Aim of the Study: Multiple sclerosis (MS) is an autoimmune disorder causing demyelination in axons. Available therapies target different molecules, but not all have therapeutic effects on disease progression, and this effect can only be seen after a long-time administration. Interferon beta (IFN-β), an MS therapy for many years, slows down the disease progression and reduces disease symptoms by targeting T cells. Yet, a considerable portion of the patient has experienced no therapeutic response to IFN-β. It is necessary to determine disease-specific biomarkers which allow early diagnosis or treatment of MS. Here, it was aimed to determine the effects of interleukin 10 (IL10) and 23 (IL23A) as well as forkhead box P3 (FOXP3) genes on MS after IFN-β therapy. Materials & Methods: Peripheral blood mononuclear cells (PBMCs) were extracted to isolate CD4+ and CD25+ T cells. Cytotoxicity assays were performed on each cell type for determining optimum drug concentration. Then, cells were cultured and determined drug concentration was administered to the cells to measure gene expressions with RT-PCR. Results: It was found that the cytotoxic effect of IFN-β was more efficient as the exposure time was expanded regardless of drug concentration. Moreover, CD25+ T lymphocytes were more resistant to IFN-β. IL23A was down-regulated, whereas FOXP3 was up-regulated at 48h in CD4+ T cells. For CD25+ T cells, the graded increase of FOXP3 was obtained while IL10 expression was gradually decreased throughout the drug intake, significantly. Conclusion: Although considerable change in expression was obtained, the long-term IFN-β effect on both genes and cells should be determined by follow-up at least a year.
