| 摘要 |
The present invention provides a therapeutic agent for Alzheimer's disease. The therapeutic agent contains membrane vesicles (exosomes) of adipose tissue-derived mesenchymal stem cells, and the membrane vesicles (exosomes) contain neprilysin. Through the research by the inventors of the present invention, it was revealed that exosomes secreted by human adipose tissue-derived mesenchymal stem cells contain neprilysin, which degrades amyloid-β as a pathogenic protein of Alzheimer's disease. When exosomes secreted by human adipose tissue-derived mesenchymal stem cells were administered to the brains of Alzheimer's disease model mice, the generation of amyloid-β was inhibited. |
