Stroke is a complex and life-threatening disease that is one of the leading causes of mortality and disability in the world. Due to the high incidence, there is an urgent need to develop strategies for stroke management. Exosomes are nano-sized extracellular vesicles (EVs) that have the capability to transport active substances including microRNA (miRNA) to recipient cells. A growing number of studies have shown that exosomes are an important factor in the initiation and progression of stroke. Therefore, a greater understanding of the role of exosomes and their contents in the pathogenesis of stroke could help in the discovery and development of new therapeutic approaches. In addition, exosome miRNAs have been shown to be a non-invasive biomarker for stroke diagnosis and monitoring.

The role of exosomes in stroke

Stroke is the most common cause of permanent disability in adults as well as the second-most common fatal disease in both developing and developed countries. The pathophysiology of this disease is highly associated with both genetic and environmental factors. Stroke can be divided into two subtypes, including ischemic and hemorrhagic stroke. Among them, ischemic stroke is mainly caused by thromboembolism or atherosclerosis of the blood vessels supplying the brain, which in turn leads to cerebral ischemia and hypoxia, accounting for about 87% of all strokes.

Stroke recovery is a highly interactive process involving neural stem cells and neurovascular units, in which exosomes play an important role. After a stroke, brain cells, blood cells, and endothelial cells release exosomes in response to stroke. These EVs can promote nerve regeneration, enhance neurological recovery, and regulate peripheral immune responses, participating in increasing long-term neuroprotection after stroke. Moreover, they also enhance angiogenesis, neurogenesis, axon dendritic remodeling, and brain reconstruction. Along with beneficial effects, these exosomes can also have adverse effects on distal organs, including the spleen, heart, kidney, and intestine. Exosomes in stroke have not been adequately studied compared to exosomes in tumors. Currently, studies on exosomes in stroke have focused on the neuroprotective and neuroprosthetic effects of mesenchymal stem cell (MSC)-derived exosomes.
