Nasal administration of Xingnaojing biomimetic nanoparticles for the treatment of ischemic stroke
Xingnaojing injection (XNJ), is the first-line Chinese medicine injection approved for treating ischemic stroke (IS). XNJ can attenuate the inflammatory responses and oxidative stress, thus reversing neuronal damage of IS. This study aims to prepare the biomimetic nanoparticles (Bo-GEVs/XNJM) of nasal administration for IS treatment. The grapefruit extracellular vesicles (GEVs) loaded with microemulsions sourced from Xingnaojing injection (XNJM) are modified with borneol (Bo) to bypass the blood–brain barrier (BBB). Bo-GEVs/XNJM has the property of brain-targeting, and in vivo and in vitro experiments have validated that it has positive effects in reducing apoptosis, inhibiting oxidative stress, anti-inflammation, protecting mitochondrial function, and protecting the BBB. In summary, Bo-GEVs/XNJM has good neuroprotective effects, and provides an interventional method for the treatment of ischemic stroke.
期刊介绍:
The International Journal of Pharmaceutics is the third most cited journal in the "Pharmacy & Pharmacology" category out of 366 journals, being the true home for pharmaceutical scientists concerned with the physical, chemical and biological properties of devices and delivery systems for drugs, vaccines and biologicals, including their design, manufacture and evaluation. This includes evaluation of the properties of drugs, excipients such as surfactants and polymers and novel materials. The journal has special sections on pharmaceutical nanotechnology and personalized medicines, and publishes research papers, reviews, commentaries and letters to the editor as well as special issues.
