| 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‐β, miR‐17, miR‐
27, and miR‐146A), and the secretion levels of IL‐10 and TGF‐β 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‐β factors in patients after
oxygen–ozone (O2‐O3) 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‐β 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. |
