Selenized neural stem cell-derived exosomes: A neotype therapeutic agent for traumatic injuries of the central nervous system

SeNExo, a novel therapeutic agent developed from neural stem cell-derived exosomes, shows significant promise for treating traumatic injuries of the central nervous system (CNS). By functionalizing exosomes with ultrasmall nano-selenium, SeNExo enhances reactive oxygen species (ROS) scavenging and effectively penetrates the blood-brain barrier. In murine models of traumatic brain injury (TBI) and spinal cord injury (SCI), SeNExo significantly improves cognitive and locomotor functions, highlighting its potential as a new treatment strategy for CNS injuries.
