Nasal Spray Shows Promise in Alzheimer's Treatment
Researchers at Texas A&M University have developed a potential treatment for Alzheimer's disease using a nasal spray containing extracellular vesicles derived from human neural stem cells. This non-invasive method targets chronic neuroinflammation, reducing amyloid-beta plaques and Tau accumulation, and improving cognition and mood in animal models. The treatment alters microglia gene expression, reducing harmful inflammation while maintaining their ability to clear amyloid-beta. The approach could delay Alzheimer's progression by 10 to 15 years, with further studies planned to confirm its efficacy.
