Research Progress of nanostructured lipid carriers in brain targeted delivery systems

With the deteriorating global environment and the aging of society, central nervous system diseases have become a hot topic of social concern, and the blood-brain barrier is a major obstacle to the treatment of a variety of central nervous system diseases. Nanotechnology has been shown to be effective for the treatment of brain targeting, and nanostructured lipid carriers are a promising new nanocarrier delivery system. By reviewing the related literatures in recent years, this paper introduces the structural characteristics of nanostructured lipid carriers and BBB, summarizes the evaluation methods of drug penetration through blood-brain barrier, and reviews the application of nanostructured lipid carriers in the treatment of central nervous system diseases. The article aim to summarize the research progress of targeting delivery system of nanostructured lipid carrier in brain in recent years and its development prospect, so as to provide a more ideal therapeutic plan for the clinical treatment of central nervous system diseases with nanostructured lipid carrier in the future, and pave the way for deeper theoretical research and mechanism exploration.
