Circular RNAs: A New Approach to Multiple Sclerosis.

Area of Science:

• Neuroimmunology
• Molecular Biology
• Genetics

Background:

• Multiple sclerosis (MS) involves central nervous system demyelination and axonal damage, driven by autoreactive immune cells targeting myelin antigens.
• Immune system dysregulation, including deficiencies and autoimmunity, can lead to disorders like MS.
• Non-coding RNAs (ncRNAs) are crucial regulators of gene expression and cellular functions, implicated in immune disorders.

Purpose of the Study:

• To review and investigate the role of circular RNAs (circRNAs), a class of ncRNAs, in the pathogenesis of multiple sclerosis (MS).
• To explore how circRNAs influence post-transcriptional regulation, gene expression, and epigenetic factors relevant to MS.

Main Methods:

• Literature review focusing on recent studies concerning circRNAs and their involvement in neuroimmune diseases.
• Analysis of the mechanisms by which circRNAs contribute to MS-specific pathologies.

Main Results:

• CircRNAs are shown to influence microRNA activity and epigenetic modifications, contributing to MS hallmarks.
• These circRNAs play a role in promoting neuroinflammation, neuronal cell damage, and microglial dysfunction in MS.

Conclusions:

• Increased knowledge of circRNAs in MS pathogenesis offers potential for novel diagnostic and therapeutic strategies.
• Understanding circRNAs may lead to a paradigm shift in viewing and managing this complex neuroimmune condition.
