MicroRNAs and multiple sclerosis: from physiopathology toward therapy

Area of Science:

• Molecular Biology
• Immunology
• Neuroscience

Background:

• MicroRNAs (miRNAs) are small noncoding RNAs regulating gene expression post-transcriptionally.
• miRNAs are crucial in immune cell development, activation, and response.
• Emerging evidence links miRNAs to autoimmune diseases, including multiple sclerosis (MS).

Purpose of the Study:

• To review miRNA biogenesis and their roles in disease-relevant cells.
• To summarize current knowledge on miRNA involvement in autoimmune pathogenesis.
• To explore potential therapeutic applications of miRNAs in diseases like MS.

Main Methods:

• Literature review of MEDLINE and ScienceDirect databases.
• Synthesis of current research on miRNA function in immunity and disease.
• Analysis of diagnostic, prognostic, and therapeutic implications of miRNAs.

Main Results:

• miRNAs are implicated in the pathogenesis of autoimmune diseases and MS.
• miRNAs found in central nervous system lesions and blood show potential as diagnostic and prognostic biomarkers.
• miRNA-based therapeutics, including mimics and inhibitors, are being developed.

Conclusions:

• miRNAs are significant players in the immune system and autoimmune disease development.
• miRNAs in biological samples offer potential for early disease detection and outcome prediction.
• Targeted miRNA modulation presents a promising therapeutic strategy for MS and other autoimmune conditions.
