Objective:
This study investigates the role of Epstein-Barr virus (EBV)-derived microRNAs (miRNAs) in the pathogenesis of multiple sclerosis (MS), aiming to elucidate their impact on immune-related molecular mechanisms.
Methodology:
This study was conducted at Ataturk University (Departments of Neurology and Medical Biology), between July 2022 and March 2025, the study included 40 MS patients and 40 healthy controls. Peripheral blood RNA samples were analyzed using Real-Time PCR to measure EBV miRNA and host mRNA expression. Data were evaluated using SPSS v23.
Results:
EBV-derived miRNA levels were significantly elevated in MS patients. Specifically, BART17-5p, BART10-5p, BHRF1-3 and BART5-3p levels were markedly increased (p<0.001). BART8-5p showed a negative correlation with CREB1 (r=-0.419; p=0.021), suggesting suppression of host signaling pathways. Immune markers such as CXCL3, MALT1, IFNB1, IL6, IL2 and FOXP3 also differed significantly between groups (p=0.005). Moderate correlations were noted between EBV-miRNAs and immune genes (e.g., IFNB1 and BART10-5p: r=0.433; p=0.017). Weak negative correlations were found between BART8-5p and multiple immune-related genes (e.g., IL1B, STAT3, CD4) and between BART19 and IL2 (r=-0.373; p=0.043). Logistic regression revealed that increased BART miRNA levels were associated with elevated MS risk.
Conclusion:
EBV-derived miRNAs are linked to immune activation and may contribute to MS pathogenesis. These miRNAs may serve as potential biomarkers and therapeutic targets in MS management.
Insights
Epstein-Barr virus (EBV)-derived microRNAs (miRNAs) are elevated in multiple sclerosis (MS) patients, correlating with immune markers and increased MS risk. These EBV miRNAs may be potential biomarkers and therapeutic targets for MS.
Area of Science:
- Virology
- Immunology
- Neuroscience
Background:
- Multiple sclerosis (MS) is a chronic autoimmune disease affecting the central nervous system.
- The role of viral infections, particularly Epstein-Barr virus (EBV), in MS pathogenesis is an area of active research.
- MicroRNAs (miRNAs) are small non-coding RNAs that regulate gene expression and are implicated in various diseases, including MS.
Purpose of the Study:
- To investigate the expression levels of EBV-derived miRNAs in patients with multiple sclerosis (MS).
- To determine the correlation between EBV-derived miRNAs and host immune gene expression in MS.
- To explore the potential of EBV-derived miRNAs as biomarkers and therapeutic targets in MS.
Main Methods:
- Peripheral blood samples were collected from 40 MS patients and 40 healthy controls.
- Real-Time PCR was used to quantify EBV miRNA and host mRNA expression.
- Statistical analysis, including logistic regression, was performed to evaluate the data.
Main Results:
- EBV-derived miRNA levels, including BART17-5p, BART10-5p, BHRF1-3, and BART5-3p, were significantly elevated in MS patients compared to controls (p<0.001).
- Significant differences in immune markers (CXCL3, MALT1, IFNB1, IL6, IL2, FOXP3) were observed between MS patients and controls (p=0.005).
- Correlations were found between specific EBV miRNAs and immune genes, and increased BART miRNA levels were associated with elevated MS risk.
Conclusions:
- EBV-derived miRNAs are significantly associated with immune activation in multiple sclerosis.
- These viral miRNAs may play a role in the pathogenesis of MS.
- EBV-derived miRNAs represent potential diagnostic biomarkers and therapeutic targets for managing MS.
