Exosomal microRNA and stroke: A review

Area of Science:

• Neuroscience
• Molecular Biology
• Biochemistry

Background:

• Stroke, caused by brain blood vessel rupture or occlusion, is a leading global cause of death and disability.
• Current therapeutic strategies for stroke remain limited, with many preclinical neuroprotective agents failing in clinical trials.
• MicroRNAs (miRNAs) are small noncoding RNAs regulating cellular pathways, and their dysregulation is implicated in stroke initiation and progression.

Purpose of the Study:

• To review the role of exosomal microRNAs (miRNAs) in the pathogenesis of stroke.
• To highlight the potential of exosomal miRNAs as therapeutic targets and noninvasive biomarkers for stroke.

Main Methods:

• Literature review of studies investigating exosomal miRNAs in stroke.
• Analysis of the mechanisms by which exosomal miRNAs influence stroke pathology.
• Evaluation of exosomal miRNAs as diagnostic and prognostic indicators in stroke.

Main Results:

• Exosomes act as crucial nano-carriers, transferring miRNAs that significantly contribute to stroke pathogenesis.
• Specific exosomal miRNAs have been identified as key players in the molecular and cellular events underlying stroke.
• Exosomal miRNAs demonstrate potential as noninvasive biomarkers for stroke diagnosis and monitoring treatment response.

Conclusions:

• Exosomal miRNAs are integral to stroke pathogenesis, offering novel insights into disease mechanisms.
• Targeting exosomal miRNAs presents a promising avenue for developing innovative stroke therapeutics.
• Exosomal miRNAs hold significant potential for noninvasive diagnosis and personalized therapy monitoring in stroke patients.
