The Role of Exosomes/Extracellular Vesicles in Neural Signal Transduction.

ABSTRACT

Exosomes, in a broad sense extracellular vesicles (EVs), are secreted from several cells and also exist in cerebrospinal fluid (CSF); they contribute to signal transduction not only between neural cells but also among hematopoietic cells. In addition to the peripheral nervous system, the association of regeneration and EVs has also been reported in the central nervous system, for example, following a spinal cord injury. Furthermore, it has become clear that major causative factors of neurodegenerative diseases are transmitted by EVs; thus, EVs are involved in the pathogenesis of neurodegenerative diseases. In particular, we would like to outline the relationship between neurophysiology and neurological disorders centered on EV-mediated communication between neural and glial cells.
