Research Abstract

Exosome is a subtype of extracellular vesicle, released from various cells including brain neurons. A well known function of exosome is to remove obsolete or misfolded proteins from cells, however, the mechanism how exosomes are processed in extracellular space of brain remained unclear. In this study, we searched type of cells, which can uptake neuronal exosomes, and found that microglia can uptake the exosomes and degrade the exosome-associated proteins.
