Signal transduction of exosomes in cerebral ischemia

Exosomes are extracellular vesicles released from various cellular sources and are widely present in body fluids. Bioactive substances such as microRNAs, mRNAs, and proteins are encapsulated in exosomes, which can activate various signaling pathways and play important roles in early warning of stroke and neurovascular unit repair. This article reviews the signal transduction of exosomes in cerebral ischemia. Key words: Stroke; Brain ischemia; Exosomes; MicroRNAs; Signal transduction
