central nervous system. The decreased frequency and dysfunction of Treg cells cause inflammation and disease progression. Ozone autohemotherapy can be used as a potential therapeutic approach to regulate the immune system responses and inflammation in MS. For this purpose, 20 relapsing-remitting multiple sclerosis patients were under treatment with ozone twice weekly for 6 months. The frequency of Treg cell, the expression levels of the Treg cell-related factors (FoxP3, IL-10, TGF-beta, miR-17, miR-27, and miR-146A), and the secretion levels of IL-10 and TGF-beta were assessed. We found a significant increase in the number of Treg cells, expression levels of FoxP3, miRNAs (miR-17 and miR-27), IL-10, and TGF-beta factors in patients after oxygen-ozone (O-2-O-3) therapy compared to before treatment. In contrast, oxygen-ozone therapy notably decreased the expression level of miR-146a in treated patients. Interestingly, the secretion levels of both IL-10 and TGF-beta cytokines were considerably increased in both serum and supernatant of cultured peripheral blood mononuclear cells in posttreatment condition compared to pretreatment condition. According to results, oxygen-ozone therapy raised the frequency of Treg cell and its relevant factors in treated MS patients. Oxygen-ozone therapy would contribute to improving the MS patients by elevating the Treg cell responses.
