Abstract
AbstractReperfusion therapy, employed in the treatment of acute stroke, frequently proves to be inadequate in addressing the primary brain tissue injury and may even give rise to secondary damage. The study introduces a satellite nanoparticle platform named MEps, which combine the neural repair properties of bone marrow mesenchymal stem cell exosomes (Exos) with the inflammatory site‐targeting abilities of macrophage membranes (MMs). MMs and Exos in MEps act like satellites, ensuring precise positioning and information transmission. MEps rapidly form a protective barrier on the damaged cerebral vascular endothelial cells through the interaction of adhesion molecules with their receptors, blocking the infiltration of neutrophils. Subsequently, repair factors in Exos repair the damaged cells and initiate neurogenesis. The results indicate that this innovative approach effectively mitigates ischemic‐reperfusion injury at multiple levels and demonstrates strong biocompatibility. This strategy holds promise for clinical applications in alleviating ischemic‐reperfusion injury.
