چکیده

multiple sclerosis is a chronic inflammatory disease of the central nervous system characterized by a complex immune response. because of the complex nature of ms pathogenesis, a panel of biomarkers derived from different platforms will be required to reflect disease-related alterations. monitoring and evaluation of molecules associated with the pathogenesis of the disease would provide useful information on disease progression and therapeutic assessment. in view of this, we evaluated the mrna expression levels of b-cell activating factor (baff), high mobility group box 1 (hmgb-1), toll like receptor (tlr) 4 and tlr7 in ms. these molecules are implicated in the pathogenesis of ms; however, they havereceived little attention. pbmcs were isolated from whole blood of 84 relapsing remitting multiple sclerosis patients and 70 healthy controls. relative quantitative rt-pcr was applied to quantify the transcriptional levels of the immune markers. the mrna expression levels of tlr7 were significantly elevated in rrms patients than healthy controls. whereas, tlr4 expression was found to be significantly lower in the patients than control group. we found no difference analyzing the mrna levels of baff and hmgb1. our data highlights the immune marker correlates in rrms patients. however, further in-depth studies are warranted to check for their reliability of biomarkers in autoimmune diseases such as ms.

Increased Expression of miR-202-3p in Patients with Relapsing-Remitting Multiple Sclerosis

Background and objectives: One of the latest studies in the genetics field is the evaluation of role of micro-RNAs as a biomarker for diagnosis of multiple sclerosis (MS), which is a demyelinating disease of the central nervous system (CNS) and emerges in the form of numerous small and large plaques in white matter in the brain and spinal cord. This disease could be associated with several comp...

Alteration of OGG1, MYH and MTH1 genes expression in relapsing-remitting multiple sclerosis patients

Introduction: Previous studies revealed that oxidative stress is elevated in multiple sclerosis (MS). It can harm to biological macromolecules such as DNA. However, the molecular mechanism in protection of genetic information from DNA damages is not clear in MS disease. In this study the expression level of some important genes of OGG1 and MYH involved in base excision repair pathway and, MTH1 ...

Altered Expression of Circulating miR-377 and miR-98 in Relapsing-remitting Multiple Sclerosis

Background and Aims: Multiple sclerosis (MS) has been assumed to be a complex and indecipherable disease, and poorly understood with regard to etiology which is characterized by relapses and remissions. The expression of microRNAs (miRNAs) is known to be associated with the regulation of immune responses. Recently, investigations have reported that miRNA expression profiles in blood cells becom...

P37: Decreased Serum Levels of Interleukin-35 Among Patients with Relapsing Remitting Multiple Sclerosis

The regulatory role of interleukin-35 (IL-35) in the immunopathogenesis of multiple sclerosis (MS) is suggested in very few studies. We aimed to measure serum levels of IL-35 among clinically isolated syndrome (CIS) and relapsing-remitting MS (RRMS) patients and evaluate the associations between this cytokine and the disease clinical course. This cross-sectional study was conducted during 2017 ...
