Abstract

Background: Multiple Sclerosis (MS) is an autoimmune and inflammatory disorder of the central nervous system (CNS), which is associated with the imbalance of pro- and anti-inflammatory cytokines. Evidence indicates that nutritional interventions have some immunomodulatory impacts. Objectives: In this study, we investigated the effect of olive vegetation water (OVW) on IFN-γ and IL-10 secretion by peripheral blood mononuclear cells (PBMCs) of MS patients. Methods: In this study, PBMCs of MS patients were separated by Ficoll-Hypaque centrifugation. The cytotoxicity of OVW was assessed by the MTT assay. The treatments were performed for 48 and 72 hours, and IFN-γ and IL-10 were measured by ELISA. Results: No cytotoxicity was observed for OVW. Besides, OVW showed a significant inhibitory effect on IFN-γ secretion but augmenting effect on IL-10 secretion by PBMCs dose-dependently. Conclusions: This study indicated that OVW could have immunoregulatory effects on inflammatory reactions in MS patients.
