Expression and enzyme activity of MnSOD and catalase in peripheral blood mononuclear cells isolated from multiple sclerosis patients

ABSTRACT

Background: it is evident that oxidative stress plays a crucial role in etiology of multiple sclerosis [MS]. Dysregulation of antioxidant enzymes have been implicated in demylination and neuronal loss in MS. The aim of this study was to evaluate mRNA expression and activity of manganese superoxide dismutase [MnSOD], and catalase in peripheral blood mononuclear cells [PBMCs] from patients with relapsing-remitting multiple sclerosis [RRMS] and healthy controls
