IFNAR1 expression level in Iranian multiple sclerosis patients treated with IFN-B

Area of Science:

• Neuroimmunology
• Genetics

Background:

• Multiple sclerosis (MS) is an autoimmune, inflammatory, and demyelinating disease of the central nervous system.
• The specific role of certain genes, such as IFNAR1, in MS initiation requires further investigation in diverse populations.

Purpose of the Study:

• To investigate the function of the IFNAR1 gene in the Iranian population.
• To compare IFNAR1 gene expression levels between relapsing-remitting MS (RR-MS) patients and healthy individuals.

Main Methods:

• Quantitative RT-PCR was used to measure IFNAR1 gene expression levels.
• Whole blood RNA was extracted from 50 RR-MS patients and 50 healthy controls.
• Patient cohort included HLA-DRB1*15 negative individuals responding to interferon-beta with normal vitamin D levels.

Main Results:

• RR-MS patients exhibited significantly higher IFNAR1 gene expression compared to controls (p=0.012).
• Females aged 30-40 showed a significant increase in IFNAR1 expression (p=0.046).
• Males under 30 demonstrated a significant decrease in IFNAR1 expression (p=0.04).
• Female patients, specifically, showed a statistically significant increase in IFNAR1 expression (p=0.004).

Conclusions:

• IFNAR1 levels are elevated in MS patients treated with interferon-beta.
• The study suggests a potential role for IFNAR1 in the pathogenesis or treatment response of MS.
