عنوان انگلیسی Evaluating the Effects of Epigallocatechin-3-Gallate on HIF-1α Protein and RORC Gene Expression in Peripheral Blood Mononuclear Cells in Patients With Multiple Sclerosis
چکیده انگلیسی مقاله Introduction: Multiple Sclerosis (MS) is the chronic inflammation of the Central Nervous System (CNS) and autoimmune disease. MS is most widely considered to be mediated by the activation of myelin-specific T CD4+ cells as well as TH1 and TH17 cells. TH17 cells are involved in the pathogenesis of MS in various manners. HIF-1α and RORC are required for the natural differentiation of TH17; they are essential transcription factors for the evolution of TH17 cells. Numerous studies indicated that Epigallocatechin Gallate (EGCG) presents immunomodulatory and anti-inflammatory effects. This study investigated the effects of EGCG on normoxic HIF-1α and RORC2 expression in PBMCs among MS patients. Methods: Peripheral Blood Mononuclear Cells (PBMCs) were isolated from the whole blood of new cases of MS. The cells were cultured in the presence of a different concentration of EGCG (25, 50,100μM) for 18 and 48 hours. Next, HIF-1α and RORC2 level expressions were measured by Enzyme-Linked Immunosorbent Assay (ELISA) and Real-Time PCR, respectively.  Results: The results showed that EGCG significantly decreased RORC2 gene expression. EGCG did not affect the level of HIF-1α.  Conclusion: However, EGCG did not influence the level of HIF-1α. Our present data has led us to conclude that EGCG could be considered as an anti-inflammatory agent may serve as an achievable therapeutic agent for MS.
